Setup Guide

Connecting the KW1RX Receiver

The KW1RX receiver is designed to connect directly to compatible KEF subwoofers. Follow these steps for proper connection:

1. Locate the dedicated KW1 port on your KEF subwoofer. This port is typically found on the rear panel of the subwoofer.
2. Align the KW1RX receiver with the KW1 port on the subwoofer. Ensure the connectors on the receiver match the port.
3. Gently push the KW1RX receiver into the KW1 port until it is securely seated. It should fit snugly and make a firm connection.
4. Once connected, the KW1RX receiver will draw power directly from the subwoofer. No separate power adapter is needed for the receiver.

Pairing with the KW1 Transmitter (Sold Separately)

For the KW1RX receiver to function, it must be paired with a KEF KW1 Wireless Subwoofer Transmitter. The transmitter connects to your audio source (e.g., AV receiver, pre-amplifier). Follow these steps to establish a wireless connection:

1. Ensure both the KW1RX receiver (connected to your subwoofer) and the KW1 transmitter (connected to your audio source) are powered on.
2. On the KW1RX receiver, locate the 'PAIR' button. This is typically a small, recessed button on the top or side of the unit.
3. Press and hold the 'PAIR' button on the KW1RX receiver for approximately 3 seconds until the status indicator light begins to flash rapidly. This indicates it is in pairing mode.
4. Within 30 seconds, press and hold the 'PAIR' button on the KW1 transmitter (refer to the transmitter's manual for its exact location) until its status indicator light also flashes rapidly.
5. Both units will search for each other. Once a connection is established, the status indicator lights on both the receiver and transmitter will turn solid, indicating a successful pairing.
6. If pairing fails, ensure both units are within range (up to 15 meters line of sight) and repeat the pairing process.

Operation

Once the KW1RX receiver is successfully paired with the KW1 transmitter, it will automatically receive audio signals from your source device. The receiver operates on 5.2 GHz and 5.8 GHz selectable digital wireless links to ensure stable and near-lossless audio transmission.

• Status Indicator Light: Observe the LED indicator on the KW1RX. A solid light indicates a stable connection. A flashing light typically indicates pairing mode or a lost connection.
• Automatic Connection: After initial pairing, the KW1RX and KW1 transmitter should automatically reconnect when both are powered on and within range.
• Adding a Second Subwoofer: The KW1 system allows for a single transmitter to deliver audio to two KW1RX receivers, enabling the use of two subwoofers for enhanced bass performance and room coverage. Simply connect a second KW1RX to another compatible KEF subwoofer and pair it using the same method.

Care and Maintenance

To ensure the longevity and optimal performance of your KEF KW1RX Wireless Subwoofer Receiver, follow these simple care guidelines:

• Cleaning: Use a soft, dry, lint-free cloth to clean the exterior of the receiver. Do not use liquid cleaners, aerosols, or abrasive chemicals, as these can damage the finish or internal components.
• Placement: Ensure the receiver is not exposed to extreme temperatures, direct sunlight, or high humidity. While connected to the subwoofer, ensure adequate ventilation around the subwoofer's rear panel.
• Handling: Handle the receiver with care. Avoid dropping it or subjecting it to strong impacts.
• Storage: If storing the receiver for an extended period, disconnect it from the subwoofer and store it in a cool, dry place, preferably in its original packaging.
