USB-Audio
Support DSD512 high specification digital audio format
Premium Phono phono interface
MM (moving magnet) MC (moving coil) two vinyl cartridges are easily compatible.
SW-OUT ultra-low output
Balanced and unbalanced two sets of bass output interfaces, which can be connected to active subwoofers at will, to meet the special needs of more heavy woofer enthusiasts
Bi wiring partial
Standard mode and bi-wiring are two ways of playing, which will further give full play to the excellent performance of power amplifiers and speakers!
Three working states
CLASS A——The warm music flows slowly, refreshing and refreshing.
CLASS AB—Orchestra, symphony, chorus, all kinds of dynamic scenes are vividly displayed.
AUTO—Only one setting is needed to bring the power amplifier working state to your satisfaction in various music scenes.
High-performance USB decoder chip CT7601PR
DSD decoding: DSD512, DSD256, DSD128, DSD64
PCM sampling rate: 32bit/768KHz
The whole machine shares 9 TI OPA1656 op amps to form full balance and buffer amplification
High power famous tube
The whole machine adopts 24 high-power Toshiba 1941/5198 transistors to amplify the output
Digital volume control core
Selected NJW1195A volume control chip, with -118dB ultra-low noise 0.5dB step adjustment accuracy, its distortion, signal-to-noise ratio, separation and other indicators are very good, adjustment and control are more accurate, more durable, and fearless wear.
Sub-chamber and sub-chamber structure
Five-box sealed structure, input, power supply, energy storage, amplification and partition shielding, greatly reduce the free electromagnetic waves in space, effectively reduce the interference of signals in the machine, and make the bottom noise of the machine reach ghostly silence.
