General Description  
Applications and Placement  
General Rules for Use  
The Shure Beta 98AMP is a compact, high-output, con-  
denser microphone for professional sound reinforcement  
and studio recording. An extremely uniform cardioid  
polar pattern provides excellent gain-before-feedback,  
off-axis rejection of unwanted noise, and performance in  
high sound pressure level (SPL) environments.  
Aim the microphone toward the desired sound source; angle unwanted sounds toward its null point.  
Use the fewest amount of microphones as practical to increase the Potential Acoustic Gain and prevent feedback.  
Follow the 3 to 1 Rule by spacing each microphone by at least three times the distance to its source to reduce  
Phase Cancellation.  
The Beta 98AMP features an integrated preamplifier with  
XLR connection, a flexible gooseneck, and is packaged  
with the A75M Universal Microphone Mount accessory  
for precision adjustments and minimal stage clutter. For  
use with drums, percussion, and other fixed-placement  
applications.  
Place microphones as far as possible from reflective surfaces to reduce Comb Filtering.  
When using directional microphones, work closely to the microphone for extra bass response to take advantage of  
Proximity Effect.  
Avoid excessive handling to minimize pickup of mechanical noise and vibration.  
Do not cover any part of the microphone grille, as this will adversely affect microphone performance.  
Add a windscreen when using the microphone outdoors.  
The following table lists the most common applications and placement techniques. Keep in mind that microphone tech-  
nique is largely a matter of personal taste; there is no one “correct” microphone position.

SUGGESTED MICROPHONE PLACEMENT  
TONE QUALITY  
Beta 98AMP/C-3PK: includes three Beta 98AMP  
microphones and three A75M Universal Microphone  
Mounts.  
Tom-Toms  
One mic on each tom or between a pair of toms, 2.5 to  
7.5 cm (1 to 3 in.) above drum heads.  
Medium attack; full, balanced  
sound.  
Remove bottom head and place a mic inside pointing up  
toward top drum head.  
Maximum isolation; full, bal-  
anced sound.  
Snare Drum  
Cymbals  
2.5 to 7.5 cm (1 to 3 in.) above rim of top head of drum.  
Aim mic at drum head.  
Most “snap” from drumstick.  
Features  
Close-mike with A75M mount, avoiding range of cymbal  
movement  
Maximum isolation; bright,  
with plenty of attack.  
Premier live performance microphone with Shure  
quality, ruggedness, and reliability  
NOTE: Before each use, make sure the cartridge is tightly secured on the microphone, as vibration and accidental hits  
with drumsticks may loosen it, resulting in signal loss.  
Uniform cardioid polar pattern for maximum gain  
before feedback and superior rejection of off-axis  
sound  
Positioning the Microphone  
Tailored frequency response shaped for drums and  
percussion  
The flexible gooseneck allows precise adjustments to the microphone without moving the mount.  
Note: Excessive twisting or forcing the gooseneck into extreme positions can permanently damage the microphone.  
Wide dynamic range for use in high SPL environments  
Compact design and integrated preamp reduce stage  
clutter and ease setup  
A75M Universal Microphone Mount  
Flexible gooseneck for precise placement and easy  
adjustments  
The Shure A75M mounts the Beta 98AMP on a variety of surfaces and instrument hardware. Reference the furnished  
A75M guide to correctly mount the microphone.  
Enamel coated metal construction and stainless steel  
inner grille resist wear and abuse

Load Impedance  
Accessories and Parts  
Furnished Accessories  
Maximum SPL capability, output clipping level, and dynamic range vary with the input  
load impedance of the preamplifier to which you connect the microphone. Shure recom-  
mends a minimum input load impedance of 1000 Ω. Most modern microphone preampli-  
fiers meet this requirement. Higher impedance results in better performance for these  
specifications.

Power Requirements  
This microphone requires phantom power and performs best with a 48 Vdc supply (IEC-  
61938). However, it will operate with slightly decreased headroom and sensitivity with  
supplies as low as 11 Vdc.  
Optional Accessories  
Most modern mixers provide phantom power. You must use a balanced microphone
