1 - POWER AND STATUS AREA

1.1 - MAIN POWER SWITCH

Press the top of the rocker switch to engage the amplifer main electrical power. Press the bottom

of the rocker switch to disengage the power and turn the amplifier off. If using 12VDC or relay

trigger to control amp operation, this switch should be left in the ON position.

1.2 - AMPLIFIER STATUS INDICATORS

DSP ACTIVITY

- This LED will illuminate, solid or blinking, when communicating with the ampli-

fier via USB software control.

STANDBY/PROTECT

- This LED will illuminate when the amp has been put into standby condi-

tion, or when the amp has entered protection mode due to an operational fault.

POWER

- This LED will illuminate when the amplifier main power is on.

1.3 - FRONT PANEL DISPLAY BACKLIGHT DEFEAT

Use this switch to defeat (turn-off ) the amplifier front panel LCD display backlight. It is recom-

mended that once installation is complete, the front panel backlight be turned off with this

switch to conserve power and preserve backlight life. This will defeat the backlight itself, but not

the text displayed. STANDBY and PROTECT modes will still be indicated on the front panel via the

power LED.

1.4 - AC INLET

Main AC power inlet. Connect the mains power cable here.

CAUTION: CONNECT ONLY LINE VOLTAGE INDICATED ON SERIAL NUMBER LABEL. CON-

NECTING THE AMPLIFIER TO ANY OTHER AC VOLTAGE WILL RESULT IN AMPLIFIER DAMAGE.
