The microphone types and polar patterns are detailed at the end of the cartridge list.

Uni-directional – Cartoid

The PG58, a rugged, low cost cartridge tuned to accentuate the clarity of lead and back-up vocals. Frequency range 60-15,000

Uni-directional – Cartoid

The legendary SM58® vocal cartridge is designed for professional vocal use in live performance, sound reinforcement, and studio recording. Its tailored vocal response for sound is a world standard for singing or speech. A highly effective, built-in spherical filter minimizes wind and breath”pop” noise. A unidirectional (cardioid) pickup pattern isolates the main sound source while minimizing unwanted background noise.

Rugged construction, a proven shock-mount system, and a steel mesh grille ensure that even with rough handling, the SM58 will perform consistently, outdoors or indoors. Frequency range 50-15,000.

SM86 – RPW114

The SM86 is a unidirectional (cardioid) condenser vocal cartridge for professional use in live performance. An extremely rugged cartridge, the SM86 withstands the rigors of touring while delivering a clear, studio-quality sound.

A cardioid pickup pattern isolates the main sound source while minimizing unwanted background noise. The built-in three-point shock mount minimizes handling noise, and a two-stage pop filter reduces wind and breath”pop” noise. Frequency range 50-18,000.

New Style
The SM87A cartridge is a professional-quality condenser cartridge for use in sound reinforcement, broadcasting, and studio recording installations. Its supercardioid polar pattern provides greater rejection of unwanted sound sources, making it ideal for miking individual instruments in a multi-microphone setting or for miking single sources in a reverberant or noisy environment.
An integral three-stage wind and pop filter protects against wind and breath noise. Its built-in shock mount reduces stand and handling noise. Frequency range 50-20,000.

SM87A – RPW116
Uni-directional – Super-cartoid

Wireless Beta 58A cartridge replaces the cartridge, housing assembly, and matte grille for wireless Beta 58A microphones.

Microphone types and polar patterns


A simple, rugged diaphragm/coil. It handles extreme volume levels without distortion.


A lightweight, sensitive diaphragm that precisely and smoothly captures sound nuances. It is powered by battery or phantom power supply.

Uni-directional – Cartoid

Unidirectional cartridges. These are sensitive to sound coming from only one direction. The most common type of unidirectional cartridge is called a “cardioid” because its pickup pattern is heart-shaped. It picks up most sound from the front of the cartridge, less from the sides, and very little from the rear.

Uni-directional – Super-cartoid

Supercardioid or hypercardioid cartridges offer even greater sound isolation through narrower pickup patterns.


Tailored response, tuned to accentuate specific types of voices or instruments.
