C 426 B 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. Specifications Transducer Principle: Condenser, externally polarized Frequency Range: 20–20,000 Hz Polar Pattern: Sensitivity at 1,000 Hz: Cardioid, omnidirectional, figure-eight and six intermediate positions 11 mV/Pa ^ = -39 dBV Equivalent Noise Level: 14 dB-A Sound Pressure Level for 0.5% THD: 132 dB (142 dB at -10 dB) S/N Ratio (A-weighted): 80 dB Electr. Impedance: < 200 ohms Load Impedance: > 1,000 ohms Power Requirement: 9-52 volts nominal Phantom powering Connector on S 426: Two 3-pin XLR type Bass roll-off: 12 dB/octave below 75 Hz Pad: -10 dB Finish: Non-reflective black Size: Dia 1.65/1.3 in. (42/33 mm) Length 9.25 in. (235 mm) Net/Shipping Weight: 1.04 lbs. (0.47 kg)/11.2 lbs. (5.1 kg) Included Accessories: H 15/33 Suspension mount/stand adapter, W 426 Foam windscreen, MK 42/20 66 ft. (20 meter) cable, S 426 Remote control unit, Carrying case Optional Accessories: B 18 Battery power supply (for one channel only) Features • One of the world's most celebrated stereo condenser microphones • Large 25 millimeter gold sputtered diaphragm format optimized for studio applications • Two sets of dual diaphragms for multiple polar patterns arrayed at various angles • High acoustic level capability (132 dB-SPL for 0.5% THD) • Low self noise (14 dB-A) Architects and Engineers Specifications The stereo microphone shall provide dual capsules, each capable of at least nine operating patterns (omnidirectional, cardioid, figure-eight, and six intermediate positions) and mutually adjustable over a total operating angle of 270 degrees. Remote switching between adjacent patterns shall be silent, thus enabling pattern changes during recording operations. The microphone shall provide for switchable 10 dB pre-preamp attenuation and switchable bass cut of 12 dB/octave below 75 Hz. Each stereo section of the microphone shall provide a means for precise on-axis alignment at a distance (e. g., by means of a narrow angle LED). The self noise level of each microphone section shall be no greater than 14 dB (A-weighted), and the sound pressure level at which the microphone's total harmonic distortion reaches 0.5 % shall be no lower than 132 dB. The microphone shall operate on phantom power, supplied to the remote control unit, over the nominal range from 9 to 52 volts. The microphone shall be the AKG Acoustics Model C 426 B. Graphical Data AKG is constantly improving and modifying its products, therefore, specifications are subject to change without notice. Cardioid Omnidirectional Figure-eight Limited Warranty Valid only in the United States. AKG Acoustics warrants AKG products against defects in material or workmanship for a period of two years from the date of original purchase for use, and agrees to repair or, at our option, replace any defective unit without charge for either parts or labor.
