5. Setup Guide
5.1 Receiver Setup
- Placement: Position the receiver in a stable location, preferably within a 19" equipment rack. Ensure adequate ventilation.
- Antenna Connection: Screw the four antennas securely into their respective ports on the rear of the receiver. Angle them for optimal signal reception.
- Power Connection: Connect the AC-DC power adapter to the receiver's DC 12V input and then plug it into a power outlet. Do not power on yet.
- Audio Output: Connect the receiver to your audio mixer, amplifier, or sound system. Use the individual XLR outputs for separate microphone control or the 1/4" mixed output for a combined signal.
5.2 Microphone Setup
- Battery Installation: Unscrew the bottom part of each handheld microphone. Insert two AA batteries, observing the correct polarity (+/-). Screw the bottom back on securely.
- Power On: Press and hold the power button on each microphone to turn it on. The LCD display will illuminate.
5.3 System Overview
6. Operating Instructions
6.1 Powering On/Off
- Receiver: Press the power button on the front panel of the receiver. The LCD displays will light up.
- Microphones: Press and hold the power button on each microphone until the display illuminates.
- To power off, repeat the steps.
6.2 Frequency Synchronization
The system features automatic synchronization between the receiver and microphones:
- Ensure both the receiver and the desired microphone are powered on.
- On the receiver, select the desired channel (CH1 or CH2) using the channel selection buttons.
- Press the 'SET' button on the receiver for the chosen channel. The receiver will enter synchronization mode.
- Hold the microphone close to the receiver's IR sensor (usually near the display) until the frequency on the microphone's display matches the receiver's display.
- Repeat for the second microphone if using both.
6.3 Adjusting Volume
Each channel on the receiver has an independent volume control knob. Rotate the knob clockwise to increase volume and counter-clockwise to decrease it. Adjust to a suitable level to avoid distortion.
6.4 Changing Frequencies
If you experience interference, you can manually change the operating frequency:
- On the receiver, press the 'UP' or 'DOWN' buttons for the desired channel to cycle through available frequencies.
- Once a clear frequency is found, perform the synchronization process (Section 6.2) to update the microphone.
7. Maintenance
7.1 Cleaning
- Wipe the receiver and microphones with a soft, dry cloth.
- Do not use liquid cleaners or abrasive materials.
7.2 Battery Replacement
When the microphone's LCD display indicates low battery, replace the AA batteries promptly to ensure uninterrupted performance. Always replace both batteries in a microphone at the same time.
7.3 Storage
When not in use for extended periods, remove batteries from the microphones and store the system in a cool, dry place away from direct sunlight and extreme temperatures.
8. Troubleshooting
If you encounter issues, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Receiver or microphone not powered on; cables incorrectly connected; volume too low; microphone batteries dead. | Ensure all devices are powered on. Check audio cable connections. Increase receiver volume. Replace microphone batteries. |
| Interference or static | Operating frequency interference; receiver too far from microphones; obstacles blocking signal. | Change operating frequency (Section 6.4). Reduce distance between microphones and receiver. Ensure clear line of sight. |
| Microphone not syncing | Microphone not close enough to IR sensor; synchronization process not initiated correctly. | Ensure microphone IR sensor is facing receiver IR sensor and is within a few inches. Re-initiate synchronization (Section 6.2). |
| Short operating range | Antennas not properly connected or positioned; environmental interference. | Check antenna connections and position. Try different frequencies. Avoid placing receiver near large metal objects. |
