Hertz SP 4.500 SPL Show Class D 4 Channel Amplifier
Ch: 4 - 3 - 2 | 600 W
SP 4.500 features Hertz ADC (Advanced D-Class) output stage, reaching up to 87% efficiency and delivering an impressive power rating of 90 x 4 (4Ω) W RMS or 300 W x 2 (4Ω) W RMS when bridged, with an ultra-compact size of 192.7 (7.58) x 130 (5.1) mm (in.) x 49 (1.9). Being ultra-compact with impressive power, SP 4.500 is the ideal choice for Motorcycle applications and for under-seat in sports cars and behind-seat installations in trucks.
Features:
- Up to 87% efficiency thanks to ADC (Advanced D-Class) output stage.
- USS (Universal Speakers Simulators) allows SP 4.500 to work with head units featuring the “speaker load detection” circuit.
- 90 W RMS x 4 (4Ω) with ultra-compact size: 192.7 x 130 x 49 / 7.59 x 5.12 x 1.93 (mm/inch)
- IP55 aluminum chassis for maximum protection against humidity and external agents.
- 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).
