Hi Augustine, this sounds like an interesting application. I was
recently at the Buddhist rhythm garden in Hong Kong and experienced a
multi-speaker system within the garden - it was very effective. The
UTrack24 looks great, and affordable. Do you control the internal DSP
mixer to have sounds moving across speakers or would this be pre-mixed
into the channels you send? I have been using mixer matrices within the
N-DAC8s and SPK-4Ps to provide immersive effects. The nice thing here is
that you have a standard protocol to enable this. To use the N-DAC8s for
your application you would indeed need to have 3 x N-DAC8s ($900) and a
computer.

Hi Richard and Guillaume,
Interesting stuff. Two things to note - the installation is in a tropical
botanic garden so I am using a certain type of speaker that is pretty
resilient (used in saunas etc) whci is passive (for obvious reasons) and
connected by speaker cable . The AVB amps sound interesting - any links to
the highest channel count ones ? I am not quite sure what advantage 4 * N-DAC8
($1200) + computer ($ ???) would get me over one Utrack 24 or even a Joeco
other than the fact its connects via ethernet rather than USB , bearing in
mind that the speaker will be connected analogue via a a couple of
multichannel amplifiers.....

Yes, I agree with Guillaume - AVB is a good option. miniDSP sell an 8
channel box AVB box, the N-DAC8, for $299.
With three of these you have 24 channels, and they all run off the same
network clock. You would also need a small (4/5 port) switch.
A more expensive, but also easily configurable option is their SPK-4P
Power over Ethernet option ($395). For 22 channels, you would then have 22
speakers connected to a 24 port switch. Power, audio, and control then all
travel over one cable, which makes for easy configuration. Again, all
speakers are synced to the same network master.

Aside from dante, AVB is another option for multichannel audio over
ethernet.
It is now available as standard (and for free) in any Mac running a
recent os, and several options for avb enabled amplifiers are available:
biamp, crown, l-acoustics to list a few.
If converters are required, the Motu AVB series can help, and is
relatively inexpensive.

see my post before last for what went wrong. How much are the Joecos ?

However, if you go the Dante route, you might as well use an old Minimac
with a virtual soundcard (if 32 ch out is enough) and an appropriate Dante
converter. Should be cheaper, if you have the Mac lying around, and no less
robust if the hardware is otherwise ok.
