FRONT PANEL CONTROLS
DSD and 128xDSD
(hi-speed) feature
can be enabled by
installing the DSD
DIOCARD.
Pressing and holding
button
enables or disables
external sync. Toggling
this switch selects the
source of external clock.
Ext.Clock Source
WCK switch allows
wordclock (both in and
out) to be a division of
sampling frequency.
For example- when
FS/4 is selected, the
converter will operate
at FS=176.4k while the
wordclock is 44.1k.
Source to Digital
Out- See Signal
Flow on pg 6.
Source to Analog
Out- See Signal
Flow on pg 6.
Meters- Selects
signal displayed
by Meters- either
ADC or DAC.
Red meter LED
is a full scale
signal at 1
sample or more.
We do not
recommend
peaking at red.
Stereo Output selector determines
what is present on stereo XLR
outputs and headphone. It can
either be any pair of DACs or L/R
sum of them (odd channels
summed to L and even to R) or
Mono sum of all 8 chan.
Holding this button selects Thru
Knob function which routes the
XLR output via volume attenuator.
These outputs are typically
connected directly to power amp or
powered speakers providing hi-
fidelity short signal monitor path.
Hi- Fidelity, high drive
headphone out can drive any
type of headphones with
ultimate fidelity. It's able to
provide up to 1 Amp of instant
current drive. The headphone
out is the same as XLR and
it's always routed through the
knob.
Precision 1dB steeped
attenuator features a
precision 24 step switch and
precision resistor ladder
resulting in very accurate
level monitoring for mastering
purposes.
Mute button mutes
main XLR outs.
Sample Rate switch
toggles btwn sampling rates
for PCM and if DSD option
is installed, sets the unit to
DSD or 128xDSD mode.
This switch sets sample
rate for both AD and DA
and has to be set manually
even if ext. clock is applied.
In such case it has to be the
nearest approximation of
applied clock (or its
multiplication if FS/2 or
FS/4 is selected).
