or amplified instruments including drums, piano, reed, wind, and strings.

Applications

General Rules for Use

• Do not cover any part of the microphone grille with your hand, as this will adversely affect microphone perfor-

mance.

•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.

•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 Place

ment 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.

sound.

Remove bottom head and place a

mic inside pointing up toward top

drum head.

sound.

Snare Drum 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.

Cymbals Close-mike with an A98D mount

for maximum isolation, but place

out of cymbal movement range.

Bright, with plenty of attack.

Brass & Woodwinds Brass: 30 to 90 cm (1 to 3 ft.)

away, on-axis with bell of instru-

ment Tone Quality

Woodwinds: 2.5 to 15 cm (1 to 6

in.) away, on-axis with bell of in-

strument.

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.

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.
