GENERAL

The Model SM7B dynamic microphone has a smooth, flat,

wide-range frequency response appropriate for music and

speech in

all professional audio applications. It features excel-

lent shielding against electromagnetic hum generated by com

puter monitors, neon lights, and other electrical devices. The

SM7B

has been updated from earlier models with an improved

bracket design that offers greater stability. In addition to its

standard

windscreen, it also includes the A7WS windscreen

for close-talk applications.

Features

• Flat, wide-range frequency response for clean and natural

reproduction

of both music and speech

• Switchable bass rolloff and mid-range emphasis (presence

boost)

settings

• Shielded against broadband interference from computer

monitors

and other electrical devices—excellent rejection

electromagnetic hum

• Internal “air suspension” shock isolation virtually eliminates

mechanical

noise transmission

• A7WS windscreen included for close-up vocals or narration

• Swiveling bracket with integrated stand adapter for easy

mounting and precise microphone positioning

• Cardioid polar pattern, uniform with frequency and symmet-

rical

about axis, to provide maximum rejection and mini-

mum

coloration of off-axis sound

• Rugged construction and excellent cartridge protection for

outstanding reliability

APPLICATIONS

The exceptional performance and unique features of the

SM7B

make it the outstanding choice for such applications as:

• Recording Studio—Instrumental and Vocal

• Location Recording

• Motion Picture and Television Scoring

• Television Talk Shows and News Desks

• Radio Announcing and Production

• Narration

WINDSCREEN

Use

the standard windscreen for general voice and instru-

mental

applications. Use the supplied A7WS windscreen for

close-talk applications, such as voice overs or radio an-

nouncements, as it offers maximum protection from plosive

breath

noise and creates a warmer, more intimate sound.

To install the A7WS, follow these instructions:

1. To avoid tearing the windscreen during removal, grip it

fro

m the plastic ring and the base and remove by gently

pulling and twisting.

2. If desired, adhere the supplied velcro strips around the mi-

crophone grille, approximately one

inch from the base of

the

grille (as shown above) to hold new windscreen in

place.

3. Install the A7WS windscreen by stretching over the velcro

strips

, then squeezing at the base of the windscreen to ad-

here to the velcro. No velcro strip inside the windscreen

needed, as the windscreen itself adheres to the velcro.

To remove, grip at the base of the windscreen and pull

while twisting.

MOUNTING INSTRUCTIONS

e SM7B can be mounted on a microphone stand or hung

fro

m a boom. It is shipped in the boom mounting configuration

(see Figure 1).

To set up the SM7B in the microphone stand

mounting

configuration (see Figure 2), proceed as follows:

1. Remove tightening nuts on the sides (see Figure 7).

2. Remove the fitted washers, the lock washers, the outer

brass

washers, and the brass sleeves.

3. Slide the bracket off the microphone. Be careful not to lose

the

washers still on the microphone.

4. Invert and rotate the bracket. Slide it back onto the bolts

over

the brass and plastic washers still on the microphone.

e bracket should fit so the XLR connector faces the rear

the microphone, and the Shure logo on the back of the

microphone

is right-side up.

5. Replace the brass sleeves. Be sure they are seated proper-

within the inner washers.

6. Replace the outer brass washers, the lock washers and the

fitted

washers.

7. Replace the tightening nuts and tighten the microphone at

the desired angle.

NOTE: If

the tightening nuts do not hold the microphone

position, one or both of the brass sleeves may not be

properly

seated within all the washers.
