Our most robust microphone. Designed specifically to block out unwanted sounds from sides and back, the EHR-D is a microphone designed for loud sound sources, tentatively for drums, horns and guitars. The housing is made for the rough life of being on the road.


The EHR-D is the smallest, lightest and most durable of our large diaphragm condenser microphones. It is optimised for live performances and to make recordings of percussion, strings, woodwind and other types of instruments. The coarse dirt filter, robust design and compact size makes it perfect for musicians on tour. It has a slightly narrower polar pattern than true cardioid which makes it great for miking instruments without getting other sounds “bleeding in” from the sides.


• Large diaphragm condenser microphone • Patented internal amplification and power circuits • Patented triangular membrane • Optimised for live environments and instrument recording • Transparent and natural sound • Great low-noise performance • Phase and frequency linear internal amplifiers • Compact size and weight • Built-in coarse dirt filter • Durable design, built to endure the rough life on tour • Slightly narrower cardioid pattern resulting in less “bleed” from the sides • Bass frequencies are picked up in an accurate way even at some distance • Natural reproduction of fast transients • Handles sound pressure up to 137dB for <1% THD • Colouring of sound is negligible and true to the original source • Frequency range spans from infrasonic bass to ultrasonic treble • Low energy consumption, ~2.0 mA • No pre-filtering needed, Ehrlund microphones are made for flat EQs • Each and every Ehrlund microphone is stereo matched with its own model • Handles all impedances without altering frequency or phase
