Hi.  Need some help on setting up sound for dancers in a gym.  

For the last 9 years, I have used 2 L1 compacts with no subwoofer and no mixer.  Sound comes from an iPad, through the first L1. The 2 speakers are placed 20 feet apart, facing the dancers and facing away from the audience who are in bleachers.  The 2nd L1 compact has a 2nd iPod that plays music in between performances, at a lower level and only from that speaker.  

Thanks for the detailed background.

What style of music are you playing through the iPad?

What I've experienced is distortion on the 2nd speaker when I play high volume from the main (first) L1.

The volume settings on the first Compact will raise and lower the output to the second L1® Compact. Set the volumes on the first L1® Compact and then bring up the level on the second L1® Compact to set the relative volumes between the two systems. If you set the volume controls of the first and second Compacts to the same level, the second L1® Compact could be louder. 

Source: L1 Compact Daisy Chain

It IS possible you can experience distortion if the volume control on the second L1 Compact is set the same as the first. To avoid that distortion, turn down the volume control on the second L1 Compact.



 I am ready to upgrade my system and was going to purchase 2 F1 812 speakers and 1 F1 subwoofer.  My thought was to move all the speakers off to 1 side of the gym and just manipulate the 812 patterns to reach both the dancers and the audience.  

For best results, you want to place loudspeakers where you need the sound.  If you put the loudspeakers (closer) together and off to one side, you can limit their effectiveness in covering a large space. If your gymnasium a large reverberant space you want to place the loudspeakers where you need the sound - close to the listeners (dancers and/or audience). This should allow you to run at lower volumes while maintaining clarity and intelligibility and reduce the amount of reverberation.



Are there significant advantages to upgrading to this system?

With the F1 Model 812 systems you will get more volume, wider frequency response (more bass), and tighter pattern control. (Technical comparison at the end of this post.)

You have anticipated the greater volume and better bass response. You will also get better control over where the sound travels. This is important in large reverberant spaces.

The L1 Compact projects sound very well from side to side. The F1 Model 812 is more directional - you will more sound in front of the loudspeakers than off to the sides or behind them.

Good:
Less sound bouncing around the gymnasium in ways you don't want.

Not so good:
If you have the F1 Model 812s facing the dancers (facing away from the audience), the audience will not hear the loudspeakers well, perhaps not even as well as when using the L1 Compacts as you are now.

Questions:
Can you put the F1 Model 812s behind or beside the dancers facing both dancers and the audience?

Will you keep the L1 Compacts? If so, you can have the F1 Model 812s facing the audience and the L1 Compacts facing the dancers.



 What is the advantage of adding a mixer?

You will have more control over the volume for each loudspeaker.

Would it eliminate that distortion?

Yes, although the distortion is the result of daisy chaining the L1 Compacts and pushing the second L1 Compact beyond its limits. The mixer will make it easier to avoid the problem, but it won't make the second L1 Compact louder than the first (without distortion)

One option I have is just purchasing 1 F1 812 and 1 F1 sub and using 1 or both of my L1 compacts in addition.  Just trying to eliminate distortion but definitely need to add the sub for more base.  

Depending on the style of music you are playing - you may not need the F1 Subwoofer.  What style of music are you playing? What style of dance is this?



With the new set up, (the 3 sound pieces would be close together instead of 20 feet apart)

If you don't need the F1 Subwoofer, you can keep the L1 Compacts where they are (20 feet apart facing the dancers). Put the F1 Model 812s on stands behind the L1 Compacts (facing the audience).  The dancers will still hear the bass from the F1 Model 812s.

A mixer isn't essential to get everything to work well, but it will make things simpler.

- I'm not sure the best way to arrange them an if they would need to be spread apart with the new sound pattern options.  Please help!  Also, I'm not a sound person - just a dancer/business owner.  Thank you.

I've described general principles, but it would be helpful to know more about your situation. Please tell us the style of music, the style of dance, and the dimensions of the gymnasium, and the number of people in the audience.

Thanks,

ST

Thank you Rob. I’m thinking of purchasing just one F1 812 and the subwoofer at this point. And possibly adding a mixer to play the 2nd source, in between competition routines...I do find myself running between the 2 speakers during the event, trying to fix the sound a lot.

