Shure Microphone 55S User Manual

UNIDIRECTIONAL DYNAMIC MICROPHONES  
General: The Models 55S and 55SW are extremely  
rugged microphones built to provide wide range re-  
production of music and voice. The Cardioid unidirec-  
tional characteristic of the microphones provides  
highly satisfactory operation under adverse acoustic  
conditions where omnidirectional microphones may  
not operate properly. These microphones can be used  
closer to loudspeakers than usual, without creating  
feedback problems.  
The Models 55S-Gold and 55SW-Gold are identical  
to the Models 55S and 55SW respectively except  
Models 55S-Gold and 55SW-Gold have gold finish.  
The Models 55S and 55SW are ideal for high quality  
public address, theatre-stage sound systems, remote  
broadcasting recording applications and other sound  
applications such as those used in hotels, stadiums,  
and public auditoriums.  
The microphones feature:

Guarantee: This Shure product is guaranteed in normal  
use to be free from electrical and mechanical defects  
for a period of one year from the date of purchase.  
Please retain proof of purchase date. This guarantee  
includes all parts and labor.  
n A strong detachable cable especially selected  
for good shielding from “hum” pickup.  
n Very rugged mechanical design for reliable oper-  
ation under severe conditions of use.  
n A self-tensioning swivel permits tilting through  
45° forward and 80° backward.  
Shipping Instructions: Carefully repack the unit and  
return it prepaid to the factory. If outside the United  
States, return the unit to your dealer or Authorized  
Shure Service Center for repair. The unit will be  
returned to you prepaid.  
The Models 55S and 55SW are multi-impedance for  
connecting into microphone inputs rated at 25 to 50  
ohms, 150 to 250 ohms, or into high impedance micro-  
phone inputs.  
MODELS 55S AND 55SW  
The low impedances are recommended where long  
cable lengths are required or under conditions of  
severe hum disturbance. The permissible cable length  
is practically unlimited, since neither response nor  
level is appreciably affected. For use with high im-  
pedance amplifiers. Shure Model A95A Line Matching  
Transformer is available for coupling the low imped-  
ance line to the amplifier input.  
ARCHITECT’S SPECIFICATIONS  
The microphone shall be Shure Model 55S, 55SW,  
or equivalent. The microphone shall be a moving coil  
type microphone with a frequency range of 50 to  
15,000 Hz. This unit shall have a Cardioid horizontal  
polar characteristic. The cancellation at the sides shall  
be approximately 6 db and the cancellation at the rear  
shall be in the order of 15 db. The microphone shall  
be equipped with a three-position impedance change  
switch for adjusting the microphone rating impedance  
to 38 ohms, 150 ohms or 40.000 ohms. The Model  
55SW shall have a built in “ON-OFF” switch. The  
Model 55S shall have no “ON-OFF” switch. The mi-  
crophone rating Gm (Sensitivity) at 1,000 Hz. shall be  
within ± 3 db of the following levels:  
Impedance Selection  
Selection of the various impedances is accomplished  
by changing the position of the switch at the rear of  
the microphone. The switch positions are marked “L”  
for low impedance (25-50 ohms), “M” for medium  
impedance (150-250 ohms), and “H” for high imped-  
ance (35,000 ohms).  
When using the microphone in low impedance, the  
black and white conductors are the “hot” conductors  
for balanced line connections to a standard low or  
medium impedance input amplifier; the shield lead is  
connected to the chassis or amplifier ground.  
When using the microphone in high impedance, the  
white conductor is the “hot” conductor for connection  
to a high impedance amplifier; the black conductor  
and the shield are connected to the chassis or am-  
plifier ground.  
“L” Position of switch ............................ - 148.0 db  
“M” Position of switch............................ - 148.5 db  
“H” Position of switch............................ - 151.5 db  
EIA Standard SE-105 August 1949  
The microphone shall be provided with a swivel and  
it shall have a detachable cable connector capable of  
connection to a two-conductor shielded cable. The  
microphone will mount on stand having 5/8”-27 thread.

The overall dimensions shall be 7 /8 (187.3 mm) ± ¼  
1
inches in height, 2-3/16 (55.6 mm) ±  
/
inches in  
8
width, and 3-1/16 (77.8 mm) ± 1/8 inches in depth.
