Schertler Ultra low noise Microphone Input module

The Schertler Microphone Input Ultra Low Noise module is a unit for the Arthur Modular mixer that provides you with a high-end microphone preamplifier for microphones that have a weaker signal, specially designed for best possible sound reproduction. Featuring an improved Signal to Noise Ratio, with 4dB less noise, this mic input module adds further flexibility to the Arthur mixer.

The XLR input (MIC IN) can receive balanced signals from -63 dBu to +18 dBu. The GAIN knob will amplify a weak signal to a nominal level of 0dBV, or attenuate a stronger signal, so that a nominal signal of 0dB is always present at the output of the mic input amp. This Module provides you with everything you would expect on a mic in channel such as low, mid and high EQ, HPF and Aux sends.
