Powering T1 from battery.

Hi there 

I have L1M2 B2 +T1 and S1 Pro 

I have a Behringer 1002B battery mixer for extra channels when using S1

When using ac power I prefer using T1 with external power supply over 1002B with S1 

Is there a way of powering the T1 using a battery?

I could use for example  a 12v 4a/h SLA battery and pure sine wave 600w inverter to 240v then step down to 18v using the Bose power supply but it seems a bulky solution  

I see the pins on the power supply output are +18 v Rtn and -18v rtn so its not a simple case of supply 18v DC 1A to two pins   I understand that the cable to the power stand also transmits digital audio signal but in the T1 S1 set up feature this is not required  

any thoughts?  Cheers Eric

Hi Eric,

We're always interested in helping our customers to use our products in innovative ways and to better their craft and performances. However, connecting a ToneMatch mixer to a power source other than a ToneMatch Mixer Power Supply connected to AC Mains is unsupported. If you damage the ToneMatch mixer, it won't be covered under warranty. We can't warranty against damage for circumstances we can't anticipate or that we can expect will harm the products.

Here's a link to the warranty information for Bose Portable PA products.

Here is some more information about alternative power sources.

Hmmm ... interesting question. I've seen folks on this forum who use battery power sources to power their L1 compacts ... so why not the T1?

I'd love to use my T1 with my S1 if I had a portable power source for the T1. Right now I'm experimenting with using the Behringer 1002B but can't eliminate the hum that I'm getting and it's really annoying.

I'd prefer to use my T1 if it were easy to power up ...

I don't have a hum running my Behringer 1002b and S1s.  I'm running a TRS 1/4" from each output through a balanced cable to an XLR into channel one of each S1.  I usually run the volume on the S1s at the detent (12 o'Clock) and do the mix on the 1002b...

How are you hooking them up?

I suspect it's easy to induce hum if you're going into the 1/8" aux input though...

I use the headphone out to a 1/8" adaptor from my Behringer Xenix throu a shielded 1/8" stereo cable to Channel 3 of my Bose S1 Pro, without him, @Eric SA . My setup does not produce audible hum. My guess would be the cable, or gain staging. Gain staging is very important to get great sound running my entire band through a Bose S1 Pro. That's why I use an active preamp DI box with each instrument. The additional EQ allows the dual use microphone/instrument channels to have independent EQ.

Thanks, @Chet ... I've tried connecting from the 1002B Main out to the S1 via TS (as per the Behringer manual) and TRS. Same thing - still get the hum.

Same cables going directly from my guitar to the S1 don't create a hum.

I pan the out from the 1002B L and R to the S1 ch.1 and 2. S1 is nearly always at 12 o'clock.

I usually run my SM58 to ch.1 on the 1002B (via XLR, of course).

I've tried going via TS from guitar to ch.3 on the 1002B and via TS/XLR through an ADI21. Either way I get a hum on my S1. Both guitars (Takamine acoustic or Godin A6 Ultra) have the same effect. I've tried a variety of TS cables too.

And I've tried the 1002B with power and on batteries. Same result.

I've already returned one 1002B to the retailer and am embarrassed to go back with the replacement as well!

That's why I would love to use my T1 if I could! (When I'm plugging into a power source I use my T1 - with my L1M2. To me, the T1 is the best mixer ever - for my needs. The S1 is usually out for busking or where I don't want to be bothered looking for a wall socket - but then I can't use my T1.)

The only reason I like to have a mixer is so I can have more than one mic and one guitar for use with the S1. I often have people wanting to singalong - so it's nice to have a separate mic for them.Or I can keep one mic which has a harmonica stand attached side-by-side with another mic - allowing me to switch easily when I need the harmonica.

And the Godin A6 has two output jacks. With a mixer I can have my Takamine (one output) and the Godin A6 (two outputs) connected without having to switch guitar cables. I can even keep my Uke plugged in and switch easily between instruments.

Hi Everyone

I understand the official Bose Position 

@ST I would never use modified sine wave because of noise and I do care about my sensitive electronics. Himlar a Bose does not appear to have an opinion on battery pure sine wave inverters, only modified, square wave (cheap) inverters.  I do use a 2200W Pure Sine Wave inverter and a 60AH AUSTRALIAN made Thumper battery pack with L1M2 B2 T1, effect Pedals etc.  The inverter produces clean regulated 240v AC Power just like mains. With plenty of power headroom.  I have absolutely no noise or performance issues. It’s a clean reliable but heavy solution.  I Prefer this to a petrol (gas) generator. I am interested though in comments about a pure sine wave inverter. Hilmar suggests that the Honda inbuilt Pure Sine Wave inverter is acceptable. I also understand it is impossible for a manufacturer to have an opinion on the many brands and combinations available in the world market particularly where warranty events may occur. Therefore there may be no official opinion other than the Honda Generator that has been evaluated  

@troubador@Chet and @RicI’m not having hum issues I use 6mm TRS from left main to my single S1 CH 2. Pan everything left. It’s handy for adding my Ukes and Wazinator Stoop box. I can EQ and forget.  I would prefer use S1 Ch 1 exclusively for my Martin DC28e with LR Baggs Anthem Pro.  Using S1 Guitar TM Setting as it sounds better than through the 1002B.  It’s not difficult to use the same guitar cable and switch between instruments but I have to tweak the volume and tone settings on the fly to balance sound.   

If I had a choice I would use T1 on battery over 1002b  The solution outlined above, smaller battery and small 300W pure SW inverter works but heavy and messy  

Thanks everyone
