Guest Posted October 8, 2019 Posted October 8, 2019 Hi Chaps. Does anybody out there have a solid recommendation for a high quality Bluetooth transmitter to add to my existing 2.1 setup? Ideally I'd really want something that you can feed a digital feed into, and this would need to be SPDIF via RCA as that's the only output I can provide from my setup. Alternatively line-level Analog RCA's would also be fine, but nothing with a volume control (so headphone output as the input to the BT transmitter is not an option) I don't mind spending a decent amount for a half decent setup. The inputs of SPDIF RCA or analogue line level RCA's are where I'm coming unstuck. Thanks fellas.
warweary Posted October 8, 2019 Posted October 8, 2019 Does this one suit? https://www.cablechick.com.au/cables/advanced-digital-to-analogue-audio-converter-bluetooth-50-receiver-with-volume-control.html?imt=1&gclid=EAIaIQobChMIxtz26M-M5QIVQQwrCh1kDwmqEAQYBCABEgJ_c_D_BwE I havent used it but it does have digital in rca.

Cheers mate but that's a receiver, I need a transmitter to connect BT headphones to my 2.1 setup.
Neo Posted October 8, 2019 Posted October 8, 2019 (edited) This should be on top of shortlist, will do optical as digital input and also analog but in 3.5mm. So will require a 3.5mm to 2 rca analog cable. See picture attached prices are in US dollars, but would ring Minidisc and ask for prices Also if you keen on using coax out of your dac then this might also be of interest as another option https://www.minidisc.com.au/fiio-d03k-coaxial-optical-to-r-l-audio-converter https://www.minidisc.com.au/sennheiser-bt-t100-bluetooth-audio-transmitter Neo Edited October 8, 2019 by Neo
Guest Posted October 8, 2019 Posted October 8, 2019 Thanks Neo I was hoping to not have to convert. Was really after a single device. The preamp I have can output line level RCA or balanced - or I can pickup from my digital recorder via Coaxial SPDIF. No Toslink, sadly. BT input is easy done it seems, loads of options there. BT output not quite so easy.
Neo Posted October 8, 2019 Posted October 8, 2019 (edited) If not keen on conversion with Fiio then the Sennheiser unit will be ideal with analog 3.5mm input. Give a call to Minidisc and speak to Wing, he will be able to discus further but like you said the choices are very limited to connect your BT headphones with a quality transmitter I did explore that option not too long ago and when discussing with Wing he said it’s a very popular device that they sell. I didn’t go ahead as I prefer old school setup with my headphones with a wired connection and the BT headphones were given to a family member who use them in portable duties.

gt1482 Posted October 9, 2019 Posted October 9, 2019 I am not familiar with BT transmitters, but I suspect the quality of the transmitter is not very important here, especially if a digital input is used. All bluetooth protocols are lossy. The transmitter has to compress/downsample the input before sending it over. You will be listening to the DAC/amp inside your BT headphones regardless of what device sends the data to them. I think it is more important to make sure that the transmitter can support the best BT protocol supported by your headphones. If it is for video applications, latency (lag between video and audio) will also be a concern. Just wondering what the source is. If the source is already in digital format, likely there is a way to just play it from your mobile phone/tablet/computer which can already transmit BT.

Well that's the issue. I do want to use a digital source, however my gear can only provide RCA SPDIF and not Toslink which is what most of the BT transmitters use and I'd really prefer to not have to use a converter. 39 minutes ago, gt1482 said: Just wondering what the source is. If the source is already in digital format, likely there is a way to just play it from your mobile phone/tablet/computer which can already transmit BT. Vinyl records, going through a valve preamp then onto a Tascam digital recorder (that can provide both line level RCA analogue and RCA SPDIF digital). Once you introduce headphone jack inputs from line level RCA's you're then dealing with other problems. Ahh it's OK I'll just wear my wired headphones, sod it.
gt1482 Posted October 9, 2019 Posted October 9, 2019 It is converted to digital by the digital recorder already. Why not simply save the digital copy and play it on a phone/table/computer if you want to use BT headphones? And you will never need to spin the same record again just for listening through BT. You wouldn't get true analog sound from the vinyl anyway with BT in the middle.
