INTRODUCTION
Congratulations on purchasing the Weiss DAC204 D/A Converter !
The DAC204 is a stereo 24 bit / 192kHz D/A converter which
supports the following conversions:
• AES/EBU or S/PDIF on RCA to analog
• AES/EBU or S/PDIF on Toslink to analog
• USB to analog
• USB to AES/EBU on XLR, RCA, BNC
There also is the DAC205 model available which does not
have the USB related features.
Features
• Inputs: There are two AES/EBU (S/PDIF) inputs on
RCA and Toslink (optical) connectors. The sampling
frequencies supported are 44.1, 48, 88.2, 96, 176.4
or 192 kHz.
In addition there is a USB input which supports
sampling frequencies of 44.1, 48, 88.2, 96, 176.4,
192, 352.8, 384 kHz plus DSD64 and DSD128.
• Outputs: The outputs are balanced on XLR con-
nectors and unbalanced on RCA connectors. The
XLR outputs have a 6dB higher level than the RCA
outputs. The XLR outputs (XLR pin 2 or pin 3) must
not be shorted to ground, i.e. there is no servo cir-
cuitry implemented.
In addition there are three digital outputs with
AES/EBU format on XLR, RCA and BNC connectors.
• Output Level: Two switches allow to set 4 different
output levels at 10dB steps.
• Sampling Rates, Word-length: 44.1, 48, 88.2, 96,
176.4, 192, 352.8, 384 kHz at up to 24 Bits are
supported. Plus DSD64 and DSD128.
• Jitter suppression: Several signal reclocking
schemes are combined for a high jitter attenua-
tion.
• Converters: Oversampling sigma delta D/A con-
verters are used. Four D/A Converters per audio
channel are operated in parallel for enhanced sig-
nal to noise performance.
• Power Supply: An external power supply is used.
The required voltage is between 6V and 9V.
• Front-panel elements:
- A power on/off switch.
- An input selection switch.
- 8 LEDs for sampling frequency indication for the
USB input.
- Two switches for DSD to PCM conversion settings
selecting the sampling frequency and the word-
length at the output of the converter.
• Back-panel elements:
- Analog outputs on XLR and RCA connectors.
- Digital inputs (one RCA and one Toslink connect-
or).
- Digital outputs (one XLR, one RCA and one BNC
connector).
- USB input connector.
- External power supply connector.
- Two toggle switches for output level setting.
