VOID Acoustics BIAS Q1.5+ 4-Channel Power Amplifier with DSP
Product Overview
The VOID Acoustics BIAS Q1.5+ is a compact professional four-channel power amplifier with integrated DSP, designed for demanding sound reinforcement, commercial audio, and fixed-installation applications. Delivering 600W per channel at 4 Ohms, the BIAS Q1.5+ provides a strong combination of power, processing flexibility, and efficiency in a lightweight 1U rackmount chassis.
Supporting low-impedance loudspeaker loads from 2 Ohms as well as 70V and 100V distributed audio systems, the BIAS Q1.5+ can accommodate a wide variety of professional loudspeaker configurations. Its automatic power-sharing architecture allows available amplifier power to be efficiently distributed when channels are operating with asymmetrical loads.
The integrated DSP provides advanced system-management functions including equalisation, crossover filtering, delay, gain, polarity, and sophisticated protection limiters. With network control through Armonía Pro Audio Suite, the BIAS Q1.5+ is well suited to professional Void Acoustics installations requiring precise loudspeaker processing and reliable multi-channel amplification.
