SPECIFICATIONS: ARCHITECTS AND ENGINEERS SPECIFICATIONS:
The microphone shall be of the dynamic type available in a cardioid polar pattern. The nominal
output impedance shall be equal to 250 ohms at 1 kHz. The microphone shall have a sensitivity
at of 1.7 mV/Pa at 1 kHz. The microphone shall have a maximum SPL level of ≥135 dB with
THD of 0.5%. The microphone body shall be of die cast zinc alloy. The dimensions shall be 22
mm in diameter at the base, 43 mm in diameter at the widest point and 118 mm in length. The
microphone shall be the Audix F12.
OPERATION:
The F12 is a low impedance microphone and should be plugged into a “mic level” input on your
console, mixer, or recording device. Please note that the F12 does not require phantom power
and will not be effected in any way by phantom power should it be running simultaneously while
the microphone is in operation. Avoid plugging or unplugging the microphone from the PA system
unless the channel is muted or the volume of the system turned down. Failure to do so may result
in a loud “popping” noise which could seriously the speakers in the PA system.
USER TIPS:
The F12 has a tight (cardioid) pick-up pattern in order to help minimize the sound from other
instruments on stage from “bleeding” into the microphone. For this reason, the F12 is very
effective for miking drums and percussion and in capturing the sound of each component of the
kit.
Drums, hand percussion: As a general rule, the bottom of the F12 should be 1-2 inches above
the head of the drum and pointed towards the center. For more “ring” pull the mic back towards
the rim; for less ring and more overtones, position the mic 1-2 inches inside the ring; for more
attack, place the mic very close to the head; for more overtones and decay move the mic further
away from the head.
Guitar cabs: The F12 can be placed within 1-2 inches of the grill cover at a 90 degree angle
pointing directly into the speaker. If the mic is placed closer to the edge of the speaker, you will
minimize the higher frequencies and get a warmer, fatter tone. To capture more highs, move the
mic closer towards the center of the speaker, but avoid the middle of the speaker.
Horns: Place the F12 within 1-2 inches of the bell, especially when on a stage with drums, bass,
guitar, etc.

CARE AND MAINTENANCE:
The F12 is manufactured to exacting specs with
roadworthy construction. However, the capsule
is highly sensitive and should be handled with
care. Avoid extreme temperatures and be sure
to store your microphone in the pouch provided
when not in use. Moisture of any kind can
adversely affect the sound and performance of
your microphone.
