Dayton Audio MA1280 12-Channel Class D Installation Amplifier

The Dayton Audio MA1280 delivers 12 channels of efficient Class D amplification—ideal for powering up to 6 stereo zones in custom installations. Each channel delivers 80W into 8 ohms or 160W into 4 ohms, with bridging capability for higher output (160W @ 8 ohms). This allows flexible deployment across a variety of speaker setups, including in-wall and ceiling speakers.

Input options include 12 dedicated RCA inputs and two global stereo bus inputs (Bus A & B), with selectable input routing per channel. The unit supports both manual and automated control via auto-on signal sensing and 12V triggers for each zone, plus 12V trigger outputs for system-wide coordination. Independent gain controls per channel enable precise level balancing across zones, while built-in overload, short circuit, and thermal protection ensure long-term reliability.

The MA1280 is housed in a 2U rack-mountable chassis with Phoenix-style speaker connectors, designed to integrate cleanly into residential or commercial audio racks. Whether you’re installing a full-house audio system or a multi-zone commercial setup, the MA1280 delivers dependable, flexible, and powerful amplification where it counts.
