Features

The MDA-100 mixing and distribution amplifier contains an 8x1-summing amplifier (mixer) and a 1 x 8 distribution amplifier in a case that is one rack unit high. The MDA-100 is useful, for example, in camera control (CCU), where multiple camera operators have to talk and listen to one master control location. In this application, audio from each camera (up to eight) is fed to one of the summing amplifier inputs of the MDA-100.

A trimmer on the front panel of the MDA-100 may individually adjust the gain of each summing amplifier input. There is also an output adjustment trimmer located inside the MDA-100 to adjust the final output level of the summing amplifier. The summing amplifier output is a 60Ω voltage sources. The input impedance may be set for bridging (20 kΩ, 150 Ω, or 600 Ω, selected by rear panel jumpers.

The MDA-100 fits into a standard 19” (483 mm) equipment rack. The power entry module is an IEC approved type, which contains a line voltage switch, a line filter, a fuse holder, and a line cord socket connector. The line voltage switch may be set for either 105/125 Vac, 50/60 Hz, or 210/250 Vac, 50/60 Hz supply voltages. The MDA-100 features a torroidal-transformer power supply for low-noise operation.
