Description The AKG Model C 414 B/ULS is certainly the most ubiquitous studio condenser microphone in the United States, and very likely in the rest of the world as well. It is designed around dual back-to-back large 1 in. (25 mm) gold sputtered diaphragms for multiple pickup patterns. The microphone's pickup patterns are easily switchable among omnidirectional, cardioid, hypercardioid, and figure-eight. Additional flexibility in the studio operating environment allows a bass cut of 12 db/octave below 150 or 75 Hz and pre-preamp attenuation of either 10 or 20 db. The self noise of the microphone is a low 14 db (A weighted). On-axis sensitivity for all patterns is 12.5 mv/pa, and for unpadded operation maximum program level is 140 db for 0.5% total harmonic distortion. The C 414 B/ULS is one of the most accurate multi-pattern microphones available to the engineer. The far-field on-axis response for all four switchable patterns is remarkably flat, varying no more than +/-2 db over the range from 20 to 20 khz.

4015A, 4015A Wide Cardioid Microphone 4015A, 4015A Wide Cardioid Microphone Low profile wide pickup area Natural reproduction Directional ambience pickup Exceptional for vocal Expand your horizon with a wider pattern If you are already a DPA 4011 devotee, you will discover an exciting alternative in our wide cardioid microphones. The phantom powered DPA 4015A wide cardioid differs in its polar pattern and is the perfect fill-in between an omni and a more directional microphone. Sometimes a conventional cardioid pattern just isn t quite open enough, such as when recording instruments with complex radiation patterns. In those instances, the generous polar pattern of our Compact Wide Cardioids allows you to pick up a broader sound field and more accurately capture the full breadth of a stirring performance. Limitless applications The ST4015A stereo pair is supplied in a specially designed PeliTM Case, the stereo matching is free of charge. The SU4015A Surround Kit is supplied in a specially designed PeliTM Case, the surround matching is free of charge. For more information please visit: www.dpamicrophones.com Recording orchestras or other ensembles sometimes requires a compromise between blending in the room reverberation and a more precise localization. The wide cardioid (also known as hemispheric) design covers a greater sound angle and is an excellent choice for grand piano, guitar, marimba, and percussion, or as a spot mic for groups in a symphony orchestra. Likewise, it is an excellent speech, dubbing, or vocal mic as its enhanced richness on the bass end nicely compliments many voices. Completely linear, even off-axis The off-axis characteristics of the 4015A are totally linear, a unique quality when it comes to authentic sound reproduction. Any leakage that occurs from off-axis sound sources is still a faithful reproduction of these sounds, just softly attenuated. Specialists in extreme sound levels DPA s wide cardioid microphones are capable of handling extremely high sound pressure levels before clipping occurs. The 4015A even includes a 20 db pad switch in the center of the XLR connector to prevent overloading of the mic amp. Also available as matched stereo pair and surround kit Page 1 of 3

Brixen presents an overview of the 5100's features and functionality Plug-and-play solution Pressure Microphone) technology, which mounts interference tubes on the L/C/R omni capsules, and the use of acoustic baffles that further preserve the accuracy of levels between the discreet analog output channels. The 5100 s three front microphones are time coincident to eliminate comb filtering and ensure paramount frequency consistency when downmixing to stereo or mono. In contrast, the rear microphones, which feature standard omnidirectional patterns, are optimally spaced from both each other and the front array to simulate the most natural time arrival differences. The LFE (.1) channel is comprised from a L/R sum, which is then attenuated 10 db in comparison with the signal from the main channels, in accordance with the 5.1 format. The end result of DPA s innovative design approach is a surround atmosphere that is rich, smooth and fully enveloping, great in its coherence, channel separation and localization accuracy. The 5.1 output of the 5100 runs through a multi-pin Lemo connector carrying all six channels electronically balanced, while an enclosed five-meter (16 ft), six-pair Mogami cable breaks out to six Neutrik XLR-M connectors. Accessories included: Cable, thread adapter and outdoor cover. Lightweight and portable Accessories available: stands, cables and windjammer. Rich, smooth and fully enveloping sound Discrete 5.1 analog output no processing needed The DPA 5100 is an exciting new mobile surround microphone whose compact size and ease of use come at no sacrifice to its stunning sound quality.