If you have been getting by with just the compacts, one F1 with sub will probably do it in conjunction with the L1 compacts.  I think ST is spot on with your distortion issues.  Solve that and I imagine you will be good to go.  The world of sound is slippery.  The best you can do is learn the principles and then use your ears.  I think Bose does a good job of jump starting you with the tone match mixers.  

First of all, thank you so much for your detailed reply, ST.  Very helpful.  This is a dance competition, so the most important direction of the sound is to the dancers.  It's all styles of dance, so all genres of music.  I should also add that the schools provide their music to me and a lot of times it's recorded too hot or too low and I am constantly adjusting the volume on the main L1 compact (Whitney) I've named the 2 speakers Bobby & Whitney, fyi. Anyway, at the start of each dance, I am adjusting Whitney.  At the end of each routine, sound comes direct from an iPod to Bobby, and at a lower volume, so another adjustment.  In the past, we've received feedback that the dancers don't "feel" enough OOMPH during the POM and HIP HOP categories; this is the main reason for the upgrade and/or the subwoofer.  In theory, I can bring both L1 compacts AND the new 812 and subwoofer into the gym.  The problem I have with the current set up, and adding more to it, is that it obstructs the audience view to the performance, as the speakers are in front and because they can only be so many feet away (think foul line to foul line in the gym, but probably even less) to accommodate the cords.  I had them up front all these years because that is where my music source is, the announcer, my judges table, and me - running to adjust volume.  I could easily move the whole set up to the back, as my mic is wireless, but would have to just work out the logistics of how far I can run a mixer (along the side of gym?) and be able to still communicate with the announcer, as my earphones never do the job for me.  I could also have the whole set up on the side of the gym (stage left).  This is a standard high school gymnasium with 1 level, and bleachers at all 4 corners.  Approximately 1,000 people in the gym at one time.

Attached is the gym set up.  The 2 L1 compacts are connect with one cord but they both come out of the same power outlet (I vaguely remember someone in the past saying that could also lead to distortion?).  The mic base comes from table 11.  The music comes from Table 12, directly plugged in.

Just a thought. 

I've done sound for theatrical performances using "canned" music (from a computer - with my Bose 802 based sound system) and the first thing I did was use a free audio editing program, Audacity to NORMALIZE all of the audio tracks so they had nearly the same "loudness" when played back.

Depending upon the length of performances, wireless connection is possible between a mixer and the speakers using xVive U3 wireless ($200 per channel) - battery life is at least 2 hours but others are experiencing much longer use times.

Yes, that’s an option. I used to use Audacity but switched to Sony Soundforge for editing. However, I really hate to add the additional task of sound editing everyone’s music prior to the event, as I am doing so many other things.  And sometimes music for soloists is just softer in general. I don’t mind adjusting (or having someone else adjust) as they compete. But thank you - I will still consider this option!

Hi Apple,

Here are a few ideas.

Legend:

F18 for post F1 Model 812 

Compact for post  L1 Compact

The green arrows indicate direction of sound from back to front

First of all, thank you so much for your detailed reply, ST.  Very helpful.  This is a dance competition, so the most important direction of the sound is to the dancers.  

We'll aim the F1 Model 812 systems at the dancers.

It's all styles of dance, so all genres of music.  

I should also add that the schools provide their music to me and a lot of times it's recorded too hot or too low and I am constantly adjusting the volume on the main L1 compact (Whitney) I've named the 2 speakers Bobby & Whitney, fyi. Anyway, at the start of each dance, I am adjusting Whitney.  At the end of each routine, sound comes direct from an iPod to Bobby, and at a lower volume, so another adjustment.  

We can solve all of that with a mixer that has a built-in  compressor/limiter, like a Bose T4S or T8S.  Or - as mentioned in previous posts, by running all the music through a program like Audacity. I understand, that's more work and won't help you if you can't get all the music well in advance.

In the past, we've received feedback that the dancers don't "feel" enough OOMPH during the POM and HIP HOP categories; this is the main reason for the upgrade and/or the subwoofer.

