General Description
The Shure Beta 98AMP is a compact, high-output, condenser 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.
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.
Applications and Placement
General Rules for Use
• 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.
• 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.
Variations
• Beta 98AMP/C: Beta 98AMP microphone furnished

The following table lists the most common applications and placement techniques. Keep in mind that microphone technique is largely a matter of personal taste; there is no one “correct” microphone position.
APPLICATION SUGGESTED MICROPHONE PLACEMENT TONE QUALITY
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.
Remove bottom head and place a mic inside pointing up
toward top drum head.
Snare Drum 2.5 to 7.5 cm (1 to 3 in.) above rim of top head of drum.
Aim mic at drum head.
Cymbals Close-mike with A75M mount, avoiding range of cymbal
movement
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.
Medium attack; full, balanced
sound.
Maximum isolation; full, balanced sound.
Most “snap” from drumstick.
Maximum isolation; bright,
with plenty of attack.
Positioning the Microphone
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.
A75M Universal Microphone Mount
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.
