For incr 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 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).

Connecting to Computers or Audio Devices with 3.5 mm Input
T-PL50 connects without adapters to devices equipped
The A with RCA connectors. For maximum flexibility, we have included two adapter cables to fit other popular audio inputs.
The first of these adapter cables–dual RCA to stereo 3.5 mm mini-plug (male)–is designed to fit most popular computer* audio inputs. It may also be used to connect the turntable's RCA output to other equipment, including:
• a stereo/boombox* equipped with a 3.5 mm mini input
• powered speakers* equipped with a 3.5 mm mini input
• a mixer* or PA system* equipped with a 3.5 mm mini jack
The second included adapter cable–dual RCA to stereo 3.5 mm mini-plug (female)–permits connection of the turntable output to amplified speakers* or similar devices. The 3.5 mm ster
eo mini-
jack on the cable adapter accepts stereo mini-plugs.
On both cables, the “tip” carries the signal for the left channel, the “ring” carries the right signal, and the “sleeve” is ground/common.
To use either adapter cable, connect the turntable's red and white RCA-type plugs to the cable adapter's RCA-type jacks.
* When using either cable adapter, always set the AT-PL50 turntable’s Pre-amp Selector Switch to the “ON” position. (Switch is located under the AT-PL50 turntable platter.)
Automatic Operation
1. Remove the stylus guard from the stylus assembly (Fig. 3).
2. Put a record on the turntable. If needed, use the 45 rpm adapter (Fig. 4).

NOTE: If connection is desired to a mono amplifier/speaker, make certain to use a stereo-to-mono adapter, available from your dealer or an electronic parts store. Inserting a mono plug in the stereo jack will disable one of the stereo channels. Other adapter cable configurations will be available from dealers and parts stores for connecting to devices needing different terminations.

While holding the head of the tone arm, rotate the front of the stylus assembly in a forward and down motion to remove it (Fig. 8). (As you remove the old assembly, note its position and “feel,” to aid in properly installing the new one.)
Install the new stylus assembly as shown in Figures 9a/9b, being careful not to touch the actual stylus. Make certain that the projection at the back of the assembly is fully seated in the cartridge body
first (Fig. 9a), and that the assembly “clicks” up into place, with no gap between its top edge and the front of the black plastic tone arm head (Fig. 9b). Replace the stylus after 400 hours of use.
To maintain original performance, insist upon a genuine Audio-Technica brand replacement stylus. Look for the Audio-Technica trademark ( ) on the front of the stylus assembly and on the packaging.

C) With the turntable platter bottom side up, place the belt along the outside wall of the turntable platter's drive rim, making cer 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 ( 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.

Troubleshooting, continued
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

If the pre-amp switch is set to the “ON” position (AUX high-level output), a phono input will be overloaded.
If this causes the turntable to be unable to trace the record, please contact your dealer or our service department.
Make very certain the surface upon which the turntable is resting is not picking up vibrations from the floor or walls, or from direct speaker sound.
