On a sony lx350h turntable belt drive i hardly have any sound. Connected through a sound system. Will i need a phono pre-amp?

Yes, a TurnTable can be connected to any of the Analog Audio Input ports on the Sony STRDH130 Receiver. However, the turntable signal will need amplification from an external pre-amplifier (or an inline amplifier) as this Receiver does not have a PHONO input.

Remove the drive belt and see if the turntable spins, if it does the drive motor is faulty, if it doesn't then (if this is a new turntable) it's possibly got a locking device to hold the turn table steady during shipping.

No...

Try attaching a ground cable between any metal point on the turntable chassis and a screw on the chassis of your amplifier.

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

Did you inherit this machine this way or did this problem just appear out of nowhere?

Page 8 shows how the cartridge attaches to the headshell.

The AT-PL120 uses a magnetic cartridge to extract a music signal from the record. Magnetic cartridges all put out a very weak electric signal, and so their output must be strengthened, or amplified, to where it is as strong as the input from, say, a CD player. This amplification is provided by a pre-amp. If your receiver has dedicated "phono" inputs the pre-amp circuits are already in the receiver. If you do not have dedicated phono inputs you must either buy a pre-amp, or buy a magnetic cartridge turntable with a pre-amp built into itself. The AT-PL120 has a built in pre-amp. You can switch the AT-PL120's preamp on or off. The switch is located under the platter at the back side of the turntable. Take the platter mat off and turn one of the platter's holes to the back and you should see the switch through the hole. If you push the switch to LINE OUT the preamp is turned on and the turntable sends an amplified cartridge signal out the cables which MUST be connected to a receiver inout suitable for a CD player (a "high level" input). If you push the pre-amp selector switch to PHONO OUT the turntable sends the weak unstrengthened cartridge signal out the cables which MUST be connected to the receiver's dedicated PHONO inputs so the signal can be amplified with the receiver's own pre-amp circuits.

If everything is set wrong (i.e. LINE OUT (pre-amp on), and connected to phono inputs) you are applying two steps of strengthening to the turntable's signal which is too much. The resultant sound will be garbled. Try not to do this!

The other way to do everything wrong is set the pre-amp switch to PHONO OUT (pre-amp off) and connect the turntable's cables to a high level input. If this happens the turntable signal receives no amplification and the resultant sound will be thin and weak.

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

You have to make sure your unit is connected to the PHONO INPUT connection on your receiver. If your receiver does not have a PHONO INPUT connection, then you will need to buy what's called a PHONO PRE-AMP - AVAILABLE HERE.

You connect the turntable to the Phono Pre-Amp, then you connect the Pre-Amp to the LINE IN or AUX IN of your receiver.

How does it sound when you just play straight vinyl through your system? If you still get that hum, issue might also be faulty RCA cables, and even cartridge. So you would need to test everything out.

You don't really need a pre-amp unless you are connecting straight into your pc from your turntable. In that case, yes you will need a pre-amp, and this actually might be the cause of everything. If you are going into a DJ Mixer or a receiver, and your turntable is connected to the PHONO INPUT connection, you do not need a phono pre-amp.

Here are some inexpensive PHONO PRE-AMPS.

Hope this helps some.
