A "4x4" in the Ehrlund range: the Live approach to capture
The Ehrlund EHR-D is often described as the "4x4" of Ehrlund microphones: a more robust version better suited to live constraints, while retaining the brand's sonic DNA. Where a studio mic sometimes prioritizes finesse in a controlled environment, the EHR-D emphasizes durability, stability, and the ability to handle high levels, with simple integration into stage or home studio setups focused on direct input.
Positioned as the "Live" counterpart to the Ehrlund EHR-E studio model, it stands out by its reduced size and design tailored for real situations: quick placement, proximity to a powerful source, and the need for consistency from one gig to another. The result: a cardioid condenser microphone that handles volume confidently, remains clear in the mix, and maintains great precision even when the source becomes energetic.
For which uses and musicians?
The Ehrlund EHR-D is aimed at musicians, sound engineers, and stage technicians seeking a condenser mic capable of following expressive, percussive, or amplified instruments without saturating too quickly or losing definition. Its compact format facilitates placement in tight spaces (in front of a guitar cabinet, above a snare drum, near percussion), and its cardioid directivity helps better isolate the main source in noisy environments.
It is particularly suitable for live recordings and sessions where a dynamic and detailed reproduction is desired: guitar amps, percussion, symphonic instruments, and more broadly any acoustic or semi-acoustic source requiring presence, attack, and excellent articulation. Thanks to its ability to handle very high frequencies, it highlights harmonics and transients, an asset for instruments rich in nuances.
A design focused on precision, SPL handling, and reliability
Patented triangular diaphragm: speed and definition
At the heart of the EHR-D is Ehrlund's unique and patented triangular diaphragm. This architecture aims for a fast transient response and very fine detail capture, useful for preserving the attack of percussion, the texture of a bow, or the bite of a guitar amp. Combined with a cardioid directivity, it helps focus the capture on the desired source while limiting unwanted bleed.
Built for powerful sources
The EHR-D is specially designed for high-intensity sound sources. Its wide dynamic range and high max SPL allow close placement to the source and increased impact, while maintaining good saturation control. This handling capacity is valuable on stage, where a solid, usable, and stable signal is often sought, with comfortable headroom before clipping.
- In front of a guitar amp: close placement to capture attack and grain, with excellent clarity in the mix.
- On percussion: fast transients, clear articulation, and good handling of peak levels.
- On acoustic and symphonic instruments: high definition, detailed harmonics, and cardioid directivity useful in shared environments.

Questions frequently asked
Does the Ehrlund EHR-D support a powerful guitar amplifier?
With a maximum SPL of 132 dB at 0.5% THD and 137 dB at 1% THD, this microphone is designed for high sound pressure sources. Placing it close to a guitar cabinet captures the attack and tone.
What power supply is required for this microphone?
A 48 V phantom power supply is required, with a current consumption of 2.0 mA.
What is the frequency response and the benefit of the triangular diaphragm?
The frequency range extends from 7 Hz to 87,000 Hz. The patented triangular diaphragm is designed for fast transient response. This design enhances the reproduction of percussion attack and harmonics.
What are the dimensions of the Ehrlund EHR-D?
It measures 53 mm in diameter and 72 mm in length, with a weight of 170 g. The body is made of aerospace-grade aluminum and has a glass bead blasted finish.
Is the cardioid polar pattern suitable for stage and percussion?
The cardioid pattern helps to focus on the main source and reduce bleed in a stage environment. The stated dynamic range of 128 dB supports managing level peaks on percussion.
