Description

The Cloud MPA240MK2 is world-class premium 240W integrated Mixer Amplifier which provides a complete audio solution for Houses of Worship, retail outlets, hotels, licensed premises and other spaces where music, announcements and/or flexible paging are required. It combines the functions of a two-channel microphone mixer with full paging facilities, a six-input music source selector and a mono power amplifier in a single compact 1U unit.

The acoustic performance and best in class reliability makes this latest Cloud product another outstanding example of British design engineering by the world’s best manufacturer of BGM Electronics.
