Frequently Asked Questions - AirShip II Wireless REL Acoustics
How do I pair the AirShip II Wireless Receiver with the transmitter?
To pair, press and hold the Pairing button on both the transmitter and receiver until the LED indicators flash rapidly. Once paired, the LED will become solid. Keep devices within 3 feet during pairing.
What is the maximum wireless range?
The maximum range is up to 65 feet (20 meters) in open air with line of sight. Walls and obstacles may reduce range. For best performance, avoid placing the receiver inside metal cabinets.
Can I use the AirShip II Wireless Receiver with other brands of subwoofers?
The receiver is optimized for REL subwoofers and includes a dedicated output. It may work with other subwoofers via RCA or XLR, but compatibility is not guaranteed. Check the input requirements of your subwoofer.
How do I connect the receiver to my subwoofer?
Connect the subwoofer to the receiver using RCA or XLR cables. Ensure the receiver's output matches the subwoofer's input. Use the volume control on the receiver to adjust signal level.
Does the AirShip II Wireless support multiple subwoofers?
Each receiver supports one subwoofer. To use multiple subwoofers, you need additional receivers (one per subwoofer) and a transmitter that can pair with multiple receivers (check transmitter model).
What should I do if the audio signal drops or crackles?
Check for interference from other wireless devices (WiFi routers, Bluetooth). Move the transmitter and receiver closer together or away from metal objects. Try changing the channel if available, or re-pair the devices.
Can I use the receiver with a REL HT/Subwoofer that has a wired connection?
Yes, the receiver can replace a wired connection. Simply connect the receiver's output to the subwoofer's input. Set the subwoofer's volume to 50% and adjust using the receiver's volume control.
How do I perform a factory reset?
To reset, press and hold the Pairing button for 10 seconds until the LED blinks rapidly three times. The receiver will restart and lose all paired connections. Re-pair with the transmitter.
What type of power supply does the receiver use?
It uses an external AC adapter (100-240V, 50/60Hz) with a barrel connector. Use only the supplied adapter to avoid damage. If lost, contact REL for a replacement.
Is there a noticeable delay in the wireless transmission?
The AirShip II Wireless uses low-latency technology with a delay of less than 16ms, which is imperceptible for most listeners. It is suitable for movie and music playback.
