Question about Audio Players & Recorders

1 Answer

My stereo receive hums annoyingly when I use my record turntable.

I have a old Technics SL-D2 turntable and JVC RX212 Receiver. If the receiver is on, the humming begins as soon as I select "PHONO." If the receiver is off and set to "PHONO", the humming begins about 3 or 4 seconds after I turn on the receiver. The commencement of the humming is sudden, not gradual.

    I turned over the non-polarized plugin for the turntable. The humming persisted. Not as loudly, but still annoying. I did learn, though, through this process that there remains a hum whether or not the turn-table is plugged in to an outlet. The stereo only has to set to the PHONO position. It is a bit louder with the turntable plugged in. I also noticed that when I unplugged the leadins from the turntable to the stereo (with the stereo on and in the phono position) I got a very loud hum momentarily as I did so.



    I'm baffled.

Just a suggestion, make sure the power outlet/s is grounded and that the polarity on both plugs are correct.

Technics SL-D33 Channel drop.


There's nothing wrong with the turntable then. It's your receiver that's the problem. In order to hear a magnetic cartridge it has to go via a pre-amp. It's this pre-amp that has failed in your receiver. It's only used by a turntable so wouldn't affect anything else. You should be able to trace this pre-amp by following the turntable socket wires. It will probably be a small IC that has failed. If you look up the number you should find it.

How i can add an old turn table


you'll will need a peamp device to boost the audio level of the record changer. preamps are still available try radio shack, they use to have one for about 40dls, but connect the turntable to an available input, something you are not using(aux) run a test with a record, you should be able to listen to the record but with a very low audio level, if you don;t then forget about the preamp and you'll need a a/d conversion device.

Technics SL1500 will not connect to new Sony STR-DH100 receiver


Unfortunately, a turntable runs on a different frequency, and if there is no button at the back of your receiver to change the frequency setting on that channel, it wont give you any sound. the best bet is to go to your music store and purchase a small DJ mixer. connect that to your receiver, and run the turntable through your mixer. the mixer will have the neccesary flip switches and "ground" connections

Technics turntable plays but no sound with Sherwood receiver


The problem is the fact that the new receiver has no phono input. The phono input has an extra stage of amplification built in. Your receiver is working fine. You need to purchase a phono pre-amp. These run around $20. Connect the turntable to the preamp and the presmp output to any line level input on your new receiver and everything will work as expected.

Connecting a Technics SL-BD20D turntable to a Yamaha RX-V463 Rece


After further research, I learned that I need to plug the turntable into a preamp before plugging it into my newer receiver. As with cassettes, record players are fading away. I ordered a preamp, but won't be able to experience success until it arrives.

How to connect turntable Technics SL BD20 to marantz SR7000 amp



Most recievers should have Phono Jacks labled on the back. That is where my Turntable an (MCS made by Technics but was sold under the J. C. Penneys name) connects on my JVC. I have 2 JVC 's One is old (1972) and one is new. Both of them have Phono jacks. Phono stands for Phonograph. This is an old term for turntables. The jacks should accept RCA patch cords. Good luck.
