Special Features

All inputs are controlled by relays, therefore very short signal paths.
Symmetrical circuit design from input to output
DC servo system for continuous direct coupling from MC input to output
Pre-amplifier with very wide dynamic range
Both stereo channels are built independently from each other
Brushed solid aluminum front panel and side panels
Computer-controlled controls
Push-button control for input selection
Additional output for active subwoofer amplifier with variable crossover frequency
