C220 Tube Preamplifier Features
ADVANCED VOLUME CONTROL
The McIntosh two stage VRV (Variable Rate Volume) Control is electronic in
action. It never wears or needs cleaning, and keeps channels matched to within
an amazing 1/10th of 1dB.
CUSTOMIZABLE INPUTS
The inputs can be renamed from an internal list to match the needs of the
user. Unused inputs can be deleted from the display and level matching between
inputs is provided.
POWER SUPPLY DESIGN
Multiple stages of regulation ensure top performance unaffected by power
fluctuations. The R-Core transformer radiates no hum that could otherwise
compromise the preamplifier’s low noise floor.
