The HD4000 is a Class H amplifier with 4000 W @ Bridge 4Ω power output in a 19’’/2U format, ideal for use in fixed installations. HD4000 incorporates the soft-start circuit with gradual volume increase, clip limiters and special protection features such as temperature control, overcurrent, DC output and anti-short circuit on the outputs.
The whole HD series is based on our proven High Dynamic Power technology, which means higher efficiency in the ratio of power output versus energy consumed.

(1) Continuous burst tone 20 ms (0 dB) / 480 ms (-20 dB) in accordance with EIA RS-490 and IEC 60268-3(IHF A-202).
(2) Specifically designed for long term operation in bridge 4 Ω at full power.
(3) Driving the amplifier at 2 Ω channel / 4 Ω bridge at full power mode in poor ventilation conditions may cause a thermal overload protection. 2 Ω power is time limited by mains circuit breaker.
