Audix CX112B User manual

CX112B
OVERVIEW
The CX112B is a large diaphragm condenser microphone with a contemporary design
and excellent performance characteristics. It is an exceptional tool for professional
audio production, project studios and live stage performances. Delivering a smooth,
uniform frequency response from 20 Hz - 20 kHz, the CX112B offers a rich, full bodied
sound delivered by its 35 mm capsule.
The CX112B is equipped with a bass roll-off filter to help eliminate rumble in the
lower frequencies and a -10 dB pad for use in higher SPL up to 145 dB. Applications
would include a wide variety of acoustic instruments, vocals, string sections, guitar,
ensembles, guitar cabinets and ambient room miking.
Designed with low noise preamp circuitry, the CX112B operates on phantom power.
For optimum results, the CX112B should be used with a high quality mic preamplifier
and microphone cable.

SPECIFICATIONS
CX112B
ARCHITECT AND ENGINEER SPECIFICATIONS
The microphone shall be of the condenser type with a cardioid polar
pattern. The microphone shall operate on 48 volts phantom power
and the nominal output impedance shall be equal to 120 ohms at 1
kHz. The microphone shall have a sensitivity of 18 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 165 mm in length.
OPERATION AND MAINTENANCE
The CX112B is a low impedance microphone and should be plugged into
a “mic level” input on your console, mixer, or recording device. The CX112B
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, use a phantom power supply such as the Audix APS2.
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, studio monitors and headphones.
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 CX112B is equipped with two 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 on the console or mixing device. The net result is the ability to record
very high sound pressure levels before distortion.
Bass Roll-O: This feature allows you to change the frequency response
of the CX112B 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.
