The Schoeps LC 120 U Active Low-Cut Filter is an electronic filter that can be inserted anywhere in the microphone cable path. Under extreme conditions the LC 120 U can be used, though it may have an audible effect on the sound of a voice. This filter can help prevent overloading the input circuit to which a micro phone is connected. The LC 120 U features 120 Hz cut-off frequency. The specifications of the Schoeps microphones (sold separately) such as sensitivity, noise, source impedance, remain nearly unchanged with the LC 120 U.
This low-cut filter is suitable not only for Schoeps microphones (sold separately) but also for phantom-powered microphones (sold separately) of other manufacturers, provided that they have a current consumption of at least 2 mA. Otherwise the maximum sound pressure level would be reduced.
Note! The use of 2 LC in series is possible, particularly with Schoeps microphones (sold separately), but is not recommended. The cut-off frequency would be raised, and the maximum output level with 12V operation would be lowered. In no case should 3 LC be cascaded, especially if the microphones have less than 4 mA current consumption.
