Bogen's Black Max amplifiers are designed to provide maximum performance in constant voltage speaker
systems. Dual 70V transformerless outputs deliver exceptionally clean, full bandwidth audio to speaker systems.
Up to 1200 watts of total output power on two separate channels of audio (up to 600W per channel/zone) are
available in a single unit. High efficiency class H amplifier design and auto-sleep feature reduce power
consumption on continuously-powered systems. Specifically designed for the fixed install market with features
like: rear-mounted volume controls, independent Low Cut filters, independent input sensitivity switches, input
channel link switch, and pluggable input screw terminals. Built-in power sequencing for controlling multiple Black
Max amplifiers combats AC 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-current,
and thermal protection circuits make this a true workhorse amplifier.
