BETA 98H/C

Cardioid Condenser Microphone

General Description

The Beta 98H/C miniature cardioid condenser micro-

phone clamps onto the bell of wind instruments or onto

the rim of percussion instruments. The integrated goose-

neck and ratcheting swivel joint allows the mic to be

easily positioned and secured, and an isolation shock-

mount reduces the transmission of instrument vibrations.

A gooseneck angle brace is included to provide better

retention of the desired microphone placement.

Featuring a highly consistent cardioid polar pattern, the

Beta 98H/C provides high gain before feedback and

smooth off-axis rejection. It's ability to handle extremely

high sound presure levels (SPL) makes it ideal for live

sound reinforcement on a variety of instruments.

Features

• Premier live performance microphone with Shure

quality, ruggedness, and reliability

• Uniform cardioid pick-up pattern for maximum gain

before feedback and excellent rejection of off-axis

sound

• Tailored frequency response specifically shaped for

open, natural sound reproduction

• Wide dynamic range for use in high sound pressure

level SPL environments

• Adjustable gooseneck, angle brace and ratcheting

swivel joint allow for optimal microphone positioning

• Compact, lightweight construction provide a low

degree of visibility

• Interchangeable microphone cartridges with different

polar patterns are available

• Snap-fit foam windscreens stay in place, minimizing

wind noise

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.

• For better gain before feedback, use fewer

microphones.

• Keep the distance between microphones at least

three times the distance from each microphone to its

source ("three to one rule").

• Place microphones as far as possible from reflective

surfaces.

• Add a windscreen when using the microphone

outdoors.

• Avoid excessive handling to minimize pickup of

mechanical noise and vibration.

Applications And Placement

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

Reed Instruments Place microphone a few inches from and aiming

into bell.

Bright, minimizes feedback and

leakage.

Brass & Woodwinds Brass: 30 to 90 cm (1 to 3 ft.) away, on-axis with

bell of instrument.

Bright, clear sound.

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.

Avoiding Pickup of Unwanted

Sound Sources

A cardioid microphone has the greatest sound rejection

at the rear of the microphone. Place the microphone

so that unwanted sound sources, such as monitors

and loudspeakers, are directly behind it. To minimize

feedback and ensure optimum rejection of unwanted

sound, always test microphone placement before a

performance.

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.

Most modern mixers provide phantom power. You must

use a microphone cable: XLR-to-XLR or balanced

XLR-to-TRS.

Wiring Diagram

Proximity Effect

Directional microphones progressively boost bass frequencies as the microphone is

placed in closer proximity to the source. This phenomenon, known as proximity effect,

can be used to create a warmer, more powerful sound.
