GENERAL

The Model 55SH Series II provides the Shure classic
UNlDYNE
nents to meet today’s performance standards. This micro­phone 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 at­tached, self-tensioning,

This microphone is ideal for public address or theater–
stage sound systems, as well as for broadcasting, record­ing, and other sound applications where a stand-mounted
microphone with a classic look is desirable.

POLARITY

To test two microphones and their cables for common 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 they have com­mon polarity. If the sound level drops drastically, or if a dead
spot is found, when talking between the two microphones,
either the microphones or their cables have different polari­ty. All cables and microphones can be tested in this manner
to ensure that they have common polarity.

To reverse the polarity of a low–impedance microphone
cable, use either a Shure A15PRS Switchable Phase Re­verser or interchange the wires connected to pins 2 and 3 of
the connector. To reverse the polarity of a microphone, inter­change the cartridge leads (see Figure 4.) This should be
performed by your dealer, the Shure Factory Service De­partment, or other qualified service personnel.
