The following table shows the filter stop band attenuation:
Roll-off at 20kHz
Roll-off at 22kHz
Ultimate roll-off
We encourage you to experiment with the filters to determine which sound best to your ears and
using your source equipment/programme material. The DacMagic remembers and recalls the selected
filter type for each input individually, making it possible, for example, to select Steep for the USB input
and Linear Phase for Digital Input 1, and so on.
