4-channel hybrid Class-D power amplifier low impedance/100V - HPA MSC-HPAHYBRID4C

The HPA HYBRID-4C is a 4-channel hybrid power amplifier with Class-D output stages, able to operate both at low impedance and on 100 V lines. At low impedance it delivers 4 x 400 W RMS into 8 ohms, 4 x 800 W RMS into 4 ohms and 4 x 1200 W RMS into 2.7 ohms. In 100 V mode it provides 4 x 200 W RMS, while mono bridged operation delivers 2 x 1500 W RMS into 8 ohms / 100 V and 2 x 2500 W RMS into 4 ohms. Stereo, parallel and bridge modes allow the power amplifier to match different configurations and installations requiring substantial output power.

The Pascal Audio L-PRO2S amplifier module differentiates this unit from classic Powersoft amplifiers. A damping factor greater than 350 supports precise loudspeaker control. Input sensitivity is 1 V, while input impedance is 20 kohms in balanced mode and 10 kohms in unbalanced mode, allowing connection to various audio sources. The signal-to-noise ratio is 119 dB, total harmonic distortion does not exceed 0.05% at 1 kHz, and the frequency response extends from 20 Hz to 20 kHz within ±0.5 dB.

XLR inputs and speakON + Euroblock outputs provide quick, secure installation. Electronic, thermal and electrical protection is integrated to maintain reliable operation during intensive use. Cooling is handled by efficient fans and start-up is gradual. The power supply accepts 100 - 240 V AC at 50/60 Hz. The dimensions are 482 x 88 x 408 mm and the net weight is 7 kg.
