Wire Side
1) Connect the following wires from the
provided power harness:
*This 12v+ remote output wire MUST be used for the aftermarket amplifier/DSP remote turn on for proper
functionality. If installing more than one Amp/DSP, a relay must be used for reliable system turn
on.
2) If using analog RCA outputs for signal to the amplifier, connections are made according to the chart below.
WARNING: Do not connect RCA cables to this interface until all amplifiers /DSP are properly grounded.
Failure to do this may cause damage to the interface and VOID the warranty!
3) If using Toslink for signal to the amplifier, connect the cable to the Toslink port shown on page 2. NOTE: both
analog and digital ouputs are aligned to produce sound simultaneously.
4) Connect the M.O.S.T. fiber optic cable to the M.O.S.T. 25 connector on the ZEN-25 interface.
