GENERAL

The Model SM7A is a dynamic microphone with a very smooth, flat, wide-range frequency response. It is meticulously designed for the most exacting music and speech requirements in profes- sional audio applications. The cartridge has been updated from the original SM7 with improved shielding against electromagnetic hum generated by computer monitors, neon lights, and other electrical devices.

Features

•Flat, wide-range frequency response for exceptionally clean and natural reproduction of both music and speech

•Bass rolloff and mid-range emphasis (presence boost) controls with graphic display of response setting (see figure 3)

•Improved rejection of electromagnetic hum, optimized for shielding against broadband interference emitted by com- puter monitors

•Internal ªair suspensionº shock isolation virtually eliminates mechanical noise transmission

•Highly effective pop filter eliminates need for any add-on protection against explosive breath sounds, even for close-up vocals or narration

•Yoke mounting with captive stand nut for easy mounting and dismounting provides precise control of microphone position

•Cardioid polar pattern, uniform with frequency and symmet- rical about axis, to provide maximum rejection and mini- mum coloration of off-axis sound

•Rugged construction and excellent cartridge protection for outstanding reliability

APPLICATIONS

MOUNTING INSTRUCTIONS

The SM7A can be mounted on a microphone stand or hung from a boom. It is shipped in the boom mounting configuration (see figure 1). To set up the SM7A in the microphone stand mounting configuration (see figure 2), proceed as follows:

1.Remove tightening nuts on the sides (see figure 7).

2.Remove the fitted washers, the lock washers, the outer brass washers, and the brass sleeves.

3.Slide the bracket off the microphone. Be careful not to lose the washers still on the microphone.

4.Invert and rotate the bracket. Slide it back onto the bolts over the brass and plastic washers still on the microphone. The bracket should fit so the XLR connector faces the rear of the microphone, and the Shure logo on the back of the microphone is right-side up.

5.Replace the brass sleeves. Be sure they are seated proper- ly within the inner washers.

6.Replace the outer brass washers, the lock washers and the fitted washers.

7.Replace the tightening nuts and tighten the microphone at the desired angle.

NOTE: If the tightening nuts do not hold the microphone in position, one or both of the brass sleeves may not be properly seated within all the washers.

SM7A specifications

The Shure SM7A is a dynamic cardioid microphone that has gained a reputation as a versatile and high-performance tool, particularly favored in the realms of broadcasting, recording, and live sound. Known for its rich sound quality, the SM7A is an evolution of the legendary SM7B, carrying forward the design principles that have made its predecessor a staple in studios around the world.

One of the main features of the SM7A is its cardioid polar pattern. This design allows the microphone to capture sound from the front while minimizing background noise and ambient sounds from the sides and rear. This characteristic makes it ideal for vocal applications, where clarity and presence are vital. The SM7A excels in recording vocals, instruments, and even amplifiers, providing a detailed and natural sound reproduction.

Another notable feature is the built-in air suspension system. This technology helps to isolate the microphone from mechanical noise and vibrations that could affect the audio quality. Additionally, the SM7A includes a frequency response that is tailored for voice, with a bump in the mid-range frequencies to enhance vocal clarity. It also features a presence boost that can be engaged to add brightness and attack when needed.

The SM7A is also designed with durability in mind. Its robust construction ensures that it can withstand the rigors of studio use as well as being transported for live performances. The microphone is equipped with a detachable windscreen, which helps reduce plosive sounds caused by explosive consonants, making it suitable for close-miking applications.

Furthermore, the SM7A incorporates a switchable low-cut filter and a mid-range boost, allowing users to customize the frequency response according to their requirements. This flexibility makes it a powerful tool in the studio, able to adapt to various vocal types and recording situations.

In conclusion, the Shure SM7A stands out for its exceptional sound quality, versatility, and durability. Whether used for vocals, instruments, or broadcast applications, this microphone delivers a professional-grade audio experience that has made it a top choice among sound engineers and musicians alike. Its combination of advanced technologies and user-friendly features ensures that it remains a relevant and prized addition to any audio setup.
