It has 8 analogue speaker outputs

Hi Richard -
There is lots of things that pan all around the room but the soundscape is
designed in pre production for this installation and then its just a
multichannel file (or seperate mono ones). Other installations I do are
interactive and so sounds are processed and panned in realtime around
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 m
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 interest
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
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.

The Raspberry PI route is interesting and relatively cheap.
There are now 8-channel "hats" like this one:

I see... But a standalone player is nothing else than a dedicated
computer, configured for the task of playing multi-channel audio. A
pre-configured PC can be configured to be idiot-proof with much more
options (EQ, etc) at the expense of more effort (I agree). The Cymatic

Hi Augustine,
It uses anything that's USB2 compatible. Stick, harddisk, MP3 player (if
the MP3 player has a disk-like operating mode)...
It's also a USB audio interface.
And there's a recorder counterpart, the LR16. No preamps, so it is very
affordable.

Hi Augustine,
The Cymatic LP16 has 16 outputs and I believe it can be synced to a second
one. If not, there's the 24 channel Utrack 24 that's also a recorder:
