VOID Acoustics BIAS Q1+ 4-Channel Power Amplifier with DSP

Product Overview

The VOID Acoustics BIAS Q1+ is a compact professional four-channel power amplifier with integrated DSP, designed for efficient and reliable amplification in professional sound reinforcement, commercial audio, distributed systems, and fixed installations. Delivering 300W per channel at 4 Ohms and 8 Ohms, the BIAS Q1+ provides flexible multi-channel amplification in a lightweight 1U rackmount format.

Supporting low-impedance loudspeaker loads from 2 Ohms as well as 70V and 100V distributed audio systems, the BIAS Q1+ can be used across a wide range of loudspeaker configurations. Its Smart Rails Management technology and power-factor-corrected power supply provide efficient operation while helping reduce energy consumption and heat output.

The integrated DSP provides advanced system-management tools including equalisation, crossover filtering, delay, gain, polarity, and sophisticated protection limiters. With ArmoníaPlus software monitoring and control, the BIAS Q1+ is ideal for professional installations requiring precise loudspeaker processing and dependable four-channel amplification.
