Active Low-Cut Filters LC 60 U, LC 120 U
The specifications of the SCHOEPS microphones (sensitivity, noise, source impedance) remain nearly unchanged with the LC.
These low-cut filters are suitable not only for SCHOEPS microphones but also for phantom-powered microphones of other manufacturers, provided that they have a current consumption of at least 2 mA. Otherwise the maximum sound pressure level would be reduced.
The use of two LC in series is possible, particularly with SCHOEPS microphones, but is not recommended. The cutoff frequency would be raised, and the maximum output level with 12-Volt operation would be lowered. In no case should three LC be cascaded, especially if the microphones have less than 4 mA current consumption.
