Setup and Installation
Before beginning installation, ensure all components are present: the FW1 Wireless Subwoofer, AC Power cord, Quick Start Guide, and Warranty Card.
Placement
Position the subwoofer on a stable, flat surface, ideally on the floor, to allow for optimal bass dispersion. Consider placing it near a wall or in a corner to enhance bass response, but experiment with different locations to find the best sound for your room.
Power Connection
- Connect the supplied AC power cord to the subwoofer's power input.
- Plug the other end of the power cord into a suitable wall outlet.
Wireless Setup (DTS Play-Fi)
For wireless integration with a Philips soundbar, speakers, or TV, the FW1 subwoofer utilizes DTS Play-Fi technology. This allows for a flexible, multi-room audio system.
- Ensure your primary Philips audio device (e.g., soundbar) is already set up with DTS Play-Fi.
- Power on the FW1 subwoofer. It will automatically enter pairing mode or can be manually set to pairing mode via its controls.
- Use the Philips Sound App (or your primary device's Play-Fi interface) to discover and add the FW1 subwoofer to your existing Play-Fi group. Follow the on-screen instructions within the app for seamless pairing.

Wired Setup (RCA Connection)
The FW1 subwoofer can also be connected via RCA for compatibility with home cinema setups, multi-channel amplifiers, or select non-Play-Fi-compatible TVs.
- Connect an RCA cable (not included) from the audio output of your source device (e.g., receiver, TV) to the 'Sub In' RCA port on the FW1 subwoofer.
- When using a wired connection, ensure the source switch on the subwoofer's rear panel is set to 'Sub In' position.

Operating the Subwoofer
Intelligent Bass Feature
When paired wirelessly with a compatible Philips soundbar, speakers, or TV, the FW1 subwoofer automatically manages the lowest frequencies. This allows the paired components to focus on mid-range and high frequencies, resulting in a richer and more detailed overall sound profile.

Personalizing Your Sound (Wired Connection)
When connected via the 3.5mm RCA port, you can fine-tune the subwoofer's output using the dedicated knobs:
- Gain: Adjusts the overall volume level of the subwoofer.
- Crossover: Sets the frequency at which the subwoofer takes over from your main speakers. Frequencies below this point will be handled by the subwoofer.
- Phase: Adjusts the phase of the subwoofer's output relative to your main speakers, ensuring bass waves align correctly for optimal impact and clarity.
Note: When the FW1 is used as a Play-Fi subwoofer or in RF link mode, these controls and functions are not applicable as settings are managed via the app.
Multi-Room Audio System
The DTS Play-Fi compatibility allows you to expand your home theater setup. You can add additional Fidelio soundbars and satellite speakers to create a true surround sound experience. Devices can be grouped and synced to stream audio throughout multiple rooms.
