Hertz SP 4.900 SPL Show Class D 4 Channel Amplifier
Ch: 4 - 3 - 2 | 1000 W
SP 4.900 is the first Hertz amplifier featuring the renewed Hertz ADC (Advanced D-Class) output stage, reaching up to 85% efficiency and delivering an impressive power rating of 160 x 4 (4Ω) W RMS or 500 W x 2 (4Ω) W RMS when bridged, with an ultra-compact size of 211.6 (8.3) x 130 (5.1) mm (in.). Being ultra-compact with impressive power, SP 4.900 is the ideal choice for Motorcycle application 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 4.900 to work with head units featuring the “speaker load detection” circuit.
- 160 W RMS x 4 (4Ω) with ultra-compact size 211.6 x 130 x 49 / 8.3 x 5.1 x 1.9 (mm/inch).
- IP55 aluminium chassis for maximum protection against humidity and external agents.
- No cooling fan to prevent internal accumulation of dirt 6. Sealed power cord, line inputs, and speaker outputs to prevent oxidation.
- Crossovers filters and controls on a single side to facilitate calibration when the product is installed.
