Sansui 2000x Phone 1 and 2 inputs produce garbled sounds.

This sounds like a wiring problem. Perhaps a faulty earth connection inside the lead or the plugs to and from the turntable. Also check the connections to the cartridge, they can become loose or be connected wrong. Say a channel to the earth connection.

The Phono section has a very high level of amplification and so the audio input is very sensitive. So a possible faulty/loose grounding of the input can create a HUM which can be due to even a poor shielding of the input from stray AC factors. So you need to check for the these factors that can bring in the hum , you can confirm by isolating the phono circuit and working to the faulty stage.
Also it can be due to a faulty power supply - non filtering in DC- to the phono preamplifier.Finally faulty capacitors in power and feedback circuits can be a reason- check the negative feedback circuit which can be an op-amp with a feedback , check the capcitors here as a higher amplification can also be a reason.- check the preamp IC.

yes you can do that ,

Is it connected to a "PHONO" input or something not labeled explicitly for PHONO?

"PHONO" is the only designated connection on an audio device 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.

If your unit doesn't have a PHONO connection you will have to get a Phono Preamp to connect between the TT and any Line Level input, like Aux.

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.

Let's figure out which hardware is failing. Connect the phono preamp to the CD or tuner input to see if it works there. It should. If it does, your receiver is at fault. Did the front panel controls get damaged?

How did the turntable fare in this accident? As a basic test of its ability to produce sound, hook it directly to the CD input and raise the volume slowly while playing an LP. If it's alive you'll hear a very weak, tinny sound, but I assume you know that or you wouldn't have a phono preamp in the first place and would probably be asking why the TT sounds so poor. :-)

You did okay but the phono sockets are not for Computer/TV use. Phono sockets should be checked int the manual on why they're there. If you have connected the Bravia to your computer, using the appropriate cable, then you should also purchase or request from the retailer where you purchased the TV a cable that has stereo phono plugs and, you didn't say what size phono sockets they are but I presume they are 3.5 mm. So, if the TV has 3.5 mm sockets, you purchase a cable with stereo 3.5 mm plugs. This is adequate for the stereo wav sound coming from the computer and going into the TV. Remember, having 2 Phono inputs on the TV doesn't mean anything. The TV could have a number of video inputs too, ATD AVT, AV, COMPONENT1, COMPONENT2, HDMI1, HDMI2, HDMI3, etc. each have it's respective sound inputs for AV, S-VIDEO, DVD, Blue-Ray, etc. But for the computer there may be a different type of socket for it's sound inputs, normally it is the old phono sockets. Seek help from the retailer or else you could cook the circuitry of the TV's sound system.

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.

Hi,

Most if not all turntables would need to be connected to a PHONO INput which is high impedance with a high gain pre-amplifier stage. It will not work when connected to an AUX, CD or any line level inputs. Alternately, if your amp does not have any Phono Inputs, you can feed the turntable output to a preamp which can then be connected to any any line level inputs. An example may be found here or here. Additionally, there are some turntables with a built-in preamp.

Hope this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
