Specifications and product details are subject to change without notice.

Definitions/explanations for technical terms will be found in a large Glossary on this site. Links have not been included within the text on most pages, to keep them as readable as possible; but a Glossary button appears in the Navigation Bar at the top of each page.


Microphone Conditions (Additional comments)


Open Circuit Sensitivity At 1 kHz, with 1 Pa (Pascal) = 94dB sound pressure level (SPL), measured at diaphragm. Stated in dB re 1 volt, and in millivolts.

Noise, typical A-weighted, using Audio Precision System One measurement system.

Weight Stated for the microphone only, without accessories, and without attached cable/power module, if applicable.

Frequency Response (Graph) Shows mic output versus frequency with a constant sound input level from a source 0.5 meters from the diaphragm. Each vertical division in the graph is 10dB. A dashed line, if present, shows the effect of a low-roll-off (hi-pass) function.

Polar Pattern (Graph) Shows mic output versus angular direction of the sound source, with a constant sound input level at 1 kHz, at a constant distance from the diaphragm. Zero degrees (0) is the "front" of the mic. Each circular division in the graph is 5 dB, beginning from the 0 point and counting inward.

Headphone/Headset Conditions (Additional comments)


Headphone Sensitivity Input of 1 milliwatt at 1 kHz into rated impedance; output in dB SPL, using a Brel & Kjaer 4153 coupler.

Maximum Input Power At 1 kHz into rated impedance.

Boom Mic Sensitivity Open circuit, at 1 kHz, with 1 Pa (Pascal) = 94dB sound pressure level (SPL), measured at diaphragm. Stated in dB re 1 volt, and in millivolts.
