Fade In Moreover additional prerequisites speak for the employment of high-perform- ance analog technology: Master Fader The number of necessary AD/DA conversions should be reduced to a minimum. With the MMC 2, digital sources can be connected to a digital router, which outputs the selected source through the preferred DA converter. This ensures that the sound quality remains comparable and is not affected by converter differences. High quality analog outboard processing consistently proves

Control Elements Monitor Level The Monitor Level is controlled with a custom-made eight-tiered potentiometer. The MMC 2 does not employ DACs, step ladders or VCAs for this function, and the specifi ca- tions of this potentiometer are substantially better than either of these other options ever could be – the maximum tolerance is ‹ 0,5 dB over the entire control range. The control range reaches from -∞ dB to +4 dB. Monitor Level Master Fader Master Fader This fader features the same potentiomet
