3. Setup
3.1 Initial Charging
Before first use, fully charge both the transmitter and receiver units. Connect the provided USB charging cable to the transmitter unit, and then connect the other end to a standard USB power adapter (not included). The receivers charge when docked in the transmitter. Charging indicators will illuminate to show progress.
3.2 Connecting the System
- Power On: Press and hold the power button on the transmitter until the indicator lights illuminate. Similarly, power on each receiver unit.
- Pairing: The WP12 system is designed for automatic pairing. When the transmitter and receivers are powered on and within range, they should automatically establish a connection. Look for a stable indicator light on both units, typically indicating a successful connection. If pairing does not occur automatically, press the "PAIR" button on the receiver and the corresponding button on the transmitter (if available, otherwise power cycle both units).
- Connect to Instrument/Audio Source: Plug the transmitter into your guitar or other audio output device.
- Connect to Amplifier/Mixer: Plug the receiver(s) into your amplifier, mixer, or audio interface.
4. Operating Instructions
4.1 Operating Modes
The WP12 system offers four distinct operating modes to suit various audio setups:
- Left Channel Mode: Audio is transmitted to the left channel of the receiver output.
- Right Channel Mode: Audio is transmitted to the right channel of the receiver output.
- Stereo Mode: Audio is transmitted in stereo, utilizing both left and right channels.
- Mute Mode: Disables audio transmission.
Refer to the receiver unit's controls to switch between these modes. The specific method for mode selection (e.g., short press, long press of a button) will be indicated on the device or in quick start guides.
4.2 Volume Control and Mute
- Receiver Volume: Each receiver unit features dedicated volume controls (VOL+ / VOL-) to adjust the output level.
- Receiver Mute: The receiver also allows for muting the audio output.
- Transmitter Mute: The transmitter unit includes a one-button mute function for quick silencing of the input signal.
4.3 Multi-Receiver Operation
The M-Vave WP12 allows a single transmitter to broadcast to multiple receiver units simultaneously. This is ideal for scenarios requiring multiple monitoring points or distributing the audio signal to different destinations. Ensure all receivers are paired with the same transmitter for this functionality.
5. Charging and Battery Life
The M-Vave WP12 system is equipped with rechargeable Lithium Ion batteries.
- Transmitter Battery Life: Up to 24 hours on a full charge.
- Receiver Battery Life: Up to 6 hours on a full charge.
To charge, connect the USB charging cable to the transmitter. The receivers charge automatically when docked in the transmitter. Battery indicator lights on the units will show the charging status and remaining battery level. For optimal battery longevity, avoid fully discharging the units frequently.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the units. Do not use liquid cleaners or solvents.
- Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: If storing for extended periods, charge the batteries to approximately 50% every few months to prevent deep discharge.
