Common questions about manuals, registration, and support for this brand.
Power on both units. Hold the pairing button on the AT4 transmitter until it flashes rapidly. Immediately press and hold the pairing button on the Speedwoofer for 3 to 5 seconds. The light on the transmitter should display solid blue when paired.
No. The wireless transmitter uses radio frequencies designed to work around furniture, but solid barriers like walls, floors, or heavy cabinet doors can block or severely degrade the wireless signal.
To fix dropouts, reduce physical obstacles between the transmitter and receiver, move the units away from other Wi-Fi devices to reduce interference, or reposition the transmitter using a longer RCA cable to establish an optimal line of sight.
You can connect up to four compatible AR4 wireless receivers or Speedwoofers to a single AT4 wireless transmitter simultaneously.
