Bluetooth Audio Adapter Circuit Diagram

[This review was collected as part of a promotion.] Great little Bluetooth adapter to connect to my audio system. Although my receiver has built-in Bluetooth, it is very finicky to connect to. This unit solved the problem. I like that it has an optical cable connector to make the connection to my receiver.

The Logitech Bluetooth Audio Adapter works right out of the box. It comes with a power supply , a mini-stereo to RCA cord. In my case I connected to the Aux-Input on an old Sony receiver. I paired it to my iPhone 4s and my macbook pro with no trouble. My daughter's macbook pro paired up right away but she tried to stream her iTunes and it would not go. However, her Spotify went fine. The range seemed acceptable. There were some artifacts (like digital hiccups) but I am not sure it was the device or the laptop.

Thanks cardioid diagram, I have much less outside sounds and noise.

I use the Aluratek ABC02F Universal Bluetooth Audio Receiver and Transmitter connected to the Optical Audio output on my Sony TV. It pairs with a set of Sony Bluetooth earbuds to provide a separate channel for audio for my aging ears while the TV's audio continues to function independently for the rest of the family. The optical connection to the TV was simple and the ABC02F paired quickly and easily to the Sony Earbuds. The ABC02F is plugged into a USB port on the TV and is always on so the earbuds are reconnected within the time it takes to remove them from their charger/case and insert them into the ear.

I have always had great luck with and have been very satisfied with Logitech products. This Bluetooth Audio Adapter was very easy to set up and allowed me to choose multiple audio connections - depending on the device you want to connect to (RCA or 3.5mm connections). I would recommend this device to anyone wanting to upgrade an older audio system or speakers to Bluetooth connectivity.

You may want to consider a Bluetooth adapter for your headphones rather than this. They are harder to loose and more convenient.

This worked pretty well right away, only complaint is that the dip switch diagram was less helpful than I would have liked.

Very useful adapter for laptop w/o Bluetooth. Easy to install, and works great.

would like to play songs using youtube or other audio video sources like I do with Bluetooth

I use it in a small bluetooth speaker. Amazing. Durable, large capacity for audio,
