A 470-MULTIROOM BS ACOUSTIC amplifier

Four-channel matrix amplifier with the possibility of matrix selection of four input signal sources. The amplifier is suitable for restaurants, cafes, etc. Each of the four amplifiers has a rotary four-position switch at the input for selecting the desired input signal. The inputs are solved by four stereo cinch connectors. The sensitivity of each input is adjusted using a trimmer near it. The outputs are solved by push-button terminals. There are eight holes on the top cover, through which it is possible to set two-band frequency corrections of all four amplifiers separately using a special axis (accessory). In addition to the rotary input switches, the front panel has four potentiometers for regulating the output level of individual amplifier channels with limitation indications. Cooling is provided by a temperature-controlled fan with a low noise level, which turns on from 50°C. The amplifier has a short-circuit and thermal electronic fuse.

- Input sensitivity 500mV
