The VOID Acoustics Bias Q1.5+ is a high-performance 4-channel Class-D power amplifier with integrated DSP, engineered for professional commercial and live audio applications. Delivering up to 4 x 600W of output power, it offers an ideal balance between power density, efficiency, and system flexibility, making it a strong choice for multi-zone installations and medium-to-large sound systems.
Positioned between the Q1+ and Q2+ in the Bias amplifier range, the Q1.5+ provides increased output while maintaining a compact 1U form factor, enabling scalable system design without compromising rack space.
The Bias Q1.5+ delivers:
This provides a total system output capability of up to 2400W across four independent channels, making it suitable for both distributed and high-performance loudspeaker systems.
In bridge mode, channel pairs can deliver:
This flexibility enables the amplifier to support both multi-zone audio distribution and high-output mono applications.
The Bias Q1.5+ supports both low impedance (2Ω, 4Ω, 8Ω) and high impedance (70V/100V line) speaker systems, allowing it to be deployed across a wide range of installation types.
This enables:
This dual compatibility ensures maximum flexibility for installers working across multiple environments.
The Bias Q1.5+ includes a comprehensive onboard DSP engine, allowing full system optimisation without external processing hardware.
DSP functionality includes:
This enables precise system tuning and ensures consistent audio performance across all zones and speaker types.
The amplifier features a highly efficient, microprocessor-controlled power supply with Power Factor Correction (PFC), ensuring stable operation across a wide voltage range.
Combined with Smart Rails Management technology, this delivers:
This makes the Bias Q1.5+ particularly well suited to continuous-use commercial environments.
Despite its high output capability, the Bias Q1.5+ is housed in a compact 1U rack chassis, measuring approximately 44.5mm in height and weighing around 7kg.
This allows for:
Its compact footprint makes it ideal for both fixed installations and touring setups.
The Bias Q1.5+ supports full remote control and monitoring via professional control platforms, enabling:
This level of control is essential for complex AV systems and high-end installations.
The Bias Q1.5+ is engineered for a wide range of commercial and live audio environments:
Its combination of power, DSP control, and flexibility makes it suitable for both background and high-impact audio applications.
