545SD -- Vocal Microphone
General Description
The Model 545SD is a dual-impedance, unidirec-
tional, dynamic microphone. Shipped connected
for low-impedance operation, it features a silent
magnetic reed on/off switch.
The Classic Unidyne is a favorite for instrument
pickup and recording,and can be used on
lecterns for public address systems such as
those used in political conventions and legisla-
tures, convention halls, hotels, public auditori-
ums, stadiums, schools, and churches.
Features
•Exceptionally uniform cardioid pattern minimizes feedback in PA applications
•Selectable dual-impedance operation
•Silent magnetic reed on/off switch with lock option
•Cardioid dynamic
•Frequency response: 50 to 15,000 Hz
Connections
When using the microphone with a balanced input, pins 2 and 3 are the audio signal carriers. When using the mi
crophone with an unbalanced input, use a cable wired with pin 2 as the signal carrier and pin 3 connected to the
cable shield (ground), such as the Shure C20AHZ high-impedance cable.

Impedance Selection
The microphone is shipped connected for low impedance operation. To change to high impedance, proceed as fol
lows:
1. Remove plug element at receptacle end of microphone by turning slotted setscrew in (counterclockwise) and
carefully withdrawing plug element from case.
2. Disconnect 2-terminal impedance selection socket from rear of plug element.
3. Reconnect 2-terminal impedance selection socket in reverse position so that pin 3 of plug element is inserted
in socket terminal "H" (White).
4. Reassemble plug element into microphone and seal setscrew securely by turning out (clockwise).

Polarity
All cables and microphones should be tested to ensure that they have the same polarity. To test two microphones
and/or their cables for proper polarity, 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 the sound drops drastically, or if a dead spot is found when talking between the two mi
crophones, either the microphones or their cables have opposite polarity.
To change the polarity of a microphone cable, either use a Shure A15PRS phase reverser or interchange the wires
connected to pins 2 and 3 of the threepin connector at one end of the cable. To change the polarity of a micro
phone, the microphone cartridge leads must be interchanged. This should be performed by your dealer, the Shure
Factory Service Department, or other qualified service personnel.

Impedance
Dual. Microphone rating impedance is 150 ohms (250 ohms actual) for connection to microphone inputs rated at
19 to 300 ohms and 'High' for connection to highimpedance microphone inputs. Wired for low impedance as sup
plied. To change impedance, see sections on Impedance Selection and Connections.
Output Level
Open Circuit Voltage , at 1kHz
L -58.0 (1.3 dB mV
H -35.0 (17.6 dB mV
Polarity
Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3
Switch
Built-in magnetic reed on/off switch with lockplate. To lock switch in the ON position, remove screw on lockplate
and turn lockplate 180°. Reassemble and tighten screw.
Cartridge Shock Mount
Internal rubber vibration isolator
Swivel Adapter
Positive action, adjustable through 90° from vertical to horizontal, permits easy removal for handheld use, suitable
for mounting on stand with 5/8 in.-27 thread
