EVO PHONODAC TWO
DXD-DSD A-TO-D AND D-TO-A CONVERTER – PHONO PREAMP
REVISION P A – JULY 2016
R
MPX filter is a notch filter (it only deletes one frequency) centred at 19kHz. It's useful to
delete the stereo sub-carrier residuals from stereo FM signals. The filter has no effect on
the audio signal, as FM stereo bandwidth is, by standard, limited to 16kHz. This item
relates to 3 values:
• BACK: go to level 1;
• ON: the MPX filter is on (19kHz will be deleted);
• OFF: the MPX filter is off..

8.9. Phono equalization (EQ Phono)

This item has several values, please see details in Chap. 9:

8.10. ADC resolution (ADC RES)

This item relates to 5 values:
• BACK: go to level 1;
• 32 bit: analog input signal will be quantized to 32 bits;
• 24 bit: analog input signal will be quantized to 24 bits;
• 20 bit: analog input signal will be quantized to 20 bits;
• 16 bit: analog input signal will be quantized to 16 bits;.

8.11. ADC sampling frequency (ADC FS)

NOTE: this item is only relevant with the EVO PHONODAC TWO
standalone mode (that is, not connected to a computer by USB), otherwise the
sampling frequency will be set by the computer.
This item relates to 9 values:
• BACK: go to level 1;
• 384.0kHz: analog input signal will be converted at 384kHz;
• 352.8kHz: analog input signal will be converted at 352.8kHz;
• 192kHz: analog input signal will be converted at 192kHz;
• 176.4kHz: analog input signal will be converted at 176.4kHz;
• 96kHz: analog input signal will be converted at 96kHz;
• 88.2kHz: analog input signal will be converted at 88.2kHz;
• 48kHz: analog input signal will be converted at 48kHz;
• 44.1kHz: analog input signal will be converted at 44.1kHz;.

8.12. ADC input gain (ADC GAIN)
