CONNECTION
AND
LOCATION
Place the mixer at the desired location. Ideally, the operator should man the console during
the performance
to
make adjustments
as
required.
If
this
is
not
possible, locate the console on the
stage
with
easy access
by
the musician/ operator.
It
is
strongly recommended that the console
not
be placed on top
of
or
in front
of
speaker cabinets (especially bass); this will cause vibration in
the mixer's reverb spring assembly.
Connect the speaker cabinets to the CORRECT
output
jacks. Always plug the speaker cable
into the mid-and high-frequency horn array cabinet first, and immediately plug the other end into
the high-frequency horn speaker
output
jack
on
the console. Then the bass cabinets may be
plugged into the console. As previously mentioned, permanent damage
to
the horn array will
result
if
plugged
into
the bass cabinet
output
jack. Always use cables made
of
lamp-cord type
wire#
18
AGW
or larger
for
speaker cables. A shielded microphone cable will melt and short
out
the power amplifier
as
well
as
cause a loss
of
high frequencies.
When connecting a Kustom monitorsystem
to
the console, a shielded microphone-type cord
must be used. The
monitor
output
is very
low
impedance and line lengths
of
up
to
200 feet may
be
used before excessive high frequency losses are noted.
OPERATI
ON
If
possiple, locate the speaker systems in
front
of
and directed away from the microphones,
greatly reducing the possibility
of
feedback. Feedback will occur
with
any type
of
PA system,
regardless
of
size or price, whenever the loudness
is
increased past a critical point determined by
microphone location, speaker placement, and room acoustics. Usually, little can be done to
correct
for
poor room acoustics. However,
with
·proper microphone selection and speaker
placement, the possibility
of
feedback can be reduced.
