Dayton Audio MA1240a 12 Channel Amplifier

The MA1240a includes a Class-AB output circuit that produces excellent sound quality and a stable performance across all six zones. Each of the twelve channels has its own dedicated input and independent level adjustment to provide further flexibility. Two channels can be bridged to increase the total power output for that zone by simply flipping a single switch. This is helpful when extra power is needed in certain areas. Two common or BUS inputs feed audio signals from standard line-level audio sources to any or all channels. The MA1240a's manual, automatic on/off, or triggered 12V input turn-on modes allow simple integration into automated systems. Each pair of channels or zones has a bi-colour LED to indicate its operational status. The MA1240a can be stacked with other audio components and includes removable ears for mounting in standard audio racks (2RU).
