The new HP-D Series of amplifiers employ digital amplification modules based on an improved version of PWM technology. The innovative topology of the amplification circuit and the employment of a 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. Thanks to the high efficiency of the power section and to the switching power supplies, the weight of these amplifiers is very low. 2 and 4 channel versions of the HP-D models are available, with 500 W or 750 W power per channel, and the largest model reaches an impressive 3000 W overall power. 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).
