OWNERS MANUAL FOR WEISS DAC202 D/A CONVERTER

Date: 03/10
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 where there weren’t done any
changes to the parameters via the frontpanel
knob or the 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 continue to work in single
wire mode.
8.)
DW WCLK: Means Dual Wire Wordclock. Can be
audiorate or halfrate. Audiorate means that the
