Thanks for all the replies on this subject.
I think that we will put together something with switching at the
pre-amp stage rather than inside the squeezebox. I think that as a
first try we will simply follow Phil's suggestion of two identical

I don't think you understand the requirement. 2 Touches need to drive 2
amps and 2 pairs of speakers. Then you need a means of (easily) toggling
between 1 Touch playing and the other muted and then that

You can't do that easily with JUST 2 Touches because they will respond

Then you'll have a problem matching the volume.
Two synched Touches, and some kind of SqueezeOS hack, or SBS hook, to
mute them selectively, could well be the cleanest solution in some
ways.

Why would there be a matching problem with one amp or one pre-amp?

It can't be easily done without bespoke coding - there is NO way to

remote... but you need the 2 Touches to respond to 2 different IR
command sets.
Also, the approach would then be 100% dependent on

Because different speakers have different sensitivity, and matching the
volume after the power amp stage isn't desireable (doing anything to the
signal after the power amp stage generally isn't desireable).

Why not just have us input 1 on amp 1 and input 2 on amp 2?
Then if you chose input 1, amp 1 will play and vice versa.
No need for remote programming at all then.
True - yes, you are correct that would work.

hi, just to clarify you can split the signal and run into a DAC with two
coax inputs OR even more simply run coax and optical into the same DAC.
Assuming you want to aid switching by staying exactly in the same
position, then a remote control switching is useful. Buy a DAC with
remote for as

Or, if you feel like doing some hardware DIY, make an opto-mechanical
TOSLINK switch from some optical cables, an RC car servo, some RC car

Hi all,
I have a slightly strange requirement which I think might be fulfilled
using the SB touch plus a little bit of fiddling with the software.

I work for a loudspeaker company (KEF Audio) and we have been using the
slimserver/squeezebox system in our listening rooms

I was hoping for something a little bit cleaner though, easy for any of

Actually no, the mute does not sync
Note also that the Touch doesn't have a USB out for a DAC. You would
have to continue to use SPDIF which presents another challenge to your
idea of using 2 DACs simultaneously with the one Touch
