OWNERS MANUAL FOR WEISS DAC202 D/A CONVERTER

Operation / Installation
Unpacking and Setup of the DAC202
Carefully unpack the DAC202. The following items should be
enclosed:
• The DAC202 D/A Converter unit
• The IR remote control unit
• A CD with the necessary Firewire drivers for Windows and
OSX and with the audio files for the bit transparency check
• This Owners Manual
• A Certificate of Guarantee
Firewire Connection
Before connecting the Firewire cable between computer and
DAC202 unplug both the computer and the DAC202 from the
mains power.
Mains Connection
Before connecting the mains cable make sure the label on the
back of the unit (near the mains inlet) shows the appropriate
mains voltage. If this is not the case then the proper mains
voltage may have to be selected with a jumper cable inside of
the DAC202 unit. Contact your dealer in that case.
First time operation
After connecting the necessary cables (the DAC202 can also be
operated without computer, e.g. by connecting a CD transport
to one of its inputs) switch on the unit by pressing on the rotary
encoder knob.
Note that when power is applied to the DAC202 the blue
standby LED is lit. When the DAC202 is switched on, the
blue LED is turned off and after a short while the LCD
screen comes on.
Note that if a computer is connected to the DAC202 via
Firewire, the sync source and sync frequency (if applicable) has
to be selected from within the Weiss Firewire IO window on the
computer. The selection from the DAC202 screen does not work
in that case!
After a short while the LCD screen lights up and shows the basic
start-up screen, e.g. like shown here.
In the upper left corner the volume in dB (decibel) is shown, a
value of 0.0 is maximum volume. Below the dB figure there is a
bar, which also represents the volume.
In the upper right corner the polarity is shown with the Greek
character “phi” which is used for the phase angle in electrical
engineering. “Phi +” means the signal is not inverted, “phi –“
means the signal is inverted (both channels).
In the lower right corner the selected upsampling filter type is
shown. It can be “A” or “B” and for later software versions it
may be even “C”, “D” etc.
Below the volume bar the current input source is shown. It can
be “Firewire”, “AES (XLR)”, “SPDIF (RCA)” or “SPDIF (TOS)”.
These are the four input sockets to the DAC202, i.e. Firewire,
XLR, RCA and Toslink (optical).
Below the input source the sampling rate is shown, if there is a
valid signal present at the selected input, otherwise “unlocked”
indicates that there isn’t a valid input signal.
Rotating the knob causes the volume control to change the
value.