The F1 Model 812 systems have significantly more bass response than the L1 Compacts. I would start with two F1 Model 812 systems.  Given the size and shape of the space, I don't think you'll be happy with just one F1 Model 812.
If you're not satisfied with the bass, then you can get the F1 Subwoofer.

 In theory, I can bring both L1 compacts AND the new 812 and subwoofer into the gym.  The problem I have with the current set up, and adding more to it, is that it obstructs the audience view to the performance, as the speakers are in front and because they can only be so many feet away (think foul line to foul line in the gym, but probably even less) to accommodate the cords.  

While the sight lines are important, since the dancers are moving around I hope this won't be a huge issue. Notice I have put each L1 Compact back-to-back with the F1 Model 812 systems. This should minimize the obstruction for the audience and also, make the wiring simpler.  You'll have just one set of cables to each side of the performance space. 





I had them up front all these years because that is where my music source is, the announcer, my judges table, and me - running to adjust volume.  I could easily move the whole set up to the back, as my mic is wireless, but would have to just work out the logistics of how far I can run a mixer (along the side of gym?) and be able to still communicate with the announcer, as my earphones never do the job for me.

Let's talk about cable runs.  
If you use a mixer with balanced outputs (most modern mixers like the Bose T4S/T8S do), then you can run balanced cables hundreds of feet without problems.  You can get 100 foot cables for under $50

You'll need some adapters like this if you use a Bose T4S mixer. 

Click the picture for details.

Cables with adapters like these will connect the mixer to the F1 Model 812 systems. 

Then, you can run a separate set of cables from the T4S/T8S Aux outputs to the L1 Compacts. This will give you the ability to control them independently from the F1 Model 812 systems.

For simplicity, I would approach this differently. One each F1 Model 812 run the LINE OUT to the L1 Compact behind it. Then, as you raise or lower the volume of the F1 Model 812 systems the L1 Compacts' volume will follow.  Yes, that's very similar to what you're doing with the two L1 Compacts now. The difference is, you will set the input levels on the L1 Compacts once.  There will be a very noisy one-time setup, and after that, you'll have a setting you can use every time.

You can use cables like this:

click the picture above for details.

OR

As mentioned in previous posts, you can run wireless.

 I could also have the whole set up on the side of the gym (stage left).  This is a standard high school gymnasium with 1 level, and bleachers at all 4 corners.  Approximately 1,000 people in the gym at one time.

Thanks for that information. It helped me to visualize how large the performance space is, and led to the suggestion to have two F1 Model 812 systems.

Attached is the gym set up.  The 2 L1 compacts are connect with one cord but they both come out of the same power outlet (I vaguely remember someone in the past saying that could also lead to distortion?).

It's good practice to have both L1 Compacts connected to the same power outlet. No, it's not likely this could lead to distortion.

 The mic base comes from table 11.  The music comes from Table 12, directly plugged in.

What do you think?

Okay, I can try this set up.  I should have mentioned that 90% of the spectators are in front (behind tables 10 & 11).  But I could just angle the back to back sets more forward.  Also, in this scenario, I would need to run the super long cables from one side of the performance floor to the other, correct? (L1 + 812 Stage Left to L1 + 812 Stage Rt).  See diagram. And how many of each cables do I need?  Does the T4 Mixer just get manually connected to the first speaker set?  I see that it comes with one "ToneMatch cable" but wasn't sure if I needed to purchase additional ones.  I know I would need a 100 ft (or so) cable to go from one speaker "set" to the the other, across the front of gym, but which cords should I purchase to connect the sets together (ie: first 812 to Whitney on Stage L)?  Sorry for all the questions.  I don't have a technician brain...and I'm 9 months pregnant so that doesn't help right now...

"Each routine is 2 minutes but the event is all day... 10 am - 5 pm. Wonder if that’s an option..."

Wireless wouldn't work well for that unless you could detail someone to turn the receivers at the speakers and the transmitters at the board off then on for each routine.  ;-)

Maybe you could request those providing the music to normalize their tracks BEFORE giving them to you?  Enough may accommodate you to lower your workload.

