Setup and Operation
- Plug in the power supply and turn on the receiver.
- The receiver should be at least 3 feet off the ground for optimal transmission.
- Connect the antennas.
- The antennas should extend vertically.
- Depending on your setup, connect the appropriate outputs.
- Make sure the microphone and bodypack batteries are properly inserted.
- Turn on the microphones and bodypacks. They should automatically connect to the receiver.
- If necessary, use the frequency button on the mic (page 4) or the frequency button in the bodypack battery compartment (page 5) to change the frequency.
- Adjust channel volume as necessary.
Tip: To minimize feedback, avoid operating the microphones in close proximity of or in front of speakers.
Troubleshooting
| Problem | Solution |
| No sound or faint sound | • Verify all sound system connections or adjust channel volume as needed.• Verify that the receiver is connected to the mixer/amplifier. |
| • Verify your mics are turned on.• Check the mic’s frequency and adjust if necessary (see pages 4 and 5).• Make sure the batteries are installed correctly.• Change the battery if necessary. | |
| • Make sure AC adapter is securely connected to the unit and to the electrical outlet.• Make sure receiver is powered on. | |
| Audio artifacts or dropouts | • Change receiver and mic to a different channel.• Identify nearby sources of interference (cell phones, Wi-Fi access points, signal processor, etc.) and shutdown or remove source.• Change the microphones’ batteries.• System must be set up within recommended range and receiver kept away from metallic surfaces.• Microphone must be used in receiver’s line of sight for optimal sound. |
| Distortion | Reduce microphone channel volume. |
| Sound level variations when switching to different sources | Adjust microphone volume as necessary. |
| Transmitter information does not appear on the receiver LCD. | Microphone is off. Please turn it on. |
