Features
- Up to 87% efficiency thanks to ADC (Advanced D-Class) 1Ω stable output stage ensuring high audio performance in a compact size.
- USS (Universal Speakers Simulators) allows SP 1.900 to work with head units featuring the “speaker load detection” circuit.
- 1000 W RMS (1Ω) with ultra-compact size 211.6 x 130 x 49 / 8.3 x 5.1 x 1.9 (mm/inch).
- IP55 aluminum chassis for maximum protection against humidity and external agents.
- There is no cooling fan to prevent internal accumulation of dirt.
- Sealed power cord, line inputs, and speaker outputs to prevent oxidation.
- Crossover filters and controls on a single side to facilitate calibration when the product is installed.
- Balanced fully differential high-noise rejection inputs.
- ART (Automatic Remote Turn-On/Off) automatically turns on/off the amplifier when the OEM head-unit turns on/off (can be enabled/disabled).
- 24 dB continuous adjustable (50 to 250 Hz) Lo-Pass subwoofer filter.
- SUBSONIC filter (24 dB – 25 Hz), removes very low subsonic frequencies from music signals to avoid damage to the subwoofer.
- The optional HRC BM Remote Volume Control provides the ability to adjust the subwoofer volume level from the dashboard.
