Sony HCD N555AVK Service Manual

A turn table produces sound voltage in the millivolt range. If you have it connected to a receiver that has a phono input and the turn table is pre-amplified, you are overdriving the receiver and it is clipping the audio and making it sound bad.

It can be done but it is not easy. Looking at the schematics you can input the turntable into the microphone inputs. Depending on what you can do with the tone controls you may get it to sound ok. If it is to loud you can add an attenuator in series with the turntable and you need to also add RIAA equalization (just an RC network).

It will be interesting to see this on a motorcycle!

You have to go in through the microphone inputs, that may not work to well but it is a starting point.

many decks have pre amps or need preamps. hence the reason why you have distorted sound i would guess. you need the opposite of what you used. What record deck did you try?

"PHONO" is the only designated connection on a receiver that is literal and exclusive. Nothing but PHONO will work right on it and old-school turntables would require it to preamplify the tiny current produced by a Phono cartridge.

BUT, modern turntables like your come with their own preamplifiers, so they MUST be connected to a garden variety Line Level input like AUX (anything BUT Phono or it will overload).

"LP DOCK also has a line-level output for connecting to any home stereo with an AUX input"

As far as WHY your amplifier isn't making da music, that could be whole 'nother problem.

We'd need more details about it and the speakers to go there.

It might, however if the LP is damaged or got something stuck in the groove no. If it only does it on one LP and no others then, again the answer is no. However if any other record shows signs of poor sound then the stylus might indeed need changing.
If you need a good record cleaner (that gets rid of static too) try the website below. I use the cleaner all the time it's good stuff.

I have a Sony SDLX250H connected to my computer right now, using an adapter for RCA to 3.5mm, into the line in jack. You could do the same thing, and probably use Audacity to do some recording. Wish you the best!

Possibly check the wires on the cartridge, make sure none of them are touching and are not bent to badly, are all the connections tight? some cartridges require plastic sleeves over the connections, this insure they don't touch and
avoids resistances between them. Also some cartridges are not compatible with certain model turn tables.Is it universal? Also you my need a mixer most turntables don't work with amps alone. Mine don't. Usually most models you attach the ground wire to the mixer. A mixer boosts table power and take stress off the amp. Hope this helped! good luck!
