Question on Phono Jack hookup

[vintage 5.0]

If one has a receiver and have one phono hook up. Can you use two y splitters and hook two turntables up to the receiver? I was just curious. Thanks

I have done that to AMPS. Two AMPS into one PREAMP and it worked. I don't see why it wouldn't for TT. :scratch2:

Hasn't this question come up before?

I don't remember the details, but the answer was 'no.' Something about the signal from the two cartridges interfering with each other.

 

[BinaryMike]

No. The cartridge wants to see a very specific load impedance, which would be completely upset by the presence of another cartridge in parallel.

 

[dumptruck]

Yeah, non-playing cartridge would affect the loading of the other cartridge, and be an antenna of some sort spliced into your tonearm leads.

Yup . . . the labels "input" and "output" are for humans. Electrons can't read. One cartridge will feed into the other. Bad idea. :nono:

Thanks guys that is why I like this site. A lot of great knowledge. So is there any other way or something you can buy if you have only one phono hook up on amp. I have three turntables and two amps with only one phono hook up each. I guess I can hook up two and let the other rest might be the easy and cheap way to do it.

You just need an audio input selector switch – something like this http://www.jaycar.com.au/productView.asp?ID=AC1655 . They are usually available at many electronics stores, either as audio, or audio/video selectors. Plug 3 turntables in, and the output into your amp's phono input, and select the required turntable with the switch.

:thmbsp: A switcher is perfect for your situation.

I use a JVC JX-300 A/V switcher for a similar application. It has a remote control so you can switch between sources from your listening position and it is dead quiet on the switching.

...or buy a standalone phono pre and connect it to a line level input on your amp.

That's what I was gonna recommend, though it might be cheaper to go with the selector switch.

Don't forget to ground those tables, too.

Cheaper, yes, but he might like the sound better than the internal phono pre and then he'll have to buy two more phono stages.
