Acoustic Guitar - Crown SASS Application Manual

• For maximum gain-before-feedback and isolation,
use a CM-310A with your lips touching the metal
grille. The CM-310A Differoid® has more gain-
before-feedback than any mic you can buy, so it
really helps vocals stand out over a loud instrumen-
tal background.
• Vocalists who move around while playing often
prefer a headworn mic. An excellent choice for this
is the Crown CM-311A. It is worn with lips touching
the microphone, and offers extremely high gain-
before-feedback and isolation. For less critical
situations, use a CM-312A. It is smaller and lighter
than the CM-311A, and the mic is at the side of the
mouth.

Recordings (Figure 4):
• Attach a GLM-100 to the guitar sound board,
halfway between the bridge and the sound hole,
near the low E string.
• Place a CM-700 or CM-150 6 to 12 inches from
where the finger board joins the body. For stereo,
add another mic the same distance from the bridge.
Sound Reinforcement:
• Tape a GLM-100 inside the guitar onto the surface
nearest the performer, so that the mic can see the
sound hole. Equalize for the desired tone quality.
• Place a CM-700 a few inches from the sound hole
and roll off the excess bass at your mixer.
Sax (Figure 5):
Recording:
• Place a CM-700 or CM-150 18 inches away, a few
inches above the bell, toward the player's right side.
• Clip a GLM-UM to the bell, and attach a GLM-100
to the clip about 4 inches from the bell so that it can
see the tone holes.
Sound Reinforcement:
• Place a CM-200A or CM-700 just above the bell,
aiming at the tone holes.
• Clip a GLM-UM to the bell, and attach a GLM-100
to the clip just above the ball, aiming at the tone
holes.
Electric guitar or bass
Recorded Direct:
• For a clean sound, plug directly into an unbalanced
line input or use a direct box. For a distorted sound,
plug into a guitar signal processor (such as the
Rockman™), then into a mixer input.
Electric guitar amp (Figure 6):
Recording/Reinforcement:
• Place a CM-200A 1 to 12 inches from the center of
one of the speaker cones. For more bass, place the
mic close. For the brightest tone, place the mic near
the center of the speaker cone. For a mellower tone,
place the mic near the edge of the speaker cone.
