Shotgun & Camera Microphones Buying Guide

Shotgun microphones, also called interference-tube microphones, are highly directional condenser microphones that pick up a sound source from the front while rejecting sound from the sides and rear. Camera microphones bring the same idea to a compact size that mounts on a camera or a small rig. Together they are the standard tools for film and television dialogue, documentary, news gathering, sports effects and nature recording. This guide explains how to choose from our range of shotgun and camera microphones.

How a shotgun microphone works

A slotted tube in front of the capsule lets sound from the sides arrive at different times along its length, so those sounds partly cancel, while sound from the front passes straight through. The result is a narrow pickup at medium and high frequencies. At low frequencies the tube is too short to have much effect, so most shotguns behave more like a supercardioid in the bass. A longer tube gives a narrower pickup at lower frequencies, but makes the microphone heavier and harder to aim.

Types of shotgun and camera microphones

• Full-length shotguns: the classic choice for exterior dialogue on a boom pole
• Short and compact shotguns: lighter on the boom and easier indoors, where long tubes can sound coloured in reflective rooms
• Camera-mounted microphones: small shotguns with a shock mount for the camera shoe, for run-and-gun shooting and vlogging
• Digital shotguns: AES42 microphones, some with signal processing that suppresses diffuse noise for even higher directivity
• Shotgun capsules: modular capsules that fit an existing microphone amplifier body
• MS shotgun sets: a shotgun as the mid microphone with a figure-eight side microphone, giving mono-compatible stereo

Directivity and reach

Directivity tells you how strongly a microphone favours the front. A more directional microphone picks up less room sound and background noise, so it can be placed further from the source. It also needs more accurate aiming: an actor turning away from a narrow shotgun loses level and brightness quickly. For moving dialogue, a slightly wider pickup is often easier to work with than the narrowest one.

Indoors or outdoors

Outdoors

Outside there are few reflections, so a full-length shotgun gives the best rejection of traffic, crowd and wind noise. A proper windshield is essential.

Indoors

In rooms, reflections reach the microphone from many directions and can colour a long shotgun. Many recordists use a shorter shotgun, or a supercardioid or hypercardioid microphone, on the boom indoors.

Specifications that matter

• Self-noise: low self-noise keeps quiet dialogue and ambiences clean
• Sensitivity: higher output means less preamp gain on a camera or field recorder
• Low cut and high-frequency filters: a low cut tames wind and boom noise; a high-frequency boost can compensate for a windshield
• Length and weight: they decide how comfortable a boom is to hold for long takes
• Output: analog XLR with phantom power, battery power on camera microphones, or digital AES42
• RF immunity: important near wireless systems and mobile phones

Windshields and suspensions

A foam windscreen helps against light wind and boom movement indoors. Outdoors, a basket windshield with a fur cover reduces wind noise much further, and an elastic suspension inside it isolates handling and cable noise. Choose a windshield made for the length and diameter of your microphone, and see our shock mounts and pop filters for foam covers and suspensions.

Application guide

Film and television dialogue

Boom the microphone just outside the frame, above or below the actors, and aim it at the mouth. Keep the boom operator close enough to follow the action.

Documentary and news

A compact shotgun on the camera or a short boom captures interviews and ambience when there is no separate sound crew.

Sports and outdoor broadcast

Shotguns at the field edge pick up ball and racket sounds while reducing crowd noise.

Nature and field recording

High directivity helps isolate a bird or animal from a noisy background. A good windshield and a low-noise microphone matter most.

Theatre and installation

Shotguns at the stage edge or above the stage pick up voices without being seen.

Setup and accessories

Most shotguns need 48 V phantom power from a mixer, field recorder or audio interface, connected with balanced XLR cables. Digital models need an AES42 input or a matching powering box. Add a boom pole, a suspension, a windshield and headphones, and check every take on headphones.

Common mistakes to avoid

• Aiming at the chest instead of the mouth, which dulls the voice
• Using a long shotgun in a small, reflective room
• Recording outdoors with only a foam windscreen in strong wind
• Letting the cable slap against the boom pole
• Leaving the low cut off when wind or boom noise is present
• Pointing the microphone at a noise source behind the actor, such as a road or generator
