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 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 terminal strips were specifically designed for the fixed install market. Built-in power sequencing for controlling multiple 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-current, and thermal protection circuits make this a workhorse amplifier. *Dual 70V amplifier channels. *300W, 450W, or 600W per channel for 70V speaker systems. *Transformerless direct drive outputs. *Electronically balanced high-impedance inputs. *Built-in power sequencing of other Black Max amps.
