3. Audio Output Connection
Connect the receiver to your audio mixer or amplifier. You have two options:
- Individual XLR Outputs: Use XLR cables to connect each of the eight balanced XLR outputs (labeled A through H) to individual channels on your mixer for separate control of each microphone.
- Mixed 1/4" Output: Use the provided 1/4" audio cable to connect the mixed output to a single input on your mixer. This combines all eight microphone signals into one output.
4. Power Connection
Connect the AC-DC adapter to the receiver's power input and then plug it into a suitable power outlet. Do not power on the unit yet.
5. Transmitter Battery Installation
Each headset microphone connects to a belt-pack transmitter. Open the battery cover on each belt-pack transmitter and insert two AA batteries, observing the correct polarity. Close the battery cover securely.

6. Headset Microphone Connection
Connect each headset microphone to its corresponding belt-pack transmitter's headset input. Ensure the connection is firm.
Operating Instructions
1. Powering On
First, power on your audio mixer/amplifier. Then, press the power button on the receiver unit. The LCD display will illuminate. Finally, switch on each belt-pack transmitter.
2. Frequency Selection and Synchronization
Each channel on the receiver and each transmitter has 100 selectable frequencies. To ensure optimal performance and avoid interference, it is crucial to synchronize the transmitter and receiver for each microphone.
- Manual Frequency Selection: On the receiver, use the channel selection buttons to choose a desired frequency for each channel. Observe the RF level indicator to select a clear frequency with minimal interference.
- Automatic Transmitter Setup (Synchronization): Once a frequency is selected on the receiver, activate the automatic synchronization function (refer to the receiver's specific button/menu for "SYNC" or "IR"). Hold the corresponding belt-pack transmitter close to the receiver's IR sensor. The receiver will automatically transmit the selected frequency to the transmitter, synchronizing them. Repeat this process for all 8 channels.
The backlit LCD display on the receiver will show the RF (Radio Frequency) level, AF (Audio Frequency) level, selected Channel Frequency, and mute status, allowing you to monitor the system's performance.
3. Adjusting Volume
Each channel on the receiver has an individual volume control knob. Adjust these knobs to set the desired output level for each microphone. Further fine-tuning can be done on your audio mixer.
4. Operating Range
The system has an operating range of up to 80 meters (approximately 300 feet) under ideal conditions. Obstacles, walls, and other RF interference sources can reduce this range. Maintain a clear line of sight between the transmitters and the receiver antennas whenever possible.
5. Powering Off
When finished, first switch off all belt-pack transmitters. Then, power off the receiver unit. Finally, power off your audio mixer/amplifier.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the receiver and transmitters. Do not use liquid cleaners or solvents.
- Battery Replacement: Replace AA batteries in the belt-pack transmitters when the low battery indicator appears on the transmitter or receiver display, or when audio quality degrades. Always use fresh, high-quality batteries.
- 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.
- Antennas: Handle antennas carefully to avoid bending or breaking.
