Description
The 24-240 is a brand new approach to 2 Zone Mixer Amplification. Utilising the highest quality amplifier and power supply digital technology. The Cloud 24 Series is a two zone mixer-amplifier intended to provide 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. Catering for up to four music sources, it provides independent source and level control of music in each zone with microphone mixing as required, with full paging facilities. Each zone includes a mono power amplifier and the unit occupies only 1U of rack height.
