Which Upgrade is best for my application ?
The basic MOD keeps all features intact and reduces the mic preamp hiss
thru the XLR connections as well as the built in mics.
The Advanced MOD keeps the line input and limiter/ALC circuit intact but removes the built in mic, DL mono and filters. This circuit change along with parts upgrade significantly reduces the mic preamp hiss. It also uses very fast, very low distortion chips for the mic preamp as well as ultra high quality input capacitors. The result is a level of speed, detail and transparency that far exceeds that of the stock machine. The gain range on the mic preamp is -55dB to -15dB, a range of -60dB to -20dB available upon request.
