Hi Tony So are there any audio benefits of that CR1604 topology (as well as = presumably technical limitations)? I can see how it can be a 16-channel overdrive box, but I don't think = that is what Eno would have been after.

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=20 this attenuation or amplification. Adjusting the faders on a virtual set = up is altering the final signal level but its a mathematical process on=20 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=20 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=20 or so at the top end. It uses a shunt method of signal control - where=20 the excess audio signal is increasingly shorted to ground (0V) the lower = down the fader is. The later CR1604VLZ uses the more traditional=20 attenuator (potential divider) design followed by a +10dB amplifier. Tony www.oakleysound.com
