SM7B
Cardioid Dynamic Vocal Microphone
General Description
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 excellent shielding against electromagnetic hum
generated by computer monitors, neon lights, and other electrical devices.
In addition to its standard windscreen, it also includes the A7WS windscreen
for close-talk applications.
The SM7B is an outstanding choice for the following applications:

•
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

Mounting Instructions
The SM7B can be mounted on a microphone stand or hung from a boom. It
is shipped in the boom mounting configuration. To set up the SM7B in the
microphone stand mounting configuration, proceed as follows:
1. Remove tightening nuts on the sides.
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. The bracket should fit so
the XLR connector faces the rear of 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 properly 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 in position, one
or both of the brass sleeves may not be properly seated within all the
washers.

To install the A7WS, follow these instructions:
Windscreen
Use the standard windscreen for general voice and instrumental applications.
Use the supplied A7WS windscreen for close-talk applications, such as voice
overs or radio announcements, as it offers maximum protection from plosive
breath noise and creates a warmer, more intimate sound.
1. To avoid tearing the windscreen during removal, grip it from the plastic
ring and the base and remove by gently pulling and twisting.
2. If desired, adhere the supplied velcro strips around the microphoen grille,
approximately one inch from the base of the grille (as shown) 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 adhere to the velcro. No
velcro strip inside the windscreen is needed, as the windscreen itself
adheres to the velcro. To remove, grip at the base of the windscreen and
pull while twisting.
