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

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.

• 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.

Service Center.

A NOTE ON CABLES:

• 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!

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.
