3. Setup
3.1 Battery Installation
- Unscrew the lower part of the microphone handle to access the battery compartment.
- Insert two AA batteries (not included) into the compartment, ensuring correct polarity (+/-).
- Securely screw the handle back into place.
3.2 RF Power Switch Setting
Under the battery cover, locate the RF power switch. This switch allows you to select the transmission power:
- HI: For a stabler signal transmission, recommended for longer distances or environments with potential interference.
- LO: For power saving, suitable for shorter distances or when battery life is a priority.
3.3 Pairing with Receiver (IR Synchronization)
The PWH-12 microphone is designed to pair with Phenyx Pro PTU-1U or PTU-2U true diversity systems. Refer to your receiver's manual for specific instructions on initiating IR synchronization. Generally, this involves:
- Turn on the receiver and the microphone.
- On the receiver, activate the IR sync function (usually a button labeled 'SYNC' or 'IR').
- Align the IR sensor on the microphone (typically near the LCD screen) with the IR transmitter on the receiver.
- The microphone and receiver will automatically synchronize to the same frequency. Confirm the channel displayed on both devices matches.
4. Operating Instructions
4.1 Powering On/Off and Mute Function
The microphone features a multi-function ON/MUTE/OFF button:
- To Power On: Press and hold the button until the LCD screen illuminates.
- To Mute: Briefly press the button during operation. The LCD will indicate 'MUTE'.
- To Unmute: Briefly press the button again.
- To Power Off: Press and hold the button until the LCD screen turns off.
4.2 Monitoring Status
The LCD screen on the microphone displays important information, including:
- Current operating frequency/channel.
- Battery level indicator.
- Mute status.
Regularly check the battery indicator to ensure sufficient power for your performance.
4.3 Microphone Technique
The PWH-12 features a cardioid polar pattern, meaning it is most sensitive to sound coming from the front and least sensitive to sound from the rear. This helps to reduce feedback and isolate the desired sound source.
- Hold the microphone approximately 2-6 inches from your mouth for optimal vocal pickup.
- Avoid covering the microphone grille with your hand, as this can affect sound quality and increase the likelihood of feedback.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your microphone.
- Cleaning: Use a soft, dry cloth to clean the exterior of the microphone. Do not use abrasive cleaners or solvents.
- Storage: Store the microphone in a dry, cool place away from direct sunlight and extreme temperatures.
- Battery Care: Remove batteries if the microphone will not be used for an extended period to prevent leakage.
- Handling: Avoid dropping or subjecting the microphone to strong impacts, as this can damage internal components.
6. Troubleshooting
If you encounter issues with your PWH-12 microphone, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from microphone | Microphone is off; low/dead batteries; microphone muted; not paired with receiver; receiver input issues. | Ensure microphone is on; replace batteries; unmute microphone; perform IR synchronization; check receiver connections and volume. |
| Interference or static | Other wireless devices on same frequency; too far from receiver; obstacles blocking signal; RF power set to LO. | Change frequency on receiver and re-sync microphone; reduce distance to receiver; ensure clear line of sight; set RF power switch to HI. |
| Low volume or weak signal | Microphone too far from mouth; RF power set to LO; low microphone sensitivity. | Adjust microphone position; set RF power switch to HI; check receiver gain settings. |
| Microphone not syncing | IR sensors not aligned; receiver not in sync mode; incompatible receiver. | Ensure IR sensors are aligned and close; activate sync mode on receiver; confirm receiver is a compatible Phenyx Pro PTU-1U/PTU-2U model. |
