Active Low-Pass Filter LP 40 U

The low-frequency response of any directional microphone is inherently inferior to that of omnidirectional (pressure) microphones. When using directional microphones, one can extend the low-frequency response by adding in signals from omnidirectional microphones that have been low-pass filtered with a device such as the LP 40.
