57 DYN

What can you say about the Shure SM57 It is a tool found in the workbench of every sound engineer, both for live and studio applications. There's simply no question: it's a "must-have" mic.

The SM57 is a cardiod (unidirectional) dynamic microphone with a contoured frequency response of 40 to 15,000 Hz, perfect for clean reproduction of vocals and instruments. But the SM57 is most renowned in the music industry as the standard microphone of choice for snare drums and guitar amplifiers. Go to any stage or studio and you're likely to find SM57s pointing at the amps and snare.

By the way, the '57 has been proudly standing on the podium of the US President for over 30 years, so you can add patriotism to its outstanding attributes! This mic is also known to take a beating and come back for more, so tell your roadie Rocco to have a ball! Its outstanding performance, legendary reliability, and diversity of application make this "workhorse" the choice of performers, producers, and sound engineers the world over.

87A COND The Shure Beta 87A is a premium quality supercardioid hand-held electret condenser vocal microphone with exceptionally smooth frequency response and high sound pressure level capability. Used for professional sound reinforcement, broadcasting, and studio recording applications, the Beta 87A combines superb performance with the ruggedness needed for touring and field production.

The Beta 87A features a controlled low-frequency roll-off that compensates for proximity effect and prevents the “boomy” sound often associated with close pick-up. The characteristic Shure presence rise brightens the upper midrange. The tight supercardioid pattern, with null points at approximately 125 degrees, provides maximum isolation from other vocalists or instruments while offering minimal off-axis coloration. The Beta 87A operates on phantom power.

U87 COND Over 50,000 Neumann U87 users can't be wrong, this microphone is the professional standard and sets the mark by which all others are measured. The U 87 will celebrate its 40th birthday in 2007 and is still going strong.

The U 87 is probably the best-known and most widely used Neumann studio microphone. It is equipped with a large dual-diaphragm capsule with 3 directional patterns: omnidirectional, cardioid, and figure-8. These are selectable with a switch below the headgrille. A 10 dB attenuation switch, located on the rear, enables the microphone to handle sound pressure levels up to 127 dB without distortion. Furthermore, the low frequency response can be reduced to compensate for proximity effect.

E609 DYN

Sennheiser e609 Silver

The e609 Silver is based on the legendary MD 409 microphone. Able to withstand high SPLs without distorting, the e609 Silver's flat-profile capsule allows extremely close miking of guitar cabinets and precise drum miking, particularly toms. The e609 Silver's super-cardioid design improves isolation while its increased output and wider frequency response improves performance. Its sound inlet basket, made of refined steel, is distinguished by a unique silver address side.

Electro-Voice Model RE16 DYN

Description The Electro-Voice Model RE16 is a Variable-D® dynamic supercardioid micro­phone designed for the most exacting professional use. It is like the RE15, except that it uses a unique blast filter. The blast filter, an integral part of the RE16, permits hand-held and outdoor use without “P-popping” or excessive wind noise.

Utilizing the Variable-D® design, the RE16 features a directional characteristic independent of frequency. The result is a microphone that generates little off-axis coloration while providing the greatest rejection of unwanted sounds. A super-cardioid, the RE16 provides its greatest rejection at 150 degrees off axis. Typical cardioids provide greatest rejection in the horizontal plane when the microphone is tilted In its most natural position –30 degrees from horizontal as on a boom or floor stand.

An easily operated “bass-tilt” switch corrects spectrum balance for boom use and other longer reach situations. A “hum-buck” coil and screw-machined steel outer casing provide 25 dB of hum rejection. Hum pickup level is –125 dBm (re: .001 gauss field).

Using the mechanical nesting concept of design, by means of which the internal transducer parts are nested one within another, the RE16 transducer is a nearly solid mechanical structure that is highly resistant to damage from mechanical shock. The Memraflex grille screen resists deformation. The exclusive non-metallic Electro-Voice Acoustalloy diaphragm is virtually unaffected by extremes of atmospheric conditions. A carefully designed steel outer case provides additional mechanical protection. Finish is non-reflecting fawn beige micomatte.

R121 Cond
Royer Labs R-121 Ribbon Microphone

Like many of the best loved classic ribbon mics, the R-121 has a figure-8 pattern, sensitivity in the dynamic mic range, and a warm, realistic tone and flat frequency response. But that’s where the similarities end. By using advanced materials and a blend of cutting edge and old-school hand-build construction techniques, the R-121 is a far more versatile and user-friendly ribbon mic that can stand up to the most demanding tasks, including live stage use. It’s built solid enough for us to give it a lifetime warranty. The R-121 redefined ribbon microphones so thoroughly that Recording Magazine wrote "…the Royer R-121 is destined to become one of the classic microphones of the 21st century".

Acoustic Operating Principle: Electrodynamic pressure gradient Polar Pattern: Figure-8 Generating Element: 2.5-micron aluminum ribbon Magnets: Rare Earth Neodymium Frequency Response: 30 -15,000 Hz +/- 3dB Sensitivity: -50 dBv Re. 1v/pa Output Impedance: 300 Ohms @ 1K (nominal) Rated Load Impedance: >1500 Ohms @ 300 Ohms Maximum SPL: >135dB @ 20 Hz

67 COND Neumann U67

The microphone capsule of the U 67 microphone is a pressure-gradient device. It is composed of two identical cardioid systems arranged back to back. By switching of the polarizing voltage these two cardioid patterns can also be combined as to produce the three directional characteristics cardioid, omni-directional, and figure-8. Selection of these patterns is accomplished by a switch located at the front of the microphone directly beneath the wire cage. The symbol of the characteristic selected appears in a window directly above the switch. Two additional switches are located at the rear of the microphone. One switch provides for a sensitivity reduction of appr. 10 dB ahead of the amplifier section permitting transmission of the highest sound pressure levels without danger of overloading the amplifier. The second switch produces a roll-off at the low frequency end beginning at 200 cps. This permits compensation of the normally occurring low frequency rise when a pressure - gradient microphone is addressed at close range. This position further serves to suppress low frequency mechanical interference. These two switches like wise have windows in which their position is indicated. When the sensitivity reduction is effective, the window shows "-10 dB", and when the low frequencies are attenuated, the window shows a horizontal line with its left end bent downward. (These symbols are described as viewed when the microphone is on a stand with its connector end facing the floor.) A special circuit within the amplifier distinctly attenuated all frequencies below 30 cps, while those above 40 cps are reproduced linearly. The microphone amplifier's response may be extended to below 20 cps flat by opening the jumper "S-2" in the amplifier itself.
