Each microphone features a high-quality dynamic cardioid cartridge designed for precise sound capture and noise rejection, ensuring clear audio.

The handheld microphones are constructed with durable all-metal housing, feature a comfortable grip, and include a low battery indicator (screen turns red) and a recessed on/off switch to prevent accidental activation.

The quad-channel UHF wireless receiver features an LCD screen displaying frequency, individual volume controls for each channel, and multiple output options including balanced XLR and a 1/4'' audio jack. It requires an amplifier or speaker for sound output.

The receiver provides four balanced XLR outputs for noise-free signal transmission and diversified mixing options.

Snap-on BNC antennas allow for quick and secure connections, facilitating easy setup and dismantling.

Color-coded anti-rolling rings are included to prevent microphones from rolling off surfaces and for easy identification.
3. Setup Instructions
- Unpack Components: Carefully remove all items from the packaging and verify that all listed components are present.
- Install Antennas: Screw the two antennas onto the corresponding ANT A and ANT B connectors on the rear of the receiver. Ensure they are securely fastened and positioned for optimal reception.
- Power Connection: Connect the power adapter to the receiver's power jack and then plug it into a suitable power outlet.
- Audio Output Connection:
- For individual microphone outputs, connect XLR cables from the receiver's balanced XLR outputs (AF OUTPUT 1-4) to your mixer or amplifier's input channels.
- For a mixed output of all four microphones, connect the 1/4'' audio cable from the receiver's MIX OUT jack to your mixer or amplifier's input.
Note: An amplifier or speaker is required to output sound from the system.
- Microphone Batteries: Insert two AA batteries into each handheld microphone, ensuring correct polarity. The system includes 8 AA batteries.
- Power On: Turn on the receiver using the ON/OFF button. Then, turn on each handheld microphone using its ON/OFF switch. The receiver's LCD screen will display the frequency and signal status.
- Volume Adjustment: Adjust the individual volume controls (VOL 1-4) on the receiver to balance the audio levels of each microphone.

The system is designed for instant wireless operation with a memory switch that saves your last settings for quick recall.

The system offers wide compatibility with various audio output devices.
4. Operating Instructions
4.1 Microphone Usage
- Hold the microphone approximately 2-6 inches from your mouth for optimal sound pickup.
- Avoid covering the microphone grille with your hand, as this can affect sound quality and signal.
- The microphone's screen will turn red when the battery level is low, indicating it's time to replace the AA batteries.
- Utilize the included anti-rolling rings to prevent microphones from rolling off flat surfaces.
4.2 Receiver Operation
- The LCD display on the receiver shows the active frequency and signal strength for each channel.
- Adjust the individual volume knobs (VOL 1-4) on the receiver to control the output level of each microphone independently.
- The memory switch feature allows the receiver to retain its last operational settings even after being unplugged, enabling quick power-on without re-configuration.
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the receiver and microphones. Avoid using harsh chemicals or abrasive cleaners.
- Battery Replacement: Replace AA batteries in the microphones promptly when the low battery indicator appears to ensure uninterrupted performance.
- Storage: When not in use for extended periods, store the system in a dry, cool place, away from direct sunlight and extreme temperatures. Remove batteries from microphones before long-term storage.
- Antenna Care: Handle antennas carefully to prevent bending or damage. Ensure they are properly connected for optimal signal.
6. Troubleshooting
Common Issues and Solutions
- No Sound Output:
- Ensure the receiver is powered on and connected to an amplifier/speaker.
- Check that microphones are powered on and have fresh batteries.
- Verify all audio cables are securely connected between the receiver and the output device.
- Adjust the volume controls on both the receiver and the connected audio device.
- Cutoffs or Static Noise:
- Interference: Avoid using multiple personal electronic devices (e.g., cell phones, laptops) simultaneously near the system, as they can cause interference.
- Feedback: Avoid pointing microphones directly at speakers. Adjust microphone and speaker placement to minimize feedback.
- Range: Ensure the microphones are within the 260ft operating range of the receiver. Obstacles can reduce effective range.
- Antennas: Check that antennas are properly installed and positioned.
- Microphone Not Connecting:
- Ensure the microphone has fresh batteries and is powered on.
- Verify the receiver is powered on.
- Since this system uses fixed frequencies, ensure no other wireless devices are operating on the same frequencies.
- Multiple Systems Operation:
- The UHF fixed frequency series is designed for single-system operation (4 channels at a time). For multiple systems, consider Phenyx Pro models with adjustable frequencies (e.g., PTU-5200 series).

To prevent cutoffs and static, avoid using personal electronics near the system and prevent microphones from pointing directly at speakers.