"We struggled to find a fault. This is undeniably a great microphone ~ Audio Media magazine UMT70S FET Large diaphragm, transformerless multi-pattern studio microphone Multi-pattern large diaphragm Original M7 capsule Ultra-low noise circuit Excellent dynamics & response UTM70S Information: > Specifications > Freq response & polar patterns > Frequently asked questions The Gefell UMT70S is a multi-pattern FET microphone that features the legendary M7 dual-membrane, gold evaporated capsule with a new, stateof-the-art low-noise capsule amplifier for exceptional transient response, wide bandwidth and a natural uncolored sound. The ultra-slim design benefits the UMT70S with less acoustic field disruption around the microphone and greater placement ease when lose mic ing instruments. The UMT70S is ideal for recording, broadcast, voice-over and live sound reinforcement. Multi-pattern UMT70S - Order # G280-1130 Cardioid only: MT71S - Order # G280-1126 Development Early on, Gefell combined metal-film diaphragms with FET pre-amps as a means to reduce microphone self-noise, expand dynamic handling, and take advantage of the convenience of 48V phantom powering. Gefell first appeared in America in 1992 after Germany s Reunification with the launch of the original M70 Perestroika microphone. This Eastern-Block secret was quickly heralded as an incredible bargain with literally thousands being sold around the world. Almost overnight, the UMT70 became an industry favorite for voice and instruments, and was immediately honored with a prestigeous 1992 Tec Award nomination. With the shift to 24bit/96kHz recording a new microphone was developed that could properly address the demands for lower noise, wider bandwidth and the need for greater sound pressure handling. The Gefell UMT70S is the latest version of this classic featuring the same highly acclaimed M7 large diaphragm with an improved preamplifier section.
Design Features The Gefell UMT70S features a stylized slim-body design with a flared head that houses the capsule and the super-cool pattern selector switch. This diminutive design reduces sound pressure build-up and subsequent vortex around the mic while making placement easy when close mic ing instruments. Inside, mounted on Gefell s unique triangulated pedestal is the legendary M7 capsule. The Gefell M7 is a pressure gradient transducer, renown for its warm and natural tone. It features a dual 1-inch (25mm), 24-karat gold evaporated membrane design with a PVC substrate. The M7 is considered by many to be the finest capsule ever made. The triangulated capsule pedestal deflects unwanted body reflections away from the microphone, reducing phase cancellation and comb-filtering. This of course benefits with greater source detail, improved upper-harmonic reach, and a more articulated rendering. With the advent of digital recording and digital broadcast, the demand for improved performance set the path to upgrade the UMT70S circuitry. The introduction of a new transformerless preamplifier with a symmetrical output stage benefits the microphone with a significant reduction in selfnoise, a broader and more uniform frequency response, and an explosive transient response that is capable of 149dB. The UMT70S features a precision-machined pattern selector switch below the capsule grill that is rotated to select between the omnidirectional, cardioid and figure-8 polar curves. Mid-way down the body stem are controls for the 10dB pre-attenuation pad and the smooth low-frequency roll off (-10dB@90Hz). Using the UMT70S As a large diaphragm microphone, the Gefell UMT70S produces a warm full-bodied sound that is both natural and uncolored. With exceptionally good on and off-axis response, the side-address UMT70S is equally at home in the studio or in a live recording environment. In the omnidirectional mode, a ruler-flat bottom end is combined with a slight 2dB rise in the 10kHz region making the UMT70S ideal for ambient recording and orchestral works. In the cardioid and figure 8 modes, the UMT70S is voiced with a smooth presence rise in the 7kHz region. This response, coupled with a slight low-frequency roll-off gives the UMT70S its legendary "shimmer" making it a great choice for voice-over, solo vocal and instrument. When close mic ing, activating the low-frequency roll off gently curbs unwanted rumble and tightens bass by controlling proximity build-up further adding to the UMT70S flexibility. To reduce noise caused from vibration, the EA21 elastic suspension is recommended. The clamp-style microphone retainer inside the elastically suspended basket provides a safeguard against damage allowing the mic to be used at all angles. Hook-up is simple with a standard 3-pin XLR cable and 48V phantom powering.
Interpretation By combining the famous M7 capsule with an improved low-noise power supply, Gefell has once again set a new level of performance in a full bandwidth studio microphone. The combination of three well behaved patterns, greater sensitivity, exceptional signal-to-noise, above average transient response and a wide, noise free bandwidth housed in a compact body make the Gefell UMT70S a true desert island microphone. The accurate and colorless sound of the UMT70S opens the door to greater creativity and freedom, making it a superb choice for recording and particularly well suited for instrumental and vocal soloists in radio and television broadcast. Comes in it's own beautifully hand-crafted wood box. << Back Top UMT70S Specifications Next >>

