Cloud 46-50 - 4 x 50 watt, four zone low impedance, integrated mixer amplifier

The 46/50 offers simple, direct connection of two microphones and six music sources which can be routed to feed four different output zones with up to 50W of clean audio power. The 46/50's music programme and level can be controlled remotely. A paging facility is avilable with the optional CDPM paging mic.

If you need a simple yet versatile public address amplifier for both background music and paging in a four zone venue, the Cloud 46-50 amplifier is ideal.

An optional transformer module is availabel to convert the 46/50 to 70V or 100 volt line for distributed sound systems.
