What We Think

All capsules are available in matched pairs with official Schoeps documentation. For matched pairs multiply the cost of the microphone exactly by two and then add $40ollars for the matching fee! The amplifier bodies are available in sequentially serial numbered pairs at no additional charge. Any Schoeps product not found on our webpage can be purchased through Sound Pure. Please call and talk to one of our staff members to inquire about the price and availability!

Manufacturer's Description from Schoeps

Although the CMC 5 Ug has a more modern successor (the CMC 6 Ug), some people place a special value on its discrete circuitry, or require an exact match for an existing microphone amplifier of this same type. 

The CMC 5 Ug is designed exclusively for 48-Volt phantom powering.

The capsules of condenser microphones – the only type which SCHOEPS manufactures – cannot be connected directly to microphone cables or inputs; a microphone amplifier is required in between. Thus a complete microphone of the Colette series comprises any of the twenty-one available types of capsules combined with an amplifier.

The microphone amplifier provides the electrostatic charge which the capsule requires in order to produce a signal. Since only a miniscule amount of current is contained in this signal, amplification of the current is required. To avoid interference to the signal on the way from the microphone to the input of the mixer or preamp, the signal is conveyed at low impedance and in balanced form. CMC 5 Ug amplifiers offer a balanced, transformerless, direct-coupled Class A output stage with low impedance, low distortion, and high freedom from interference

Features:

  • Predecessor of the CMC 6 Ug
  • Made for P48 phantom powering

For installations in which 48-Volt powering will always be provided and in which RFI is not an issue, the model CMC 5 Ug is available.

Variant Amplifier Versions

Special versions of the CMC 5 Ug are available with different gain (amplification factor) or extended low-frequency range. Either type of amplifier can be specially ordered, or retrofitted at the factory, to have a different low-frequency limit from the standard version (see, for example, the ”linear” version listed below).

CMC 5 Ug Linear

The CMC 5 Ug microphone amplifier normally has a gradual rolloff in response below 30 Hz to guard against infrasonic disturbances from various sources such as air movement and vibration. However, when using pressure (omnidirectional) transducers, particularly with digital recording, it can be desirable to pick up frequencies below 20 Hz without attenuation. The special technology of the CMC 5 Ug linear microphone amplifiers makes this possible; on request we can deliver microphone amplifiers with response that is flat to as low as 3 Hz.

Caution must be advised with respect to infrasonics, however. Since pressure transducers can pick up very low frequencies, ventilation systems in large spaces (churches, concert halls) or traffic rumble can create a problem. With pressure gradient transducers the risk is even greater. They are far less sensitive to very low frequency sound, but respond much more strongly to low-frequency mechanical stimuli such as air currents and solid-borne noise. Such signals may be below the audible range of frequencies, but they can overload electronic circuitry and produce severe distortion, particularly in transformer-coupled circuitry.

CMC 5 Ug +5 dB

The sensitivity of a microphone using this type of amplifier is 5 dB higher than with the standard version, but the equivalent noise level and maximum output voltage are not materially affected. Thus the highest sound pressure level which the microphone can accept without distortion is 5 dB lower than in the standard version, while the signal-to-noise ratio is essentially the same with either gain setting.

This version might be chosen in order to raise the microphone's signals above the noise level of the equipment to which it will be connected, and / or for working with sounds that occur mainly at low levels

About Manufacturer

The focus on high quality, reliability and neutral accurate sound has been the production philosophy of Schoeps Microphones since 1948. The simple elegance and clever engineering of their products boast a true passion for the art of microphone making and a tireless attention to detail. The Colette System is the largest modular mic system available offering twenty different capsules and various active accessories. The newest addition to the acclaimed Colette System is the CMC 6 xt which offers extended frequency response beyond 40 kHz. The CCM Series mics are the smallest phantom powered non-electret microphones in the world. Other notables from Schoeps include the M222 Tube microphone, the VMS 5U portable two channel mic preamp and M/S matrix, three extremely unique stereo mics, the KFM-360 Surround microphone and the Polarflex Microphone System that allows the user to emulate the characteristics of any microphone. Schoeps is unquestionably among the most innovative microphone manufacturers in the world, leading the way in many developments. Central to its design philosophy over the years is the company's insistence on absolute sound neutrality of the microphones. It is really no wonder that Schoeps has so many supporters, not only in the area of classical music recording and reinforcement, but also in film and television. No doubt part of its success is due to the fact that, in a space of only 1500 square meters, a total of 35 employees develop, manufacture and distribute the whole range of Schoeps products. Staff turnover is very small, which says much about the family atmosphere in the company. Many an employee has celebrated his or her 25th anniversary with Schoeps. Continuity is and will remain very important at Schoeps. Despite many outside offers, Ulrich Schoeps intends to continue the life's work of his father.
