Bogen's Black Max amplifiers are designed to provide maximum performance in constant voltage speaker sys-
tems. Dual 70V transformerless outputs deliver exceptionally clean audio to speaker systems requiring up to
1200 watts of total power, or two separate channels of audio up to 600W per zone, in a single package. High
efficiency class H amplifier design and auto-sleep feature reduce power consumption on continuously-powered
systems. Rear-mounted volume controls, independent low-cut filters on each input, and pluggable input termi-
nal strips were specifically designed for the fixed install market. Built-in power sequencing for controlling mul-
tiple Black Max amplifiers combats current in-rush problems of large audio systems. Massive power toroid and
heat sinks; heavy 14-gauge chassis; Back-Slope™ AC voltage stabilization; clip limiters; and DC voltage, over-cur-
rent, and thermal protection circuits make this a workhorse amplifier.
