The DP 4.400 is a 4-Channel Amplifier from Hertz with High-Resolution Audio certification. The Class AB amplification is fully bridgeable and stable at 2 Ω, channels 4 - 3 - 2. The bandwidth at -3 dB ranges from 10 Hz to 45 kHz, the signal-to-noise ratio is 101 dBA, the damping factor is 130 at 1 kHz and 1 W, the distortion is 0.01% at 100 Hz and 70% rated power, and the efficiency is 60%. The power supply operates with 6.5 - 16.5 VDC, the nominal supply is 11 - 15 VDC via 2 x 25 A fuses, the idle current is 0.85 A, and the standby power consumption is 10 uA. There are preamplifier and speaker inputs available, a full-range preamplifier output for front, pre-in sensitivity of 0.32 - 8 VRMS, and speaker-in sensitivity of 1.6 - 40 VRMS. Adjustable crossovers with high-pass and low-pass Full/50 - 4000 Hz at 12 dB/octave for front and rear, as well as bass boost at 50 Hz from 0 - 9 dB, are integrated. ART Automatic remote control for turning SPK-IN on/off (only BTL radio) and minimum load impedances of 4 channels 2 Ω, 3 channels 2 Ω + 2 Ω + 4 Ω, and 2 channels 4 Ω are available.
