Ehrlund EHR-D

EHR-D is a mic special designed for Drums,
but many engineers is using it for Guitars and Horns
as well. Frequency Range 7-87kHz.


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 optimized 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.
