Specification Sheet

BETA 98A Instrument Microphone

General Description

The Shure Beta 98A is a compact, high-output, condenser microphone for professional sound reinforcement and studio recording. An ex- tremely uniform cardioid polar pattern provides excellent gain before feedback and off-axis rejection of unwanted noise. Its high sound pressure level (SPL) capability makes it useful for a variety of acoustic or amplified instruments including drums, piano, reed, wind, and strings.

Performance Characteristics

•Exceptional low-frequency reproduction

•Extremely high SPL handling

•High output level

•No crossover distortion

Shockmount Swivel Adapter

Use the following procedures to mount the Beta

98A on the swivel adapter:

1.Connect the microphone to the adapter.

2.Thread the cable through the C-clamp and slide the connector into the C-clamp until snug.

3.To reduce wear on the cable, snap it into the stress reliever clip leaving 5 to 7 cm (2 to 3 inches) of slack on the connector side.

Interconnecting Cable

The supplied cable connects the BETA 98A to the preamplifier. If necessary, up to 23 m (75 ft) of cable can be used between the microphone and preamplifier without signal loss.

A98D Drum Mount

The Shure A98D mounts the Beta 98A on a drum or cymbal stand. Reference the furnished A98D guide to correctly mount the microphone.

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.
