5. Operating Instructions
- Power On System: First, turn on the receiver unit using its power button. The orange LED displays for each channel should illuminate, showing their respective frequencies.
- Power On Bodypacks: Next, turn on each bodypack transmitter using the ON/OFF switch. The bodypack's display will show its operating frequency. Ensure the bodypack's frequency matches one of the receiver's channels.
- Adjust Volume: Use the individual volume control knobs on the front panel of the receiver to adjust the output level for each microphone channel. Start with a low volume and gradually increase it to avoid feedback.
- Microphone Usage: Position the lavalier microphone approximately 6-8 inches from your mouth, clipped to clothing. For headset microphones, position the boom arm so the microphone is near the corner of your mouth.
- Monitoring: Monitor the audio output through your connected sound system. The RF and AF indicators on the receiver will show signal presence and audio level.
- Range: Maintain a line of sight between the bodypack transmitters and the receiver for optimal performance, up to 350 feet. Obstacles can reduce this range.
- Power Off: When finished, first turn off all bodypack transmitters, then power off the receiver unit.
