Bogen's Black Max™ amplifiers deliver on what professional sound installers need most: Power and Reliability. Power With three different models (X600, X450, and X300), the Black Max series provides 2 independent channels of amplification at 600W, 450W, and 300W per channel into 70V constant voltage speaker loads safely and securely.
Under such conditions, a built-in Clip/Limiting circuit activates and reduces input signal levels to protect both amplifier and speaker loads. One for each channel. 4. Power Switch/Circuit Breaker - Magnetic circuit breaker controls AC power to the amplifier.
4. CH B Input Select Switch - Allows output Channel B to source its input signal from either "A BAL INPUT" or "B BAL INPUT". 5. Lo-Cut Filters - Roll off frequencies below 60 Hz (2nd order) to prevent saturation of speaker transformers. Flush switch actuators reduce tampering.
Installation Mechanical Components 1. Rack Ears - Prior to installing the amplifier into a 19" rack, you will need to attach the rack ears. Remove and save the 6 front most cover screws on each side panel of the amplifier. Position the rack ears as shown and attach using the 6 screws. 2.
Ventilation The Black Max amplifiers were designed to be placed on a table or rack-mounted. For rack-mounted applications, the amplifiers can be stacked one on top of the other for maximum use of the rack space available without any extra, empty rack spaces between them. An open air space of at least 4"...
The polarity of each set of speaker outputs (A & B) is indicated with a "+" and "-" sign. Use these indicators to ensure that the phasing of the speakers are correct.
Sequential Turn-On Operation Black Max amplifiers contain a sequential turn-on feature that is designed to turn on a bank of Black Max amplifiers, one at a time, in sequence with approximately 1 second between each amplifier. This type of sequencing of power is necessary in large systems where the in-rush current of all the system amplifiers turning on at once would over- load the AC mains supplying the system.
LIMIT - When illuminated, it indicates a condition in which the amplifier is limiting and automatically reducing signal level to reduce the overload con- dition. Limiting is a result of speaker load impedances that are too low or input signals that are too high, which drive the outputs beyond their opera- tional ranges.
Sleep Switch The Black Max amplifier includes a sleep mode feature that greatly reduces the power consumption of the amplifier after it has been idle (no audio activity) for more than 3 minutes. Any audio activity present at the input will power up the amplifier instantaneously and noiselessly, so that there is no loss of audio.
