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.

Rated 5 out of 5 by from Extended the life of my old "Play and Go" I had bought a Harmon Kardon Play and Go about 5 years ago because I was so impressed with the beautiful sound . . . the blue tooth makes it much more practical to play my music from my telephone bluetooth and the quality of sound is still great! Thanks for asking. Peace.

In other words can this transmitter link the two speakers to play from one device at the same time.

Asked by: KjWill
Unfortunately, this would not be able to connect 2 speakers. The BTA-10 is a Bluetooth receiver not a transmitter.

I want to blue tooth from my bose reciever to my blue tooth bose head set. Will this work?

Asked by: Barry
Yes you can have this connected to your receiver and you can use the BTA 10 for playing music wirelessly through any Bluetooth device. However the BTA 10 is just a receiver and won’t be able to transmit the audio to the headphone.

Does the BTA 10 connect to my non Bluetooth tv audio out and broadcast the tv audio to a Bluetooth speaker?

Asked by: JimR
Unfortunately, no. The BTA 10 relays audio signal that it receives from a Bluetooth device(i.e. Smartphones, laptops, Etc...) to a non-Bluetooth capable device. As shown in the Quick start guide, you need to connect the BTA 10 via the Audio out port at the back to a non-Bluetooth capable device.

hello is this external Bluetooth adapter compatible with your harman/kardon avr 354 receiver? thanks

Asked by: dylon
Yes, the BTA-10 is compatible with our AVR354. Just use the 3.5mm AUX to RCA cable that came with the adapter. Connect the 3.5mm AUX jack to the BTA-10 then the RCA jack to the L/R analog(RCA) IN port of the AVR.

My tablet use to connect to my BTA 10.now it will not. I am able to connect m tablet to a Bose wireless speaker. What happened?

Asked by: David1113
Please unpair/forget the BTA10 from your tablet. Then shut the tablet down, completely OFF. Then boot the tablet back up and completely shut it down a second time. This will allow the tablet to go through an entire on/off cycle without ever seeing the BTA10, removing any remnants of the BTA10 connection. Now boot the tablet up one more time and pair it with the BTA10 again. This will likely fix the issue. If this doesn't help, please submit a request at www.harmankardon.com/contactus and the Customer Service team will be more than happy to further assist you.
