Connecting the Transmitter

1. Connect the provided USB cable to the 5V==1A port on the transmitter unit. Connect the other end of the USB cable to a suitable USB power source (e.g., a USB wall adapter, not included, or a USB port on your audio source device if available).
2. Using the supplied RCA cable and adaptor, connect the 'LINE IN' RCA inputs on the transmitter to the subwoofer output (LFE or Sub Out) of your audio source (e.g., AV receiver, pre-amplifier). Ensure correct polarity (red to red, white to white if applicable, or use the single LFE connection).
3. Place the transmitter in a location that allows for a clear line of sight to the receiver, ideally within 30 meters.

Connecting the Receiver

1. The receiver unit is designed to plug directly into compatible KEF subwoofers (Kube8b, Kube10b, Kube12b, KF92) via a dedicated port. Align the receiver with the port on your subwoofer and gently push it in until it is securely seated.
2. Ensure the subwoofer is powered on. The receiver draws power directly from the subwoofer.

Pairing the Units

The transmitter and receiver units are typically pre-paired from the factory. If they do not connect automatically, follow these steps to manually pair them:

1. Ensure both the transmitter and receiver units are powered on.
2. Press and hold the 'PAIR' button on the transmitter unit for a few seconds until its indicator light begins to flash.
3. Within 30 seconds, press and hold the 'PAIR' button on the receiver unit (located on the side or top, depending on the model) until its indicator light also begins to flash.
4. Once both lights stop flashing and remain solid, the units are successfully paired.

4. Operation

Once the KEF KW1TXRX units are set up and paired, they will automatically establish a wireless audio link when powered on. The system operates on the 5GHz frequency band to minimize interference and ensure stable, high-fidelity audio transmission.

• Audio Quality: The system supports audio transmission up to 24-bit/48kHz, ensuring that the subwoofer receives a high-resolution signal.
• Latency: With a latency of less than 17ms, the audio signal is transmitted with minimal delay, ensuring synchronization with your main speakers.
• Range: The effective operating range is up to 30 meters (line of sight). Obstacles suchs as walls or large furniture may reduce this range.

5. Maintenance

To ensure the longevity and optimal performance of your KEF KW1TXRX Wireless Subwoofer Adapter Kit, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to wipe the surfaces of the transmitter and receiver. Do not use liquid cleaners, aerosols, or abrasive chemicals, as these can damage the finish or internal components.
• Placement: Avoid placing the units in direct sunlight, near heat sources, or in areas with high humidity or extreme temperatures.
• Storage: If storing the units for an extended period, disconnect them from power and store them in a cool, dry place.
