Reduce the output volume using the specific channel’s level controls until the clipping disappears or until the CLIP LEDs flash only occasionally.

7.PROTECT Indicators

These yellow LEDs indicate that the channel is in either PROTECT mode or MUTE mode. When the channel goes into protect mode its output will turn OFF. This is to protect the speakers connected to that channel.

NOTE: The protect LED will light when the heatsink is overheating. Once the affected channel’s heatsink cools down, the output signal will automatically resume and the PROTECT LED will turn OFF. Constant triggering of the thermal protection indicates blocked vents, dusty air filters, possible low load condition, or problems with your speakers or cables.

NOTE: The PROTECT LEDs will illuminate for about two to three seconds when the amplifier is powered ON and they will fade slowly when the amplifier is powered OFF. This indicates your amplifier is going through a transition process and the outputs are muted.

WARNING: If the PROTECT LEDs illuminate constantly and don’t turn OFF, even when the speakers are physically disconnected from

the amplifier’s outputs, this indicates a fault. Immediately turn the amplifier OFF, disconnect the power cord from the AC outlet, and refer the amplifier to service personnel. Authorized B-52 service centers are listed at www.B-52Pro.com

8.BRIDGE LED

This green LED illuminates when the MODE switch on the rear panel is set in the BRIDGE position. Use the Channel 1 LEVEL control to adjust the output volume in BRIDGE MONO mode; the Channel 2 LEVEL con- trol is inactive in this mode.

9.POWER LED

The blue LED will illuminate when your amplifier is turned ON.

10. PARALLEL LED

This green LED illumiates when the MODE switch on the rear panel is set to PARALLEL. Use the Channel 1 LEVEL control to adjust the output volume of Channel 1 and the Channel 2 LEVEL control to adjust the out- put volume of Channel 2, even though both channels amplify the same signal connected to the Channel 1 input.

11. AC Power Switch

Use this switch to turn your amplifier ON or OFF.
