Selecting a Microphone
While professional users typically understand their specific needs, AKG assists in selecting the most appropriate microphone type. Professionals working in diverse environments like motion-picture sets, recording studios, auditoriums, and broadcast facilities are familiar with the technical specifications such as response curves and polar patterns.
AKG encourages location testing of specific models, acknowledging that the environment can influence ideal results. AKG dealers are available to assist in confirming the proper microphone choice.
Key considerations for professionals are product quality and dependability. AKG quality ensures consistency in performance characteristics across identical microphone models. Dependability is achieved through the use of the finest materials and meticulous manufacturing, resulting in rugged units that maintain high acoustic quality.
AKG microphones are used globally in thousands of recordings and broadcasts, from classical to rock music, contributing to fine sound reproduction. For discerning users, acoustic quality, dependability, and serviceability are paramount criteria.
Impedance and Output Connections
Most AKG E- and EB- suffix microphones and preamp-capsule combinations are low-impedance, balanced-output units fitted with a standard 3-pin XLR-type connector. The nominal output impedance is 200 ohms, compatible with all low-impedance inputs (25-1000 ohms).
XLR Connector Pin Connections:
Pin 1: Shield
Pin 2: Audio, in-phase ("hot")
Pin 3: Audio, low
For phantom-powered condenser models, pins 2 and 3 jointly carry the positive powering voltage, while pin 1 carries the negative side.
Models without a suffix (e.g., C-24, D-110) also have a 200-ohm output impedance but are supplied with audio-output cables having stripped and tinned leads for custom installation. Color coding for these cables is as follows:
C-24: Red = in-phase, fixed capsule; Black = low, fixed capsule; White = in-phase, rotatable capsule; Green = low, rotatable capsule.
D-110: Red = in-phase; White = low.
For high-impedance applications, AKG offers MCH 20T or MCH-20TS transformer cables. These are designed to maintain the advantages of low-impedance balanced-output microphones over the entire cable run to high-impedance inputs, preventing hum and high-frequency loss.
MCH-Series Heavy-Duty Microphone Cables
Historically, microphone cables presented a compromise between strength, flexibility, size, weight, and cost, often leading to wear and tear, resulting in dead or intermittent microphones and excessive RF or hum pickup.
AKG researched cable design problems and field information to develop cables that meet the demands of hard everyday use. The "MCH" series features a structural design similar to lightweight TV camera cables, offering strength, durability, flexibility, small diameter, and vastly improved reliability. These cables are available in four optional colors: red, green, blue, and black, allowing for easy microphone and input coding.
Available cable assemblies include:
MCH-20: Low-impedance, no switch (female XLR to male XLR)
MCH-20F: Low-impedance, no switch (female XLR to stripped/tinned ends)
MCH-20P: Low-impedance, no switch (female XLR to phone plug)
MCH-20S: Low-impedance, with switch (female XLR to male XLR)
MCH-20T: High-impedance, no switch (female XLR to transformer with phone plug)
MCH-20TS: High-impedance, with switch (female XLR to transformer with phone plug)
MCH-50: Low-impedance, 50' cable (female XLR to male XLR)
Most MCH cable assemblies are approximately 20' long, except for the MCH-50.

A complete line of "KM" microphone stands and accessories is available from AKG. Details and descriptive literature can be obtained from AKG dealers.
C-24 Stereo Studio-Condenser Microphone
The C-24 is designed for M-S and X-Y "intensity" stereophony techniques, popular in major recording companies and broadcast networks. Originally intended for true "concert-hall-sound" reproduction of orchestras and ensembles, these techniques are now applied in studio rock sessions.
Essentially two matched large diaphragm microphones in one housing, the C-24 is an updated "twin C-12," known for its professional use. It's a time-tested vacuum-tube unit, popular as both a location and studio microphone.
The C-24 features a co-planar (and rotatable) twin-capsule arrangement, inherently free of phase error. Its remote power supply allows dual-channel pattern selection. Each capsule can be individually aimed, with up to 180 degrees of angular offset. Each capsule's directional characteristic can be independently and remotely varied across nine patterns, from omnidirectional to cardioid, hypercardioid, and figure-eight.
The remote pattern selector can be installed at the console, offering fingertip control over stereo image width and spaciousness (ratio of direct-to-reverberant sound pickup). For more information on intensity stereophony, AKG offers a booklet titled "M-S Stereo Recording Techniques."
The C-24 contains two separate 1" dual-diaphragm capsules, designed for equal phase and amplitude response in all polar pattern combinations. Each capsule is followed by an impedance converter/preamplifier for a low-impedance, balanced output. A 66' multiconductor cable connects the microphone to its power supply/dual-pattern-selector unit. Each C-24 is supplied with individual proof-of-performance frequency-response curves for each capsule in its three basic directional modes: omni, cardioid, figure-eight.

