Commanding 12-Channel 6-Zone Architectural Distribution
Designed to power up to six stereo rooms or outdoor living zones from a single chassis, the MX1280 Gen 2 provides 80W RMS per channel at 4 ohms with vanishingly low distortion, eliminating the clutter of multiple separate stereo amplifiers.
Independent Channel Gain Calibration & Zone Power Toggles
Fine-tune output levels for each room using recessed rear-panel gain trim pots, ensuring balanced volume levels across varying room sizes and speaker efficiencies. Front-panel zone on/off switches provide instant tactile control over active zones.
Bridgeable High-Headroom Power for Outdoor & Large Spaces
Bridge any adjacent channel pair to deliver 160W of high-current power into 8-ohm loads, providing the dynamic authority needed to drive large landscape rock speakers, patio arrays, or in-wall subwoofers with ease.
Comprehensive Bus Matrix & 12V Automation Integration
Two shared global bus inputs with buffered loop outputs make it easy to daisy-chain additional amplifiers or broadcast a primary music source throughout the entire property, while 12V trigger in/out synchronizes with automation systems.
