Bogen's Black Max amplifiers are designed to provide maximum performance in constant voltage speaker systems. Dual 70V
transformerless outputs deliver exceptionally clean audio to speaker systems requiring two channels of audio up to 600W
per channel, in a single package. High-efficiency class H amplifier design and the auto-sleep feature aid in reducing power
consumption on continuously-powered systems. Rear-mounted volume controls, independent low cut filters on each input,
and pluggable input terminal strips were specifically designed for the fixed install market. Built-in power sequencing for multiple
Black Max amplifiers combats current in-rush problems of large audio systems. Massive power toroid and heat sinks;
heavy 14-gauge chassis; patented Back-Slope
™
AC voltage stabilization; clip limiters; and DC voltage, over-current,
and thermal protection circuits make the Black Max both an efficient and reliable workhorse amplifier.
