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 3.9 out of 5 by 32.
Rated 5 out of 5 by from Easy wireless connection I just connected this. I plugged it into my stereo, turned it on, add it to my laptop using Bluetooth, and that's it! It works perfectly! My wife then connected from her iPhone - in seconds. This product is very simple to use, sounds good, and is relatively inexpensive. I love it!

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..

Can the BTA 10 adapter be used to connect an Onyx Studio 3 and Onyx Studio 4 to the same music source, allowing them both to be used simultaneously?

Asked by: Truitt
No. The BTA is an audio receiver which you connect to a non bluetooth speaker, which means it only receives signals from a source to act as a pseudo-bluetooth device for a non BT speaker.

Will it work on AC 220V 50 c/s?

Asked by: RoyA
The US version is only for 110V. Your local shop may sell the 220V version if you're living in a 220V area.

I have an Android MOTO Z Force and Samsung Tab A, and neither will find the BTA 10 when scanning. It paired with my lap top without a problem at 20 ft. I tried restarting both several times but still no luck. Any Ideas?

When two hk bta 10’s are within the vicinity complementing two separate systems, will a different name assignment appear to enable Bluetooth selection of the desired choice?

Asked by: Steve0BTA10102
Unfortunately, it is not possible to change the device Bluetooth name. It is not a feature which is supported by the Bluetooth receiver of the Harman/Kardon BTA-10 It may be possible if the source device permits it, with an app in a mobile phone, or a feature in a computer, may this be possible.

I already have one of these and it works perfectly. My application for it is that I have it attached to a large battery powered speaker. Can I use a portable battery like a cell phone backup as long as it kicks out 5v as a power source?

Asked by: Kevin R
Yes, as long as the battery or power bank has a current rating of 0.4 amps (400mA) or higher, it will work fine.
