It is the latest version of Audison's SR 1.500 line, which dates back to 1988, rebuilt with ADT (Audison D-Class Technology) in a compact extruded-aluminium chassis with rounded corners. Built-in USS technology and Speaker-In inputs make it easy to connect behind a factory head unit.\u003c\/p\u003e\r\n\r\n\u003ch4\u003eKey Features\u003c\/h4\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eMono output: 500W @ 4Ω \/ 800W @ 2Ω \/ 1000W @ 1Ω\u003c\/li\u003e\r\n\u003cli\u003e1Ω-stable output stage for flexible subwoofer wiring\u003c\/li\u003e\r\n\u003cli\u003eVariable 24 dB\/octave low-pass filter and a switchable 25 Hz subsonic filter (24 dB\/octave)\u003c\/li\u003e\r\n\u003cli\u003eVariable bass boost (0–12 dB at 50 Hz) and 0–180° phase control\u003c\/li\u003e\r\n\u003cli\u003eBuilt-in USS (Universal Speakers Simulator) for head units with speaker load detection\u003c\/li\u003e\r\n\u003cli\u003eSpeaker-In inputs that recreate a pre-out signal from amplified OEM outputs, plus ART automatic turn-on\/off\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch4\u003ePower and Technical Highlights\u003c\/h4\u003e\r\n\u003cp\u003eBandwidth is 10 Hz – 500 Hz (-3 dB), stage distortion is 0.1% and the signal-to-noise ratio is 100 dBA.
