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.
Absolutely! The MA1280 accepts line signals on both the bus and individual inputs, allowing you to connect different or multiple streamers to various zones. For DIY enthusiasts interested in building their own multi-zone streamer, check out our Arylic products range.
When configured for bridged output, the amplifier will use only the left input channel. This ensures optimal performance and easy setup for bridged audio applications.
The MA1280 does not come with a remote, however, it does have a trigger input so that other devices can turn it on.
Yes, the MA1280 accepts line-in on each input which also signals the auto-on feature.
