MENU

1. PCM filter—-L-FAST, H-FAST, M-SLOW
   L-FAST is a Linear phase FAST roll-off filter. It is the most common type of digital filter and is the most accurate and neutral acoustically. H-FAST is a Hybrid FAST roll-off filter. The length of the pre-ringing is shorter and more consistent than the length of the post-ringing which is more like musical instruments. M-SLOW is a Minimum phase SLOW roll-off filter. It has smooth signal out-of-band attenuation characteristics, and because of its in-band attenuation characteristics, it has a smoother overall sound.
   Each filter has an objective (measurable) and subjective (audible to most) effect on the sound. We encourage people to audition all three filters to determine the one that sounds the best to them. Most people will experience the differences in high-frequency reproduction where they are more readily heard. There is no “right” or “wrong” answer here, its all about personal preference, room acoustics and the characteristics of your speakers…

2. NOS MODE
   ON bypasses the oversampling feature in the DAC, sending the original digital signal straight to the modulator. This mode is useful if you want to experiment with any software-based oversampling features in products like Roon, etc. OFF engages the 8x oversampling feature in the DAC.

3. BT POWER
   BT INPUT powers up the Bluetooth input receiver only when the unit is on and ALWAYS keep the Bluetooth receiver powered up regardless of input selection.

4. VOLUME
   DIGITAL – Uses a digital volume control.
   ANALOG – Uses an analog level control. This volume control utilizes relays for optimal performance. There will be some clicking sounds from inside the unit when the relays switch as well as some audible noise that can be heard through the speakers at certain level changes. This is normal and expected behavior for this type of volume control and will not damage anything.

5. DISPLAY
   ALWAYS keeps the display on whenever the unit is on.
   AUTO OFF turns the display off after several seconds.

6. BRIGHTNESS
   “8″ is the brightest setting for the front panel display. “1″ is the dimmest.

7. TRIGGER SEL
   INPUTS & LAST
   The 12V trigger can be set to select one of the specific INPUTS or to select the LAST input used when the unit was put into standby.

8. [SOURCE] VOLUME
   This feature allows you to set the beginning starting point for the volume level for each input independently. Push the right knob to select the input to affect. Rotate the right knob to change the initial volume setting for THAT input.
   LAST sets the volume to the LAST level used when the unit was put into standby. -20, -35, -50 sets the volume level to these specific values.
   FIXED sets the unit to 0dB FS (full) gain (please use with extreme caution!).

9. INPUT 12S, COAX-1, COAX-2, OPT
   These inputs can be renamed: These inputs can be renamed: . The USB and Bluetooth inputs can NOT be re-named.
