Frequently Asked Questions

It offers a very competitive price-to-performance ratio, delivering accuracy and low noise often found in significantly more premium models.
While technically capable, its flat response isn't flattering for creative recording; it’s designed for objective measurement, not artistic coloration.
Earthworks recommends a stable 48V phantom power supply to ensure consistent and accurate measurements – avoid variable or noisy power sources.
