DM-RTA: How to connect AudioControl calibration microphones

When you connect the CM-10, CM-20, or C550H calibration microphones to the XLR connector on the DM-RTA, follow these steps to set up the microphone.

Open the DM-RTA software. In the top right corner, you will see a button labeled "48V." All of our calibration microphones require phantom 48V power, so go ahead and select the 48V button to highlight it.

Next, select the SPL meter tab and then select the Ref mic drop-down menu.

Select the microphone you are using. At the top of the screen, you will note that the Mic Gain slider has changed, and the Microphone is selected. The Mic Gain is now set for that particular microphone.

For instructions on how to install the DM-RTA software, refer to the installation guide applicable to your computer's Operating System here.
