SOURCE: belt is off my audio-technica turntable at-pl50

WASH YOUR HANDS FIRST! Any oils on the drive belt may cause slippage.

This is from the manual:

A) Remove the record mat from the turntable platter
(Fig. 10a). Through an opening in the
turntable platter, visually inspect to see if the drive belt
is around the motor pulley (Fig. 10b).
B) If the drive belt is not around the motor pulley: Lift
and remove the turntable. Place a thumb into each of
the left and right openings on the turntable platter; and,
using the fingers to press down on the turntable housing’s
surface, pull the platter straight up (Fig. 10c).
Avoid pressing on the tone arm.
C) With the turntable platter bottom side up, place the
belt along the outside wall of the turntable platter's
drive rim, making certain that the belt is smooth and
flat all the way around (Fig. 10d).
D) Put the turntable back on the center spindle, make
certain it is fully seated, and align one of its openings
over the motor pulley position.
E) Through the opening, carefully hook the turntable
belt with a finger or with the original red ribbon (never
use a sharp object) and pull the belt over the motor
pulley (Fig. 10e). Make certain the belt is not twisted
between the pulley and the platter’s drive rim.
F) Put the record mat back on the platter.
G) While holding the tone arm in its rest position,
slowly turn the platter by hand clockwise at least 10
rotations to clear the mechanism’s automatic cycle.

SOURCE: My audio-technica PL50 plays 45s at the wrong speed.

believe it or not not it probably doesn`t even play your lp`s at the right speed? Its probably because your drive belt has actually stretched? rubber belts do wear and maybe seek out a replacement drive belt?

try this company?

How to hook up sony str dg600 with a turnable?


Possibly. It depends upon the type of cartridge used by your AT turntable. If the volume is very low, there may not be enough output.

I have an Audio-Technica turntable (AT-PL50). I recently moved and when I hooked my turntable back up, the sound is terrible. It sounds distorted, similar to the sound of blown-out speakers. But, I checked...


it sounds like your cartridge is shot and damaged.
this turntable has fixed cartridge and only the stylus can be changed.

check out this manual: http://www.audio-technica.com/cms/resource_library/literature/0fb01429606842cf/at_pl50_om.pdf

Belt came off when I moved it, just need to know how to put it back on. I know that it should be on the golden spinning part, how else is it placed?


Hi put the belt on the platter first, remove the rubber cover and then place the platter back on. There should be a hole through the platter where you can grab it, then stretch it to go over the motor spindle. Hope that helps

Distorted sounds


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.

Sound very distorted


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.

No sound from my record turntable into my computer.


If you're certain there is no sound going out of the TT...

Setting the Pre-amp Switch
For increased flexibility of use, this turntable has an internal
stereo phono pre-amplifier. The Pre-amp Selector Switch
is located under the turntable platter, in the rear-center
(Fig. 1). If the system amplifier you are using has a PHONO
input, set the Pre-amp Selector Switch to the “OFF”
position. If your amplifier does not have a PHONO input,
set the Pre-amp Selector Switch to the “ON” position and
connect the turntable’s output cables to the AUX or other
high-level input on the amplifier (described later).

Turntable operates, but no sound at all
1. The stylus guard is still in place.
2. The tone arm Lift button is pressed in.
3. Amplifier controls set incorrectly: wrong input selected,
tape monitor on, speakers switched off, etc.
4. Check the stylus on phono cartridge for correct placement.
Refer to the instructions for replacing the stylus
on page 5.
Turntable operates, but no sound, or sound not loud
enough
1. If the turntable is connected to an AUX (high-level)
input: The Pre-amp Selector Switch may be set to the
“OFF” position (phono-input level).
2. The input gain of the amplified speaker or similar
device may be too low.
3. The stylus assembly may not be fully seated in the
cartridge body.

You could also isolate the problem to either the TT or the PC by trying the TT on some other sound device like a receiver. Make sure the PreAmp Selector switch is ON and plug the TT into any AUX, CD or TAPE input.

Built in Pre-Amp has gone out


Remove the turntable pad (part where the record sits) and the switch is in the corner.

Background huming


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.
