Audix Corporation 9400 SW Barber Street, Wilsonville, OR 97070
ARCHITECTS AND ENGINEERS SPECIFICATIONS:
The microphone shall be of the condenser type with a cardioid polar pattern. The microphone shall operate
on 48-52 volts phantom power and the nominal output impedance shall be equal to 200 ohms at 1 kHz. The
microphone shall have a sensitivity of 14 mV / Pa and shall have a maximum SPL level of ≥145 dB with a THD
of 0.5% when the -10 dB pad is engaged. The microphone shall have a fine steel mesh grill and a brass body
50 mm in diameter and 163 mm in length. The microphone shall be the Audix CX-112.
OPERATION:
The CX-112 is a low impedance microphone and should be plugged into a “mic level” input on your console,
mixer, or recording device. The CX-112 requires phantom power and will NOT operate without phantom power
voltage (48 Volts recommended) which is available on most professional mic preamps and mixing devices. If
phantom power is not available on your equipment, you will have to procure a phantom power supply (such
as the Audix APS-2).
Avoid plugging or unplugging the microphone from a 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 damage
the speakers in the PA system.
USER TIPS:
The correct side:
Note that the front of the microphone element is on the same side as the printing. This side
of the microphone should be facing towards the sound source.
The Switches:
The CX-112 is equipped with 2 slider switches that control the -10 dB pad and bass roll-off. They
are located directly above the Audix logo on the front of the mic.
-10 dB Pad:
The -10 dB switch is located above the Audix logo and to the right. When the switch is all the way
to the left, (the 0 dB position), it is NOT engaged, and the mic is at its normal output level. The -10 dB pad allows
you to change the sensitivity (output level) of the microphone right at the capsule. This is much more effective
than padding the mic at the preamp stage at the console or mixing device. The net result is the ability to record
very high sound pressure levels before distortion.
Bass Roll-Off:
This feature allows you to change the frequency response of the CX-112 and gently diminish
the bass response from 300 Hz and below. The bass roll-off (also referred to as “attenuation”) is the switch
on the left-hand side above the Audix logo. When the switch is all the way to the left (the “Flat” position), the
bass roll-off is NOT engaged. In some cases, you will want to roll-off or filter out the bass frequencies from
your recording or performance. These frequencies can be controlled by external EQ, however, the advantage
of having them on the microphone is it is much cleaner to control these frequencies at the capsule level. In the
case of live recording, the bass roll-off will help to eliminate unwanted boominess or rumble coming from other
instruments on the stage (for example, the bass and bass drum). In the case of a recording environment, it will
depend on the instrument or voice being recorded. The roll-off can help to eliminate plosives or popping from a
vocal or it may be utilized to clean up the excessive bass frequencies from certain instruments. In any case, it
is recommended to try “with” and “without” roll-off before making any final decisions.

CARE AND MAINTENANCE:
The CX-112 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.
