AT8024
Stereo/Mono Camera-Mount Microphone
Features
Description
The AT8024 is a xed-charge condenser microphone designed for use with DSLR
and other video cameras. The microphone offers the exibility of mono and mid-
side stereo modes for high-resolution audio in any environment.
The microphone is powered by a included single 1.5V AA battery. The AA battery
provides optimal performance with high max SPL. A red/green LED power
indicator, located on the top of the unit, illuminates green when the microphone is
sufciently powered and red when battery power is low. The AT8024 is equipped
with a three-position input pad that allows for attenuation adjustment. The
microphone also features an 80 Hz high-pass lter switch that permits choice of
at response or low-frequency roll-off to reduce the pickup of undesired ambient
noise, room reverberation and mechanically coupled vibrations.
The microphone is enclosed in a rugged housing and includes an integral
shoe mount that fits most camera shoes. Two rubber shock mounts isolate
the microphone from vibration and mechanical camera noise. The microphone
includes a permanently attached cable with a 3.5 mm L-type stereo plug output. A
clip on the shoe mount holds the cable, relieving tension and preventing vibration
noise.
A windscreen and fuzzy windscreen are also included.
Installation and Operation
The mode switch located on the top of the unit allows user to select between
mono and internally matrixed mid-side stereo modes.
Mono Operation: In Mono mode, the microphone uses its line-cardioid element
exclusively to provide excellent off-axis rejection. This is ideal for recording
interviews, dialogues or sound sources that might otherwise be drowned out in
noisy environments.
Mid-Side Stereo Operation: In Stereo mode, the microphone provides internally
matrixed mid-side stereo, delivering wide, life-like stereo sound. Locating the
AT8024 nearer the sound source will enhance the apparent width of the stereo
image, while decreasing room ambience. Moving the microphone away from the
sound source will narrow the stereo image and provide more Mroom soundr The
Stereo mode is well-suited for sporting events and other active situations where
sonic realism is desired.
The integral shoe mount slides into the shoe of most cameras. Tighten the nut
on the shoe mount to hold the microphone securely in place. The shoe mount is
also equipped with a strain-relief clip for the cable. Insert the cable into the clip to
reduce wear on the cable and eliminate noise from cable vibration.
To install the battery, press the PUSH button located on the side of the unit. This
will eject the battery compartment. Insert a 1.5V AA battery according to the
polarity markings in the compartment, then press the compartment back into the
body of the unit so that it clicks closed. When the mode switch is moved from
the Off position to Mono or Stereo, the LED power indicator will illuminate green,
showing that the microphone has power. Replace or recharge the battery when
the LED illuminates red.
The attenuation can be adjusted by using the three-position input pad switch (-20
dB, -10 dB, 0 dB) located on the top of the unit. Adjust according to the volume of
the sound source: -20 dB for the loudest sounds, 0 dB for the softest. The 80Hz
high-pass lter switch is located along side the input pad switch. To engage the
high-pass lter, slide the switch toward the "bent" line.
Since even slight or unexpected winds can adversely affect audio recordings, it is
best to use the microphone with the supplied windscreen or, when recording in
especially windy environments, the supplied fuzzy windscreen.
Avoid leaving the microphone in the open sun or in areas where temperatures
exceed 43° C for extended periods. Extremely high humidity should also be
avoided.
