DCA 3422

2-Channel Power Amplifier

FEATURES

  • Active Inrush Limiting - won't blow circuit breakers at turn-on
  • Both speaker and monitor panel outputs
  • Exclusive PowerLight power supply for great bass
  • A hum-free noise floor and ultra-low distortion
  • Only 3.5 inches high; even the most powerful systems can be built with only one rack
  • DataPort interface for DCP Digital Cinema Processors and DCM Digital Cinema Monitors
  • Patented Output Averaging™ short circuit protection
  • 14-inch deep - works with standard depth racks for lower cost and less floor space
  • Only 21 pounds, for easier racking and shipping - no need to remove amps from pre-wired systems before shipping
  • Gain control security cover protects amp against tampering and misadjustment
  • Variable-speed fan cooling and back-to-front air flow
  • Neutrik Speakon® and safety-shrouded barrier strip output connectors
  • LED indicators for metering, status, and operating mode
