Mainly used as a room mic in combination with a Scope Labs Periscope.
Selected this mic for this purpose as it is such a versatile mic (9 switchable polar patterns, 2 pads, and 3 high-pass filter options) and because of its low self-noise, high sensitivity and flat frequency response, guaranteed to work well in any room or acoustic space.
I've generally set them as omnidirectional with an HPF at either 40 Hz or 80 Hz with no pad engaged with great results. However, it all depends on the sound source(s), room, mic placement, and sonic aesthetic you plan to achieve.
The C414 has a very flat frequency response. This means the microphone will reproduce the complex room sound (in the form of a mic signal) with pristine accuracy.
The slight boost of the upper-frequency range helps enhance the “brilliance” or “air” of the acoustic space, adding an extra sparkle to the sound.
The light-weight large diaphragms of the C414 XLS capsule are very reactive and the microphone has a very accurate transient response. This helps tremendously in reproducing a precise replica of the complex sound waves in the form of mic signals at the microphone diaphragms.
