Schoeps CMC 621 Wide Cardioid Condenser Microphone Set

The Schoeps CMC 621 Microphone Set is a complete wide cardioid condenser microphone set including amplifier, capsule, popscreen, clamp and box.

CMC 6 Amplifier

The CMC 6 is designed for standard 48- and 12-Volt phantom powering. Its circuitry recognizes the supply voltage and adjusts itself automatically. Its performance characteristics remain essentially the same either way; mainly, the difference is that the current drawn at 12 Volts is greater than at 48 Volts. However, the 12-Volt mode consumes less power and might be preferred for battery-powered recording.

The microphone amplifier is responsible for providing the necessary electric charge to the capsule, without which it would be unable to generate a signal. Since the capsule's output signal is very weak (Hi-Z), it must be amplified. In order for the microphone's output to cleanly reach the next stage in the signal chain, it must undergo balancing and impedance matching before transmission. The CMC 6 incorporates a balanced, direct-coupled class-A amplifier, yielding a low output impedance, high RF shielding, and minimal distortion.

FEATURES:

• Flat frequency response
• Very low harmonic distortion and noise
• Works with 12V and 48V phantom power
• Balanced, low-impedance output
• High suppression of interference on the Microphone cable
• Excellent protection against high-frequency Radio interference with "RFI Shield"
• Frequency-independent impedance
• Signal transmission possible over very long cables
• Reliable operation even with weak phantom power
• Symmetrical, transformer- and capacitor-free output stage with a Cass A amplifier
• Above 20 kHz, the signal is attenuated for protection against interference in the ultrasonic range, e.g. through the ultrasonic autofocus of a film camera

MK 21 Capsule

The directivity of the wide cardioid lies between the omni and the cardioid. The idea behind their development is to combine the advantages of these two patterns. The low-frequency behavior of the Schoeps MK 21 is better than that of the cardioid, and proximity effect is less pronounced. The wide cardioid polar pattern is extremely consistent across the frequency range. Laterally-arriving direct sound and reflections are picked up without added coloration. The MK 21 is a very well-liked capsule. It is preferred when a slight directional effect and a warm, natural sound image are desired. Over the years it has become an integral part of the audio engineer's toolkit.

When used as a spot microphone, the distance from the sound source should be slightly smaller than when using a cardioid due to lower directivity index.

The low directivity of this capsule type prevents it from generating large enough level differences for X/Y use, though MS and near-coincident spacings are often successful.

FEATURES:

• Wide cardioid polar pattern
• Preferred uses: as a soloist microphone or main microphone
• Extremely consistent polar response leads to a very natural sound
• Combines the advantages of the omni (warm sound) and the cardioid (directivity)
• Popular as a main microphone pair e.g. at a spacing of 30 cm, angle ±45°

SCHOEPS COLETTE

The Colette series was introduced back in 1973 and has since been made up of mutually compatible modules that are constantly being updated and supplemented. No other microphone system has been on the market for such a long time. The Colette series invented the modularity in microphone technology and is considered more than ever before to be the best small-diaphragm microphone system.

Microphones from the modular Colette series are comprised of a microphone capsule screwed onto an amplification unit. Any capsule can be combined with any amplifier. Active accessories can be inserted between capsule and amplifier if desired. The RC active extension tube in particular graces many high-profile events with its stylish appearance. Due to its modular nature, the Colette system offers a large variety of options, for a wide range of use cases.
