THE AMPLIFIER
BALANCED MICROPHONE
IMPORTANT NOTE: The use of an
unbalanced Microphone (two leads) is
not recommended. For best results in a
PA Application always use a
Unidirectional Dynamic, Low
Impedance, Balanced Microphone
(three leads).
UNBALANCED MICROPHONE
Attach the Microphone leads to the ter-
minal strip as per diagram in Fig 10A.
The cable length should not exceed: 15
Ft. (4.5 m).
Fig. 10 - Balanced Microphone Input 1 Wiring
CAUTION: TO PREVENT POSSIBLE DAMAGE TO SPEAKERS OR THE AMPLIFIER
ALL INPUT CONNECTIONS MUST BE MADE WITH THE AMPLIFIER POWER OFF.
CABLE LENGTH - If the distance
between the Microphone and the
Amplifier Input is greater than 15 ft (4.5
m) a Balanced Microphone must be
used. Use a two conductor shielded wire
and connect Microphone to Amplifier as
per Diagram in Fig. 10.
MICROPHONE CABLE ROUTING - The
Microphone Cable should be carefully
routed. Improper Cable routing will
cause spurious oscillations, regenerative
noises, hum, etc. that may permanently
damage the Amplifier.
z
Do not route cable next to power
lines.
z Do not route cable near or over
Fluorescent Fixtures.
z Do not route cable next to
Speaker Wires.
z Do not install cable inside Power
Line Conduits.
z Avoid the use of staples that may
penetrate the cable.