he TLM 103 is the ideal large diaphragm microphone for all professional and semi-professional applications requiring the utmost in sound quality on a limited budget. By utilizing the tried and true transformerless circuit found in numerous Neumann microphones, the TLM 103 features yet unattained low self-noise and the highest sound pressure level transmission. The capsule, derived from that used in the U 87, has a cardioid pattern, is acoustically wellbalanced and provides extraordinary attenuation of signals from the rear. The TLM 103 is available in satin nickel and matte black. Delivery includes an SG 1 metal swivel mount and a wooden jeweler s box. Applications Due to the universal cardioid pattern, straightforward handling, extremely low self-noise level, and finally, the price, the TLM 103 is predestined for all demanding applications from home recording to professional broadcasting and commercial recording studios. Polar pattern The TLM 103 is equipped with a large diaphragm capsule with cardioid pattern. By focusing on this pattern used in most recording situations the attenuation of unwanted rear sound has been optimized. Off-axis sounds are rendered naturally while isolation is increased. This also leads to a high feedback suppression when the microphone is used in live situations or where loudspeaker playback is a factor. Acoustic features The TLM 103 is addressed from the front, marked with the red Neumann logo on the microphone body. The K 103 large diaphragm capsule is based on the K 87, well known from the U 67 / U 87 microphones.

TLM 103 Large Diaphragm Microphone The capsule has a flat frequency response up to about 5 khz, and above that, a wide flat 4 db presence boost. The large wire mesh headgrille protects the capsule from plosive sounds and effectively prevents pop noises. These characteristics are achieved without resorting to corrective resonance effects. Therefore, the microphone maintains an excellent impulse response and reproduces the finest details of music and speech without coloration. Electrical features With just 7 db-a / 17.5 db CCIR the self-noise level of the TLM 103 is so reduced that even the smallest signals are reproduced basically noisefree. As it is capable of handling sound pressure levels up to 138 db without distortion, the TLM 103 provides a dynamic range of 131 db, according to DIN/IEC 651. The letters TLM stand for transformerless microphone. With TLM technology the usual output transformer is replaced by an electronic circuit. As with traditional transformers, it ensures good common mode rejection, and prevents RF interference that may influence the balanced audio signal. Operational safety The entire internal construction is elastically mounted to attenuate any structure borne noise that could interfere with the TLM 103 s operation. Furthermore the capsule is set on an elastic mount. The frequency range reaches below 20 Hz and ths even very low bass signals are reproduced without coloration. Due to this low frequency extension, the TLM 103 is more sensitive to structure borne interference and wind noise. For such cases, the elastic suspension EA 1 and the windscreen WS 87 are available as accessories. For close vocal use, the PS 10 or PS 20 pop screens are recommended.

Neumann U89i The U 89 is a studio microphone for universal applications. The headgrille protects a dual-diaphragm capsule. A rotary switch below the headgrille selects from five different polar patterns. Therefore the microphone can be adapted easily to large sound sources, and those that are spread wide apart, or to sound sources to be recorded at a greater distance. The amplifier accepts sound pressure levels up to 134 db without distortion. This figure can be increased to 140 db. An additional rotary switch activates a filter that changes the low frequency response either below 80 Hz or 160 Hz frequency. Applications The U 89 i is similar in appearance to the U 87. It is of smaller size, and lighter weight. It features five instead of three directional characteristics and a higher maximum sound pressure level which make this microphone easier adaptable to different applications. Polar patterns In addition to the usual directional polar patterns: omnidirectional, cardioid, and figure-8, we have added a hypercardioid and wide-angle cardioid characteristic. When compared to the standard cardioid pattern, the hypercardioid characteristic suppresses sound from the side more efficiently. The wide-angle polar pattern is especially useful to record large sound sources. Acoustic features The microphone is addressed from the front, marked with the Neumann logo. The large diaphragm capsule has a very smooth frequency response for all polar patterns over a wide acceptance angle. The frequency response curves are flat up to 10 khz within a pickup angle of ± 100. As a result the U 89 i has a very even diffuse-field response for all polar patterns. This is important in a reverberant environment when more reflections arrive at the microphone capsule. The acoustic information is not affected in its tonal quality when recorded by the microphone. This characteristic is achieved without resorting to corrective resonance effects. The capsule it is elastically mounted to avoid any structure borne noise that could interfere with its operation. Filter and attenuation The amplifier handles sound pressure levels up to 134 db without distortion. With a self noise level of 17 db (A-weighted) the total dynamic range is 117 db. Maximum sound pressure level is 140 db when the - 6 db rotary switch is in the ON position. A low frequency roll-off at 80 Hz or 160 Hz can be activated with another rotary switch below the headgrille. This filter suppresses low frequency interference, yet maintains an even frequency response for close-up sound sources, for example, when proximity effect could adversely affect the program material. A steep high-pass filter in the LIN position prevents the output transformer of the microphone from being overloaded due to undesired subsonic frequencies. Operational safety All exposed surfaces of the microphone capsule, including the diaphragms, are at ground potential. This technology makes them highly immune to electrical and atmospheric interference and contamination through microscopic dust particles.