The Patented AKG Two-Way System
The AKG Two-Way microphone system divides the total response range between a high-frequency and a low-frequency transducer, each optimized for its specific range, similar to a two-way loudspeaker system. The two systems are connected by a crossover network with the crossover frequency at 500 Hz.
Internal Arrangement:
The high-frequency system is mounted on the protective cap of the low-frequency system.
The low-frequency system is connected to a mass tube with apertures at the rear. For maximum reduction of wind sensitivity, the aperture does not connect directly to open air but leads to a chamber coupled to the sound field via slotted openings covered with damping material.
The high-frequency system is shock-mounted to reduce handling sensitivity and has a compensating winding to eliminate stray magnetic fields.
The crossover network is housed in the tower portion of the microphone.
This unique arrangement achieves several performance characteristics previously unobtainable for cardioid dynamic microphones:
Flat frequency response over the entire audible range: Both low and high-frequency systems are optimally adjusted, with the 500 Hz crossover point being unnoticeable.
Linear off-axis response: Sound reaching the microphone 90° off-axis is reproduced naturally, without audible frequency-discriminating characteristics common to standard cardioid dynamic microphones.
Uniform front-to-back discrimination: The system maintains at least 20 dB front-to-back discrimination over its entire frequency range, including low and upper mid-range areas.
Absence of proximity effect: A complete absence of the rise in low-frequency response when used in close-up applications, compared to other directional microphones.
These features offer practical advantages:
The flat frequency response allows for natural and faithful sound pickup and facilitates feedback control at virtually any frequency in public-address installations.
The linear 90° off-axis response is important in recording when multiple microphones are used, as sound leakage from other instruments is reproduced faithfully without frequency discrimination. This also applies to public-address systems where speakers move off-axis.
Uniform front-to-back discrimination is crucial for public-address systems, virtually eliminating feedback and allowing greater freedom in microphone and speaker placement. This design has been found to allow approximately 6 dB gain increase in many sound systems and offers better-than-average separation in recording.
D-202E Two-Way Cardioid Dynamic Microphone
The D-202E was the first two-way cardioid dynamic microphone and is now a classic in recording, broadcast studios, film sound stages, sound-reinforcement installations, and remote assignments worldwide.
The versatile D-202E exhibits the special characteristics unique to AKG's patented two-way microphones: exceptionally smooth, wide-range frequency response, unusually uniform directivity over most of its frequency range, and virtually no proximity effect.
It is recommended for applications where faithful music and speech reproduction (on and off axis) and effective, uniform rejection of background noise and feedback are paramount. An added feature is the three-position bass-rolloff switch (0, 7 dB, or 20 dB attenuation at 50 Hz) for control over low-frequency content and noise.
The microphone's distinctively shaped windscreen/pop filter is made of sintered bronze (an AKG exclusive) and protects the two-way transducer system against particles, dust, and spittle.

D-222E Two-Way Cardioid Dynamic Microphone
The D-222E is an improved, smaller version of the classic D-202E, incorporating further refinements of the patented AKG two-way design principle. It exhibits exceptionally smooth, wide-range frequency response, nearly ideal directionality, and virtually no proximity effect.
Equipped with switchable bass roll-off (0, 6, or 12 dB attenuation at 50 Hz) and internal shock suspension, the D-222E is suitable for most acoustic environments. It is highly recommended for applications requiring faithful music and speech reproduction with natural, uniform, and uncolored tonal quality, regardless of performer position or distance, while providing effective, uniform rejection of background noise and feedback.
Internally, dual transducers and the crossover network are elastically suspended within a field-replaceable module, providing isolation against handling noise, mechanical shocks, and vibrations. The microphone's windscreen/pop filter is made of sintered bronze.
Supplied complete with proof-of-performance frequency-response and 180° rejection curves, SA-12/1 Black stand adapter, and foam-lined vinyl case.
Specifications:
Transducer Type: Dynamic, two-way system
Directional Characteristics: Cardioid
Sensitivity: -55.5 dBm (EIA G, : -148 dBm)
Finish: High-impact black ABS-polymer; nickel-plated die-cast zinc; sintered bronze
Overall Dimensions: 8 1/8" long x 1 3/8" dia.
Net Weight: 9 oz.
C-450 Modular Condenser Microphone Additions
CK-4 Figure-Eight Capsule
This bidirectional capsule is invaluable for M-S or Blumlein stereo arrays, coverage of performers facing each other, and superior side rejection of noise or feedback. The CK-4 features virtually identical front and rear frequency response and sensitivity, plus exceptionally high front-to-side discrimination.
Its two closely matched transducer elements are oriented back-to-back. An integral wire-mesh windscreen with polyurethane-foam lining minimizes breath "pop" and wind noise. The capsule is finished in satin black chrome with a white dot indicating its "front" (in-phase axis of maximum sensitivity). Supplied with an individual proof-of-performance frequency-response curve and foam-lined vinyl case.
Specifications:
Transducer Type: Dual-diaphragm condenser
Directional Characteristics: Figure-eight
Sensitivity: -45 dBm (EIA G, : -138 dBm)
Finish: Black chrome-plated brass
Overall Dimensions: 3 1/8" long x 1 1/16" dia.
Net Weight: 4 oz.
CK-22 Omni-directional Capsule with Integral Pop Filter
This capsule features extraordinarily flat and extended on-axis response coupled with uniform non-directional pickup. Slightly longer than the original CK-2, the CK-22 contains an integral pop/blast filter for hand-held vocal applications like television, music, variety, and game shows, or interviews/news gathering. It is recommended for applications requiring emphasis on acoustic ambience, faithful reproduction of deep-bass fundamentals and high-treble overtones, non-discriminating coverage of multiple performers, or close-miking free of proximity effect.
See pages 7 through 12 for other components of the C-450 Modular Microphone System.
C-414EB/Remote Comb
The C-414EB polydirectional studio condenser microphone has been adapted for use with the S-42E1 Remote Pattern Selector, providing independent adjustment of the capsule's polar response over nine patterns (omni, cardioid, hypercardioid, figure-eight).
The S-42E1 controls one or two C-414EB/Remote microphones and is phantom powered (9-52 volts). The unit comprises one C-414EB/Remote microphone, MK-23120 cable, S-42E1 remote control, SA-18/3 clamp stand adapter, W-26 windscreen, and foam-lined carrying case.
