Shure SM86 Condenser Vocal Microphone

The Shure SM86 is a unidirectional (cardioid) condenser vocal microphone designed for professional use in live performance. It combines the rugged durability associated with the Shure SM series with the enhanced sensitivity and frequency response of a condenser capsule to provide a studio-quality sound on stage.

Overview

The Shure SM86 is engineered to offer a high-fidelity alternative to standard dynamic handheld microphones. While many stage microphones prioritise extreme durability through dynamic designs, the SM86 utilises a condenser capsule to capture finer details and the natural articulation of the human voice. It is designed to withstand the rigours of touring while delivering a more authentic representation of the performer's vocal characteristics.

Engineering and Design

Built to Shure's rigorous testing standards, the SM86 features a robust construction that differentiates it from delicate studio-only condensers. A key functional component is the built-in three-point shock mount, which minimises handling noise, and a dual-layered pop filter that reduces wind and breath noise. These features ensure that the sensitive condenser element can be used in high-energy live environments without compromising audio clarity.

Sound Character

The SM86 is characterised by a crisp, detailed high-end and a smooth frequency response. Unlike traditional dynamic microphones that may sound muffled or overly compressed, the SM86 preserves the nuances of a vocal performance. The cardioid polar pattern provides excellent isolation, focusing on the primary sound source while reducing the pickup of unwanted background noise and feedback in live settings.

Suitability and Use Cases

This microphone is particularly suited for lead vocalists who require the clarity of a condenser but the reliability of a handheld stage mic. It is ideal for performers transitioning from studio environments to the stage who find dynamic microphones lacking in detail. Furthermore, its ability to handle high sound pressure levels makes it versatile enough for various vocal styles, from delicate jazz to powerful pop performances.

Market Comparison

Within the Shure ecosystem, the SM86 sits as a more detailed alternative to the legendary SM58 dynamic mic and a more accessible option compared to the KSM series. When compared to high-end studio options like the Neumann TLM 102 or TLM 103, the SM86 offers a handheld form factor better suited for movement. It also provides a different sonic profile than headworn condensers like the Shure SM35-XLR or the Audix HT2, offering a traditional handheld experience with superior isolation.

Frequently asked questions

What type of microphone is the Shure SM86?
The Shure SM86 is a handheld condenser microphone. It requires phantom power to operate and uses a sensitive capsule designed to capture more detail than standard dynamic microphones.
Does the Shure SM86 require phantom power?
Yes, as a condenser microphone, the SM86 requires phantom power (typically 11-52V DC) provided by a mixing desk or audio interface. It cannot function without this power source.
Is the SM86 suitable for live performance?
Absolutely. It is specifically designed for live use, featuring a rugged build and a built-in shock mount to reduce handling noise, making it more durable than many other condenser mics.
How does the SM86 compare to the SM58?
While the SM58 is a dynamic microphone known for its warmth and extreme ruggedness, the SM86 is a condenser that provides greater high-frequency clarity and a more detailed, 'studio-like' sound.
What polar pattern does the SM86 use?
The SM86 utilizes a cardioid polar pattern. This unidirectional design helps to isolate the main vocal source while rejecting sound from the rear, which is crucial for preventing feedback on stage.
What is the typical price for a Shure SM86?
The Shure SM86 typically retails for approximately GBP 171. This places it in the mid-range of professional vocal microphones.
Does the SM86 have a built-in pop filter?
Yes, it features a dual-layered pop filter. This design helps to reduce plosives (p and b sounds) and wind noise during close-up vocal performances.
Can the SM86 be used for studio recording?
Yes, the SM86's condenser capsule makes it a viable option for home and professional studios. While it is designed for stage use, its detailed response is effective for recording vocals and acoustic instruments.
How durable is the SM86?
The SM86 is built to Shure's legendary standards for durability. It has undergone rigorous testing similar to Shure's flagship models to ensure it can survive the demands of frequent touring.
How does it handle background noise?
Thanks to its cardioid pickup pattern, the SM86 is effective at rejecting off-axis sound. This makes it a strong choice for loud stages where bleed from other instruments needs to be minimised.
What is the benefit of the three-point shock mount?
The internal three-point shock mount is designed to decouple the capsule from the microphone body. This significantly reduces the transmission of physical vibrations and handling noise to the audio signal.
Is the SM86 better for certain vocal types?
It is particularly well-suited for vocalists who want to preserve the 'natural articulation' and finer details of their voice. It offers a more authentic representation than most standard dynamic microphones.
