The DCP1V4S from Yamaha facilitates remote operation of your MTX series matrix or MA2030 mixer amplifier. One volume control and four input source selector switches put a lot of control in a convenient single-gang wall mount panel, and a standard RJ45 connection simplifies installation.
Constant Voltage (70-Volt) Audio Systems
Audio distribution systems, especially those commonly used in department stores, warehouses, restaurants, etc., require that many loudspeakers be driven from a single audio amplifier over long runs of speaker wire. The "constant voltage" or "high impedance distribution" audio systems can be complex to understand at first, however, provides many advantages. Learn how to design your own 70-volt or 25-volt loudspeaker system.
