Cloud MPA 240 General Purpose Mixer Amplifier, The increase in demand for higher quality mixed impedance output amplifiers for general installer applications has instigated the launch of Cloud Electronics new MPA Series. 6 line + 4 microphone inputs into a single zone with configurable 25/70 or 100volt internal transformer plus the industry standard wall mount remote controllers (RL1 & RSL6) make the MPA Series the most flexible and reliable installer amps in the market.
