6.4. Amplifier Power Control

6.4.1. Master Power Switch

The master power toggle switch at the back of the unit controls the main power.  If this is turned off the amplifier 
will not respond to any control method.  This switch should be left in the ON position after installation and setup is 
finished unless the amplifier will not be used for an extended period of time or is being serviced.  For everyday use, 
decide on one of the options below.

Use the Power Mode switch (below the Master Power switch) to select the desired power control mode.

6.4.2. Front Panel Power Button

When the amplifier is powered on, the power button will illuminate solid blue and the channel LEDs should 
all illuminate solid blue (if any channel LED illuminates RED, remove power immediately and consult the 
Troubleshooting section to diagnose the issue.  This indicates that a channel is in safe mode.).  When it is off the 
power button will be red and the channel LEDs will turn off.

Note:

 

The front panel Power button only controls the amplifier when the power mode is set to Power ON.

6.4.3. Power ON Mode

For manual control of the amplifier power state, set the Power Mode switch to POWER On. Press the front panel 
Power button to toggle between Stand-by and On.

6.4.5. AUTO (Audio Sense)

Setting the Power Mode switch to AUTO will allow the amplifier to monitor the level of signal coming in from the 
source connection and power on when the level is high enough to be process as an audio signal.  No further setup 
is needed.  

When a source attached to any input generates a signal, the amplifier will power on, and will remain on as long 
as the signal is maintained.  After 20 minutes of inactivity on all inputs, the amplifier will power down and return to 
Stand-by mode until a signal is received again.

6.4.4. 12 Volt Trigger

Some audio sources and custom remote control systems can use a 12V DC trigger output to control the power 
state of an amplifier.  The EA-AMP-12D-45A equipped with 12V DC trigger inputs and outputs to allow for trigger 
control and daisy chaining for control of more than one amplifier.

To utilize the 12V DC trigger function, set the Power Mode switch to the right (closest to the 12V trigger 
connections) and attach a mono mini cable between the 12V trigger output of the controlling device and the 
TRIGGER DC 12V IN port on the EA-AMP-12D-45A.  Connect to other devices by connecting them to the OUT 
port on the amplifier with a mono-mini cable.
