5.3Grounding

In some installations where the sound system is sensitive to RF noise or system-induced oscillation, it may be necessary to ground the amplifier's chassis to the rack enclosure. This is accomplished using star type lockwashers on the four rack mounting screws. These star washers will penetrate through the amplifier's paint to adequately ground the chassis to the rack.

6.FRONT PANEL FEATURES

6.1Power Switch

When the unit is switched on there is a 2 second delay, during which time the PROTECT circuit will acti- vate. The load is disconnected during this power-up se- quence . When turning off the amplifier, the load is re- moved instantly, and the protect LED will briefly turn on as the power supply discharges.

6.2Thermal Status Meters

This left-most green LED, when turned on, indi- cates normal thermal status. If either amplifier channel overheats, these lights will both turn off, indicating that power has been cut off from the audio portion of the am- plifier. The AC Power Switch will remain lit, and the cooling fan continues to operate until the amplifier is within safe operating temperatures again.
