46-80 4-Zone Mixer Amp 6-Line/2-Mic/ RS232 4x80W 4ohm 2U
Description
46-80 4 Zone Integrated Mixer Amplifier
The Cloud 46-80 is a versatile, four-zone, rack-mounting (2U) audio mixing amplifier. It combines simple control of background music, microphone paging and power amplification for up to four zones in a single unit. It has extensive remote control facilities and is ideal for installation in premises such as pubs, bars, hotels, clubs, leisure and fitness centres, retail and other commercial premises, etc.
The 46-80 has four mono zone outputs, each driven by an 80 W (nominal rating) power amplifier stage: if less than four separate zones are required, the power stages may be paralleled by moving internal jumpers to permit dual stereo, quad mono or stereo + dual mono operation, with accordingly increased output power. The power stages have extensive protection circuitry to safeguard both the amplifier and loudspeakers.
