Setup Instructions

  1. Unpack Components: Carefully remove all items from the packaging and inspect for any damage.
  2. Connect Receiver Power: Connect the included power adapter to the DC input on the rear of the receiver unit and plug it into a power outlet.
  3. Connect Audio Output: Connect the receiver's audio output to your audio system (mixer, amplifier, PA system) using either the 6.35mm (1/4") TRS Mix Output or the individual XLR Balanced Outputs.
  4. Install Batteries in Transmitters: Open the battery compartment on each bodypack transmitter and insert two AA batteries, observing correct polarity.
  5. Connect Microphones: Plug the 3-pin mini XLR connector of each lavalier or headset microphone into the corresponding jack on a bodypack transmitter.
  6. Power On: Turn on the receiver unit using its power switch. Then, turn on each bodypack transmitter.
  7. Frequency Synchronization (IR Sync):
    • On the receiver, select the desired channel (A, B, C, or D) for synchronization.
    • Press the 'SET' button on the receiver for the selected channel. The display will indicate it's ready for IR sync.
    • Align the IR port on the bodypack transmitter with the IR sensor on the receiver.
    • The frequency will automatically synchronize. Repeat for all four microphones.

Operating Instructions

Power On/Off

To power on the system, first turn on the receiver, then each bodypack transmitter. To power off, reverse the order: turn off transmitters first, then the receiver.

Frequency Adjustment

The system offers 200 adjustable frequencies (100 per microphone pair) to avoid interference and ensure clear audio transmission.

  • Auto Scan: The receiver can automatically scan and locate the best available frequency. This is typically initiated by pressing a dedicated 'SCAN' or 'SET' button on the receiver for a few seconds.
  • Manual Frequency Selection: You can manually cycle through available frequencies for each channel using the control buttons on the receiver. After selecting a new frequency, perform an IR sync with the corresponding transmitter.

Lock Function

To prevent accidental changes to settings during operation, the receiver's display can be locked.

  • To Lock/Unlock: Long press the 'SET' buttons on both sides of the display simultaneously for a few seconds. The display will indicate when it is locked or unlocked.

Volume Control

The system features volume control, typically adjusted via the connected audio mixer or amplifier. Ensure appropriate gain staging to prevent distortion or feedback.

Maintenance

  • Battery Replacement: Replace AA batteries in the bodypack transmitters when the low battery indicator appears on their LCD displays. Always use fresh, high-quality batteries.
  • Cleaning: Use a soft, dry cloth to clean the receiver and transmitters. Avoid using liquid cleaners or solvents, which can damage the electronic components.
  • Storage: When not in use for extended periods, remove batteries from transmitters and store the system in a cool, dry place away from direct sunlight and extreme temperatures.

Troubleshooting
