The Crest Audio 9001 is a high-power amplifier designed to meet the most stringent needs of professional use in concert touring, high quality sound reinforcement, and professional fixed installations.

The 9001 incorporates Crest Audio’s Power Density™ engineering design philosophy, providing users with more substantial power and increased headroom for a given size than comparable amplifiers.

A three rack-space amplifier, the 9001 uses forced-air to cool channel heat sinks mounted in a back-to-back tunnel configuration. Stereo, parallel, and bridged mono operating modes can be chosen with a rear-panel Mode Select switch. Actively balanced female XLR input connections and single-screw solderless output connectors are provided for each channel.
