High Power Multi-Channel Amplification The Bias Q2+ delivers substantial output across four independent channels: 1500W per channel @ 2Ω 1200W per channel @ 4Ω / 8Ω This provides a total system output capability of up to 4800W, making it ideal for large venues and high-output applications. In bridge mode, channel pairs can deliver: Up to 3000W @ 4Ω Up to 2400W @ 8Ω This flexibility enables both multi-zone distribution and high-power mono configurations within a single amplifier platform. Designed for 100V Line and Low Impedance Systems The Bias Q2+ supports both low impedance (from 2Ω) and high impedance (70V/100V line) speaker systems, allowing mixed configurations across channels. This enables: Distributed ceiling speaker systems High-output low impedance loudspeaker setups Hybrid system designs Seamless upgrades to existing installations This dual compatibility ensures maximum flexibility for professional installers. Integrated DSP for Advanced System Control The amplifier features a powerful onboard DSP engine, enabling full system optimisation without external processors. DSP capabilities include: EQ, crossover, and filtering Limiting and speaker protection Delay alignment and routing Preset optimisation for VOID loudspeakers DSP+D versions also support AES67 and Dante networking for advanced signal routing and system scalability. This ensures consistent performance, system protection, and simplified commissioning across complex installations. High Efficiency and Intelligent Power Management The Bias Q2+ incorporates a 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: Reduced power consumption Lower heat dissipation Improved efficiency under varying loads Lower operational costs This makes it particularly suitable for continuous-use commercial environments. Compact High-Power Design Despite its high output, the Bias Q2+ is housed in a compact 1U rack format, measuring just 44.5mm in height and weighing approximately 7kg. This allows: High power density within minimal rack space Easier installation and transport Efficient system design in space-constrained environments Seamless Control and Monitoring The Bias Q2+ supports full system control via professional software platforms, enabling: Real-time monitoring and diagnostics Remote configuration and tuning Centralised control across multiple amplifiers This is particularly valuable in large or networked AV systems requiring precision control. Built for High-Demand Applications The Bias Q2+ is engineered for a wide range of professional environments: Nightclubs and music venues Bars and hospitality environments Retail and commercial audio systems Corporate and conference spaces Houses of worship and theatres Large-scale live events Its combination of high output and DSP control makes it suitable for both background and high-impact audio applications.
