MICROPHONE TYPE
The Microphone Input accept Low Impedance (250-600 ohm)
Microphones. The Microphone may be a balanced output type
(three wire) or an unbalanced output type (two wire).
PASO MICROPHONES
All PASO low impedance Microphones have a balanced output for
best performance. Connect the RED lead to terminal HOT, the
WHITE lead to terminal COM and the SHIELD to terminal G (see
Fig. 5A).
CAUTION
TO PREVENT POSSIBLE DAMAGE TO SPEAKERS OR THE
AMPLIFIER ALL INPUT CONNECTIONS MUST BE MADE WITH

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
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
in Fig 5B.
Be sure the cable length does not exceeds 15 Ft. (4.5 m).
