[. . . ] switching bass and with our DCA Series Digital Cinema Amplifiers. [. . . ] In addition to their superior performance, we've packed these amplifiers with useful features and every input/output connector you'll ever need. With PowerLight technology, DCA amplifiers take your soundtracks to a whole new level. Not only does it give your movies bigger bass and cleaner highs, PowerLight also cuts wasted heat and boosts reliability. PowerLight is a switching power supply that provides ample current to the audio power circuitry by charging the supply rails 230, 000 times a second through an ultra-low impedance circuit. 1 & 2 | clip limiter on/off | LF filter on/off | LF filter freq select -30 or 50 Hz inputs parallel or stereo; bridge mode 850 W 1500 W 2400 W < -108 dB 1. 5 Vrms 1. 3 Vrms 2-tier Class H 8 A* < 0. 02% 1100 W 2000 W 3000 W < -107 dB 1. 7 Vrms 1. 5 Vrms 2-tier Class H 12 A* < 0. 02% DCA3022 550 W 625 W 900 W 1050 W 1500 W Specifications DCA3422 700 W 800 W 1100 W 1250 W 1700 W 1400 W 2300 W 3400 W < -107 dB 1. 9 Vrms 1. 7 Vrms 2-tier Class H 12 A* < 0. 02% Stereo Mode (both channels driven) 8 / 20 Hz ­ 20 kHz / 0. 03% THD 8 / 1 kHz / 1% THD 4 / 20 Hz ­ 20 kHz / 0. 05% THD 4 / 1 kHz / 1% THD 2 / 1 kHz / 1% THD Bridge-Mono Mode 16 / FTC 20 Hz ­ 20 kHz / 0. 1% THD 8 / FTC 20 Hz ­ 20 kHz / 0. 1% THD 4 / EIA 1 kHz / 1% THD Signal to Noise (20 Hz ­ 20 kHz) Input Sensitivity at 8 Input Sensitivity at 4 Output Circuitry Power Requirements (1/8 pink noise at 4) Distortion (SMPTE-IM) Distortion (typical) 20 Hz ­ 20 kHz: 10 dB below rated power 1. 0 kHz and below: full rated power Frequency Response Damping factor (1 kHz and below) Input Impedance Input Clipping Cooling Connectors (each channel) Controls 200 W 215 W 325 W 375 W 600 W Continuous average output power per channel Indicators Amplifier Protection Load Protection Dimensions (HWD) Voltage Gain Weight - Net / Shipping Optional Accessories Power-On: Green LED | Parallel inputs: Yellow LED | Bridged: Yellow LED Clip/Prot: Red LED | Level -10 dB: Green LED | Level -20 dB: Green LED | Signal -35 dB: Green LED (1 per channel) Full short circuit, open circuit, thermal, ultrasonic, and RF protection.
