the wire into the top of the receptacle, and tighten the connector. The same procedure
should be used for spade connectors.
4. REMOTE TRIGGER INPUT
Enables the Model 7.125 to be controlled by an external device with a 3.3V DC
minimum to 24V DC maximum trigger output. Connect the trigger output of the external
device to the TRIGGER INPUT of the Model 7.125 power amplifier. The Model 7.125
will automatically respond when the external device is powered on and off. When the
controlling device is turned on, the amplifier will turn on after a delay. This delay is
intentional and serves to protect the speakers while the unit stabilizes. During start-up,
you may hear relay clicking. This is normal operation.
5. DIMMER SWITCH (SEE FRONT PANEL DESCRIPTION)
6. MASTER POWER SWITCH
Connects and disconnects power from the AC Input Connector to the Amplifier Power
Supply. When this switch is on, the amplifier is in Standby Mode (See Front Panel
Description). When it is off, the front panel Power Button will not function. Set this
switch to off when making or breaking connections to the amplifier.
To power on the Model 7.125, press the rear panel Master Power Switch. When powered
on, the amplifier is in Standby Mode. There will be a delay from the time the power is
turned on until the power is applied to the speakers. This is normal operation and protects
the speakers from potential damage while the unit stabilizes. You may hear a relay click
during start-up, which is also normal operation.
Note: The class 2 wiring label is required for any unit in which the audio output power
exceeds 10W per channel under normal operating conditions or if the unit is intended to
be installed or connected by a skilled person.
When the Model 7.125 Master Power Switch is switched off or there is a power
outage, the state of the unit remains the same when power is restored. If in standby
mode when the power is removed, it will remain in standby mode when power is
restored. If the unit is in active mode (blue display is lit) and power is removed, it
will remain activated when power is restored. It is recommended that the Model
7.125 be set to Standby Mode before being powered off to prevent potential damage
to the unit or your speakers. If the Model 7.125 is not trigger-connected to a
controlling device, there is a potential for damage to the speakers if power is lost
and restored with the Model 7.125 in active mode.
