F1 812 hiss

SoundGeek ·
812 Owners I just purchased two new F1 812s. Does anyone else have a white noise type sound from 5kHz to about 9kHz when the F1s are turned on, with all inputs open, gains set to zero and input set to Line? It's low level and would not be noticeable once music or singing begins for a live band or DJing but it definitely raises the noise floor and would most likely be noticeable sitting close to the 812s in a very quiet room. (such as a conference or play/drama, etc.) Just curious if this is...

New Owner here with L1M and T1 WHAT IS THE SOURCE OF MY NOISE PROBLEM Questions: The noise level of the L1 S1 unit seems excessive with the power base trim set at 12 o'clock (5).

Yamaha Moxf8 and Bose L1 compact Noise

I'm getting a loud noise when connecting a normal 1/4 cable from the mono output on my Yamaha MoxF8 synth to input 2 on the Bose L1 compact (line setting). However, when I connect to the RCA input on the Bose using a 1/4 inch to RCA cable, it works fine with no noise. I use the Moxf8 connected to other sound equipment and don't have this problem.

T8 mixer overdriving channel noise

Superjazzman1234 ·
We used the the T8 mixer with two L1 M2 towers on probably a dozen gigs since we got it at the beginning of the month. We like it a lot.! We noticed that sometimes if the trim from channels are set too hot and the red LED peaks out for a second, it will not just distort that one channel, but it seems to take out the whole mix on the outputs for a split second with a loud static white noise. I know the solution is just to set the trim to a lower level but in the live performance world you you...

Buzz noise when plugged in power outlet - but fine when on battery

I've noticed when I plug my S1 Pro into an outlet, I get a lot of buzz/hissing sound when it's turned to the halfway point (even a bit under). I've tried a few power outlets along with a power bar and have the same issue. Is there a trick to minimize this? When it operates on battery, there is no hiss. I've also tried a power different cable so I don't think that's the issue. I realize it could have something to do with what instrument is plugged into it however, again, that noise doesn't...

Noise/ echoey sound while playing with macbook

Hello everyone, question from someone who doesn't know much about Bose yet...I play music for my dance sessions, and the studio has a Bose L1 with tonematch mixer. I also use a headset which I connected directly to the mixer. However, the sound was not good at all...echoey, people couldn't understand my words, and all songs with piano had a lot of noise and weird pitch. Even had to stop... So....wonder what I can do different for next time?! I have an old macbook, version 10.6. Is this the...

Re: White Noise When playing IPOD

Hi Kevin, Welcome to the Bose Portable PA Community. I'm glad you're here. The issue is probably with the cable. Use a cable like this: Hosa CMP-153 3.5 mm TRS to Dual 1/4" TS If you set the iPod to mono , then you only need to connect to one T8S input. Do NOT use a cable like this. Does that help? ST

Hi Shivani, Thanks for the information about the Bose equipment you have. We still need to know a bit more. It sounds like ToneMatch mixer may have some inappropriate settings.

Lower the setting for Mix until things sound better. Adjust Bright to suit your ear. Please tell us what you have connected to...

Hello! Here are more photos and info. This is the cable that is used to connect the computer to tonematch, on channel 1. Channel 2 is to connect to the headset, and main is connected to the speaker.

Re: Noise When Coming Out of Output Master on T1 Audio Engine

Hi Mike, There shouldn't be any hiss coming from the T1 Master Output. Try connecting the T1 Master Output to a mixer or powered speaker to see if there's a hiss. You can get a stronger signal from the T1 Master Output. Set the Master Output to Pre-Master Volume. This sends the full output of the T1 ToneMatch ® Audio Engine directly to the Master Analog ¼ inch jack. This might help, if you can change the input sensitivity of the transmitter so you don't clip the input. Here's how you make...

Re: Noise When Coming Out of Output Master on T1 Audio Engine

I Tried the exact method that you mentioned. That did not work. I tried it in Pre and post master volume. So I tried a little test I plugged the quarter inch plug into Pre-amp out under channel 1. Then I plugged another EW-100 into channel 2 and also plugged into Pre-Amp Out and the sound is superb. Of course the problem is I don't get the full mix. This is the question why can't I replicate the same test in the master without 30 to 50% hiss being introduced into my signal. Best Regards, Mike

Hi Mike, Did you try connecting the T1 Master Output to a mixer or powered speaker to see if there's a hiss? That's just for diagnostics. You got the same hiss both Pre and Post master volume? Good test. It's great that you get a clean signal from the Preamp Outs. It makes the issue (hiss from the Master Out) more baffling It sounds like it's time to call Bose Support.

Sorry to hear about the trouble. If this doesn't just end up being a power/grounding issue with the outlet in question, then this seems to be internal, and there is nothing we could try, short of what you have already tried. I suggest calling our Pro Portable support team at 877-335-2673 for a service solution.

Hi Simon, Congratulations on getting your L1® Compact. It's not unusual to hear some hiss if you have channel 1 volume turned on. It can be noticeable if you have nothing attached. If you can hear the hiss with both channel volumes turned all the way off, and you can hear it a more than a meter away, that is unusual.

Hi Jazz88, Thank you for joining the Community. I'm sorry this has been so frustrating for you. Let's start with a couple of key ideas: The connection from the T1® to the Model 1S Power Stand when using the ToneMatch cable is digital. It is independent of the Model 1S Power Stand Analog input. The Model 1S Power Stand Analog Input trim should always be set to 0 unless you have something connected to the Analog Input. You should be connecting your T1® using the ToneMatch port with the Model...

Hi SuperJazzMan1234, Thank you for joining the Bose Portable PA Community. Let's talk about the input trim. You're right, you don't want hard clipping on the inputs. Typically, you only need to set the trim once for a particular input. That is: you won't change it during a performance. When you want to change the loudness of an input, use the channel volume control for that input. Here's a video about gain staging. It applies to all the ToneMatch mixers - with one difference.

Re: Buzz noise when plugged in power outlet - but fine when on battery

Levko, have you plugged into different plugs in different buildings or all in the same building? In my experience some buildings have worse hum than others (maybe an issue with the grounding in their electrical system?). Not sure, but some bars I play at there is hum and others none at all! I invested in a really good surge protector with three independent grounds and it worked wonders.

I've just tried it in the same building. I got a higher end surge protector but it doesn't make any difference with the hissing. I just wasn't sure if there was a trick to an issue like this as I only use this in the same building for the most part. Thanks for your help!

Check the cable that connects the instrument to the S1. When plugged in, the A/C current flowing into the unit causes fields that aren't present when running on battery and can be picked up by a defective guitar chord or mic cable.

So many moving parts... :-) I've (rarely) heard a little hiss and hum from my S1s when plugged in but found that it was being generated by my QSC Touchmix (sometimes) because it went away when I muted the output from my mixer. Again, the major culprit is often a ground loop or some such which is why I try to plug EVERYTHING in the system to ONE grounded plug and use extension cables and power strips to distribute that ONE A/C source to every device.
