PROEL HPD3400

The HPD3400PFC features an amplification section based on an improved version of Pulse Width Modulation technology. The innovative topology of the amplification circuit and the very high sampling rate ensure very high performance in the whole audio range, whereas new-generation semi-conductors and the innovative signal reconstruction filter guarantee excellent audio quality. The new power supply section provides full output power with any mains voltage (150 V to 264 V: 230 V model, 85 V to 132 V: 120 V model - 50/60 Hz) and include the PFC (Power Factor Correction), able to guarantee that the AC input current wave form is sinusoidal and in phase with the mains voltage wave form. Thanks to the high efficiency of the power section and to the new power supply section we've been able to keep the weight of these amplifiers low to facilitate transportation and set up. The protection system includes thermal protection, short circuit protection, high frequency protection and a CLIP LIMITER circuit. Several user configurations can be selected in the input section STEREO/BRIDGE/PARALLEL) as well as several filtering options (FLAT/BI-AMP/HPF).
