SLOW are available.
By pressing the two menu buttons CONV (k) once or

sa mple rates and filter sett ings for the selected
digital input. The setting is saved for each individual
input until the next manual change.
N ATIVE i nd ic at es that t he sa mpl e rat e of t he
applied signal is processed directly. CNV stands for
'conversion' and means that it upsamples or down -
samples to the desired and displayed sample rate.
The filter settings FAST and SLOW can be selec -
ted according to your tonal preferences. Depending
on the signal played back, different filter settings
can produce the most preferable sound.
Technically speaking, FAST means steep filtering
at the band end with a flat amplitude response, but
with strong phase rotation. By contrast,
SLOW fil -
ters less steeply and already has a small amplitude
drop before the end of the frequency band, but a
lower phase shift. The selected filter setting only
applies to the current input and remains stored even
after the device has been switched off. It can be
changed at any time by pressing the menu buttons
CONV (k) again.
