Power amplifier Audac PMQ240 WaveDynamics™ quad-channel 100V

The Audac PMQ240 WaveDynamics™ quad-channel 100V power amplifier provides four independent 100V outputs for public address and distributed audio systems. Designed for installations that require constant-voltage audio distribution, this amplifier integrates WaveDynamics™ processing to manage level control and channel protection while maintaining clear audio performance across multiple zones. Its compact multi-channel format allows centralized amplification for paging, background music, and commercial audio applications where reliable 100V line outputs are needed.

Advantages

The amplifier offers four separate channels with dedicated WaveDynamics™ processing to ensure consistent level management and protection per channel. Built for 100V constant-voltage systems, it simplifies wiring and speaker deployment in large or multi-zone venues. The device’s channel independence enables flexible zone control and reduces the need for multiple amplifiers, supporting efficient installation and maintenance. Its design emphasizes stable operation and predictable behaviour under varying load conditions common in public address and distributed audio setups.

Suitable for

• Multi-zone public address systems in schools, offices, and retail spaces
• Background music distribution in restaurants, hotels, and shopping centres
• Paging and voice evacuation systems requiring 100V outputs
• Commercial installations with multiple speaker lines and centralised control

Key specifications

• Configuration: four independent amplifier channels
• Output type: 100V constant-voltage line outputs for each channel
• Processing: per-channel WaveDynamics™ level control and protection
• Application: designed for distributed audio, paging, and multi-zone music
• Form factor: rack-mountable compact multi-channel amplifier

How to use

Connect each speaker line to the corresponding 100V output for the intended zone, ensuring correct tap settings on line transformers or speakers to match required SPL and load. Use the WaveDynamics™ controls to set per-channel levels and engage protection features as needed to prevent overload and maintain consistent loudness between zones. Integrate the unit into the central audio system using typical PA wiring practices and provide adequate cooling and ventilation in the equipment rack.

Usage recommendations

Match speaker transformer taps to the amplifier channel output to balance volume across zones, and verify channel protection settings during initial setup. For reliable long-term operation, install the amplifier in a ventilated rack space and perform periodic checks on connections and level settings.
