- Microphone Connection:
Connect your compatible Audix microphone (e.g., ADX40, HT2) to the mini-XLR input on the APS-911.
- Output Connection:
Connect the 3-pin XLR output of the APS-911 to your mixer, audio interface, or other audio input device using a standard XLR cable.
Operating Instructions

Locate the power switch on the APS-911. Slide the switch to the "ON" position to power the unit. Slide it to "OFF" when not in use to conserve battery life.

- Monitoring Audio:
Ensure your mixer or audio interface input gain is set appropriately. Gradually increase the gain while speaking into the microphone to avoid sudden loud noises.
Maintenance
- Battery Replacement: Replace the AA battery when the power indicator (if present) dims or the microphone signal becomes weak or intermittent. Always use fresh, high-quality AA batteries.
- Cleaning: Clean the exterior of the APS-911 with a soft, dry cloth. Do not use liquid cleaners or solvents.
