Independent shopping perspective
The Korena take
The MM 1 is a condenser measurement microphone for making acoustic decisions from repeatable readings. Its omnidirectional pickup, diffuse-field calibration at 90°, and ±1.5dB tolerance from 50Hz–16kHz support room analysis, studio tuning, PA alignment, and sound-reinforcement work. The slim metal body and recessed capsule are designed to minimize the microphone’s own effect on the sound field, making placement straightforward around monitors, PA systems, or environmental measurements. It connects by 3-pin XLR and requires 12–48V phantom power.
Strong match
Who this is for
- Studio-monitor and room-acoustic measurements where diffuse-field calibration supports informed tuning decisions.
- PA alignment and sound-reinforcement analysis using frequency-response and sound-pressure-level monitoring.
- Positioning a compact measurement microphone in complex acoustic environments.
