A 2-COLOUR LED
In MANUAL mode, the LED is lit “green” when the
amplifier is “ON”, receiving power from the power supply.
In TRIGGERor AUTOmode, the LED will be lit “red” until
the amplifier receives a music signal (auto) or a trigger
voltage (trigger), at which point it will turn “green”.
B POWER BUTTON
When in the ON position (button depressed), high
voltage power is received by the amplifier circuitry from
the power source. When in the OFF position (not
depressed), the amp is not receiving power and is not
operational.

C TRIGGER (INPUT & OUTPUT)
These 3.5mm (.125”) mini-jacks receive (input) a 5-24V
AC/DC trigger signal and deliver (output) the same trigger
signal (throughput) from an upstream component
( p r e a m p l i f i e r, surround sound processor (SSP), system
controller etc.).
D O N M O D E
With this three way switch, you may select the way in
which your amplifier is turned ON/OFF:
• TRIGGER ON:
This feature will allow your amplifier to be turned on or
off remotely via the Trigger described above (C).
• AUTO ON:
This innovative feature eliminates the need for a manually
operated power switch. AUTO ON simply turns the
amplifier on whenever there is an input signal on any
one of the channels. If no input signal is sensed after a
period of time, the amplifier will switch off automatically.
• MANUAL ON:
When in this position, the amplifier can only be turned
ON/OFF via the power switch on the front panel (B).
