The Series Black LA-120 Small-Diaphragm FET Condenser Microphone Pair from Lauten Audio features two microphones with ultra-low-noise JFET amplifiers, interchangeable 17mm pressure-gradient condenser cardioid and omnidirectional capsules, and electronically balanced outputs. Each mic has a 50 to 150 Hz low-cut filter, to reduce boomy lows or low-end room rumble, and a 10 to 15 kHz high-cut filter, to help tame bright rooms and sources. The combination of these two, with easy-to-engage switches, eliminates the common problems in home-, basement-, or bedroom-recording environments.
