C 426B
Stereo Condenser Microphone
Description
The AKG Model C 426 B is the direct descendent of
AKG's original C 24 and the more recent C 422 stereo
microphone models. New technology has improved the
dynamic range, self noise, sensitivity, linearity, frequency
response between channels and crosstalk. The C 426 B
contains two 25 mm gold sputtered dual capsule sets
arranged in a coincident pair. The entire microphone head
assembly can be rotated 45° relative to the shaft, allowing a
quick changeover from M-S to X-Y modes of stereo
recording. Additionally, the upper capsule assembly can be
rotated 270° relative to the lower one, providing utmost
flexibility in stereo pickup angle. The polar patterns for both
microphone sections are separately controlled at the S 426
remote powering unit. The change in polar pattern is made
noiselessly and may be made during recording. The body of
the microphone contains a switchable -10 dB pre-attenuation
pad and a bass cut of 12 dB per octave below 75 Hz. Two
narrow angle LEDs are aligned with the primary axis of both
capsule sections and enable the operating engineer to verify
the precise orientation of each capsule. The microphone is
attached to the S 426 control unit via a multi-pin, 66 ft.
(20 meter) cable. The signal outputs on the S 426 are
XLR-M, and the unit operates on phantom power over the
nominal range of 9 to 52 volts.
