Powersport HMP 1D by Hertz
The Hertz Powersport HMP 1D is a 1-Channel Amplifier with an aluminum die-cast housing and IPX64 rating. The compact format measures a maximum of 223 x 100.5 x 43.6 mm at 1.35 kg. It features a Crossover with a bridgeable crossover system, a low-pass filter at 65, 85, or 115 Hz at 12 dB/oct., a subsonic filter at 45 Hz (Off, 22 or 32 Hz, 12 dB/oct.), and a boost at 50 Hz (Off, +6 or +9 dB). It has balanced inputs with high suppression of electromagnetic interference and PRE IN. The bandwidth is 10–500 Hz, the signal-to-noise ratio is 105 dB, and the damping factor is 300 (100 Hz @ 4 Ohm). The distortion is 0.1% (100 Hz @ 4 Ohm), with Pre-In sensitivity LO: 0.2–5 V and HI: 0.8–20 V. Power supply is 11–15 VDC with 1 x 15 A Fuse, idle current is 1 A/0.04 mA, remote input is 4–15 VDC (1 mA), and it features automatic remote on/off. The HRC BM remote control for level adjustment is included.
