Amplifiers
Models X600, X450,
and X300
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
1
200 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
1
4-gauge chassis; Back-Slope™ AC voltage stabilization; clip limiters; and DC voltage, over-cur-
rent, and thermal protection circuits make this a workhorse amplifier.
