In large installations where multiple 800DAV amplifiers are required, the expansion bus may be used to
convey inter-amplifier control, and common IR control.
The source equipment audio and video inputs must be plugged into the first amplifier where they are
buffered and sent to the next amplifier in the stack. The maximum recommended expansion is eight units.
Fig 2 shows inter-connected amplifiers using an RJ45 expansion bus lead, and RCA leads for the source
Digital coax signals.
Amplifier Control using Ethernet, RS232 or USB may be connected to any one of the 800DAV’s in the stack.
If the media server is to be used on each 800DAV then Ethernet should be routed to each 800DAV, this is
because Ethernet access is not relayed through the Expansion bus.
