The X450 Black Max Power Amplifier from Bogen is powered by 450W per channel at 70V. Black Max amplifiers are designed with high efficiency class H amplification. The auto-sleep feature makes this amp ideal for continuously powered systems. The X450 features rear mounted volume controls, low-cut filters on each input and pluggable input terminal strips designed for permanent installations. Integrated power sequencing for controlling multiple Black Max amps in large systems help prevent in-rush problems. These features are packed in to a 14-gauge heavy duty chassis that only occupies 2 rack spaces.
