Hertz SP 1.900 SPL Show Class D Mono Amplifier

Ch: 1 | 1000 W
SP 1.900 mono amplifier features Hertz ADC (Advanced D-Class) output stage, reaching up to 87% efficiency. The maximum power of 1000 W is already available at 2 and remains stable even at 1. Being ultra-compact (211.6 x 130 x 49 / 8.3 x 5.1 x 1.9) with impressive power, SP 1.900 is the ideal choice for Motorcycle applications under-seat in sports cars and behind-seat installations in trucks.
Features:

1. Up to 87% efficiency thanks to ADC (Advanced D-Class) 1 stable output stage ensuring high audio performance in a compact size.
2. USS (Universal Speakers Simulators) allows SP 1.900 to work with head units featuring the speaker load detection circuit.
3. 1000 W RMS (1) with ultra-compact size 211.6 x 130 x 49 / 8.3 x 5.1 x 1.9 (mm/inch).
4. IP55 aluminum chassis for maximum protection against humidity and external agents.
5. There is no cooling fan to prevent internal accumulation of dirt.
6. Sealed power cord, line inputs, and speaker outputs to prevent oxidation.
7. Crossover filters and controls on a single side to facilitate calibration when the product is installed.
8. Balanced fully differential high-noise rejection inputs.
9. ART (Automatic Remote Turn-On/Off) automatically turns on/off the amplifier when the OEM head-unit turns on/off (can be enabled/disabled).
10. 24 dB continuous adjustable (50 to 250 Hz) Lo-Pass subwoofer filter.
11. SUBSONIC filter (24 dB 25 Hz), removes very low subsonic frequencies from music signals to avoid damage to the subwoofer.
12. The optional HRC BM Remote Volume Control provides the ability to adjust the subwoofer volume level from the dashboard.
