Re: turntable setup into an hp 7590
In theory as long as you have a sound card installed, yes you can connect your turntable direct to your computer simply by connecting it to the audio input.
You will probably need a patch lead with twin line phono connectors on one end and a stereo 3.5mm jack plug on the other end.
Please note, the turntable or phono inputs on amplifiers are unlike all the other inputs, because they have a particular frequency response tailored for use with a headshell cartridge.
If you connect your turntable to an input that has not been tailored to the RIAA response curve, it will sound tinny. This is what probably happens when you connect to your computer. The input may also not be sensitive enough.
You may be able to adjust the frequency response if your sound card includes an equaliser. Alternatively, you may be able to download some audio software that will allow you to equalise your turntable.
All in all though, I'm sorry to say you would be better off with an outboard preamp.

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.
The red wire is the right channel, so going back to your amp, get a single phono plug with with the wire exposed, so you can touch the wire. Then remove the turntable connections. With the amp on plug the the lose wire plug into each channel and check if the sound on the right is still low. If it is then there's a problem with the magnetic cartridge pre-amp inside the amp. They are often located near the phono socket on a seperate PC board, but if not just follow the red wire to the main board. Chances are it will be an IC that's failed.
If it has a strong buzz at the back of the amp. Then I should replace the wire between the turntable and the amp. Or the right phono plug that connects to the amp.
plug a red and white rca cable into the back of the turntable and then plug the other end into your phono output at the back of the amplifier.then turn your selector on your amplifier to phono.wowla you should have sound
If your turntable has an amplified output, go ahead and plug it in to the aux port. If not, you won't be able to use it with your receiver properly. Look on the back (or front) of your turntable for a knob labeled "level" or "volume", and that will determine if it's amplified or not. Good luck, I hope this helps!
there is a switch that cuts off the signal when the tone arm docks.check the wiring is not broken inside and that the switch is ok.typically,red green white black red and white are plus and left ground is green and right ground is black.the collar that screws on to the head unit has 4 pins.make sure the contacts are clean.measure the wires one at a time from the tone arm to the rca plugs on the back.the green and black go to the outside collars,and the red and white go to the center pin of the rca plugs
