AMPLIFIER POWER CONTROL
Front Panel Power Button
When the amplifier is powered ON, the power swoosh will illuminate solid blue. When it is in STAND-BY,
the power button will be red.
Resetting the Amplifier
Press and hold the power button for 10 seconds once the receiver is powered on for a “soft” reset. This
will reset login information.
Press and hold for 20 seconds to initiate a factory reset. The front panel lights will flash indicating the
reset is in progress. This will reset all settings including DSP, channel levels and input names.
12 Volt Trigger
The EA-AMP-HYB line of amplifiers are equipped with 12V DC trigger inputs and outputs for trigger control
and daisy chain control of more than one amplifier.
To utilize the 12V DC trigger function, attach a mono mini cable between the 12V trigger output of the
controlling device and the 12V DC TRIGGER IN port of the amplifier. Connect other devices to the OUT port
on the amplifier using a mono-mini cable.
Audio Sense
If Audio Sense is enabled via setup through the web GUI, the amplifier will turn on when an audio signal
is detected. The unit will enter standby mode if no signal is detected after 15 minutes.
VOLUME CALIBRATION
To calibrate source input gain and inline volume control level:
1.
Connect all speaker and audio source wiring. Connect power to the amplifier.
2.
(If applicable) Set all volume controls to their maximum volume setting.
3.
Set each output level adjustment knob to 50% and set the input level for unused channels to minimum.
4.
Power on the amplifier and the source to be used. Play audio typical of what will be played in the
area. Set the source volume level to half. If the audio becomes distorted, turn the volume down until
audio is clear.
5.
Set the level adjustment for the area to a level where the volume is slightly above normal listening
level. If the audio becomes distorted, experiment with changes to the source volume and the LEVEL
adjustment knob until audio is clear.
Calibration Setup Tips
Poor Calibration may cause the following issues. Use the tips below to identify and correct these problems:
TROUBLESHOOTING
Distorted Audio at Normal Volume
If the LEVEL adjustment for a zone is set too high to compensate for low source volume, distortion can
occur in the form of background noise or poor audio quality. This will be heard as a steady hissing or
humming behind music, clipping of signal, or distortion of highs and lows.
To eliminate this issue, re-adjust the volume levels by starting at baseline settings and re-adjusting the
final volume so that a maximum comfortable volume level can be reached with no distortion while using
the source volume or inline control.
