The Beta 98H/C miniature cardioid condenser microphone clamps onto the bell of wind instruments or onto the rim of percussion instruments. The integrated gooseneck 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 pressure levels (SPL) makes it ideal for live sound reinforcement on a variety of instruments.
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. |
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.
Recommended Loudspeaker Locations for Cardioid Microphones
Unidirectional (cardioid) microphones progressively boost bass frequencies by 6 to 10 dB below 100 Hz when the microphone is at a distance of about 6 mm (1/4 in.) from the sound source. This phenomenon, known as proximity effect, can be used to create a warmer, more powerful sound. To prevent explosive low frequency sound during close-up use, the bass response gradually rolls off. This provides greater control and helps the user take advantage of proximity effect.
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 balanced microphone cable: XLR-to-XLR or XLR-to-TRS.
