The Bias Q3 is a four-channel touring amplifier engineered to deliver premium-grade power and absolute reliability in all environments. With up to 2300 W per channel on 4 Ω asymmetric loads, it stands out as the ideal choice for high-output full-range systems—even when working with high impedance (8–16 Ω)—ensuring powerful SPL performance.

It features an innovative regulated power supply, with active Power Factor Correction (PFC) and Smart Rails Management™ (SRM) for optimal energy efficiency. The intuitive 4.3" touchscreen with rotary encoder enables quick and easy control on site.

The Q3 includes top-tier DSP with fixed latency architecture, advanced IIR, FIR, and raised-cosine filters, and a full suite of limiters (Peak, RMS voltage/current, and TruePower™). Comprehensive connectivity includes analog, AES3, and Dante/AES67, along with conversion and forwarding, automatic backup switching, and full integration with ArmoníaPlus software.

With Active DampingControl™ speaker cable loss compensation and robust comprehensive protection circuitry, the Q3 delivers stable, secure performance for demanding applications such as festivals, live venues, and small to mid-scale touring.

Void Acoustics: Amplifier Firmware Upgrade

Highlights

Advanced integrated DSP

The Bias Q3 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.

4.3” touch screen display and rotary encoder for intuitive control

The Bias Q3 redefines the audio management experience with its built-in multitouch capacitive display, designed to offer an intuitive and powerful user interface. Combined with a push-button rotary encoder, it allows precise control of levels, delays, routing, presets, and snapshots directly from the front panel, without the need for external software. The display supports advanced features such as Quick Navigation between settings, Intelligent standby modes with brightness adjustment, Password lock for secure installations, Instant visual feedback via backlit LEDs. In professional environments, Bias Q3 integrates seamlessly with ArmoníaPlus, automatically disabling the display to avoid control conflicts.

Intelligent efficiency with SRM™ technology

The Bias Q1.5+ 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.
