Hi Kristy,

Welcome to the Bose Portable PA Community. I'm glad you're here.

Is it possible that someone turned down the trim controls?

Please check out this article with videos.

T1 Gain Staging

You didn't mention what you have connected to the T1; an L1 Compact or L1 Model 1S or L1 Model II?

If you are connecting to an L1 Compact, you will get a stronger signal  if you use a 1/4" (6.3 mm) Tip-Ring-Sleeve cable from the T1 Master Output ot L1 Compact Channel 2. And be sure to set the ToneMatch Switch to Line Level (the down position).

Does that help?


Hi Kristy,

When you sing loudly or turn up the volume on the ipad, do the trim lights (about the knobs) turn red?

How are you connecting the T1 to the L1 Model II Power Stand. Are you using the ToneMatch connector (round barrel, square connector inside), or a 1/4" (6.3 mm) cable to the Analog Input?

A friend of mind told me his Bose L1 sounded terrible. He did not have any of the channel presets set up correctly. Once he got that straight it sounded great. I had a volume issue with my backing tracks on channel 4/5. I had the preset on DJ/Playback. It turned out to be a bad cable. You have to have a good quality Y cable (left/right 1/4 inch mono) to stereo mini jack. A couple of other times one of the 1/4 in. was not all the way in or the mini was not making good contact with the iPad. As they say, it's usually something simple and in my case it was.

Hi guys thanks for the replys, ok so ive already checked all the setting and they are all fine. The trim has been set to this level so it only turns yellow never red! The problem seems to me that everything is turned up too loud!!! You know then you turn something up so loud it distorts, well it sounds like that only the volume isnt really loud!! I have also just changed out my cables to be sure its not them.... i have decided to check the input signal strength ive just ordered a little headphone pre amp for my phone so i can turn that up and turn down the bose and then ive ordered a cloudlifter for my mic to boost the gain so hopefully i can the turn that down too in the hope that when the bose is turned down it wont distort so much but i will also get more volume! I dont know if that makes sence...

Hi Kristy,

Let's do some diagnostics.

Do you have an ordinary wired microphone kicking around? If so, please connect that to T1 Channel 1.

Use close mic-technique (microphone within an inch of your lips) and sing as loudly as you can into it.

While doing that, set the input trim so you get solid green and flickers of yellow, not red.

Can you get the volume up louder than with the radio mic in T1 channel 2?

What's the trim position (2:00 o'clock, 3:00 o'clock?).
