Button function test

Verify that all the front panel buttons work well. See section on Input Selection and AMP# selection.
Verify that the Input type (Bal or S/E) and AMP# (1-15) are reflected in the RS-232 communication.

Trigger function test

For a CA2100
For this test you will need another CA(M)-XX00. Connect a switched +5Vdc signal (Trigger/IR box) to the
trigger-in input on the Trigger/IR board and from the trigger-out input connect a cable to the trigger-in input
of another unit. If the 2 amps were on Standby it should respond by powering up. If the 2 amps was already
ON, the trigger will be ignored. When you switch the trigger signal off, the both amps will power-down (back
to Standby). The trigger-out signal is just a copy of the trigger-in signal, it should measures about 0.2 volts
lower.

For CAP2100
Turn the CAP2100 on. Connect the Trigger out from the IR/Trigger box to the Trigger in from the unit.
Connect a 1/8 cable to your Trigger out of the unit. Put you multimeter to the other end of the of the 1/8
cable, you should see 0Vdc (relative to the output ground or the ground of the 1/8 cable) if your unit is OFF.
Turn on the IR/Trigger box. You should see on your meter about 10Vdc and see the unit turn ON. By
switching OFF the IR/Trigger box, the unit should turn OFF and your voltage should drop to 0Vdc. Repeat 2-3
times.

IR function test

For a CA2100
For this test you will need another CA(M)-XX00 and a Delta Classé remote control. Connect a cable from the
IR out from the trigger/IR box to the IR-in input of the unit and then, from the IR-out input connect another
cable to the IR-in input of another unit. Target the remote control to the IR/TRIGGER box IR eye and test some
IR functions (Power toggle, DIM, MUTE). Both of the unit should perform the asked IR function.
