Bogen Communications X450

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, 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.
