Just connected new turntable AT-PL50. Connected the red pin-plug to the right channel input and the white pin-plug to the left channel input of the amplifier. Sound very distorted. Even getting some distortion noise when no record is playing.
This turntable has a preamp switch on it, which is probably on and what is causing the distortion. Take off the metal record platter by lifting up on the two holes gently. Turn the pre-amp switch to 'off' and then try it again. This is probably it...
Or you can plug it into an input that doesn't have a preamp and that should work.

The RCA plugs are the Right (red) and Left (white) sound channels. The 3 thin wires are the power connect. It's likely this will only fit one way into the unit, unless you have broken or cut of the connector. One wire will then be the + wire (under 12volts DC) the other - wire and the other earth. As long as the wires don't touch each other all that will have is the turntable will go backwards if the - wire is connected to the plus terminal. The phono plugs reversed will simply switch the left sound coming out of the right channel etc...
Hi, Here's a solution to see if you have a problem with either your receiver or turntable. The turntable has 2 RCA's one red for right channel, and one white or black for left channel, which plug into the back of the amplifier.
Unplug both RCA from rear of amplifier.
Plug in a cd or dvd player into those inputs on the amplifier, the sound will be lower but it will give you an indication if the amplifier is ok or not.
If you have sound on both channels left and right then the amplifier is good
If you still only have sound on left channel, then there is a problem with the right channel input on the amp.
If your amp, is good, unplug the cd /dvd player.
Put a record on and start playing the record
Plug the white or black RCA from the turntable into the rear of the amplifier marked left, you should have sound.
now unplug it from the left and plug in into the right red RCA socket, if you have sound the amplifier is working fine.
if there is no sound there may be a problem with the stylus cartridge on the turntable
now lets reverse the test
unplug both RCA from amp.
Plug the red RCA into the left socket on amplifier, if there is sound, turntable is working fine, if no sound there is a problem with either the stylus cartridge or that red RCA cable.
now unplug the red RCA from the left side and plug it into the right side socket
if there is no sound there may be a problem with the stylus cartridge or RCA cable.
Take the adapter cable from the Wii that plugs into the back of the Wii and converts the output(audio/video) into RCA style pin plugs, you will have: RED=right channel audio, plug it into any of the red audio INPUT on your Onkyo, then you will have WHITE=left channel audio, plug it into the other white INPUT jack next to the red plug on the Onkyo, then you will have YELLOW= video(picture) that will go directly to the yellow video INPUT on the back or side INPUTS of your TV.
Then when you want to play the Wii, set the input mode on the Onkyo to the inputs that you connected the red and white plugs into, then change the input on your TV to which ever the input is labeled on your TV in which you plugged the yellow plug into, you now will have sound comming from your Onkyo and the Wii up on the TV screen ready to play. Good luck!
If you put the good channel from the deck into the right and then left phono imputs of your amp, the sound should come out from the left and right speakers. If it only comes out from the left, then the amp as a right hand channel fault. Now if other devices work on both channels, then it's the pre-amp for the phono socket that has a fault on it. You should be able to find this by following the wires from the phono socket. If you touch around that pre-amp you should get it to buzz on either channel (where it joins with the main pre-amp). Doing this with a screwdriver will pin-point where the faulty part is (working backwards). PS don't short anything by touching to bits of metal together with the screwdriver.
Magnetic cartridges need a small pre-amp before they can be past to the main pre-amp. That's why you can't hear anything with the deck plugged into another line socket.
If you get signal on both left and right speakers with the above test the deck is to blame.
Have you tried swopping over the output leads from the turntable to the amp (normally one red and one white phono plug) so they are in each others socket? If you do this and you still get no sound from the right channel it is almost certain to be a faulty amp,or speaker. If you swop and get no sound from the LEFT channel it is could be either a faulty lead or cartridge.
