4. Setup Instructions
Follow these steps to set up your ACEMIC AT-5 wireless microphone system:
4.1. Charging the Units
- Connect the USB-C charging cable to the charging ports on both the transmitter and receiver units.
- Plug the other end of the cable into a USB power adapter (not included) or a powered USB port.
- The charging indicator will illuminate. A full charge typically takes 2.5 to 3 hours.
- Once fully charged, the indicator light will change or turn off, depending on the unit.

4.2. Attaching the Transmitter to Your Instrument
- Select a suitable location on your acoustic guitar, typically near the sound hole, where the transmitter can be securely attached without obstructing your playing.
- Peel the backing from one of the Velcro adhesive attachments.
- Apply the adhesive side firmly to the chosen spot on your guitar.
- Attach the transmitter unit to the Velcro. Ensure it is secure.
- Adjust the flexible gooseneck microphone to point towards the sound hole or strings for optimal sound capture.


4.3. Connecting the Receiver
- Ensure the antenna on the receiver is correctly installed and extended.
- Plug the 6.35mm audio jack of the receiver directly into the input of your amplifier, PA system, or audio mixer.
- If your device requires a 3.5mm input, use the provided 3.5mm audio jack adapter.
4.4. Pairing the Units
The ACEMIC AT-5 system features automatic infrared pairing:
- Power on both the transmitter and the receiver units.
- Place the IR sensors of the transmitter and receiver close to each other (within a few inches).
- The units will automatically pair. A successful connection is usually indicated by a stable light on both units.

5. Operation
5.1. Powering On/Off
Press and hold the power button on each unit to turn it on or off.
5.2. Channel Selection
The system offers 16 preset groups of adjustable channels to mitigate potential interference. If you experience interference, you can manually switch channels on the receiver using the channel switch button. Ensure that the transmitter and receiver are on the same channel for proper operation.

5.3. Microphone Placement
Adjust the flexible gooseneck microphone to achieve the desired sound. Experiment with different angles and distances from the sound hole or strings to find the optimal position for your instrument and playing style. The built-in high-sensitivity condenser microphone is designed to capture clear and realistic audio.

5.4. Wireless Transmission
The ACEMIC AT-5 system uses UHF frequency for stable transmission up to 130 feet (approximately 40 meters) in open areas. Performance may vary depending on environmental factors and obstacles.

6. Maintenance
6.1. Cleaning
Wipe the units with a soft, dry cloth. Do not use liquid cleaners or solvents, as they may damage the finish or internal components.
6.2. Storage
When not in use, store the ACEMIC AT-5 system in its carrying bag in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the units are turned off before storage.
6.3. Battery Care
To prolong battery life, avoid completely discharging the units regularly. Recharge them periodically, even if not in frequent use.
7. Troubleshooting
If you encounter issues with your ACEMIC AT-5 system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Units not powered on Units not paired Receiver not connected to audio input Receiver antenna not installed/extended Low battery | Ensure both transmitter and receiver are powered on. Re-pair the units using the infrared sensors. Verify the receiver is securely plugged into your amplifier/mixer. Ensure the receiver antenna is properly installed and extended. Charge both units fully. |
| Interference or static noise | Nearby electronic devices Other wireless signals Obstacles between units | Move away from potential sources of interference. Change the operating channel on the receiver. Ensure a clear line of sight between the transmitter and receiver. |
| Poor sound quality (e.g., muffled, weak) | Incorrect microphone placement Microphone too far from sound source Low battery | Adjust the gooseneck microphone closer to the sound hole or strings. Ensure units are fully charged. |
| Short transmission range | Obstacles blocking signal Environmental factors Low battery | Minimize obstacles between transmitter and receiver. Ensure units are fully charged. |
| Transmitter not attaching securely | Velcro adhesive worn out | Use a fresh Velcro adhesive attachment. (5 spare pieces are included). |
