Audix SCX1-C User manual

SCX1-C
OVERVIEW:
Designed, machined, assembled and tested by Audix in the USA, the SCX1-C is
a professional studio cardioid condenser microphone designed for a wide variety
recording, broadcast, and live sound applications. Known for its sensitivity, pin-
point accuracy, low prole, and consistency, the SCX1-C is also available with
hypercardioid (model SCX1-HC) or omnidirectional (model SCX1-O) capsules.
With a smooth uniform frequency response from 40 Hz - 20 kHz, the SCX1-C
is very consistent when responding to on and off-axis signals, and exhibiting
excellent phase coherence and minimal proximity effect. The SCX1-C is
characterized with a wide cardioid polar pattern; this, coupled with the high output
and sensitivity of the microphone, makes the SCX1-C an ideal choice for miking
overhead, room ambience, orchestral sections, stringed instruments, piano, vibes,
and sound effects.
Other features include a 21 mm gold vapor capsule miniaturized electronics,
and an extremely small footprint. The SCX1-C will handle sound pressure levels
of 130 dB and will provide up to 20 dB of ambient noise rejection. In addition
to acoustical instruments, the SCX1-C is an excellent choice for group vocals,
speech, or foley work.
The SCX1, which is manufactured to exacting standards and tight tolerances,
features a precision machined brass body, interchangeable capsules, black e-coat
nish, laser etched model and serial number, Switchcraft ® XLR connector, and
includes a heavy duty nylon clip.

ARCHITECTS AND ENGINEERS SPECIFICATIONS:
The microphone shall be of the condenser type with a modular threaded capsule available in
cardioid, hypercardioid, and omnidirectional polar patterns. 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 at 1 kHz. The microphone shall have a maximum
SPL level of 130 dB with a THD of 0.5%. The microphone shall have a capsule housing and body
machined of brass with dimensions of 19 mm diameter at the base, 21 mm in diameter at the widest
point on the grill and 104 mm in length. The microphone shall be the Audix SCX1-C.
OPERATION:
The SCX1 is a low impedance microphone and should be plugged into a “mic level” input on your
console, mixer, or recording device. The SCX1-C 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 is 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 SCX1 is a world class recording microphone with very high output and sensitivity. The SCX1-C
and SCX1-O generally are not intended to be used at very close range, especially with instruments
that produce high sound pressure levels.
For acoustic instruments: In general, the working range should be from 1-2 feet, depending on the
instrument and room acoustics. For voice, the minimum distance is 8-10 inches for a single voice.
For group vocals: The distance should be 2-3 feet.
For drum overheads: The microphones should be in a vertical position and placed above the
cymbals by 1 ½-2 feet and equidistant from the snare.
For high hat: Use the SCX1-HC and place 4-6 inches above the outer rim of the high hat cymbal.
For bottom snare: Place the SCX1-C or SCX1-HC 3-4 inches beneath the snare aimed up towards
the snares.
For piano: For live performance and live recordings, it is sometimes required to use the short stick
or closed lid in order to minimize the surrounding instruments from “bleeding” into the piano mics. In
these cases, it is suggested to use the Audix DFLEX mounting clips which enable the SCX1 to be
mounted right on to the rail of the piano. The mics can be positioned horizontal to the sound board,
typically one towards the front of the keyboard and one towards the rear of keyboard towards the
bass strings.

SERVICE AND WARRANTY:
This microphone is under warranty for
a period of 3 years from any and all
manufacturing defects. Should your
microphone fail in any way, please

CARE AND MAINTENANCE:
The SCX1-C is manufactured to exacting
specs with road worthy 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.
