insert modes check the instructions further down.)
Note that if a computer is connected to the DAC202 via
Firewire, the Sync Source parameter has to be selected
from the Weiss Firewire IO control panel on the
computer!
For all possible input sources (Firewire, AES(XLR), SPDIF(RCA)
and SPDIF(TOS)) the following sync sources can be selected:
- XLR: This selects the XLR input as the synchronization source.
- RCA: This selects the RCA input as the synchronization source.
- Toslink: This selects the Toslink input as the synchronization
source.
- WC BNC: This selects the BNC connector at the rear of the
DAC202 as the synchronization source. If the DAC202 is used in
dual wire mode read the instructions for the dual wire mode
regarding external synchronization.
- 1394 bus: This slaves the DAC202 clock to the Firewire bus.
This setting is only required if more than one DAC202 unit is
connected to the same computer for multichannel playback. In
that case one of the DAC202 is the master clock and the other
DAC202 units have to be slaved to that master DAC202. This is
done by setting the slave DAC202 to “1394 bus”.
- Internal: The DAC202 generates the sampling rate clock
internally. Note that in this mode the source has to be
synchronized to the internally generated sync. With Firewire as
input source this is done automatically via Firewire. With the
other inputs the source, e.g. a CD transport has to by
synchronized via e.g. the sync out
BNC connector at the back of the DAC202.
4.) Sync Rate: Depending on the Sync Source selected
there is either the sampling rate shown or the word “autolock”.
If the sampling rate is indicated (i.e. “Internal” is selected as
Sync Source) then it is possible to change the rate to the
appropriate value. Usually the sampling rate is set by the player
program running on the computer in that case.
5.) LCD Bright: sets the LCD brightness
6.) LCD Dim Lev.: sets the LCD brightness when in
dimmed mode. The dimmed mode is entered after some time of
inactivity from frontpanel knob or remote control.
7.) Dual Wire: Disabled means that the signals at the XLR
or RCA or Toslink inputs are treated as single wire AES/EBU
signals with sampling rates up to 192kHz. Also the XLR and RCA
outputs operate in single wire mode up to 192kHz. If enabled,
the XLR and RCA inputs (or outputs) are a dual wire pair, i.e.
the XLR connectors carry the left channel and the RCA
connectors carry the right channel. This is the case only for
sampling rates of 176.4 or 192 kHz though! All other sampling
rates are disabled for external sync sources and are operated in
single wire mode for internal sync.
8.) DW WCLK: Means Dual Wire Wordclock. Can be
audiorate or halfrate. Audiorate means that the wordclock signal
at the BNC connectors (input or output) is at the actual audio
sampling rate when the unit operates in dual wire mode. I.e.
the wordclock rate at the BNC connectors is:
Audio Sampling rate: BNC connectors rate:
44.1 44.1
48 48
88.2 88.2
96 96
176.4 176.4
192 192
If “halfrate” is selected the wordclock rate at the BNC
connectors is:
