4.2. Connecting the Transmitter to a Microphone
- Ensure your wired microphone is powered off.
- Plug the XLR output of your wired microphone directly into the XLR input of the PTU-X Transmitter.
- Secure the connection by tightening the adjustable locking knob on the transmitter. This minimizes movement noise and ensures a stable audio signal.
- If using a condenser microphone, ensure the +48V phantom power switch on the transmitter is set to ON. For dynamic microphones, keep it OFF.

4.4. Powering On and Frequency Synchronization
- Press and hold the POWER button on both the transmitter and receiver to turn them ON. The display will light up.
- The units should automatically synchronize. If not, or if you experience interference, you can manually change the channel.
- To change the channel, press the 'CH' button on the transmitter. The display will show the current channel (0-F).
- To synchronize the receiver with the new channel, press the 'SYNC' button on the receiver. The receiver will scan and lock onto the transmitter's frequency.

5. Operating Instructions
5.1. MIC/LINE Gain Control
The PTU-X features a MIC/LINE switch to optimize input sensitivity:
- MIC Mode: Use for standard microphone inputs.
- LINE Mode: Use for line-level audio sources, which typically have a stronger signal. This mode reduces the gain by 5dB to prevent distortion.
Adjust this switch based on your audio source to achieve the best sound quality and prevent clipping.

5.2. Phantom Power (+48V)
The transmitter is equipped with a +48V phantom power switch. This is essential for operating condenser microphones, which require external power. Ensure this switch is set correctly for your microphone type:
- ON: For condenser microphones.
- OFF: For dynamic microphones (phantom power is not needed and can potentially damage some dynamic mics).
5.3. Operating Range and Battery Life
The PTU-X system provides an operating distance of up to 100 feet (30 meters) for uninterrupted audio transmission. The built-in 1000mAh rechargeable battery offers approximately 7 hours of continuous use on a full charge, making it suitable for extended performances.

9. User Tips
- Optimal Channel Selection: If you experience any signal drops or interference, try cycling through the 16 available frequencies using the 'CH' button on the transmitter and then syncing the receiver. This can help find the clearest channel in your environment.
- Microphone Compatibility: Remember to correctly set the +48V phantom power switch based on whether you are using a condenser or dynamic microphone to ensure proper operation and prevent potential damage.
- Battery Management: For prolonged events, consider fully charging both units before use. The 7-hour battery life is generally sufficient, but having a power bank or access to charging can be beneficial for all-day sessions.
- Multiple Units: If you plan to use multiple wireless systems simultaneously, ensure each system is set to a different frequency to avoid cross-interference.
