> Are also the "virtual faders" (MOTU's CueMix) considered to be attenuators? I would assume that Cuemix does all of its processing, including changes in volume, within the digital domain. As such I wouldn't really call this attenuation or amplification. Adjusting the faders on a virtual set up is altering the final signal level but its a mathematical process on data blocks rather than a change in the signal's voltage. Interestingly, all this talk of the CR1604 made me go and have a look at the schematic of that venerable Mackie desk. It's channel fader does indeed control the gain directly of the fader amplifier rather than just attenuate. It's rather an unusual topology with a maximum gain of +20dB or so at the top end. It uses a shunt method of signal control - where the excess audio signal is increasingly shorted to ground (0V) the lower down the fader is. The later CR1604VLZ uses the more traditional attenuator (potential divider) design followed by a +10dB amplifier. Tony www.oakleysound.com