Let's put the L1 Compacts closer to where they are needed. I moved them behind tables 10 and 11, facing the spectators.  

Please disregard my note about about connecting the F1 Model 812 line outs to the L1 Compacts. We won't be doing that now.  More about the connections later.

Yes, you're going to have some long cables. A basketball court is 50 x 84 feet

See diagram. And how many of each cables do I need?  Does the T4 Mixer just get manually connected to the first speaker set?  I see that it comes with one "ToneMatch cable" but wasn't sure if I needed to purchase additional ones.

You won't use the ToneMatch cable. That's only used when connecting to an L1 Model II or L1 Model 1S.  

 I know I would need a 100 ft (or so) cable to go from one speaker "set" to the the other, across the front of gym, but which cords should I purchase to connect the sets together (ie: first 812 to Whitney on Stage L)?

Now that we've moved the L1 Compacts behind tables 10 and 11, we will NOT be connecting the F1 Model 812 systems to the L1 Compacts. 

We will run separate cables from the T4S to the L1 Compacts.

 Sorry for all the questions.  I don't have a technician brain...and I'm 9 months pregnant so that doesn't help right now...

Please tell me how many sound sources you will have. For example

  • Wireless microphone (for you)
  • Wired microphone for announcer/judges
  • iPod for dance music
  • anything else?

Then I can tell you in more detail how we would make all the connections.

Thanks,

A. Just 1 wireless mic.  The announcer uses it for most the day - I just use it periodically.  (In the past, I had it the receiver on Table 11 with a mic cord from receiver to main L1 compact) 

B. Main iPad (playlist for each dance routine) to be played through all speakers, will be on Table 12.

C. iPod of music to play in between routines so there are no awkward silences. Played at lower volume. In the past this was directly attached to 2nd L1 compact and only came out of at speaker.

That's it for sound sources!  I had all wires & power strips, taped down under tables 10 & 11.  So in your new scenario, my two L1 compacts will be  in the same spot they have been for the last 9 years (relatively, just behind table instead) and we would be just adding an 812 on each of the sides of the gym.  Okay let's move forward with this set up...

I'll be at the tabulators' table, Table 11. The main iPad will be at table 12, with the announcer.  Once announcer uses mic; the other just presses play.  All music is given to me prior to event and is played from an iTunes playlist in that main ipad. The Mixer can be at table 12 with the rest of sound (and I will have to show them how to use it) or it can be with me at table 11 - whichever makes set up easier.  Not sure where iPod #2 would be in this scenario...if it just gets connected to the mixer now?

Thank you.  That's extremely helpful.

First, you'll need T4S ToneMatch mixer plus the optional ToneMatch mixer power supply

Two F1 Model 812 systems with speaker stands.

Bose doesn't sell the speaker stands. Check out these lift-assist stands.

To connect the T4S to the F1 Model 812 systems and L1 Compacts, you can use cables like this.  

  1/4 inch (6.3 mm) Tip-Ring-Sleeve to 1/4 inch (6.3 mm) Tip-Ring-Sleeve

You need four cables. They come in various lengths.  To be safe, you could get four - 100-foot cables.  Here are the cable runs (notice the numbers, 1-4)



You might be fine with

  1. 100-foot cable
  2. 50-foot cable
  3. 75-foot cable
  4. 50-foot cable



Connect to the T4S

I'll talk about the T4S inputs in the next post.

Hi Apple,

Here are the connections for your sound sources.

  1. Wireless microphone
  2. iPad
  3. iPod
  4. Spare in case you want to connect another microphone or device



Cables

Wireless microphone

Your receiver may have a 1/4 inch output or XLR output or both.

If the output is XLR use a cable like this.

XLR microphone cable

If the only option is a 1/4 inch jack, use a cable like this.

1/4 tr1/4 inch (6.3 mm) Tip-Ring-Sleeve cable

Hosa HSS-005 REAN 1/4" TRS to REAN 1/4" TRS Pro Balanced Interconnect, 5 Feet

iPad

We will set the iPad output to mono.

