This worked great on an older Pioneer from the 70's which I love to use. We could never afford one back then and now to stream to it is a joy. Thank you for spreading your knowledge. You have a very easy to understand of teaching as well Thank you again !

Thank you.

Wish I found this video before buying a new receiver.Thanks for the video

[@ambernilsson3510]

Thank you for this info! Very useful And the highlight of this video was you mentioning x-96 (listened since they began in mid 90s when. I was in jr.high) but I actually yelled out "hell ya!" Been missing X-96, SLC and even Washington. So thank you for making a music buff day on many many levels!

[@breakerbroke23]

WOW! Nice to hear I made your day. I moved back to SLC last year and found that X96 has sure changed, I found cousin Brad and the crew on 103.1 The Wave, they are playing some killer tunes. This video is a bit dated and you may want to check out this one. Bluetooth has come a long way. kzbin.info/www/bejne/bnLNi4OYe52KaJY Thanks for the kind words... Cheers my friend.

[@TheFlyingBusman]

Been there, done that. For those feeling technical it’s nice to integrate a Bluetooth module into something so it’s all internal. I have done a few items like this including a neat little technics shelf system.

[@breakerbroke23]

One of my first installations I mounted the BT module in the Stereo. Worked well but I had poor range. I took the module out and mounted it on top of my receiver.. Much better range (just a few feet, but no more cutting out when I move from room to room) Thanks for your comment....BB23

Awesome! I never knew about these devices and to hook it up like that is so easy. I'm definitely going to do this to my workshop stereo, great video sir

[@Hydrogen4Health]

Thanks for this video. I have some old KEF speakers and Yamaha receiver and I was going to give them away because I didn’t think I could connect with my new Samsung tv. Now I’ll just use your hack and skip buying a new sound bar. :)

[@breakerbroke23]

I would not use BT for what you want to do. IMO, I would take audio from your tv, and plug into an AUX or Tape input to your receiver. You will need a 3.5nn to RCA cord to do this. Plug the mini 3.5 jack to your tv's audio output and plug the male RCA's into a AUX or Tape in. Doing it this way will give you MUCH better audio.....

[@Hydrogen4Health]

WOW thanks for the help and it should be much easier.

[@Hydrogen4Health]

So I hooked up my system like you said but I do not have volume control on my TV remote. If I used BT would I gain volume control on my TV remote?

[@breakerbroke23]

Check the manual for the TV, Do you have an audio output that can be controlled. Im going to try to do what you are trying to do in the morning on my new LG 65". Both BT and audio out to my receiver.

[@aetparamedic]

What is a wall wort

[@lawrencewillard6370]

Used a head phone lead connected Bluetooth Unit. Works well and simple setup to headphones.

[@xaenon]

I did something almost identical to this with my antique (1967) Magnavox console stereo. However, my setup adds a stage to address an irritating problem I have with many portable devices - a noticeably weaker audio signal when compared to other audio sources, like a tape deck, CD player, tuner, or record player. To deal with this, I've added a TEC TC780-LC line level booster between the Bluetooth module and the AUX (tape-in) connections of the stereo. Both the Bluetooth receiver and thd line booster are powered from a switched AC outlet I wired in. Not the most elegant solution, but both the BT receiver and the line booster are installed on the back panel of the stereo, hidden from view but easily accessible. There are no permanent modifications; the external hardware can be removed and the internal modifications can be reversed easily, all in less than an hour.

[@breakerbroke23]

Yes I had a low pre out when using a few of the BT units. On My Marantz I use one of my ART pre-amps. to boost up the HK unit Iam using. Great comment.

[@charlesking4300]

I jus pulled out my ‘71 Sansui G-5700 receiver that I would love to make bluetooth. After a lil cleaning and lubing it Still sounds like new! I will employ your technique asap and report! I recently bought a gadget to make my HD TV bluetooth. It actually works two bluetooth headphones simultaneously. And, the sound is crisp, but it’s not in stereo! Hopefully your technique will accomplish that for my classic receiver as well as for my 10+ yrs Sony STR-DE197.

[@StefaanVanDamme]

Thank you for the video :) Made me look to the back of my AV. had a couple power outlets so I can connect an old phone adapter to a Bluetooth receiver with usb :)

I recently purchased an Ifi Zen blue, blue tooth DAC for $129 , not as cheap as the unit you are talking about. If you are concerned with sound Quality this unit is a good choice.

I just use those portable rechargeable bluetooth transmitters/receivers and I love them you can take them anywhere and don't need to connect any wires the one I use is by Tio Tronics or something like that, and it's great I just use the aux out to rca.

[@breakerbroke23]

If you are using the 3.5 mm headphone jack you are not getting proper signal impedance, you will get audio but not clean signal as compared to a real RCA line level.

Good video. I am glad JL came out with their own. I love JL. I have a 67 Impala and I am totally revamping the Audio system. I am running 4 amps (about a dozen speakers) NO HEAD UNIT. I am custom fab'ing a tablet into the dash and will Bluetooth all the audio from the tablet to the amps. I don't listen to FM. Like you, I am a talk radio nut. I only listen to one talk radio. The Ticket in Dallas. You should check it out. I hate radio stations on FM. No one should listen the them anymore unless you listen to talk radio. The Ticket had their own app so I will just listen to them on their app (SportDay Talk w/1310TheTIcket < you should check them out). I personally use KZbin Music and whatever that doesn't have, Amazon prime music does. The tablet will act as a streaming music/talk radio apps, video if I want to, AND since I will be using a Samsung tablet, it will have bad ass google maps app instead of crappy head unit GPS. Not to mention tablet screens are so much bigger, clearer, smoother touch screen, and simpler to wire up than a head unit. Head unit might have about a dozens wires where as a tablet is literally a power wire that will always be plugged in. the audio will be Bluetooth so no need to jack with that. Thanks for this simple video. Thumbs up!

I gave up on surround a long time ago. Not worth all the hardware and operational complexity. We use a old Technics receiver that is about 100 watts RMS per side (really low THD) in our 24'x24' sun room and it literally shakes the place with just two small Polk shelf speakers and a sub woofer in the center. So simple that even the wife can run it, LOL! We run the flatscreen, turntable, Blueray, and Xbox through it is stereo. Now, thanks to this vid, I can also add Bluetooth. LOVE IT.

Very nice, I spend a lot of time on Tunein Talk Radio too, wish there was a way to shoot the audio across the street, we're working on my Grandma's house, be nice to have something to listen to.

Iv'e hard wired the whole house & garage with speaker, phone, cable & internet. Most of the heavy lifting is done. But that 100' distance acroos the street is cramping my style. lol I'm behind the times, I'm in the Todd Rundgren & Ted Nugent camp of not having a smart phone, might change that per this video Thanks, very informative.

[@philipsmi-lenguyen8155]

All i did was got a normal cheap $3 mini bluetooth receiver with a headphone jack where plugged in a 3.5mm audio cable,the 1 with the 2 white and red rca cables on the other end in which i plugged into the Aux input on my Amp. And so i find my way much easier to do and connect. But ur way is so much more convenient tho i guess, as u wont have to keep on turning the bluetooth receiver on and off all the time when using as it's power is plugged directly to ur amp.

[@philipsmi-lenguyen8155]

Oh. Unless ur amp has a usb socket then the bluetooth receiver will also turn on and off along with the amp. If so then i'd get a bluetooth receiver and do it my way cause my way cheaper and only 5bucks with receiver and a 3.5mm audio and rca plug. The JL Audio component is bloody $100 man. What a rip off.
