ARCHITECTS' SPECIFICATIONS

The microphone shall be a moving coil (dynamic) type with a frequency response of 50 to 20,000 Hz. The unit shall have a cardioid polar characteristic. The cancellation at the sides shall be approximately 6 dB and the cancellation at the rear shall be 15 to 20 dB. The microphone shall be low impedance with a rated impedance of 150 ohms for connection to microphone inputs rated at 19 to 300 ohms. The microphone output shall be ±57.0 dB where 0 dB = 1 milliwatt per Pascal.

The microphone shall have two switches for controlling the frequency response. The first switch is a Bass Rolloff selector

switch. One position of this switch provides a flat low frequency response and the second position provides a gradual low frequency rolloff. The second switch is the Mid-Range Emphasis (presence boost) switch. One position of this switch provides a flat mid-range frequency response and the second position raises the level of the mid-range frequency response. The microphone shall be equipped with an integral swivel assembly suitable for mounting on a stand with a 5/8 in-27 thread.

The overall dimensions shall be 189.7 mm (7.469 in.) in length, 148 mm (5.812 in.) in height, and 96 mm (3.775 in.) in width. The weight of the microphone shall be 765.4 g (1 lb., 11 oz.)

The microphone shall be the Shure Model SM7A or equivalent.

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.
