PRO TT-1
IMPORTANT INFORMATION...
Please read this entire manual before
connecting the PRO TT-1 to your system.
For optimum performance:
• Always make sure that AC power is OFF while
making any connections.
• 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.
• 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)
• 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.
• 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.
• 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.
• The legs have functions for adjusting the height of
the unit itself. Adjust the legs to stabilize the main
body horizontally.
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 SYSTEM PRECAUTIONS
• 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.
• Be sure plugs and jacks are tightly mated. Loose
connections can cause hum, noise or intermittents that
could easily damage your speakers.
• 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.
• 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.
• Use restraint when operating controls. Try to move
them slowly. Rapid adjustments could damage
speakers due to amplifier clipping.
• 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.
• 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!
