However, because the 30° off-axis response is smooth, simple equalization can compensate for its decreased high frequencies if necessary. The curve below shows the SM89 response at 30° off-axis, with the equalization that can be used to restore the high- frequency response.

ACCESSORIES

The supplied windscreen is useful under most indoor-conditions where minimal wind noise due to boom motion, air conditioners, or heater fans is present. When structure-borne mechanical vibration must be cancelled, the optional Model A89SM Shock-Mount can be used. And for mounting on a conventional microphone stand, use the Shure A57F Swivel Adapter.

TYPICAL SM89 RESPONSE, 30 ° OFF-AXIS

Additionally, because of such off-axis characteristics, the SM89 can be used for pickup at greater angles off-axis than is possible with other shotgun microphones. This feature permits deliberately locating the desired source up to ±30° off-axis in order to ensure that an undesired source is entirely off-axis and will not be picked up. Changes in frequency response above 1,000 Hz can then be compensated by simple equalization if necessary.

Pickup (and cancellation) is symmetrical about the microphone axis; it is unchanged when the microphone is rotated about its own axis. In addition to its acoustical and electrical properties, the SM89 is extremely lightweight. This makes it easier for an operator to hold it on a fishpole for extended periods of time, for instance, during lengthy takes. The microphone length is optimized in relation to its directional characteristics and ease of handling. Its aircraft- grade materials withstand rough handling, and its unique internal construction provides excellent wind noise rejection while protecting against damage to the transducer or electronics.

The SM89 is supplied with a foam windscreen for use when the microphone is subject to quick boom motion, or when air conditioning or other indoor wind noises may be a problem. A rugged carrying case is also supplied. An optional accessory is a specially designed shock-mount virtually eliminating mechanical vibration pickup.

The SM89 is field serviceable. The handle separates by unscrewing from the head; the interconnection is gold-plated and extremely reliable.

IMPORTANT: To avoid degrading the response of the SM89, never cover its grille perforations with anything except acoustically transparent windscreen material.

SM89 specifications

The Shure SM89 is a distinguished condenser microphone that boasts exceptional performance and versatility, making it a preferred choice for both live and studio applications. This microphone is particularly well-suited for capturing vocals and instruments, owing to its precise audio reproduction and advanced design.

One of the standout features of the SM89 is its frequency response. The microphone covers a broad range, typically from 20 Hz to 20 kHz, allowing it to capture deep bass notes as well as crisp, high frequencies. This wide frequency range ensures that users can achieve a natural and balanced sound that retains the nuances of the performance.

The SM89 utilizes a highly directional supercardioid polar pattern, which is instrumental in isolating the sound source while minimizing background noise. This characteristic makes it ideal for use in live environments, where managing ambient noise is crucial. The supercardioid pattern also allows for greater placement flexibility, as the microphone can be positioned closer to the sound source without picking up unwanted noise from other directions.

In terms of technology, the SM89 features a built-in preamp circuit, which enhances its capability to capture audio with clarity and detail. Coupled with a low self-noise level, the microphone guarantees a clean signal, making it a great option for professional recording settings. The microphone's high SPL handling also allows it to capture loud sound sources without distortion, making it suitable for a variety of instruments including brass and percussion.

The SM89 is equipped with a rugged construction that is both durable and reliable. Its all-metal housing provides protection against physical damage, while the internal shock mount design helps reduce handling noise and vibrations. These characteristics are essential for mobile musicians and sound engineers who require gear that can withstand the rigors of travel and live performance.

Another notable aspect of the Shure SM89 is its versatility. It can be used in various applications, including broadcasting, sound reinforcement, and recording, allowing it to adapt to different performance situations seamlessly. Whether it’s in a studio setting or on stage, the SM89 ensures that sound quality remains a top priority.

In conclusion, the Shure SM89 is a remarkable microphone that combines advanced technology with robust design, making it a reliable choice for audio professionals. Its exceptional sound quality, directional capabilities, and durable construction make it an excellent investment for musicians, sound engineers, and content creators alike.
