PHONO PREamp. Does that suggest anything?

No picture necessary. YOU can see it. I can visualize.

Turntable to the Pre-amp IN. Preamp OUT to ANY available RCA input (usually AUX,).

    INs to OUTs means between different devices, not on the same device. Every output feeds an input somewhere else.

    Turntable OUT (the only direction it has) to the Pre-amp IN. Preamp OUT to ANY available RCA input ON THE RECEIVER (usually AUX).

    Nothing will blow up from the RCA cables. They're all low voltage, referred to as Line Level. The preamp takes Tuirntable cartridge level (very very small) and PREAMPLIFIES it to Line level for use by standard audio circuitry. It also messes with the frequency balance because the sound was severely changed to make it fit the grooves on the record. Google RIAA equalization. THAT is why PHONO only connects to PHONO. It is unique.

    Red and White are Right and Left, respectively of your turntable's cartridge is wired correctly. It's just color coding for YOU to use in wiring and to help you keep continuity throughout multiple devices. It's all academic anyway. Maybe you would prefer to have the guitars on the opposite side. If you want to hear both channels you will have to connect both cables from the source through every device.

Cannot hook up sound to surround sound , everything else works, cd player, radio, tapedeck. just the turntable does not work. any suggestions? deb


Hi, you need to connect the turntable to your amp via a phono input connection. If no phono input available then a pre amp needs to be used between turntable and amp to up the signal. Cheers John. Styluscity@gmail.com

I have a Technics Quartz SL-10 Direct Drive Automatic turntable and I need a pre-amp to drive it through a JVC RX-6012VSL Audio Control System.....preferably a Technics pre-amp.

There are, of course, many non-Technics PHONO preamps out there.

If you already have the central receiver and amplification part nailed down you really only need a Phono Preamp to boost and shape the output of the Phono Cartridge. Otherwise you're paying for source switching, volume and tones controls you don't need.

Connected to turn table. having sound problem. At 99, sound hardly audible.


The bose as most all in one systems do not have an inbuilt phono stage. Phono especially MM type have a very low signal and an eq curve that gets altered in the phono stage. Without a phono stage (known as a phon pre amp) you will not get much fun from your turntable. To connect : turntable out - into phono preamp - phono pre amp out into bose line in/aux in

I have a new Yamaha RX-V365 receiver and an older technics turntable, regardless of input setup I cannot get any volume from the turntable, yet all other inputs like CD, Tuner are fine....amp issues in...


Some turn tables do not have a built in amp, especially the older ones, the sound goes from the needle to the output. If the amp your are using does not have a designated phono, turn table, input it may not have the turn table pre-amp built in. Some turn tables have to be grounded to the amp to work properly.

Ipod input for sa-eh760


You can plug the Ipod into the mic input , to do test recording. But the result wont be great.

To listen the Ipod in your stereo you should plug the Ipod into the Auxiliary input on the stereo.

Naturally you do not need any dvd.

Here is the adapter: 1.5M 3.5mm Male to Male AV Audio RCA Y Adapter

The aux wont work on a TT . You need a turntable pre-amp. Then you can plug it into the aux jacks.

Please let me know how your turntable is connected to the music system. I mean, to which input ? (Tape/Aux/Phono/VCR/CD) ?
