Bias Q2 4-channel amplifier in a 1 RU format is designed to deliver reliable audio performance, energy efficiency, and installation flexibility, all within a lightweight and compact chassis. With a power output of 1500 W per channel at 2 Ω (up to 3000 W bridged at 4 Ω), it is ideal for fixed or mobile applications that demand high power density in a small footprint. The high-efficiency power supply, controlled by a microprocessor and featuring Power Factor Correction (PFC), ensures stable operation across any mains voltage from 85 to 275 VAC, with peak tolerance up to 400 V. The SRM (Smart Rails Management) technology dynamically optimizes internal voltage delivery, resulting in lower power consumption, reduced heat dissipation, and optimal management under variable loads. The amplifier is compatible with both Lo-Z systems (from 2 Ω) and 70V/100V distributed lines, including mixed configurations. DSP+ versions integrate digital signal processing and AES67 audio networking, allowing flexible routing, advanced EQ, FIR filters, limiters, delays, and polarity management via dedicated software. Compact, powerful, and ready for seamless AV integration, this unit is a perfect solution for clubs, hotels, retail environments, hospitality venues, and public spaces. Collapse text

Void Acoustics: Amplifier Firmware Upgrade

Highlights

Advanced integrated DSP

The Bias Q2 integrates an advanced hardware DSP designed to provide precise, secure and fully customizable audio management. 
The DSP+ version expands functionality with native support for the AES67 standard, enabling audio routing over IP networks and integration into complex digital systems. Everything is manageable in real time via ArmoníaPlus, for complete control over filters, limiters, signal and diagnostics, even remotely.

Versatile Application, Consistent Performance

Designed to work with lo-Z (from 2 Ω) and 70V/100V distributed lines, any mixed configuration of low and high impedance output loads is possible, making the Bias Q2 suitable for all applications in installed sound reinforcement systems.

Intelligent efficiency with SRM™ technology

The Bias Q2 incorporates Smart Rails Management™ technology, which adapts power draw in real time based on the load and audio signal. The result? Reduced power consumption, lower thermal dissipation, and maximum operating efficiency, even with UPS or limited power lines.

PFC (Power Factor Correction) for flawless worldwide operation

Highly efficient, microprocessor-controlled power supply with built in PFC (Power Factor Correction) for flawless worldwide operation with any AC mains voltage in the range 85-275 VAC tolerant to peak up to 400 V

    Intelligent variable speed ventilation

    Ventilation is controlled by internal temperature, with front-to-rear airflow for rack mounting.
