Marantz PMD-671

Performance Enhancements Available :

Basic MOD
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 Basic MOD PMD671 is priced at only 999.00
Advanced MOD
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.
Advanced Concert MOD
