Power LED — The LED lights green when the MPA 152 unit is receiving power and

active. It lights amber when the unit is on standby (after 25 minutes of inactivity).

Stereo or Dual Mono toggle switch — Allows the user to choose between stereo

output for stereo applications (default) or dual mono output for mono applications.

Potentiometers — Three front panel potentiometers are used to optimize input level,

bass, and treble settings.

Setting Input Level

Adjust the MPA 152 input level as follows:

1. Unplug the remote plug from the unit.

2. Turn the Level potentiometer fully counterclockwise to its minimum setting.

3. Set the volume of the audio source to its maximum level. No sound should come out.

4. Slowly increase the MPA 152 level until sound distortion starts to occur. Lower the level

slightly until the distortion disappears. This setting will ensure that, whatever the volume

setting of the audio source, no clipping will occur.
