CONNECTIONS & SETUP
POWER ON/OFF MODES
The M8 can be congured for three power ON/OFF Modes: Manual, Audio Sens-
ing and AC/DC Voltage Trigger. Set the Power Mode switch to the preferred mode
and connect the Trigger IN if using the voltage trigger mode.
Manual Power
Manual power mode requires pressing the ON/OFF switch on the Front Panel to
turn the M8 ON/OFF. One press of the button will turn all eight amplier chan-
nels ON. Another press will turn the amplier OFF.
1. Set the Power Mode switch to ON as shown in Diagram 14. No other con-
guration is required.
2. To test, with the M8 connected to an unswitched 110V AC outlet, press the
ON/OFF button on the Front Panel. The ON/OFF button backlight will turn
ON (blue). After a few seconds the amplier will output audio to properly
congured channels. To turn OFF, press the button again, the audio
will be
cut from all channels, the ON/OFF button backlight will turn OFF.
Audio Sensing (Auto On)
Audio sensing will have the M8 turn ON when an audio signal is present on any
input, (Line, BUS or AUX). When an audio signal is detected, all eight amplier
channels
will turn ON. When no audio signal is detected for 5 minutes, the ampli-
er will turn OFF.
1. Set the Power Mode switch to Auto On as shown in Diagram 15.
2. Set the M8 Front Panel ON/OFF button to the ON (in) position.
3. Connect at least one audio source to any input to act as a trigger for audio
sensing.
4. To test, with the M8 and audio source connected to unswitched 110V AC
outlets, activate the audio source and play content, (CD, Tuner, etc). The
ON/OFF button backlight will tun ON (blue). After a few seconds the ampli-
er will output audio to properly connected channels. To turn OFF, stop the
audio output from the audio source. After 5 minutes of no audio input, the
M8 will turn OFF. (The ON/OFF button backlight will turn OFF.)
Voltage Sensing (Trigger)
Voltage sensing will turn the M8 ON when 3-30V AC/DC is present on the Trigger
jack. When a trigger voltage is detected, all eight amplier channels will turn ON.
When no trigger voltage is detected, the amplier will turn OFF.
1. Connect the 3-30V AC/DC Control Out on the trigger device to the 2.1mm
Trigger jack on the M8 Rear Panel as shown in Diagram 16. POLARITY: (DC)
Center (pin)=+3-30V; Sleeve= GND. AC voltage, polarity is non-critical.
2. Set the Power Mode switch to Trigger as shown in Diagram 16.
3. Set the M8 Front Panel ON/OFF button to the ON (in) position.
4. To test, with the M8 and trigger device connected to unswitched 110V AC
outlets, activate the trigger device so th
e Control Out is activated. The ON/

OFF button backlight will tun ON (blue). After a few seconds the amplier will output audio to properly connected channels.
To turn OFF, cut the Control Out voltage from the trigger device. The M8 will turn OFF. (The ON/OFF button backlight will turn
OFF.) If not, conrm trigger IN/OUT connections and polarity. Use a volt meter to conrm trigger voltage at the M8 and trigger
device.
