This turns the main power to the MPS-1 on or off. It is a main power button, but it is not required to turn this on and off each time the MPS-1 is used. When enabled, the AUTO ON/OFF MODE will automatically switch the amplifier on when an audio signal comes from a source or control unit (such as a preamplifier). The TRIGGER MODE will turn the amplifier on when an external source (such as a preamplifier) provides a 5-24 VDC input on the trigger terminals.

2Panel Dim Selector Button

This button selects the overall brightness of the lighting on the front panel of the MPS-1. The button has four steps, each consecutively after the other. The four levels of brightness are:

•High

•Medium

•Low

•OFF

Pressing the PANEL DIM button repeatedly will scroll through each level of bright- ness.

This multi-color LED display behind a tinted acrylic panel shows activity of any of the seven power modules on the MPS-1 doing amplification duties.

BLUE LIGHT: Power Module is installed, on and ready.

AMBER LIGHT (middle row): Power mod- ule is installed and powered on but is in a standby situation waiting for audio signal or exernal trigger.

See the“Troubleshooting Section”for more details on the display.

Note - When there is NO LIGHT - The power module is not installed, the power module’s fuse is blown, or connection between the power module and the chassis is mis- aligned.
