Introduction
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. Located on the rear of the amplifier are the Level Controls, Low-Cut Filter Switch, and pluggable input terminal strip for each amplifier channel. These amplifiers are powerful (with total system power of 1200W, 900W and 600W with both channels driven), but they are also compact - using up only 2 rack spaces (3-1/2") in a standard 19" rack.
Reliability and Functionality
Driven by a conservatively-rated toroidal power transformer, these amplifiers are built for solid performance with low distortion and a high slew rate.The amplifiers require little maintenance and cleaning as internal electronic com- ponents are located outside of the forced air stream flow. Front-mounted fan filters provide easy removal and clean- ing.
Black Max amplifiers have a variety of electronic protection circuits including overcurrent, DC voltage, and thermal circuits. A special Clip/Limiting circuit continuously monitors the amount of distortion in the output signal and reduces input levels as the amplifier approaches clipping. Back-Slope™ AC Voltage Stabilization, Bogen’s unique volt- age stabilization circuitry, regulates the AC energy supplied from the power toroid.This improves both system per- formance and reliability despite varying AC supply conditions.
An energy-conserving sleep mode (defeatable) with instant-on return signal operation reduces wasted heat pro- duction in paging systems with intermittent use. In addition, large output heat sinks and dual independently-con- trolled, high-output, variable speed fans provide superior cooling and quiet operation while reducing dust accumu- lation.
A simple and reliable sequential turn-on feature minimizes in-rush current from the AC power mains.When multi- ple Black Max amplifiers are daisy-chained together for sequential turn-on, the first amplifier in the series will con- trol the powering up of the other amplifiers with approximately 1 second of delay between units. Turning off the first amplifier causes all amplifiers to turn off.
