Connecting Your Turnt able to a Receiver/Amplifier

You can connect your LAB-1100 to a receiver/amplifier (or stereo audio
mixer) that has low-level phono inputs (such as left and right PHONO
jacks) or line-level inputs (such as left and right AUX, TV, TAPE, or CD
jacks).

Cautions:

• Do not connect the turntable to AC power until you complete all other
connections.

• Do not place the turntable on top of the receiver/amplifier or on any
other component that gets hot.

• To avoid possible damage to your receiver/amplifier, turn it off before
making the connections

.

Note: If you are not sure which type of input your receiver/amplifier has,
check your receiver’s/amplifier’s owner’s manual.

Low Level Inputs

To connect the turntable to a low-level phono input, plug the white
and red plugs into the receiver’s/amplifier’s left and right PHONO
jacks. Then set LINE OUT ON/PHONO OUT OFF to

PHONO OUT OFF.

Line Level Inputs

To connect the turntable to a line-level input, plug the white and red
plugs into the receiver’s/amplifier’s left and
right AUX, TV, TAPE, or CD jacks. Then set

LINE OUT ON/PHONO OUT OFF to LINE
OUT ON.

Connecting to Power

Once you have connected the turntable to your
receiver/amplifier, plug the turntable’s power
cord into an AC outlet on your receiver/amplifier
or into a standard AC outlet.
Caution: To prevent electric shock, the plug’s blades are polarized and
fit only one way. If the plug does not fit easily, turn it over and try again.

Note: Depending on if your sound system has
PHONO jacks or not, be sure to set
LINE OUT ON/ PHONO OUT OFF as described in
“Connect Your Turntable”.

speed (33

1

/3 or 45 RPM).

the tone arm moves to the beginning of the
record, lowers to the record, then starts to play.

6. At the end of the record, the tone arm
automatically returns to the tone arm rest and
the turntable stops. To stop playing the record
sooner, press STOP. If the tone arm does not
automatically return when it reaches the end of
the record, press STOP to reset the
mechanism.

Care

Keep the turntable dry. If it gets wet, wipe it dry immediately.
Use and store the turntable only in normal temperature environments.
To protect the stylus from damage, we recommend you replace the
stylus cover when you are not using the turntable.
Handle the turntable gently and carefully. Don’t drop it. Keep the
turntable away from dust and dirt. Wipe the turntable with a damp
cloth occasionally to keep it looking new.

Cleaning/Replacing the Stylus

A dirty or worn stylus causes rough, distorted sound and could
damage your records.
Caution: Do not touch the stylus while cleaning or installing it. If the
stylus gets dirty or dusty, use a soft brush to gently clean it. If the
stylus is worn, follow these steps to replace it. You can order a
replacement stylus assembly AT3600LAX through your local

grasping its sides and pulling it down.
