Dither
The DS1-MK2 v2.0 is able to apply POW-R type
dither algorithms to avoid distortion when re-
quantizing from 24bit to 16bit or 20bit output
word length (see TECHNICAL DATA for dither
specifications).
To toggle dither on/off, press key D twice. To see
dither status refer to the status display (see
Fehler! Verweisquelle konnte nicht ge-
funden werden. p. Fehler! Textmarke
nicht definiert.).
Word Length
To set output word length, press key D and select
the appropriate wordlength.
Setup
Press key D then chose the setup menu. This
leads to the menu where the type of POW-R
dither can be chosen (see TECHNICAL DATA
for dither specifications). Also selectable is:
Auto-Blacking
If auto-blacking is activated by marking the “0 IN
à 0 OUT“ option, dither will be turned off if the
input signal is zero As soon as the input signal
changes, dither will be turned on again. This en-
sures that pauses between programmes are still
digital zero, even if dither is activated.
Display Resolution
The magnitude of the overall frequency response
of the EQ1 is drawn on the LC display. This im-
mensely facilitates filter parameter adjustment
because it takes one look to see what the equal-
izer is doing instead of having to work it out from
the parameter values.
To obtain the maximum benefit from the graph,
set the vertical display resolution to a range that
just covers your settings. There are four ranges
available:
± 6dB, ± 12dB, ± 18dB, ± 24dB
To change the display resolution, press the
“menu” key, then select “Display”. Choose a
range that suits your curve and press the “menu”
key again to return to the status display.
LCD Contrast
To change the display contrast, press the “menu”
key, then select “Display”. Adjust contrast with
the “gain/ data” encoder.
EQ Bypass
The EQ1 can be completely bypassed with the
green “bypass” key below the mains switch. If the
“bypass” key is lit, the EQ1 is absolutely trans-
parent, making the output signal bit equal to the
input signal.
While bypass is active (key is lit), the EQ1 works
in preview mode. This allows you to change pa-
rameters without actually affecting the audio sig-
nal. The frequency curve is drawn outlined over
the flat bypass curve, so you still get the advantage
of the graph when modifying parameters.
As soon as bypass is deactivated, the outlined
curve takes effect.
