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.
Phantom power may be applied with a 9 V battery in place or
removed. With the battery installed, the MX1BP will silently and au-
tomatically switch to the battery reserve should phantom power fail.
Battery depletion will not occur while phantom power is applied.
