4. Setup Instructions
4.1 Receiver Setup
- Placement: Place the receiver on a stable, flat surface, ensuring adequate ventilation. Position it within the desired operating range of the microphones, ideally with a clear line of sight.
- Connect Antennas: Screw the two included antennas onto the ANT A-B and ANT C-D connectors on the rear panel of the receiver. Ensure they are securely tightened and positioned vertically for optimal signal reception.
- Connect Power: Connect the external wall wart power supply to the DC INPUT port on the rear of the receiver, then plug the power supply into a suitable electrical outlet.
- Audio Output Connection: Connect the receiver to your audio mixer, amplifier, or sound system using the provided audio cable. You can use the MIX OUT (1/4" unbalanced) for a combined output, or the individual BALANCED A, B, C, D (XLR) outputs for separate channel control.

4.2 Microphone Setup (Handheld & Bodypack)
- Install Batteries: Open the battery compartment of each handheld microphone and bodypack transmitter. Insert two AA batteries (not included), ensuring correct polarity.
- Attach Lapel Microphones: For bodypack transmitters, plug the lavalier/lapel microphone into the input jack on the bodypack. Secure the lapel microphone to clothing, approximately 6-8 inches from the speaker's mouth.
- Power On: Press and hold the power button on each handheld microphone and bodypack transmitter to turn them on. The display will illuminate.



4.3 Frequency Synchronization (IR Sync)
To establish a wireless connection, the microphones/bodypacks must be synchronized with the receiver.
- Power On Receiver: Turn on the receiver using the POWER button on the front panel.
- Select Channel: On the receiver, select the desired channel (CH A, CH B, CH C, or CH D) for the microphone you wish to sync.
- Initiate Scan (Optional but Recommended): Press the 'SCAN' button on the receiver for the selected channel. The receiver will automatically search for an available, clear frequency.
- Activate IR Sync on Receiver: Press the 'IR SYNC' button on the receiver for the selected channel. The IR indicator on the receiver will flash.
- Align Transmitters: Hold the handheld microphone or bodypack transmitter with its IR window facing the IR window on the receiver, typically within a few inches.
- Confirm Sync: The display on the microphone/bodypack will show the synchronized frequency, and the RF indicator on the receiver will illuminate steadily, indicating a successful connection.
- Repeat this process for each microphone/bodypack.

5. Operating Instructions
5.1 Power On/Off
- Receiver: Press the 'POWER' button on the front panel.
- Handheld Microphones/Bodypacks: Press and hold the 'POWER' button on the device until the display illuminates (for ON) or turns off (for OFF).
5.2 Volume Control
Each channel on the receiver has an independent volume control knob. Adjust these knobs to achieve the desired audio level for each microphone. Start with the volume low and gradually increase it to avoid sudden loud sounds.
5.3 Mute Function
Both handheld microphones and bodypack transmitters feature a MUTE function. Press the 'MUTE' button on the microphone/bodypack to temporarily silence the audio transmission without turning off the device. Press it again to unmute.
5.4 Channel Selection and Auto Scan
The system offers 1000 channels. If you experience interference, you can change the operating frequency:
- On the receiver, press the 'SCAN' button for the desired channel. The receiver will automatically find and select a clear frequency.
- Once a new frequency is displayed, perform an IR Sync (as described in Section 4.3) to synchronize the corresponding microphone/bodypack to the new frequency.
5.5 Usage Tips
- Operating Distance: Maintain a line of sight between the microphones/bodypacks and the receiver for optimal performance. The system has a working distance of up to approximately 200 feet.
- Avoid Obstructions: Walls, metal objects, and large crowds can reduce the effective range and cause signal drops.
- Battery Life: Monitor the battery indicators on the microphones/bodypacks. Replace batteries promptly when they are low to avoid interruptions during use.
- Feedback Prevention: Position microphones away from speakers to prevent audio feedback. Adjust microphone gain and speaker volume carefully.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the receiver and microphones. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace AA batteries in handheld microphones and bodypacks as needed. Always use fresh batteries for best performance.
- Storage: When not in use for extended periods, remove batteries from microphones/bodypacks and store the system in a cool, dry place, away from direct sunlight and extreme temperatures.
- Antennas: Ensure antennas are not bent or damaged. Handle them carefully.
7. Troubleshooting
If you encounter issues with your wireless microphone system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from microphone | Microphone/bodypack not powered on Low or dead batteries Microphone/bodypack muted Not synchronized with receiver Receiver volume too low Audio cable disconnected | Ensure microphone/bodypack is on Replace batteries Unmute microphone/bodypack Perform IR Sync (Section 4.3) Increase receiver channel volume Check audio cable connections |
| Interference or static | Other wireless devices nearby Operating on a crowded frequency Obstructions between transmitter and receiver | Move away from other wireless devices Use Auto Scan to find a clear frequency and re-sync Ensure clear line of sight; reposition receiver/transmitters |
