Amplifier Front Panel

1.Mounting Holes – For rack mounting.

2.Power Switch – Switches the unit on or off. Note: The power switch can be disabled from Proteane Software

3.Status LEDs – Indicate status of: Power, Standby, Protect, Power Switch Disable, and Comm activity

4.Air Inflow Vents – Cool air enters here

5.Channel Controls – Channel control area

6.Signal LEDs – The lowest LED will begin to light when the output voltage reaches -18dBu below rated output. The Clip LEDs will begin to flash when output voltage is 1/2 volt below the output power supply voltage.

7.Bridge – This LED indicates that the channel pair is selected to BRIDGE mode from the back panel switch, and that only the odd input channel level control is active

8.Temp and Current LEDs – The Temp LED indicates that the amplifier has reached an excessively high operating temperature. The Current LED confirms that the amplifier output is delivered to a speaker load.

9.Channel Attenuators – These control the input signal level to the amp, and can be disabled from software.

10.Factory Reset – To reset all internal configurations (including passwords) back to their original factory set- tings, press and hold this recessed front panel tact switch during power up until all channel LEDs are lit. Upon reset completion, the LEDs will turn off and the amp will be in normal operating mode.
