Very Important
Please read this section before connecting this unit to your system:
For optimum performance:
•
All the slide faders are subject to wear. Excessive force can wear out the fader
quickly.
User
replaceable slide faders are not a warranted item.
•
Never use spray cleaners on the slide controls. 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) consult a professional
technician.
•
Always make sure that AC power is
off
while making any connections.
•
Use appropriate cables throughout your system. Do not use excessively long cables (i.e. over 32 feet
/
1 O meters) Be sure plugs and jacks are tightly mated.
Loose
connections can cause hum, noise or
intermittents that could easily damage your
speakers.
Make the input and output connections with
readily available
low-capacitance
stereo cables. Quality cable makes a big difference in audio fidelity
and punch. See your Denon Professional dealer or an electronics or audio specialist store if you are
not sure which cables to use.
•
Never attempt to make any adjustments other than those described in this
manual,
or
repairs.
Take
the unit to your dealer or to an authorized Denon Professional 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.
•
Use restraint when operating controls. Try to move them slowly. Rapid adjustments could damage
equipment 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 its 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 near or on top of the unit!
•
Headphone outputs can be set to levels which can cause damage to your
ears.
Use
caution.
•
This unit may contain a microcomputer for signal processing and control functions. In very rare
situations,
severe interference, noise from an external
source,
or static electricity may cause it to
lockup.
In
the unlikely event that this should
happen,
turn off the unit, wait at least five
seconds,
and
then turn it back on again.
•
Under rare
circumstances,
if this product is exposed to electromagnetic interference during
use,
there
may be a slight drop in signal-to-noise
ratio.
•
Intended electromagnetic environments:
residential,
commercial, light
industrial,
urban
outdoors.
