Audison SR 6.600 Amplifier | 1120 W total power | 140 W x 4 + 185 x 2 @2ohm | D-Class

• High-current capability delivers high power into the most difficult loads (1Ω Stereo, 2Ω Bridged, for 5/6)
• Staggered power optimized for a 3-way active front with higher power for woofers, or 600W of bridged power for a sub 5 ch output operation mode to create a five-channel system, with 2Ω subwoofer
• Flexible crossover filter networks deliver Active 3-way, Front/Rear/Sub, or six channels of high-passed power
• ADT (Audison D-Class) Technology 2Ω stable output providing Hi-Res certified audio performance with superior efficiency in a compact size.
• Extruded aluminum compact design with a fanless convection cooling system
• Built-in USS (Universal Speakers Simulator)
• Balanced high-noise rejection inputs for Speaker-In (for OEM head units) and RCA-In (for Aftermarket head units).
• ART (Automatic Remote Turn-On/Off) automatically turns on/off the amplifier when the OEM head-unit turns on/off (can be enabled/disabled, with Speaker-In inputs)
• Accepts up to 40-volt input signal (Speaker-In)
• Bass Boost(50 Hz) adjustable up to 12 dB, to increase the subwoofer punch
• Lo-Pass and Hi-Pass 12 dB adjustable (50 Hz to 5000 Hz) filters, providing the ability to build a 3-way system, a front 2-way + rear system, or a front 2-way + one powerful subwoofer (2Ω)
• Optional VCR-S2/ARC 01 Remote Volume Control provides the ability to adjust the OUT 5/6
• volume level from the dashboard
