MicAD MASTER
The MicAD MASTER can be used to control all functions of any MicAD version. Usually, it is powered from the controlled MicAD; it has no POWER switch. All functions work in the same way as on the MicAD except for the following additional functions: [8] LINE/MIC Potentiometer When a remote control channel is selected, the potentiometer settings of the Master will usually be different from the ones of the selected MicAD. Normally, audio levels are displayed. As soon as a potentiometer is slightly turned, the Master's display changes to indicate the difference between the potentiometer setting and the actual gain setting on the MicAD.

With reference to this indication, the corresponding potentiometer has to be turned (down for our example) until only the center LED is on. During this matching process the potentiometer does not change the gain. As soon as only the center LED is on, the display changes to indicate the signal level again, and the potentiometer position is matched to the gain setting. From now on, the potentiometer is active and controls the gain of the MicAD's corresponding input channel. [13] CTRL CH Key to select the remote control channel to be operated.

In the example above, 3 MicAD units are remotely controlled by a MicAD Master. The audio channels are numbered in succession: Unit no. 1 holds the audio channels no. 1...8, unit no. 2 holds the audio channels no. 9...16, and so on. If the gain of audio channel 18 has to be adjusted, select remote control channel no. 3 by pressing CTRL CH as many times as required until a �3� is displayed. Then, the potentiometer no. 2 adjusts the gain of audio channel no. 18.
