24-120 2-Zone Mixer Amplifier

The Cloud 24-120 is a brand-new approach to 2 Zone Mixer Amplification. Utilising the highest quality amplifier and power supply digital technology. It combines simple control of background music source, music level and microphone paging for up to two zones in a single unit. It has extensive remote control facilities and is ideal for installation in premises such as pubs, bars, hotels, leisure and fitness centres, retail and other small commercial premises.

The 24-120 in includes two transformer-less Class-D 120W amplifiers with limiters on each zone plus Thermal/Short Protection, as well as 4 Line inputs (2x unbalanced/ 2x balanced). High-Impedance Power sharing means the 24-120 automatically allocates unused channel power with no configuration required (240W available).