  • Launch the Settings app on your iPad
    • Tap General.
    • Tap Accessibility.
    • In the Hearing section, turn Mono Audio On

Use a cable like this

1/8 inch tip-ring-sleeve to dual 1/4 inch tip-sleeve

Connect the black end to the iPad headphone output. If it doesn't have a headphone output, use an Apple Lightning to 3.5 mm Headphone adapter.

Connect the grey end to T4S channel 3.

You will not use the red connector. Put some electrical tape over it.

Connect the grey end to T4S channel 2.

iPod

We will set the iPod output to mono.

  • Launch the Settings app on your iPod.
    • Tap General.
    • Tap Accessibility.
    • In the Hearing section, turn Mono Audio On

Use a cable like this

1/8 inch tip-ring-sleeve to dual 1/4 inch tip-sleeve

Connect the black end to the iPod headphone output.

Connect the grey end to T4S channel 3.

You will not use the red connector. Put some electrical tape over it.

Ideally, you would have all the devices will be connected to the same AC power source (T4S, F1 Model 812 systems, L1 Compact systems).  In practice, because of the connections we're using, you should be okay if it's not feasible to have all the power coming from one AC power source.

That covers all the physical connections.

I can help you to set up the T4S, but I want to check in. Do you have any questions about thing so far?

Hi Apple,

I'll start with each input, and when we've done this part, you'll have sound coming through the F1 Model 812 systems.

T4S

The numbered outputs below (1 and 2) are the T4S Main Outputs.

Connect 1 to the closest F1 Model 812 (the one to your right)
Connect 2 to the farthest F1 Model 812 (the one to your left)



F1 Model 812 settings

Connect the T4S Main outputs to the F1 Model 812 Channel 1 input.

Use these settings.

F18 from T4S





Wireless microphone

This is connected to T4S channel 1

Please watch this video done with a T1 (the principles are the same for the T4S)

ToneMatch Preset

For now, you can set the ToneMatch Preset to 
Category: Vocal Mics
Preset: Handheld Mics

Please tell me the make and model of your wireless microphone. I may be able to suggest another ToneMatch Preset.

Tone Controls

You may want to change the tone (Low, Mid, High)

  1. Press the CHEDIT button for channel 1
  2. Turn the Rotary Selector to zEQ
  3. Turn the knobs to decrease/increase Low, Mid, High frequencies to suit your ear

Effects and other settings

For your application, you shouldn't need to change anything else (e.g., ParaEQ, Comp/Gate, Mod, Delay, Reverb). We will do something with PAN/AUX and Comp/Gate later.

Turn the Master Volume to 12:00 o'clock

Turn up T4S channel 1 volume and listen to the sound of your voice.

iPad and iPod

Repeat these steps for the iPad and iPod in channels 2 and 3.

Turn up the volume on the iPad and iPod to about 80% of the maximum. To do that, turn the volume all the way up, then tap the volume down button three times.

While playing music, turn up the trim controls so you see solid green, but no red.  This will probably be around 2:00 o'clock.

ToneMatch Preset

Set the ToneMatch Preset to 
Category: Category DJ/Playback
Preset: Flat, zEQ Controls

While playing music, listen as you change the Preset to Low Volume Music. Then try High Volume Music.  Choose the one that sounds best to you.

Tone Controls

You may want to change the tone (Low, Mid, High)

  1. Press the CHEDIT button for channel 2 (iPad) or 3 (iPod)
  2. Turn the Rotary Selector to zEQ
  3. Turn the knobs to decrease/increase Low, Mid, High frequencies to suit your ear

Effects and other settings

For your application, you shouldn't need to change anything else (e.g., ParaEQ, Comp/Gate, Mod, Delay, Reverb). We will do something with PAN/AUX and Comp/Gate later.

Turn the Master Volume to 12:00 o'clock

Turn up T4S channels 2 and 3 volume and listen to the music.

At this point, you should have the microphone, iPad and iPhone working and sounding really good.

More to come.

Hi Apple,

Now we'll connect the L1 Compacts.

T4S

The numbered outputs below (3 and 4) are the T4S Aux Outputs

  • 3 is Aux 1
  • 4 is Aux 2

Connect 3 to the closest L1 Compact (the one closest to the right F1 Model 812)
Connect 4 to the farthest L1 Compact (the one closest to the left F1 Model 812)



L1 Compact settings

Connect the T4S Aux outputs to the L1 Compact Channel 2 inputs.

