Ehrlund EHR-M1

A Version Designed for the Stage, Continuing the Ehrlund Range

The Ehrlund EHR-M1 carries the DNA of the Ehrlund EHR-M microphone, making it more reliable to use in concert conditions. This "Live" version retains the audio performance that made the original model renowned, while integrating better impact resistance and a dust filter designed to withstand field constraints: quick handling, stage changes, frequent transport, and particle-heavy environments. The result is a premium microphone, built to leave the studio and remain reliable night after night.

For Whom and What Uses: Capturing Natural Sound Live and in Demanding Recording Situations

The EHR-M1 is aimed at musicians and sound engineers who want a natural and detailed capture, without harshness, and with strong clarity in the mix. Its cardioid directivity helps focus the pickup on the source, an important asset on stage to better manage ambiance and monitors. Thanks to its strong output signal, it integrates easily into a live console, preamp, or audio interface, while maintaining a comfortable headroom for dynamic sources.

Its "broad and smooth" rendering also makes it relevant for recording when seeking air in the upper spectrum and a solid foundation in the lows. In practice, it targets takes where you want to hear the texture and relief, while keeping a sense of transparency and precision.

What Makes the Difference: Triangular Diaphragm, Low Noise, and "Live" Design

A Patented Triangular Diaphragm for Definition and Openness

The heart of the EHR-M1 is its unique triangular diaphragm. This design aims for a very "clear" reproduction, with a response that is both wide and smooth. The stated frequency range is exceptionally broad, resulting in a sensation of extension in the extremes and the ability to reproduce micro-details (attack, articulation, breathing of the performance) very clearly.

A Very Low Noise Phantom Power Stage

The microphone is paired with a low-power, very low noise phantom power amplifier. The goal: to maintain a low noise floor and comfortable dynamics, while keeping a high output level. In real situations, this can reduce the need to increase gain, thus limiting cumulative chain noise, especially on subtle takes.

Optimized for the Stage: Robustness, Compactness, Protection

The EHR-M1 version emphasizes live reliability: a shockproof "shell" and an effective dust filter complete the design. Its compact format facilitates placement, whether on a standard stand, in a tight environment, or amid a busy set. The metal construction inspires confidence, and the 3-pin XLR connector conforms to stage and studio standards.
