FEATURES
DC-TO-DC SWITCHING MODE POWER SUPPLY
Provides excellent power output throughout the audio bandwidth (20 Hz to 20 kHz).
its soft clipping characteristics ensure superb transient response and musicality.
FULLY DISCRETE, COMPLEMENTARY OUTPUT CIRCUITRY
For excellent reliability, superb sonic performance and high current capability for
accurate transient response.
INDEPENDENT, CONTINUOUSLY ADJUSTABLE GAIN CONTROLS FOR CH1/2
AND CH3/4
Allow different level settings for both pairs of channels.
