Core Specifications & Design
• Power Output: Delivers a continuous 60 watts per channel into 8 ohms with all 12 channels driven simultaneously.
• Low-Impedance & Bridging: The amplifier features high-current capability and handles low-impedance speaker loads down to 2 ohms easily. Pairs of channels can be bridged to increase output dramatically for power-hungry zones.
• Class H Topology: Built using an efficient Class H design, which scales power rails dynamically based on the audio signal to keep the unit running cooler and drawing less unnecessary power.
Signal Routing & Integration
• Flexible Bussing System: Includes master audio bus inputs along with local inputs for each zone. Built-in sliding toggle switches on the back panel allow installers to easily assign which source bus each zone listens to.
• Local Auto-Sensing Overrides: Local zone inputs can be set to automatically override the main background bus audio whenever a specific source (like a local TV or streaming dock) turns on.
• Zone Triggering: Features independent 12-volt local triggers for each zone pair, allowing automation control systems to wake up specific rooms only when needed.
Built-in Speaker Protection
• LightDrive Anti-Clipping: Equipped with AudioControl’s signature LightDrive protection circuit, safeguarding connected speakers from damage, harshness, and distortion during high-volume playback.
• Subsonic Filters: Integrates custom bass-blocking filters designed to prevent low-end subsonic frequencies from over-excursing and muddying up the sound of standard architectural in-wall or in-ceiling speakers.
