## Questions & Answers

**Q: Do you have to switch this on each time that you use it, even though it has a power supply? I.e. does it switch off automatically?**
A: In my case I needed it to be able to use my Bluetooth headset to listen with out disturbing anyone else, so all I did was plug it into the same power source as my TV so that it is ready to be used any time the TV is on. I hope that is useful information for you. 👍

**Q: Would a couple of these act as a bluetooth pass-through bridge between an analog line output (5.1 decoder) and an analog  line input? (amped speakers)**
A: Dear Customer,
Thank you for your question! There is no problem with this operation, but our BT-B22 does not support 5.1, and if the audio you transmit is Dolby audio, we also do not support it. We only support stereo. If you have any questions, you can send a message to our customer service email: jgzh2017-us@hotmail.com

**Q: Can you use this during gaming to talk to other players online /via video speech like Skype? ~ie simultaneously broadcast and receive Bluetooth input?**
A: Dear Customer,
Thank you for your question! Our Bluetooth adapter BT-B22 does not have a microphone, so voice chat is not possible. However, we have another adapter B26 for voice chat, you can search for ASIN Code: B07QL6RSC4 for purchase. If you have other questions, you can send a message to our customer service email: jgzh2017-us@hotmail.com

**Q: Using as receiver, the optical out works to connect my sound speakers? (It have optical in)**
A: Dear Marcio Ederson,
Thanks for your question!
When our BT-B22 adapter works as a receiver, you need to plug the optical cable into BT-B22's RX Output port and your speaker's input. And then pair it with your phone/tablet.
If there is any other question, pleas send a message to our customer service email: jgzh2017-uk@hotmail.com

Great little box of tricks, which I bought to replace a set of earphones to help with hearing difficulties. Does exactly what I need and at a great price.

### ⭐⭐⭐⭐ Works well, easy to use
*by D***R on 27 September 2022*

I'm only using this as a Bluetooth transmitter to some Jabra earbus via the optical output of a SKY Q Minibox and the AUX (stereo min-jack) output of a desktop computer. It's pretty easy to set up and pair, and the controls are very simple - On/Off, volume +/-, pair, and switch between optical and AUX. Once paired, connection is automatic and a status indicator light at the front shows what's happening. It comes with a full complement of cables and a tiny but detailed printed instruction manual, which even has specific instructions for use with hearing aids, Amazon Echo, Google Home devices, and Airpods. Given a decent cable, the AUX input sound is crisp & clear, and the optical input sound is very good (48KHz, 24 bit). My earbuds don't have the aptX low-latency Bluetooth codec, so the default SBC codec is used - this gives a noticeable (~220ms) lag between vision and sound, but I think it's OK unless you're gaming. For gaming, aptX Bluetooth headphones are a must. This device looks almost identical to the Avantree TC417 which costs £5 more and has the same layout, functions & features, so I suspect they use the same electronics. The only significant difference I can see is that the Giveet comes in a plain box and support is via email, whereas the Avantree comes in a glossy printed retail pack and has website support. So far, so good.
