MC3™ Specifications

The Radial MC3 is a passive studio monitor switcher. As such, the audio circuit itself should not introduce any form of noise, distortion or shift. Looking at the specifications, you will note that the MC3 produces less than 0.0003% distortion at all frequencies and the response shift is less than 1dB at 20kHz. This minute shift can be attributed to the resistor value of the potentiometer. These outstanding test results clearly demonstrate a faithful pass-through of the audio signal from the recording system to the monitors.
