BETA98A -- Miniature Cardioid Condenser

Microphone

General Description

The Shure Beta 98A 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 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.

Variations

• Beta 98A/C includes microphone, 7.6 m (25 ft) light-weight interconnect cable, preamplifier, and RK282 shock-

mount swivel adapter.

• Beta 98AD/C includes microphone, 4.6 m (15 ft) heavy-duty interconnect cable, preamplifier, and A98D micro-

phone drum mount.

Performance Characteristics

• Exceptional low-frequency reproduction

• Extremely high SPL handling

• High output level

• No crossover distortion

Features

• Premier live performance microphone with Shure quality, ruggedness, and reliability

• Uniform cardioid pick-up pattern for maximum gain before feedback and superior rejection of off-axis sound

• Tailored frequency response specifically shaped for drums, percussion, reeds, and horns

• Compact design reduces stage clutter

• Wide dynamic range for use in high SPL environments

• Optional A98D mount is unobtrusive, versatile, and easy to adjust

• Enamel-coated metal construction and stainless steel inner grille resist wear and abuse

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.

Shure Incorporated Applications General Rules for Use • Do not cover any part of the microphone grille with your hand, as this will adversely affect microphone performance. • Aim the microphone toward the desired sound source (such as the talker, singer, or instrument) and away from unwanted sources. • Place the microphone as close as practical to the desired sound source. • Work close to the microphone for extra bass response. • Use only one microphone to pick up a single sound source.

Shure Incorporated Application Suggested Microphone Place ment Tone Quality Woodwinds: 2.5 to 15 cm (1 to 6 in.) away, on-axis with bell of instrument. Bright, clear sound. Bell of instrument 90° off-axis from front of mic. Softer, mellow sound. 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.

Shure Incorporated Load Impedance Maximum SPL capability, output clipping level, and dynamic range vary with the input load impedance of the preamplifier to which the microphone is connected. Shure recommends a minimum input load impedance of 1000 Ohms. Most modern microphone preamplifiers 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).
