IMPEDANCE SELECTION
The Model 565 is dual impedance for connection
to microphone inputs rated at 19 to 300 ohms or to
high-impedance microphone inputs.
Either high- or low-impedance operation is selected
by the leads chosen for connection at the equipment
end of the microphone cable. For high impedance, the
RED lead is the "hot" conductor; the shield is con-
nected to the amplifier or chassis ground. For low
impedance, the BLACK and WHITE leads are the "hot"
conductors; the shield is connected to the amplifier
or chassis ground.
The low-impedance connection is recommended
where long cable lengths are required or under condi-
tions of severe hum disturbance. The permissible cable
length is practically unlimited, since neither response
nor level is appreciably affected. For use with high-
impedance amplifiers, the Shure Model A95 Series
Line Matching Transformers are available for coupling
a low-impedance line to the amplifier input. The Model
A95 Series transformers permit coupling a 19 to 300
ohm microphone line to a high-impedance input.
PHASING
To test two microphones for proper phasing, connect
them to an amplifier and talk or sing into them while
holding them three or four inches apart. The sound
from the speakers should be the same when talking
into either microphone or directly between them if they
are in phase with each other. If the sound drops dras-
tically, or if a dead spot is found when talking between
the two microphones, the microphones are out of
phase. All microphones should be tested in this manner
to insure that they are in phase with each other.
To change the phase of a low-impedance micro-
phone cable, interchange the BLACK and WHITE cable
leads where they are connected to the sound system.
To change the phase in the microphone, the micro-
phone cartridge leads must be interchanged (see Fig-
ure 3). This should be performed by your dealer, the
Shure Factory Service Department, or other qualified
service personnel.
ARCHITECTS' SPECIFICATIONS
The microphone shall be the Shure Model 565 or
equivalent. The microphone shall be a moving coil
(dynamic) type with a frequency response of 50 to
15,000 Hz. The unit shall have a "cardioid" polar
characteristic. The cancellation at the sides shall be
approximately 6 dB, and the cancellation at the rear
shall be 15 to 20 dB. The microphone shall be dual
impedance with a rated impedance of 150 ohms for
connection to microphone inputs rated at 25 to 200
ohms and High for connection to high-impedance mi-
crophone inputs.
The microphone output shall be:

The microphone shall be provided with a swivel
adapter, adjustable through 90" from vertical to hori-
zontal and suitable for mounting on a stand having a
78"-27
thread. The microphone shall also be provided
with a detachable 4.6m (15 ft) three-conductor shielded
cable with an Amphenol MC4M or equivalent connect-
or at the microphone end. The overall dimensions of
the microphone shall be 153 mm (6-1/32 in.) in length
and 51 mm (2 in.) in diameter.
