Dayton Audio MA1240a Multi-Zone 12 Channel Amplifier

The Dayton Audio MA1240a includes a Class-AB output circuit that delivers superior audiophile sound quality and stable performance. Each and every of your installation’s zones can get pleasure from the MA1240a’s clean audio reproduction and exceptional functionality. The MA1240a may also be stacked with other audio components and includes removable ears for mounting in standard audio racks (2RU).
Two common or BUS inputs feed audio signals from standard line-level audio sources to all or any channels. Each and every of the twelve channels has its own dedicated input and independent level adjustment to supply further flexibility. By simply flipping a single switch, two channels may also be bridged to extend the overall power output for that zone. That is helpful when extra power is needed in certain areas.
The MA1240a’s manual, automatic on/off, or triggered 12V input turn-on modes facilitate easy integration into automated systems. For quick and easy troubleshooting of the system, Each and every pair of channels or zones has a bi-color LED to suggest its operational status.
