crophone into the preamplifier's Tini Q-G connector. (NOTE:
The Power LED Indicator will remain lit in both the Mute and
On microphone modes.)
2. Plug the XLR cable from the preamplifier into the respective au-
dio device microphone input.
3. Switch the Mic Mute/On switch to the On position.
4. Adjust the gain level of the audio input device, if necessary.
