PRO SM-1
IMPORTANT INFORMATION...
Please read this entire manual before connecting the PRO SM-1 to your system.
For optimum performance:
• Always make sure that AC power is OFF while
making any connections.
• Do not use excessively long cables (i.e. over
50ft/14m). 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 controls. Residues will

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), consult a professional

technician.

• Never attempt to make any adjustments or repairs
other than those described in this manual. Take the
PRO SM-1 to your dealer or to an authorized
Service Center.
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 unsure which cables to use.
SYSTEM PRECAUTIONS
• Use appropriate cables throughout your system:
Quality shielded audio cables and terminated shielded
video cables, low-capacitance preferred. Speaker
cables must be at least 14-gauge; 12 or 10-gauge is
preferable.
• 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.
• Connect only one cable at a time, paying close
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 by moving
them slowly. Rapid adjustments may 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 any beverage
or anything wet on top of the mixer!
