GENERAL
The Model 55SH Series II provides the Shure classic
UNlDYNE
. II design coupled with modern acoustic compo-
nents to meet today’s performance standards. This micro-
phone is excellent for vocal pickup with its characteristic
Shure presence peak.
The 55SH Series II has a cardioid (unidirectional) polar
pickup pattern that minimizes sound pickup from the rear of
the microphone. This allows the Model 55SH Series II to be
used in close proximity to loudspeakers without creating
feedback problems, and it can perform under adverse
acoustic conditions where omnidirectional microphones
cannot.
The 55SH Series II has a low-impedance balanced output
designed for connection to microphone inputs rated at 75 to
300 ohms. The microphone features a cartridge shock
mount to reduce stand noise, an On/Off switch, and an at-
tached, self-tensioning,
5/8”–27 thread swivel mount.
This microphone is ideal for public address or theater–
stage sound systems, as well as for broadcasting, record-
ing, and other sound applications where a stand-mounted
microphone with a classic look is desirable.
