POWER UP
With all cablings for input outgoing audio source, amplifier input and output channels connected, switch on the
power to the unit. Please use regulated 24V DC with min 0.5A rating. Unregulated power supply may cause fault
to the unit.
Once the power is on, all channels shall be at faulty position, and PT shall be sent to every individual channel. It
shall take approximately 30 seconds for the system to normalise. Remember all amplifiers shall be switched on
too.
TEST INDIVIDUAL WORKING FUNCTION
