Filter settings
The cut-off points of the filters are in the upper end of the frequency range.
However, due to complex technical phenomena, this will have an effect
lower in the frequency band. For further description, see the glossary of
terms. These settings are a matter of personal taste and may only offer
subtle changes. We suggest using Filter setting 1 and trying different set-
tings with various music and equipment.
Filter setting switch & LED’s - Push to advance to the next filter.
Filter settings 1–3
(low sample rates 32/44.1/48K)
1. Linear phase half-band filter
2. Minimum phase half-band filter
3. Minimum phase apodising filter
Filter settings 1–3
(medium & high sample rates 88.2/96 & 176.4/192K)
1. Linear phase soft-knee filter
2. Minimum phase brickwall filter
3. Linear phase apodising filter
The filters have a greater effect on higher sample rates because of the
higher Nyquist frequency which is ½ of the sample rate. This means the
filter has a wider frequency range in which to be active.
