sensitive to tonal balance,
the mid-range is important in adjusting the
qualitative
sonic
charac-teristics
of your system.
There
is controversy
among
engineers
and
audiophiles as to what the proper balance should be in this range. Moreover,
you will
find some 500 Hz, 1000Hz and 2000 Hz controls settings optimum for certain types
of music with other settings just right for different types.
The
Upper
Mid-Range
(approximately
2600-5200
Hz).
Speaker
designers
'often
boost output in this range to effect a quality of "presence" to the music. Too much
energy, on the other hand, sounds overbearingly harsh and strident.
A good balance
should be achieved
between
this
and a more
muffled
sound.
Use the 4000
Hz
control for this effect.
The High End (approximately 5200-20,000 Hz). The region up to only about 12,000
Hz or so is what
is normally perceived as high freequencies.
Adjustment
in this
range affects the brilliance of music, with too much
boost in energy
yielding on
unpleasant
and piercing quality.
Most adults have
hearing which
rolls off rapidly above
14,000 to 17,000
Hz. As a
consequence,
the 16,000
Hz control will have a very subtle effect. It can be used to
add a little more dimension to the sound or as a very high frequency noise filter.
SAFETY; USE AND CARE INSTRUCTIONS
Read Instructions - All the safety and operating instructions should be read before
your Equalizer is operated.
Water and Moisture- Your Equalizer should not be used near water - For example,
near a bathtub, washbowl,
kitchen sink, laundry tub, in a wet

from heat sources
such as radia-
tors, heat registers, stoves, or other appliances (including amplifiers) that produce
heat.
Power
