Sennheiser MKH 8040 Compact Cardioid Condenser Microphone (Stereo Set)

The Sennheiser 506290 is a stereo set built around two MKH 8040 cardioid condenser microphones, designed for engineers who want transparent sound and an easy-to-place rig for studio sessions, film shoots, or field recordings.

Each MKH 8040 uses a cardioid pickup pattern that focuses on what is in front of the capsule while damping side and rear noise. That focus lets you work in rooms that do not have perfect acoustic treatment or on busy sets where spill can be a problem.

The capsules handle peak levels up to 142 dB without audible distortion, and their frequency response stretches from 30 Hz to 50 kHz. Those figures mean you can capture the full impact of a drum kit, the resonance of a grand piano, or the airy detail of a string ensemble with equal confidence.

A self-noise figure of only 13 dB A keeps quiet passages clean, so subtle ambience and soft classical passages remain free of hiss. Each mic measures only 2.95 inches in length and weighs less than 2 ounces, making the pair a smart choice for discreet placement on a boom pole, a stereo bar, or inside a Decca Tree.

The set arrives ready for work with two mic heads, two XLR output modules, clips for secure mounting, foam windscreens for basic wind protection, and a transport case that keeps everything organized between sessions.

Both microphones run on standard 48-volt phantom power delivered through the XLR connections you already use in the studio or on location.
