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.

Does this unit have a pause/play/skip functionality? Also does the volume knob also power on/off?

Hi Gary:

The functions you refer to are controlled on whatever Bluetooth enabled device you are using. The. The Volume knob adds additional gain to your device plus when you turn the knob all the way counterclockwise it clicks off. So in answer to your second question, you can turn the amp/Bluetooth Receiver on and off with the front rotary knob.

When using this in multiple zone i.e master room, foyer, study,

can the respective BLUETOOTH NAMES be customized to fit the respective zones.


Russound's BTA decora style allows one to go in via USB and download the bluetooth naming KIT to rename any including changing the password.


Please advice

Hi UOA:


There is no programming the chipset. As stated before, you can change the name on an Android device, but that change will only show up on the Smartphone or Tablet where you changed the name.

if put in multiple locations, can each respective bluetooth have their customized names?


1 Answer
Hi UOA:


I do not believe you can change the name of the XWB50. You can change the name on an android device for each unit, but each device would have to program with the dedicated name you picked. The internal chip can not be changed. We are developing another in-wall docking station this one for the ALEXA Echo Dot Gen3, which we are calling the NERO VOX due in at the end of October. You will be able to change the name and also be able to group any combination of the GEN3. It will be voice-activated, touch-controlled, or controlled by the ALEXA app. You can also select the Gen3 in the streaming music app Spotify.

from Maryland asked:
September 26, 2019
A number of simple (I hope) questions that I can't quite make out from the Q&A (thanks for these...they're great, if not a bit over my head technically):

Looking for a simple way to connect a TV and music from a mobile or tablet to ceiling speakers in a small room.  I don't have space for a stand-alone amp, so this is really appealing.  

1. If the TV has built-in bluetooth (or an adapter), my assumption is that I can switch between the two bluetooth sources automatically by pairing via phone/tv (it can only pair with one device at a time.).

2. If I use the 3.5mm plug to connect the TV audio, does that override the bluetooth?  If I wanted to stream content from a phone, I'd have to manually pull that jack out, correct?

3. My assumption is that the volume on the device is not fixed.  Therefore, if we wanted to raise or lower the volume, we could adjust the knob or raise it on the source device.  Is that right?

4. Is there a way to hard-wire this, or is the best aesthetic application to mount the DC power input behind the TV and next to the power for the TV so it's unseen?

5. Am I overthinking this?  Is there an easier way to do what I'm trying to do--send sound from either a TV or mobile device (without going through the TV) to in-ceiling speakers without adding an amp?


Thanks again for your help.  Love your site and your support!

Hi Spencer:


The XWB50 is a product that would work for the application you described. But, check out our new NERO Stream XD which is a small Integrated Amplifier that includes wall mounted brackets so it can mount behind your TV. The NERO Strean XD features an Audiophile 16/24 bit 192kHz DAC; Digital to Analog Converter. It also features Streaming Wi-Fi (controlled by our free OSD Play App) and Bluetooth as well as Analog in and the aforementioned Digital Fiber Optic. The inputs are selectable using the IR Remote control that comes with the Integrated Power Amp. It also features a Subwoofer output allowing you to add a Power Subwoofer. I would like to help you design and wire your system tim@osdaudio.com

Note: We will also have an in-wall docking station for an AMAZON ECHO Dot Gen 3 streaming device with a preamp input as well like the XWB50.

JP
from Canada asked:
November 18, 2018
Just to be clear - is the CAT-5 connection between the two plates for the 3.5mm AUX input, or is it for the 24V power? It's hard to tell from the documentation and the photos. I am considering using these units in several rooms, and using a 24V / 2A power distribution box in a central location to feed them power instead of using the included power supplies to minimize the in-room clutter, and need to know what kind of wiring is needed for the power connection to the XWB50. Thanks in advance for your time in replying!
1 Answer
Hi JP: You are correct the network or Cat5 cable is the hook up for the 3.5m Aux input line. You can use a 14-2 Romex cable to run DC 24 volts power to the XWB50. It should work perfectly. Please let me know how it works, tim@osdaudio.com. Good luck TL/5289

William Johnson
from Bedford, Va asked:
October 7, 2018
Purchased the XWB50 and a pair of 6.5" speakers. May be a simple question but is it possible to buy a second set of speakers and run them through the iss4 speaker selector and switch back and forth between two locations.
1 Answer
Hi William: The XWB50, rated at 4/8 ohms, can drive two pairs of 8-ohm speakers at once (4-ohm load). The ISS4 can easily be added to organize the two pair of speakers you are proposing. Both pairs of speakers can be played at once (without the protection switch being enabled, turned on). If you add a third and even fourth set, you would need the internal protection turned on.

I have 4 rooms with 2 speakers each, 8 ohm. Would I need one of these for each set, and can they be programed with my I-Phone separately? If I need 4, no prob. But can they run different music at the same time? Thanks, Chas
2 Answers
Hi Charles: You would need an XWB50 for each room. Each one would sync with a different Bluetooth enabled device or has a second source input that can be hard-wired with a 3.5mm auxiliary cable. Each XWB50 would appear under the same name "Bluetooth" on your Bluetooth enabled device. So you would show up to four speakers labeled Bluetooth. Android will allow you to rename a Bluetooth speaker on the device you are connecting with the XWB50. Once one device connected with one of the Bluetooth Receivers, it would be unavailable until it is un-synced. I do not believe the Apple iPhone will allow you to rename the speaker but the speaker may show up in your list in the same order it was added as you on your search list. You could connect up all four devices with four different Bluetooth enabled devices and play something different on all. I have heard that some of the new Samsung Galaxy9 phones will allow you to connect to two receivers at once. These XWB50 Receivers feature an amplifier rated at 4 ohms so you can connect two pairs of 8-ohm speakers in parallel. As an example, this allows you to add another pair of speakers in an attached bathroom. I have designed a system for this application where I added our SVC205 volume control with on/off switch on the front of the VC. You would have the same music as the Bedroom but have local control to turn the music down or shut it off with the front rocker switch. You also have the option of plugging in an aux/RCA cable connected to a TV in the bedroom as the second source. Check out our angled speakers like our 6.5" ACE670 for more installation options. I am sure someone is working on a third party app to let your iPhone rename the Bluetooth Speaker. Good luck TL/5153

Lance Ridgely
from IA asked:
July 23, 2018
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?
1 Answer
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

February 23, 2018
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?
1 Answer
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

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
1 Answer
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

Can multiple units be used in the same house at the same time?
1 Answer
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.

Can this device be hard wired in to power??
1 Answer
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
