DP 1,500 by Hertz
DP 1.500 is a 1-Channel Amplifier from Hertz featuring Advanced Class-D technology. The compact design includes a status LED, a removable top plate, and a solid machined terminal block. A balanced input circuit as well as Pre-In and Speaker-In are available. Adjustable input levels, a low-pass filter from 50 - 250 Hz with 24 dB/Oct., and a subsonic filter at 25 Hz with 24 dB/Oct. are integrated. The phase is switchable between 0/180°, bass boost at 50 Hz is selectable from 0 - 9 dB, and the SUB Remote Volume Control HRC 02 adjusts from -20 - 6 dB. The minimum load impedance is 2 Ω, and the maximum output power is 590 W. Other specifications include an efficiency of 86%, a bandwidth of 10 Hz - 500 Hz, a signal-to-noise ratio of 99 dBA, and a damping factor of 180.
