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 secure- ly. Located on the rear of the amplifier are the Level Controls, Low-Cut Filter Switch, and pluggable input ter- minal 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 elec- tronic components are located outside of the forced air stream flow. Front-mounted fan filters provide easy removal and cleaning.
Black Max amplifiers have a variety of electronic protection circuits including overcurrent, DC voltage, and ther- mal 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 voltage stabilization circuitry, regulates the AC energy supplied from the power toroid. This improves both system performance and reliability despite varying AC supply conditions.
An energy-conserving sleep mode (defeatable) with instant-on return signal operation reduces wasted heat production in paging systems with intermittent use. In addition, large output heatsinks and dual independently- controlled, high-output, variable speed fans provide superior cooling and quiet operation while reducing dust accumulation.
A simple and reliable sequential turn-on feature minimizes in-rush current from the AC power mains. When multiple Black Max amplifiers are daisy-chained together for sequential turn-on, the first amplifier in the series will control 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.
