4 Using the Microphone

Double bass:

•Align the microphone with one of the f holes from a distance of about 16 inches (40 cm).

•If you need to record the double bass together with an ensem- ble, place the microphone closer to the instrument and set the polar pattern to hypercar- dioid (turn the polar pattern se- lector one notch CW from cardioid ( )) to prevent leak- age from other instruments into the bass microphone.

Cello/technique 1:

• Refer to “Double bass” above.

Cello/technique 2:

•Use a close-in microphone as

in technique 1 above plus a distant microphone.

•Set the level of the close-in microphone approx. 20 dB lower than the distant mic level.

We recommend using two micro- phones:

•Place one PERCEPTION 820 TUBE 8 to 12 inches (20 to 30 cm) away from the guitar and aim at the sound hole.

•Aim a small-diaphragm micro- phone (e.g., a C 451B) at a point near the bridge from a distance of about 3 1/2 feet (1 m) or at the body from a point below and to the rear of the instrument.

We recommend using two micro- phones:

•Place mic 1 above and to one side of the player (to reduce blowing noise) and align it with the player's mouth

•Aim mic 2 at the instrument from the side.

•Refer to fig. 14. If you prefer to use a single microphone, place the microphone about 7 to 8 1/2 feet (2 to 2.5 m) above the floor and aim as mic 1 above.
