CMC 6 linear (No. 193002)

The CMC 6 microphone amplifier has a lower cutoff frequency of 20 Hz to keep infrasonic noise of various origins, e.g. due to air currents or vibrations, low. However, when using pressure receivers, there may be a desire to record frequencies below 20 Hz without attenuation. The CMC 6 linear allows this. On request, it can be supplied with a lower cut-off frequency of 10 Hz. Caution: Since pressure receivers also pick up infrasound down to very low frequencies, even noise from ventilation systems or rail vehicles can become problematic in large rooms, e.g. churches. The danger is even greater with pressure gradient receivers. Although they transmit the lowest frequencies from the sound field only weakly, they react all the more violently to other, undesirable stimuli such as air movements and structure-borne sound. Although these signals are outside the audible range, they can cause strong, audible distortion due to overdriving, especially of inputs with undersized transformers.
