Panel Descriptions
Black Max Rear Panel
1. High-Impedance Balanced Inputs
Pluggable
2. Input Level Controls
Continuously variable input level controls.
3. Lo-Cut Filters
Roll off frequencies below 60Hz (2nd order) to prevent saturation of speaker transformers. Flush switch actu- ators reduce tampering.
4.Automatic Sleep Mode
Allows the unit to automatically put itself into a sleep mode when there has been no input activity for more than 3 minutes. In sleep mode, the amplifier’s idle power is greatly reduced. The amplifier immediately and noiselessly returns to its
5. Power Sequencing Inputs
Multiple Black Max amplifiers can be wired together in a daisy chain to allow for controlled sequential power- up. A pluggable terminal strip is provided for easy installation.
6. Power Sequencing Switch
Turns power sequencing on or off so that an amplifier can be controlled by either its front circuit breaker switch or by another Black Max amplifier. Flush switch actuators reduce tampering.
7.AC Power Status Indicator
Indicates the AC power status of the Black Max amplifier.When the indicator is off, no AC power is applied to the line cord. When amber, power is applied to the line cord but no sequential trigger has been received to place the amplifier into a fully powered up state (or power switch is off).When green, the amplifier is fully pow- ered.
8. Ground Terminal
Provides convenient access to earth ground.
9. Speaker Terminals
Connects to 70V constant voltage speaker loads. One set for each amplifier section. Accepts up to #10 AWG wire or spade lugs for speaker system connections.
10. Fan Exhausts
Cooling air outlets for independent, variable speed cooling fans.
