Combines In-wall Volume Control with the Convenience of Bluetooth® 
OSD Audio’s Bluetooth'-ready in-wall volume control with amplification lets you control the volume of your whole house audio system or home theater without the need of a separate amplifier or receiver.This simple-to-install volume control includes a Bluetooth receiver and a separate amplifier so you can manage the volume of your entertainment through your cellphone, tablet or computer.

Built-in Amplification 
Unlike traditional in-wall volume controls which must be connected to a separate amplifier, the XWB50 includes a 50W (2 X25 RMS @4ohms) amplifier.This means power is built into the system so you can enjoy clear, crisp and powerful audio without having to connect to an amp. The XWB50’s Bluetooth®  receiver also has a wireless range up to 32.8 feet (10m) to control volume from various areas of the room.

More than a Volume Control 
Ideal for whole-house audio, media rooms and home theaters, this truly unique powered in-wall volume control includes 3.5mm aux input to connect to your cellphone or other device directly, which is a handy feature for those times when Bluetooth' is not available or a bit sketchy.The Decora-style plate can be mounted anywhere close to a standard outlet, and the amplifier mounts in the wall as well and can be installed out of sight near the outlet. All connecting cables, power supply and power cord is included so there will be no last-minute trips to the hardware store.Designed with precision electronics to provide low distortion and a flat frequency response, the XWB50 installs easily and works with virtually any audio system, and you don’t need to be an electrician or even that handy to install the unit and start filling your room with the music you love.

13 Questions asked on In-Wall 50W Amplifier with Bluetooth®/ 3.5mm Aux Input, Decora-Style Rotary Knob & Plates - XWB50

Tim Hodder • 12/17/2019, 2:17:43 PM Q Can this device be hard wired in to power??
Customer Service • 12/17/2019, 2:17:43 PM
A HI Tim: It already has a built in amplifier that connects thru Bluetooth and also a pre amp 3.5mm connection on the plate featuring the power connection for the external wall wart. You could add a SVC 405 Impedance matching Volume Control featuring an A/B switch so you could add another source. The beauty to this in wall amplifier is you can add any pair or even two pair of speakers to the internal amplifier with master volume control. Pretty cool TL/4631
Mark • 12/17/2019, 2:17:43 PM Q Can multiple units be used in the same house at the same time?
Customer Service • 12/17/2019, 2:17:43 PM
A HI Mark: You can do multiple units in your house but most devices only allow you to sync up with one Bluetooth Receiver at a time. I believe there is anew app on the new SAMSUNG Galaxy phones that allow you to connect to two Receivers at a time. You also have the ability of driving speakers in two rooms. The internal amplifier will drive two 8 ohm speaker in parallel so you could run a pair per two rooms or two pair in the same room. Stay tuned new connectivity options are evolving as we speak. TL/4662
Alex • 12/17/2019, 2:17:43 PM Q Hi, Can I connect ASUS Xonar Essence STX audio card by using bundled RCA-to3.5 mm Y cable to ZWB50 amplifier and AP840 Outdoor Patio Speakers? If not, what would you recommend for instead? Please advise. Best regards, Alex
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Alex: The ZWB50 has a built in Bluetooth Receiver and 25 Watt Class D 4-8 ohm amplifier. There is a second plate that includes connections both for the external wall wart/power supply and 3.5mm stereo audio cable. I should work with any device that connects with an aux cable most smartphones with a headphone jack. TL/4769
Joe • 12/17/2019, 2:17:43 PM Q I own the BTP525 speakers, and they are great, mounted outside on my patio. Currently I also have a tv outside with a 3.5mm adapter to bluetooth transmitter to transmit to the speakers. It works, but the tv is mounted high and if i want to switch between the tv to bluetooth speakers to a phone/ speakers, i have to get up on a ladder to disconnect, etc. I was wondering with this product, if i can mount this volume control plate next to the tv at a normal height, run the power & 3.5mm to the new wall plate will it transmit bluetooth to the speakers and use the volume control knob to control the volume?
Customer Service • 12/17/2019, 2:17:43 PM
A HI Joe: The wall unit will work as you described, it will not sync up with the current speakers you have unless you have one of the new android phones that will connect to two Transmitters at once. The real advantage of the XWB50 is that you can connect it to two pair of passive speakers as long as they are 8 ohm and when run in parallel they show a 4 ohm load which the internal amplifier will handle. I have recommended a number of these units in our upload your plans where we use it in a pair of speakers in a bedroom and connecting a second pair or single DVC speaker for the attached bathroom. The unit has two inputs, one being the Bluetooth and the second an hard wired aux cable input (3.5mm). But suggest they add a SVC205 Volume Control which features an on/off switch. You then have a choice of Bluetooth or connecting the local television either directly from the TV or local cable box. Top that off with a pair of angled speakers to be placed closer to the adjacent wall where the TV would be mounted. Creating a night and day difference while listening to the TV audio through the XWB50 and the pair of angled effects speakers. TL/4813
Lance Ridgely • 12/17/2019, 2:17:43 PM Q With multiple installations in my home, connecting to the right location could be problematic. Is there a way to rename the device so I can tell what room I'm connecting to?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Lance: I tried this on my Android phone and have renamed the device. This is the link where I found the answer... Unpair, rename, or pick actions for a Bluetooth accessory 1) Open your phone or tablet's Settings app Settings app. 2) Tap Connected devices and then Bluetooth. 3) Make sure Bluetooth is turned on. 4) Next, to the paired accessory, you'd like to change, tap Settings. 5) Change the accessory's name, disconnect, pick actions ("profiles"), or unpair ("forget") the accessory. We are testing the iPhone at work to see if we can get the same results. TL/5122
