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.

Other Product Info

Place the transmitter and receiver within 100ft each other, on a flat surface or mounted on a wall.
1. With the audio source off, connect the transmitter to the speaker and subwoofer jack with the RCA cable and speaker wire.
2. Connect the supplied AC adapter (9V, 200mA) to the transmitter DC IN 9V jack, and then plug it into a standard household outlet.
3. Connect the receiver to your speaker and subwoofer with the RCA cable and speaker wire.
4. Connect the supplied AC adapter (9V, 200 mA) to the receiver DC In 9V jack, and then plug it into a standard household outlet.


When you connect the power and signal cable, the transmitter and the receiver LED's light green. If there's active audio source, the receiver automatically activate and send the signal to subwoofer input.


If you experience any interference, press and hold the "M" button on both transmitter and receiver units, both units will automatically change the channel and link.

Note: The wireless subwoofer kit will enter into standby mode 17 minutes after there's no signal.

from Oregon asked:
February 17, 2019
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?
1 Answer
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 tim@osdaudio.com. TL/5416

January 12, 2019
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?
1 Answer
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; tim@osdaudio.com? 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

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.
1 Answer
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 tim@osdaudio.com

Michael P Batkiewicz
from MN asked:
December 14, 2018
How can you call it wireless when there is more wires than just the one it takes to plug it into the the back of an AVR. Let me count 2 ac plug ins where are you going to find them in the middle of your back yard and then you have to wire the speakers to them and then there is water proofing. What a joke. I would spend the money on high quality speaker wire and spend the 1 minute to hook up.
1 Answer
Hi Michael: This kit is for Rear Channel Surround Sound Speakers. It is for applications where there is a problem running speaker wires to your rear surround speakers. It has a two channel 25 watt amplifier built-in. You still have to run speaker wire from the back of the receiver to the speakers themselves. It has a subwoofer output as well in case you have a problem running a signal cable to a rear or second subwoofer location. There is no reference to any outdoor application, only to walls, and crawl spaces. Sorry for the confusion. TL/5333

November 19, 2018
Hello, I want to setup multiple wireless surround speakers from my 5.1.4 channel receiver (Dolby Atmos setup), how many of these wireless amp kit can I use to replace my wired surround back channels (two stereo/four speakers total)? Thanks for the answer.
1 Answer
Hi Sam Bee: If you have four dedicated channels you want to connect to you will need two kits. You can connect either at speaker level output or preamp depending on what outputs you have available on your Audio Video Receiver. You can also connect a second powered subwoofer if need be connecting to the preamp output of the AVR to the RCA Sub input on one of the Transmitters and then connect to the output RCA of one of the Receivers. Then you would have a 5.2.4 system. Please let me know more about your home theater, I would be curious if these will work for your setup. tim@osdaudio.com. TL/5291

dale cole
from Winston Salem NC asked:
August 7, 2018
Can this be used to transmit from a non powered mixer to powered speakers to make them wireless? Without a delay . Can this be used by a band to transmit from a mixer to the PA speakers?
1 Answer
Hi Dale: You will need to check the connection from your passive mixer. Check to see if it has RCA Stereo preamp connection (right and left, plus and minus). There may also be 1/4" or even XLR where you can find both 1/4" to RCA or XLR to RCA. That would be needed to connect to the Transmitter. There is also an RCA Stereo Preamp output on the Receiver side as well by-passing the internal 25-watt amplifier. You have left and right RCA stereo output from the Transmitter. So it depends on your PA speaker inputs. You also have a preamp subwoofer output as well on the Receiver. I have not heard of any issue with latency. You have 30 days to try it out, just save the packaging in case you need to return if it does not perform to your satisfaction. 30-day Satisfaction Guarantee. TL/5150

Randy
from Ironton, OH asked:
May 22, 2018
Can this be used just to put a speaker into another room from an amplifier instead of running wire to the speaker? Basically to make the external speaker wireless, rather than hard wired?
1 Answer
Hi Randy: There is no restriction on what output you can connect with whether it is the rear surround channels of a custom home theater or connected to a zone 2 preamp out. The 2.4 GHz is RF, not IR so the line of sight is not critical. You can also add a subwoofer to go with it as well. Good choice TL/5000

What are the specs of the amplifier in the receiver unit? Watts, THD, etc.
1 Answer
Hi Fish: The unit is rated at a strong 25 Watts with no more than 1% THD (total harmonic distortion). Ideal for surround speakers or just 2 channels where you have a problem running any wires between the audio source and amplifier. TL/ 4794

Can I use this device where the location of the "base unit" is in one room, downstairs and the"receiving" unit, in another room upstairs?
1 Answer
Hi Chris: Absolutely, this is 2.4 ghz wireless RF. It does not need a line of site like IR to connect. There are multiple channels to choose from to find the best that will work. You have a choice of inputs to the Transmitter either Speaker Level pre amp output. Lots of flexibility. TL/4661

Ell
from Middletown, CT asked:
October 24, 2017
I own (and love!) my WRSK50. If I buy another one to use in a room directly below the current one will they interfere with each other?
1 Answer
Hi Ell: You should not have a problem, this is from the web page for the WRSK50: 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. So you can dial in different frequency channels and connect without interfering with your first unit. TL/4604

Will these units work on 240 volts.
1 Answer
Hi Joshua: The Receiver has a power Supply that is Multi Voltage 110V/240V. The Transmitter has a 9V AC adaptor that is no (120V/60Hz). I am assuming you can purchase a Universal 9V power supply in New Zealand that will be Multi Voltage. That should work. TL/4439
