FRONT PANEL CONTROLS These blue LED's indicate that AC power is connected and the amplifier is turned on. 1. Rack Ears These ears are used to mount the amplifier in any standard 19” rack. 7. Protect Indicators These red LED's indicate that the channel is in Protect mode. When the channel goes into protect mode all output for that channel will be muted. The protect LED's light when overheating or other severe problems occur. This is to protect any speakers connected to the channel.
REAR PANEL CONTROLS 7. 5-way Binding Post Connect each channel of the unit to your speakers. Binding posts are provided for each channel as well as Speakon® connectors, so that paralleling of speakers is possible. Connection to the binding posts can be made with bare wire, banana plugs, or spade lug terminations. Make connections to both the Channel 1 and Channel 2 terminals for Stereo or Parallel Mode, or a single connection across the red terminals only of Channel 1 and Channel 2 for Bridged Mono Mode.

When the protection LED turns on, this circuitry is active, and all connected speakers are muted. Initial power-up : For approximately five seconds after initial power-up, the protection circuitry is activated and the speaker outputs are muted.
