Can a Powered Mixer be used with L1's

Hey Brothers,

We are a 5 piece band 

  • 4 Vocals,
  • guitar,
  • banjo/guitar,
  • mandolin/guitar/ tenor banjo
  • electronic accordian with line out to the mixer and a bass output to  a separate bass amp

We have an L1 Model 2 and a Classic L1,  each with a seperate B1. 

Because of number of inputs we need to use an external mixer. Can we use a powered Yamaha mixer to send  L & R  output to each of the L1's please.

Thanks for your help

No one answered this yet? I'd say no unless you can shut down the onboard amps or maybe ....?... not plug it in.....will the mix section still function on a powered board not plugged in?...... pretty sure you don't want to run the power section with no load anyway. I'm thinking plugging a power amp into an L1 would be bad. Why didn't anyone answer this? Closed on Sundays....wait is this Chick fil-a?

 

Hi Maurie,

Thank you for joining the Bose Pro Portable PA Community.

Thanks for all the great information.

We need just a little more information.

Please tell us the model of your powered Yamaha mixer and a link to the owners manual would be very helpful. I'd be happy to look at that with you. You need line level outputs to safely connect to your L1®s. Do NOT connect the mixer speaker outputs to your L1®s. You could damage the mixer and the L1®s.

Hi Reed2go,

It's difficult to make generalizations about what will work. Serious damage could result if you run a powered mixer without speakers attached. Some powered mixers are okay to run without speakers.

I asked Maurie for a link to the owners guide for his mixer so we could talk specifically about his situation.

Do you have a mixer you would like to discuss? If so, please give us a link to the owners guide.

Thanks,

Hi ST,

The mixer is a powered  12 ch Sound Tech with a graphic equalizer. The member who mixes the sound has had it since the 90's I think , is very familiar with the settings for the band and wants to see if he can continue to use it with the two L1's.   He is away at the moment so I can't get a model number.  I had a quick hunt online for images that look like it  but no luck.  I guess getting a manual will be the same.

Any advice?

regards

Maurie 

Hi Maurie,

Without more details, I'm too cautious to offer advice. Here's why.

  • Running without speakers attached could damage the mixer
  • Connecting the mixer speaker outputs to the L1s could damage the mixer or the L1

 ST, 

I appreciate the cautious feedback and will try to convince our sound man to to move over to my unpowered Yamaha MG124CX mixer .  He is pretty wedded to the old Sound Tech and in particular the graphic equalizer he uses to tune.   

On that point , is it necessary to have  a GE ? How would we control errant frequencies with the MG12 panned L to the L1Classic and panned R to the L1 model II?

 Gary10113, thanks for taking the time to reply.

Hey ST,

A bit more information:

Our sound  man's mixer  is a  Soundtech PC800 .  Sorry no actual pic (or manual) as yet as he is still away but we found an old article on the mixer type.

He asks "In principle though it should not matter what the brand of mixer is??  The signal is an unpowered audio mix from a 1/4 inch jack outlet."

Will get back to you when he returns next weekend.

Thanks

Maurie

There's nothing wrong with sticking with what you know if you're happy with the outcome.

It depends the rest of the signal chain and the environment.

I have found the L1®s require less help to sound great than some other powered loudspeaker systems. I have graphic equalizers and I haven't needed them with the L1®s.  Your experience may be different.

Thanks for the article. There's not a lot of information out there for the Soundtech PC800.

Yes, if you can get a line-level (unpowered) audio mix from a 1/4 inch jack outlet that should be fine at the L1® side off things.

My concern is to avoid damage to the mixer by running it without an appropriate load on the powered amplifier outputs.
