In the middle of laying out components with a client for his new system (using a Denon AVR-X3400H) it occurred to me tbat the turntable has a USB output. I don't bave even a moment to think about this, so I ask: is there a way to connect to the AVR using BlueTooth?

Thanks.

Sorry, must pay more attention to OP.

The AVR does have a USB input. Couldn't hurt to give it a try.

Might that usb output be used to connect to, oh, for example, a computer so that files could be made off of vinyl to store in an iTunes library?

Sell a new turntable.

The USB is to connect to a PC so software like Audacity can be used to copy the record in real time.
If it's a cheap POS turntable, then yes, it may well have bluetooth out, so you may be able to bluetooth it to your AVR. It will sound horrendous, but many customers will be over the moon just to play their old records.
Of course, plugging the RCA out into the AVR via the 3400's built in-phono stage is ideal...

Yes. We want to play the records with a bluetooth connection. That's what I'm after, not what you answered.


We're talking about a new turntable with a USB output. How would selling a new turntable help? I'd just be coming here asking if there was a way to use the USB output to create a bluetooth connection to an amplifier.

Wait a minute -- that's the subject of this thread!


We just set up the rest of his entire system in a new great $3000 cabinet from Pottery Barn that doesn't have a place to put the turntable.

He could have the turntable in another location of the room... and play through the amp via bluetooth.

By the way, it's a Technics turntable. I don't think they make any actual crap.

Ernie - more info in your first post would have helped everyone here... a model number would be cool.


The USB output will be useless.
You will need to go out the RCA into a phono stage - then transmit to the AVR using a Bluetooth sender.

Nothing about the situation is ideal, but it may work as long as the Bluetooth senders doesn't introduce any issues.

I'll get the model number when I can.

Okay, why is the USB outlet useless? Is it that there's no product that can take a USB digitization (whatever that is) of an audio signal and transmit it as bluetooth?

It's not that it needs to be put through a phono equalizer -- the audio would have to be equalized before being digitized for it to work with any recording program. I mean, an unequalized phono signal is about 20 dB down at 20 Hz and 20 dB up at 15 kHz (don't know the exact frequencies)! There's NO WAY you could just digitize that and send it to Audacity or a better recording program.

To be fair... I've never seen a Technics turntable with a USB port?
Are you sure it's not a copy of a Technics made by Audio-Technica?

The USB output will communicate with a computer but the stream is subject to the codec chosen by the manufacturer- if it's not compatible with the input (AAC vs WMP, as an example), you get bupkis.

You might want to look deeper into Audacity and some of the other programs- I thought at least one had RIAA equalization as an option although you could always use a phono preamp at the turntable (or, maybe the TT has a phono preamp with analog out).

Why use USB? It adds processing to the signal and it adds complexity to the system. If you had a signal that came from a phono preamp, you have many more options.

How much distance between the TT and the rest of the system? BT is not without its own problems. Is there a way to use a USB extension?

Have you seen this?

Ernie, try to keep up. Not all new turntables have a usb. Real turntables still have rca connections to go to the phone input on a receiver.

Sometimes I really do wonder how you make money.

Well, first of all, I've never seen a PHONE input on a receiver. After that...

What the hell, Fins? I never said new turntables all have USB connections, and I never said there's anything wrong with connecting a turntable in the old way.

I asked if a turntable THAT HAS a USB output can use Bluetooth to get the audio to an A/V system. THAT HAS IT ALREADY. ARE WE FOCUSED NOW?


Well, one way is that sometimes, at least, I pay attention to the subject on hand. Recently I made some money by listening to a client who wanted to talk about things other than what was needed at the moment. He went off on a tangent and we didn't get anything done, but I was on the clock. You guys have done this repeatedly here.

Hell, of course I know how to do it from the RCA jacks using a phono preamp and an RF system like those used to wirelessly get rear channel info to the rear channels. For what it's worth I know how to do this with a moving coil cartridge, a moving magnet cartridge, a ceramic cartridge, a crystal cartridge, a variable reluctance cartridge, steel needles and even cactus needles. But stick to the subject: I'm asking about a way using USB.

Do I have to insult people to get an answer? Okay: I'm guessing you guys are f*cking ignorant of what is needed but don't want to admit it.

Recently, on "Last Week Tonight," John Oliver discussed the ploy some people have of not addressing issues by asking "What about" and then naming some tangentially related subject.

Q: Can you use a USB output to somehow get audio via Bluetooth to a piece of A/V gear?

A: What about using the RCA jacks? What about a phono preamp? What about, what about....

What about if you can't answer the question, you don't answer some different question?

I now pledge myself to do the same, as I've been guilty of this, too.

I did answer the question. You just didn’t like what the answer is.

You told me how to use the USB output of a turntable that has one, to get the audio to a piece of audio equipment?

You didn't even tell me it wasn't possible, which is a possibility. THAT would have been an answer. You changed the subject. Changing the subject is not answering the question except in the magical mystical world of politics.

You got it! It's an Audio Technica AT-LP120BK-USB
