Setup
- Powering the Receiver (PR-8):
For indoor use, connect the provided DC9V/500mA power adapter to the receiver's power input and plug it into a wall outlet. For outdoor or portable use, open the battery compartment on the underside of the receiver and insert two (2) 1.5V AA batteries, ensuring correct polarity. - Connecting the Receiver to an Audio System:
Connect one end of the 6.35mm audio output cable to the audio output socket on the receiver. Connect the other end to the input of your speaker, mixer, or sound card. - Powering the Transmitter (ST-4):
Open the battery compartment on the ST-4 transmitter and insert one (1) 1.5V AA battery, observing correct polarity. - Attaching the Transmitter:
The ST-4 transmitter features a clip-on design. Securely attach it to the bell of your saxophone or other wind instrument. Adjust the flexible gooseneck to position the microphone capsule appropriately for optimal sound capture. - Antenna Setup:
Ensure both antennas on the PR-8 receiver are securely attached and positioned upright for best signal reception.

Operating Instructions
- Power On/Off:
Press and hold the power button on both the PR-8 receiver and ST-4 transmitter until their respective displays illuminate. To power off, press and hold the power button again. - Frequency Synchronization (IR Sync):
Ensure both units are powered on. On the PR-8 receiver, select your desired channel/frequency using the control buttons. Then, align the IR windows of the receiver and transmitter (usually marked 'IR') and press the 'IR Sync' button on the receiver. The frequency will be automatically transferred to the transmitter. - Adjusting Volume:
Use the volume knob on the PR-8 receiver to adjust the output level to your audio system. Start with a low volume and gradually increase it to avoid feedback or clipping. - Mute Function:
The ST-4 transmitter has a mute button. Press it briefly to mute the microphone output. Press again to unmute. The LCD display on the receiver will indicate the mute status. - Monitoring Display:
The LCD display on the PR-8 receiver shows important information such as RF (Radio Frequency) level, AF (Audio Frequency) level, current channel, and operating frequency. Monitor these indicators for optimal performance.

Maintenance
- Battery Replacement: Replace batteries in both the receiver and transmitter when the low battery indicator appears on the LCD display or when performance degrades. Always use fresh, high-quality 1.5V AA batteries.
- Cleaning: Use a soft, dry cloth to clean the exterior of both units. For the microphone capsule and rubber instrument cover, a slightly damp cloth can be used, but ensure no moisture enters the electronic components.
- Storage: When not in use for extended periods, remove batteries from both units to prevent leakage. Store the system in its original carrying case in a cool, dry place away from direct sunlight and extreme temperatures.
- Antenna Care: Handle antennas with care. Avoid bending them excessively or applying undue force, as this can damage the internal wiring and affect signal quality.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Receiver/Transmitter not powered on; Low batteries; Incorrect frequency sync; Audio cable disconnected; Mute function active. | Ensure both units are on; Replace batteries; Perform IR sync; Check audio cable connections; Deactivate mute on transmitter. |
| Poor sound quality (static, dropouts) | Interference; Out of range; Low batteries; Obstructions between units. | Change frequency/channel; Reduce distance between units; Replace batteries; Ensure clear line-of-sight. |
| Receiver not powering on | Power adapter faulty/disconnected; Dead batteries. | Check power adapter connection and functionality; Replace AA batteries. |
| Transmitter not powering on | Dead battery. | Replace AA battery. |
User Tips
- Optimal Placement: Experiment with the microphone's position on your instrument to find the sweet spot that captures the best tone and minimizes key noise.
- Line of Sight: For the most stable connection and maximum range, try to maintain a clear line of sight between the transmitter and receiver antennas.
- Battery Management: Always carry spare batteries, especially for live performances or extended outdoor use.
- Interference Check: If you experience interference, try changing the operating frequency on the receiver and re-syncing the transmitter. Avoid placing the receiver near other wireless devices or strong electromagnetic fields.
