Product description The 46-120T from Cloud USA is a four-zone integrated mixer and amplifier well suited for supermarkets, retail stores, restaurants, bars, and other retail or industrial applications. The unit provides with individual source selection and volume control of up to six audio sources and two microphone inputs across four zones. Each zone provides 120W (4 Ohm) output or 120W (70/100V) output with the internal transformer modules pre-installed.
Each zone offers music level and source selection knobs, as well as level knobs for the two microphone inputs. Additionally, there are LF and HF controls for each zone, allowing for a customized sound for each zone. There are several options for remote source selection, volume control, and paging systems making the system a feature-packed single-box solution. The 46-120T ships with a power cord, a set of mating connectors for all real panel multi-pin screw-terminals, a set of four plastic feet, and a front panel security cover with mounting hardware. -
