    Dayton Audio's MA1240a is a versatile, twelve channel class AB amplifier. The amplifier is specifically engineered for multi-zone applications, but the flexible in- /output interface make this amplifier fit for many more applications. Ranging from amplifying the different drivers of an active speaker system to delivering up to twelve channel amplification for home cinema applications.



    • Excellent Class-AB design for high sound quality and stable performance
    • Bus inputs along independent inputs for each channel
    • Bridgeable outputs allow extra power when needed
    • Each channel has independent gain controls
    • A pair of temperature controlled low noise cooling fans.
    • Low standby power consumption


    Product details

    Dayton Audio MA1240a Multi-Zone 12 Channel Amplifier


    The MA1240a is a renown multi-zone amplifier from our home audio amplifier category. It shares it’s appearance and functionality with the slightly more potent Dayton Audio MA1260, but the MA1240a relies on class-AB technology that provide lower distortion performance. The linear power supply, with two massive transformers and the Class-AB technology deliver stable performance along the excellent sound quality.


    The in- and output interface creates extended flexibility when it comes to source and speaker connections. Each zone uses two channels that can be switched for individual operation or for bridged operation, if more power is required. Each channel has access to three inputs; an individual input and two bus inputs. The bus inputs can provide a single signal to all channels at once. If you wish to connect multiple devices the trigger input, trigger output and two bus outputs come in handy!


    The enclosure comes with feet for free standing applications and (removable) ears for 19” audio rack applications.





    Q: Can I use this amp with an audio streamer like Sonos connect, Apple Airport or Chromecast?

    A: The MA1240a accepts line-level sources on the individual and bus inputs. You can even use multiple or different streamers for different zones. If you are interested in building your own (multi-zone) streamer, take a look at the products from Arylic.


    Q: Which input should I use for bridge operation?

    A: In bridge mode the amplifier will only use the left input.

    Product seems to be well manufactured and well working (but it's early to say!) Hope it will work for a lot of years (its precedent similar product - other brand - worked for more than 10 years!). Class AB amps are good amps, low noise - great sound!
