Wirelessly stream audio to any entertainment system.

Sometimes you want your favorite music to fill the room, not just your headphones. And if your home entertainment system already has Bluetooth® capability, you can wirelessly stream audio from a portable device (for instance, your smartphone or tablet). But what if your system isn’t equipped with Bluetooth technology? Not a problem. The Harman Kardon® BTA 10 external Bluetooth adapter connects directly to your entertainment system and enables you to stream audio wirelessly into the system from any Bluetooth-equipped portable device. The BTA 10’s HARMAN TrueStream™ technology means that its wireless audio connection to your entertainment system will be the highest quality possible – no matter what source device is supplying the audio. For your convenience, the BTA 10 has an LED indicator light that blinks as it searches for your Bluetooth-equipped device and stays steadily lit when it’s paired up successfully. The BTA 10 even comes with cables so that you can hook it up to your entertainment system. From home systems to portable speakers to speaker docks, the BTA 10 Bluetooth adapter adds wireless streaming capability to any audio system with a stereo 3.5mm aux input or stereo RCA inputs.

BTA 10 is rated 4.2 out of 5 by 27.
Rated 5 out of 5 by from Great Bluetooth Device It's compact, has great sound and the right connections for my stereo... Just what I was looking for

Rated 5 out of 5 by from wonderful unit Quality of sound is pretty good. Even though the set up was straight forward, it would help to have a few line of instructions in the manual.

Rated 5 out of 5 by from Small, Simple, turns anythng to Bluetooth device I've personally purchased twenty or more of the BTA-10's over time.. at least ten are active around the house and in my (older) cars. Family have the rest.. and love them too. BTA-10 is simple, small and does just what it's supposed to do.. bring older tech devices into the Bluetooth world. My only gripe, and it's in NO way a game changer... to date we cant change the SSID broadcast name.. it's always BTA-10.. so when you have more than one in the same vicinity it might be a bit confusing which to connect to. Most modern BT devices allow re-naming the BTA-10 their connecting to.. i.e. Kitchen, Den, Car1, etc.. but the SSID cant change .. yet :) GREAT DEVICE..

Rated 5 out of 5 by from Very simple to hook-up & operate I am very happy with this product: simple to use and easy no reading through endless instructions. You simply hook-up power & input, go on your Bluetooth phone and its' there! No guessing...

Can one use two of these close to each other for output to two different earbuds? We want to connect two of these to the audio out of two camcorders to monitor the audio wireless while filming. Each cameraman will have his own set of Bluetooth earbuds.

Is there a power on/off button? or does it turn on/off automatically when power supply is connected/disconnected?  Is the power input connection USB mini or USB micro?

Asked by: SBL1
The BTA 10 does not have a built in power switch. It will turn off once the USB Mini-B 2.0 power supply is disconnected.

My iphones, iPad,and ipod touch cannot see the device. It does not show up. When the device is attached to power it has a blue light that slowly flashes and eventually goes dark. Is the device defective or is there something I am missing? thanks

Can I pair more than one set of headphones with the BTA ? If so, then how many sets?

Asked by: Thomas R
The BTA 10 is a bluetooth receiver like the bluetooth headphones so you can't connect the headphones to the BTA 10 together.

Can I attach this device to my stereo receiver and then pair bluetooth speakers to it so I can play the stereo in another room?

Asked by: soccermom
Yes you can. You can use the Audio out from the BTA 10 and connect it to your receiver using the Aux cable so your receiver can play the music from the BTA 10.

I was using the HK BTA 10 with a Bose sound dock. It quit working. The computer (Windows 7) appears to see the device fine, though I did uninstall and re-install the device just to be sure. It works from my cellphone.

Asked by: MattL
For the record, I had to remove all the BT stuff from the Device Manager, including an entry for "Other Devices->Bluetooth Peripheral Device", then reinstall drivers using a utility I found for my laptop on the Lenovo site. That may have been overkill, but it worked. I tried just removing the Device from Devices and Printers and re-installting, but that was not enough. You may be having a similar problem if you see the following: 1. As mentioned earlier, it works with other devices. 2. If you go to the entry for the HK BTA 10 in Devices and Printers, open it, click on "Listen to Music" and nothing happens (that is, not bluetooth connection messages).
