Power LED — The LED is lit when the unit receives power.
Stereo/Dual Mono toggle switch — Allows the user to choose between stereo
output for stereo program speakers or dual mono output for mono ceiling speakers
Potentiometers — Three front panel potentiometers are used to optimize level, bass,
and treble settings.
Unplug the remote plug from the unit.
Turn the Level potentiometer fully counterclockwise to its minimum setting.
Set the volume of the audio source to its maximum level. No sound should come out.
Slowly increase the MPA 152 MD 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.
