Those who make recordings with microphones know it too well: the annoying low-frequency wind noise, the handling noise coming from boom operation, and solid-borne infrasonic noise. These noises can make a recording unusable since not every microphone input offers sufficient headroom or an adequate filter for removing them. Even when the audible portion is already quite disturbing on its own, the degree of the low-frequency signals can't be perceived to its full extent due to the insensitivity of the human ear in this range at low levels. Hence the user is sometimes surprised when the input stage gets into audible overload. Perhaps there is even the suspicion that the microphone might be defective. Schoeps attacks this problem with an electrically active filter. It utilizes a third-order high-pass filter (18 dB/oct.) with a low output impedance, so long cable runs don't present a problem. Although the LCs have been designed mainly as an accessory for the CCM Series compact microphones, their application is not restricted to Schoeps but can be used with phantom-powered condenser microphones of other manufacturers as well, provided that their minimum current drain is at least 2 mA. In use, it is inserted in the microphone line, where it is phantom-powered by 12 V or 48 V. The LCs may even be used in series: Two of them form a 6th order filter (36 dB/oct.; further cascading is possible but not recommended.) The LC is available in two versions: the LC 60 U with a 60 Hz cutoff or the LC 120 U with a 120 Hz cut off frequency, both with a slope of 18 dB/octave. |
