The Cloud MPA240 240 watt mixer output offers mixed impedance outputs on 4 ohms as well as 25V, 70V and 100 volt line.

The MPA series amplifiers are available in 2 output variations - MPA120: 120 watts, MPA240: 240 watts.

The MPA mixer amplifiers have six unbalanced stereo line inputs for music sources, and four balanced microphone inputs. Each microphone input has its own rear panel sensitivity control and front panel gain control, allowing multiple mics to be mixed together.

Each line input has a rear panel sensitivity control; the required music source is selected by a front panel rotary switch and the volume is also adjusted on the front panel.

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

The Cloud PM1 single-zone paging microphone is compatible and the MPA240 can also be used on one of the zones supported by 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.

Mic inputs may be selected to have automatic priority over the selected music source, and additionally, one line input may be set to have priority over any other selected to facilitate connection of a digital sound store or similar device. A pre-announcement chime is also available.
