Cloud Electronics MPA120MK2

The Cloud Electronics MPA120MK2 120 watt mixer amplifier, one of our favourite products, offers mixed impedance outputs on 4 ohms as well as 70V and 100 volt line.

The MPA series amplifiers are available in 2 output variations - MPA120MK2: 120 watts, MPA240MK2: 240 watts.

The MPA mixer amplifiers have six unbalanced stereo line inputs for music sources, and two balanced microphone inputs. Each microphone input has its own rear panel sensitivity control and front panel gain control, and the selected music source is mixed with the summed mic signals before being fed to the power amplifier stage.

The selected music source is mixed with the summed mic signals before being fed to the power amplifier stage.

The power output stage is transformerless, and is capable of driving 70/100 V-line loudspeaker distribution systems directly. Rear panel DIP switches allow the output voltage and impedance to be selected, permitting the amplifier to be used to either drive low-impedance (4 or 8 ohm) loudspeakers or 70/100 V-line systems.

The Cloud PM1 single-zone paging microphone is compatible and the MPA120 can also be used for one of the zones on the Cloud PM4/8/12/16 multizone paging microphone. Alternatively, the Mic 1 input may be configured to suit most OEM paging systems; paging is activated by a short-to-ground access connection, and can have automatic priority over the other mic inputs.
