The I2S module can be installed instead of the USB module. A
new technology is used to make the I2S data format more reliable. Actually,
this format was made for internal use and not able to drive long data lines.
Sonnet is using a kind of data transport based on the typical impedance of
a standard UTP cable. By using this technology, it is important that both
transmitter and receiver is made for this quite heavy load of 100 Ohms. As a
result, lengths of 30 meters between source and receiver can be
used without loss and jitter.
The I2S module is dedicated for Sonnet products like for
instance our upcoming Hermes. However, in some cases by removing four jumpers
on top of the module it will act as a high impedance receiver and therefore
more flexible to match with other products. Still Sonnet Digital Audio cannot
guarantee the correct behavior in conjunction with other systems. If you have
any doubts about the correct match with our products don't hesitate
to contact us.
Like the standard USB option our dacs can
be ordered including the I2S module.
