Description

The MA60 is an exciting development from Cloud Electronics, combining for the first time the proven versatility of Cloud mixer-amplifiers in a single compact (2U, half-rack width) unit, and at a very competitive price point.

The MA60 will find many applications in the Retail, Hospitality, Licensed Premises and other entertainment markets and is the most feature rich of the Utility Mixer/Amps on the market which also offers the best sound quality and the traditional Cloud reliability.

Single Zone, 60w, 4Ω Output as Standard with Optional 50w, 70/100v Internal Transformer (CXL-50T).
