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.
