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, Low Impedance, Balanced
Microphone (three leads).
CABLE LENGTH - If the distance between the Microphone and
HOT
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. 5A.
MICROPHONE CABLE ROUTING - The Microphone Cable
should be carefully routed. Improper Cable routing will cause spu-
rious oscillations, regenerative noises, hum, etc. that may perma-
nently damage the Amplifier.
Do not route cable next to power lines.
Do not route cable near or over Fluorescent Fixtures.
Do not route cable next to Speaker Wires.
Do not install cable inside Power Line Conduits.
Avoid the use of staples that may penetrate the cable.
UNBALANCED MICROPHONE
Attach the Microphone leads to the terminal strip as per diagram
HOT
in Fig 5B.
Be sure the cable length does not exceeds 15 Ft. (4.5 m).
