General Information
Balanced Headphone Amplifier
2 x single ended normal headphone outputs)
Cross Feedback Balanced Circuit (2 output circuits for each output channel).
Realistic True Tone Preamp design which use ultra low noise / high speed IC.
Point to point wiring pattern for circuit board design to avoid common impedance.
To keep signal path as short as possible, relays are used for all signal switching
High quality metal film resistors are used
No electrolytic capacitors in the signal path
Balance Stereo inputs (XLR,TRS Combo) and Unbalance RCA input (selectable)
Hi(+10dB) /Lo(0dB) Gain mode
Master Volume Control function (variable level line outputs)
Headphone output mute function
Housed in natural walnut wooden box
