Description

Designed for high quality signal amplification as part of professional sound systems. It consists of an input module, power amplifier modules, power supply, digital sound processor DSP, built into a metal case. The amplifier belongs to class D with active distortion compensation. Features are the absence of thermal distortion, which is especially noticeable in the reproduction of low frequencies, full control of the speaker cone due to the extremely low output impedance, no need to use Zobel circuits, as feedback is taken directly from the output, correcting distortion and nonlinearities that are introduced into the signal, the presence of a switching power supply with an active power factor correction (PFC), thanks to which the efficiency can reach 96%, the presence of an integrated circuit LLC, which allows you to use the power supply with an active power factor correction (PFC).
