Lifetime Tech Support

OSD Audio’s WRSK250 2.4GHz Wireless Speaker and Subwoofer Kit is a great way to bring 5.1 surround sound to your family or media room without having to run speaker cables from the receiver/amp to the rear channels and powered sub. Compact and easy to install, the kit includes a transmitter and receiver that sends the audio signal from your amplifier/receiver to the rear speakers and powered sub via the 2.4GHz frequency. Now you can enjoy spine-tingling surround sound and heart-pounding bass without having to tack speaker cable around doors and along floor boards or snake cables through the walls or crawlspaces.

What Are the Advantages of Wireless 5.1 Surround Sound?
There’s nothing like watching a movie or playing a video game in 5.1 Dolby or DTS surround sound. To enjoy true 5.1 surround sound, your speaker array should include right and left front speakers to handle music and sound effects, a center channel speaker for dialog, two left and right rear speakers for surround effects and, of course, a subwoofer for bass. Connecting the front channel speakers is typically not a problem because in most home theaters the front speakers are located near the receiver/amp. The rear speakers, however, are typically located behind the listeners and the subwoofer may need to be placed in a corner or other optimal location, depending on your room’s acoustics. This means running speaker cable either along the baseboards or snaking the cables within the wall or underneath the floor, which is not always possible especially for renters. An easier and often less expensive solution is to go wireless.

How Does the OSD Audio WRSK250 2.4GHz Wireless Speaker and Subwoofer Kit Work?
The WRSK250’s transmitter connects to your home theater amp/receiver with RCA cables and plugs into a standard electrical outlet. The WRSK250’s receiver connects to the surround speakers via speaker cables (included) and to the powered subwoofer via RCA subwoofer cable (not included) and also plugs into a standard electrical outlet. The transmitter then sends the audio signal to the receiver over the air via the 2.4GHz frequency, the same reliable frequency used by cordless phones, routers and other wireless devices. Because most households have several other devices operating on the 2.4GHz frequency, the WRSK250 includes 34-selectable channels so you can dial in the most reliable and steady signal. While the 2.4GHz frequency works best line of sight, it’s not critical so you can hide the receiver/transmitter behind a sofa, inside a cabinet or even in another room. Keep in mind that while this is a wireless solution for transmitting an audio signal from a home theater system’s receiver/amp to the rear speakers and powered sub you still need to connect the speakers to the WRSK250 receiver via speaker cable.

Reliable and Backed with a 2-year Warranty
Compatible with most receivers, amplifiers and powered subwoofers with RCA inputs/outputs, the WRSK250 2.4GHz Wireless Speaker and Subwoofer Kit gives you more flexibility when designing your home theater system and relieves the stress over how to bury or hide the speaker cables. We invested a lot of time into the sound quality and integrity of our wireless rear speaker and subwoofer kit to ensure the device transmits a reliable signal with minimal latency or drops, and we back this kit with a 2-year warranty and a 30-day satisfaction guarantee.

Paul M. Buchanan • 12/17/2019, 2:17:43 PM Q Hi - I have a Yamaha Aventage RX-A840. I would like to use the WRSK250 on the Zone 2 with up to four receivers which will be wired to Nano Mirage speakers. The subwoofer connection would not be used. Also, could you give me an idea of the cost of extra receivers? Thanks for your help.

A Hi Paul: We do not sell the separate Transmitters or Receivers of the WRSK250 kit. We can offer you a special deal on bundling four kits. You would just have 3 spare Transmitters. Contact our Customer Service department. T/5355
Bob • 12/17/2019, 2:17:43 PM Q Can I use two transmitters to send audio to one receiver that powers a pair of speakers? If so, how can I order one transmitter?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Bob: I know you can have multiple Receivers connected to a single Transmitter since you would be sending the same signal to both. I am pretty sure it does not go the other way. What is your application that you need two transmitters; We only offer both our Wireless Subwoofer kit and the WRSK250 Surround Sound Kit with Subwoofer output. Ironically the WRSK250 shows two signal possibly being sent from the transmitter. It shows two options for the surround channels, one speaker level and the second from a preamp. But, it also has a Subwoofer connection from the Audio Video Receiver. The Wireless Receiver has both speaker outputs and Subwoofer preamp connection. I am trying to verify from our factory. TL/5370
Marv • 12/17/2019, 2:17:43 PM Q I have the transmitter connected to the surround speaker terminals. Both the transmitter and receiver initially have green lights on. When the music plays the transmitter light changes to blue but the receiver never changes from green and there is no sound. Is my room too big?
Customer Service • 12/17/2019, 2:17:43 PM
A HI Marv: Good question, have you tried moving them closer (maybe try extending the speaker cables) to test if the distance is an issue. If both lights are not the same. Are the speakers connected to channels 4 and 5 or 6 and 7? If you wired to channels 6 and 7 are you also using the Zone 2 connection? What AVR are you using (Make and Model). Have you gone in and adjusted the channels to make sure they are on and at the same volume levels as the other channels. Please let me know TL/5416
