Add Bluetooth to A/V Receiver Amplifier Within 3 Minutes





Introduction: Add Bluetooth to A/V Receiver Amplifier Within 3 Minutes

This is a very simple upgrade that you can do to any amplifier that does not have Bluetooth built in. In my case I will be adding Bluetooth to my Home A/V receiver amplifier. It only takes about 3 minutes and is completely removable should you decide to change your setup in the future.

Step 1: Parts List

1. USB Bluetooth receiver ($3 to $10 Ebay or Amazon (I recommend getting one that has V4.1+EDR its gonna give you better sound quality)

2. USB Charger ($1) Ebay or Amazon

3. RCA to 3.5 mm audio cable ($2) Ebay or Amazon

4. Audio Video stereo receiver amplifier ( or any amplifier with RCA input )

Step 2: Making Connections

Start by finding a unused RCA input on the back of the A/V receiver that you could use for Bluetooth. If all are being used it is possible to use the auxiliary input on the front of the unit, however you will likely need a different cable for that. I choose the CD to use as my Bluetooth input and plugged the RCA cable into it and on the other side connected it to the USB Bluetooth adapter. Next plug the USB Bluetooth adapter into the USB charger and plug it into an outlet. Its a good idea to plug the A/V receiver and USB charger into the same switched surge strip so you can flip power on or off to both at the same time.

Step 3: Pairing

All that's left is the pairing of the Bluetooth adapter with with any streaming device that you prefer. I used my cell phone which happens to be android but even with apple devices the setup is about the same. Simply go into your phone settings and turn on Bluetooth and it will automatically scan for any Bluetooth devices within range. (Bluetooth has a range of around 30 feet) The Model of the Bluetooth adapter should show up under available devices. (mine showed up as EC502) Once your device finds it just click on it and it should move to paired devices and also say connected next to it. If your A/V receiver is on you will hear a pairing sound from the speakers which means your have successfully paired your device to the A/V receiver. Congratulations your all done! enjoy your tunes via Bluetooth on that A/V receiver amplifier.

    you have to use a Bluetooth audio receiver module and that will have a 3.5mm jack on it .. there are hundreds to choose from on eBay and Amazon

    I have a Sansui AU-11000 amplifier built in 1974/75. You would spend thousands of dollars now days to get the same quality of sound.The 1970s and 80s are considered the golden age of sound.Its when they made amplifiers to last.Checkout or to restore these Museum peices.

    oh yeah. good ole Sansui. I had friends that came back from Viet Nam with them. They were great. so were the speakers. Side note: they would pack the boxes with "candy" from Nam and Thailand. It was very tasty! :-)

    totally agree with you on that rooster .. they certainly don't make them like they used to.

    Thats for sure! I asked for a service manual for a Digitech amplifier I was checking out in an electronics store a while ago. They said they dont have service manuals anymore? If that doesnt say built in obsolesence I dont know what does? I refuse to buy anything that doesnt have a service manual anymore because it would invairiably be plastic junk that fails just after the warranty runs out. lol

    I picked up an '87 Nakamichi Stasis SR-4a receiver a few years ago for $125 and it's definitely a favourite of mine, compared to my Denon and Onkyo home theatre receivers. I set up my bluetooth exactly the same as this 'ible and it works great when I want to listen to some "current" music that I don't have on vinyl. Or if I'm too lazy to get up and flip my LP's.

    If I had known it was this easy, I would've had Bluetooth long ago. I'm going to Ebay right now to order my parts. Thank you very much, Imran687!

    So the rca plugs into the back of the radio (we can see that), but where does the audio jack end of the rca plugs to? The Bluetooth device? (Thanks)

    1 reply

    yes the other end (3.5mm plug) goes into the 3.5mm jack on the Bluetooth adapter

    should work as long as your device has a Bluetooth..tablets, smart phones.

    I did something similar to give new life to an old Magnavox console stereo. I can listen to MP3s and internet radio on something that was built decades before either of those things was even conceived, and it sounds wonderful.

    Are you living in a museum ?

    Some might say I am a museum piece myself. Bear in mind that not everything 'old' is 'junk'. You might be amazed at how good those old consoles sounded, particularly the 'big' names like Magnavox, Zenith, RCA, Motorola, Grundig. These were the premium sound systems of their day, often costing the equivalent of two or even three thousand dollars in today's prices, and it's remarkable how well they hold up. They're elegant and stylish (okay, 'stylish' is subjective, but still) and built like tanks.

    This particular unit belonged to my father, who purchased it new in 1967 or 1968, and sprung for the optional 8-track player as well. I know, records, eight tracks, all obsolete. But that's the beauty of it. It can still play those old things, AND now it can play streaming audio and MP3s too. Museum piece? Maybe. But a WORKING museum piece. My daughter is fascinated by the record player. And another generation learns of Frank Sinatra...

    Xaenon, I congratulate you for a very nice reply to an arrogant Yuppie.

    ....and for a nice project, too.

    tinkering with older electronics has always favorite of mine. you never know what you might find when you open it up.

    I still work on and restore vacuum tube radios from the 1920's, 30's, 40's and 50's. It's a great hobby and there is some great Engineering in old hardware. Not everything relevant was designed in the last 5 years!
