VOIBIASQ2P - Void Acoustics Bias Q2 and 4 Channel Power Amp with DSP 100V 4x1200W @ 4ohm AES67 1U Image 1

4800W/4-channel Flexible Amplifier with DSP and AES67. 4 x 1200 W at 8Ω

Bias Q2+ offers the amazing sound quality and reliability you would expect from all Void products. Offering a full suite of DSP tools via ArmoníaPlus control software. Delay, E.Q, Input trim, Gain and Polarity, Void speaker presets with FIR filters and Limiters.

The patented SRM (Smart Rails Management) technology allows to maximize the efficiency of the system and drastically reduces power consumption in any load and usage condition. Bias amplifiers feature extremely low thermal dissipation, reducing the need for external cooling devices.

Bias Q2+ is designed to operate with Lo-Z (from 2 Ω) and 70V/100V distributed lines or any mix of the two. DSP+ versions extend signal routing capabilities with the integration of AES67 digital audio networking architecture.

The amplifier platform that can be trusted in mission-critical applications, such as fire alarm systems, thanks to the cleverly engineered power supply that allows reliable operation even when connected to a UPS. Install amplifier featuring standard Phoenix connectors.