Use these settings.

You won't hear any sound yet because we haven't routed anything to the Aux Outputs yet.

PAN / AUX

The following instructions look like a lot, but you should only have to do them once. You should be able to do all of this just a few minutes.

Microphone

  1. Turn the Rotary Selector to PAN/AUX
  2. Press the channel 1 CHEDIT button
  3. Under the display, turn the Menu button (leftmost button)
  4. Select Aux Send 1
  5. Press the Level button (middle button)
    1. Set the Level to 100%
  6. Turn the Tap button (rightmost button)
    1. Set the Tap to Post: After Fader
      Now repeat for Aux Send 2
  7. Turn the Menu button (leftmost button)
  8. Select Aux Send 2
  9. Press the Level button (middle button)
    1. Set the Level to 100%
  10. Turn the Tap button (rightmost button)
    1. Set the Tap to Post: After Fader

iPad

  1. Turn the Rotary Selector to PAN/AUX
  2. Press the channel 2 CHEDIT button

Repeat steps 3 through 10 above

iPod

  1. Turn the Rotary Selector to PAN/AUX
  2. Press the channel 3 CHEDIT button

Repeat steps 3 through 10 above

Now you should have sound coming through the L1 Compact systems too.

You can fine-tune how much sound is going to the L1 Compacts by adjusting the Level (see step 9) above. 

To make quick changes:

Adjust the volume for the F1 Model 812 systems using the Master Volume. The Master Volume does not affect the sound to the L1 Compacts.

Adjust the volume for the L1 Compacts with the channel volume controls for channels 2 and 3. This will also affect to volume for the F1 Model 812 systems. You can compensate by adjusting the Master Volume. This is not as complicated as it sounds. Practice this before the competition starts.



We'll set up the COMP/GATE controls later.

Hi Apple,

Let's level out the volume levels for the music from the iPad and iPod.  This assumes you have the output of the iPad and iPod at about 80% (three taps down from maximum volume).

These are all one-time steps.

  1. Press the channel 2 CHEDIT button
  2. Turn the Rotary Selector to COMP/GATE
  3. Under the display, turn the Type button so you can see the menu
  4. Select Limiter
  5. Set the Thresh to -10.0dB
  6. Leave Gain at 0.0db
  7. Press the channel 3 CHEDIT button
  8. Under the display, turn the Type button so you can see the menu
  9. Select Limiter
  10. Set the Thresh to -10.0dB
  11. Leave Gain at 0.0db


If you need more aggressive throttling of loud tracks, set try setting the Thresh to -20.0 dB.

Now we'll set channel 1 to automatically mute the microphone when you are not speaking directly into it. This prevents amplifying background noise or casual comments you had not intended to amplify.

  1. Press the channel CHEDIT
  2. Turn the Rotary Selector to COMP/GATE
  3. Under the display, turn the Type button so you can see the menu
  4. Select Noise Gate
  5. Set the Thresh to -40.0dB
    • If you find this cuts off the microphone even while you are speaking directly into the microphone try setting the Thresh to -50.0dB
  6. Leave Ramp / Speed at 50%

That should get you going.

When is the next competition?

Hi ST! I did a test set up of all of this and everything works great EXCEPT when I have all 4 speakers on, the L1 compacts make a buzzing sound that is heard from the 812 speakers.  When I unplug both L1 compacts, the sound disappears.  This is the buzzing I've heard over the years when I run this event.  Thoughts on what could be causing this?

Are the L1 Compacts connected to the same power source (power bar or circuit) as the F1 Model 812s?

Are the cables running to the F1 Model 812 systems and the L1 Compacts 1/4 inch (6.3 mm) Tip-Ring-Sleeve like this?

Here is some more information about sources for buzzing.

Hi Apple,

I'm not convinced you need direct boxes for the L1 Compacts.

Does the buzz persist when you have everything plugged into the same power source?

Are any of the signal cables that connect the F1 and L1 Compact systems run parallel to power cables?
