Quick answer

Connect the PS Audio Wireless Transmitter for Subwoofer to your preamp or AV receiver, pair it with the subwoofer, and enjoy a clean, cable-free bass connection.

Why go wireless with your subwoofer?

Running a long RCA or speaker cable across the room is the most common headache when placing a subwoofer. A wireless transmitter lets you put the sub where it sounds best — not where the cable reaches. The trade-off is a slight increase in latency, usually under 20 ms, which is inaudible for bass frequencies. If you are a competitive gamer or need frame-perfect sync, a wired connection remains the safer choice.

What you need before you start

You need the PS Audio Wireless Transmitter for Subwoofer (SKU 39-470001), a powered subwoofer with an RCA input, and a line-level output on your preamp or receiver. The transmitter requires a USB power source (5V, 1A minimum) — most TV or stereo USB ports work, but a dedicated wall adapter is more reliable. The subwoofer itself must be within about 30 feet of the transmitter for a stable signal.

Step-by-step setup

1. Connect the transmitter to your source: Plug the transmitter into an unused line-level output on your preamp, AV receiver, or integrated amplifier. Use a standard RCA cable. If your source has no spare output, use a Y-splitter from the subwoofer output. Make sure the source is turned off when connecting to avoid a sudden loud pop.
2. Power the transmitter: Connect the transmitter to a USB power source (5V, 1A). A wall adapter is preferred over a TV USB port to avoid interference or power-down when the TV sleeps. If the transmitter's LED does not light up, try a different USB adapter or cable.
3. Connect the receiver to your subwoofer: Plug the included receiver module into the subwoofer's RCA input. If your subwoofer has both left and right inputs, use either one — the signal is mono. Secure the connection with the locking ring if provided. Do not force the RCA plug; align the grooves and turn gently to lock.
4. Pair the transmitter and receiver: Press and hold the pairing button on both the transmitter and receiver until their LEDs blink rapidly. Once paired, the LEDs turn solid. This usually takes 5–10 seconds. If pairing fails, move the transmitter and receiver closer together and retry. Thick walls or metal furniture can block the signal.
5. Set the subwoofer crossover and volume: Set the subwoofer's low-pass filter to match your main speakers (typically 80 Hz for home theater, 50–60 Hz for music). Start with the volume at 50% and adjust after listening. A common mistake is setting the crossover too high, making bass sound boomy and muddy. Lower is often cleaner.
6. Test and fine-tune: Play a bass-heavy track or test tone. Walk around the room to check for dropouts. If the sub sounds weak, increase the volume on the sub itself — not the receiver. If the signal drops, reposition the transmitter or receiver. If you hear a delay or echo, the transmitter may be too far from the sub. Move them closer or switch to a wired connection for critical use.
