IMPORTANT INFORMATION...
Please read this entire manual before
connecting the PRO TT-1 to your system.
For optimum performance:
GENERAL SYSTEM PRECAUTIONS
• Always make sure that AC power is OFF while
making any connections.
• Use appropriate cables throughout your system:
Quality shielded audio cables and terminated shielded
video cables, low-capacitance preferred. Speaker
cables must be 14-gauge minimum; 12- or 10-gauge is
better.
• Do not force the platter to stop moving
while the motor is engaged. Quality
slipmats should be used to hold records in
position. Forcing the motor to stop can
damage the motor assembly.
• Be sure plugs and jacks are tightly mated. Loose
connections can cause hum, noise or intermittents that
could easily damage your speakers.
• Never use spray cleaners or oils on the slide
control. Residues cause excessive dirt build-up
and this will void your warranty. In normal use
slide controls can last for many years. If they
malfunction (usually because of a dirty or dusty
environment)
• Reliability will be enhanced through the use of
banana connectors on the speaker wires. Observe
correct speaker wire polarity. If in doubt, consult your
dealer or a qualified technician.
• Take care to connect only one cable at a time. Pay
attention to the color-coded, labelled Input and Output
jacks.
• Never attempt to make any adjustments or repairs
other than those described in this manual. Take the
PRO TT-1 to your dealer or to an authorized
Service Center.
• ALWAYS remember: “TURN AMPS ON LAST
AND OFF FIRST”. Begin with master faders or
volume controls on minimum and the amplifier
gain/input control(s) down. Wait 8 to 10 seconds
before turning up the volume. This prevents
transients which may cause severe speaker damage.
• Do not place the unit in a location where it will be
exposed to direct sun light or near a heating
appliance.
• Do not place the unit in a location where there is high
humidity or a lot of dust.
• Use restraint when operating controls. Try to move
them slowly. Rapid adjustments could damage
speakers due to amplifier clipping.
• Cartridge may pick up slight sound pressure or
vibrations of the speakers coming along the floor or
through the air resulting in howling. Find a location
which is very stable and free of vibration.
• Avoid amplifier “clipping” at all costs: this
occurs when the red LEDs (usually on the front panel
of most professional power amplifiers) start flashing.
“Clipping” is when the power amplifier is distorting
and working beyond it’s limits. Amplifier distortion is
THE major cause of speaker failure.
• The legs have functions for adjusting the height of
the unit itself. Adjust the legs to stabilize the main
body horizontally.
• To prevent fire or shock hazard, do not expose the
unit to rain or moisture. Never place cans of beer,
soda, glasses of water or anything wet on top of
the turntable!
A NOTE ON CABLES:
Quality cable makes a big difference in
audio fidelity and punch. See your
dealer or an electronics or
audio specialist store if you are not
sure which cables to get.

GENERAL OPERATING INSTRUCTIONS...
1. Turn the power dial to turn on, the speed indicator and the strobe-illuminator will light up.
2. Turn on and raise the target light for illuminating the stylus tip by pushing the target light button.
3. Place a record on the turntable mat, when playing a 45rpm record with a large center hole, place the
45-rpm adaptor on the center spindle.
4. Set the rotation speed (33/45/78) to match the record.
5. Release the arm clamp.
6. Set the cueing lever to the up position.
7. Press the Start/Stop button, the turntable platter will start to rotate.
8. Move the tonearm over the desired groove.
9. Set the cueing lever to the down position, the tonearm will descend slowly onto the record and play
begins.
10. Adjust the pitch to a desirable speed. The pitch control is variable in a range of +/- 10%. During
play, observe the strobe dots, if the strobe dots appear to the right, the pitch is slower than the rated
speed, if flow to the left, the pitch is faster than the rated speed, if the strobe dots appear stationary,
which means the platter is in normal turntable speed. Move the pitch control slider up or down to
adjust the speed.
11. To suspend play, lift tone arm with cueing lever.
12. When play is finished,raise the cueing lever, move the tonearm to the arm rest, secure the tonearm
with the arm clamp.
13. Turn off the target light off by pushing the light back down.
14. Press the Start/Stop button to stop the platter rotating, turn the power dial to turn off the power.
Maintenance..
Routine maintenance should be performed by cleaning the stylus periodically with a soft brush to
prevent the accumulation of dust. When the sound becomes distorted or noisy, check the stylus. If
it is worn out, replace with a new one. From time to time, the dust cover and turntable cabinet should
be wiped with a soft, dry cloth. Use of any volatile materials as alcohol,thinner, benzine, etc.,may
remove the paint or damage the luster and should not be used.
