SR 4.300
1. ADC (Audison D-Class) Technology 2Ω stable output stage ensuring
high audio performance in a compact size.
2. Extruded aluminum compact design with fanless convection cooling
system.
3. Built-in USS (Universal Speakers Simulator).
4. Balanced high-noise rejection input speaker-In (for OEM head units)
and RCA-In (for After-market head units) inputs.
5. ART (Automatic Remote Turn-On/Off) automatically turns on/off the
amplier when the OEM head-unit turns on/off (can be enabled/
disabled, with Speaker-In inputs).
6. Pre-outs, also available when using Speaker-In level inputs.
7. Mono operation mode (selectable) to create a sub + front three-
channel system or a powerful two-channel system.
8. Bass Boost (50 Hz) adjustable to 12 dB, to increase the subwoofer
punch.
9. Lo-Pass and Hi-Pass 12 dB adjustable (50 Hz to 3200 Hz) lters,
providing the ability to build a front + rear system, a multichannel
woofer + tweeter system or a powerful sub + front system.
