Setting button on front plate:
Push into: NOS mode.
Pull off: OS mode.

       The OS mode had include the 8x, 4x, 2x oversampling and a classis NOS mode. The sound flavor warmer while the oversampling lower, and the classis NOS mode had warmest sound favor.

        The NOS mode with push into the setting button had different arithmetic to the classis NOS mode. There are 3 different mode available , the sound not on warm side but smooth .
Users can burn in the unit more than 300 hours , try different modes while button push into or pull off, find the best sound for favorite, in future just through change the button state can had two different sound flavors .

         Even users had not change any inside setting, change the button state, the sound still had change obvious.

          R2R 2 had not applied any mute switches for keep the signal without degrade , So switch the Setting button and Select, we are advice turn the amp lower volume.
　

Jumpers setting

　

Note 1:    ON mean the jumper push on.
              OFF mean the jumper pull off.
              Please power off the unit while change the jumpers for avoid the chip damage by the static electric .
              For safe, user must pull off the AC power cable before take off the top cover.

Note 2:    If the HDMI input signal not enough good, ( it may cause by the source or the HDMI cable quality or the RF interrupt to the HDMI cable), the sound may had noise or distortion or no sound in some sampling, try to push into the jumper on DITH pins.
