Tips and Hints
•
DA53
has an integrated upsampler, a state of the art 24Bit/195kHz D/A-converter *) and a current
injection analog stage with LEF output for the backside analog output connectors. Whenever a balanced
XLR connection is available it is preferable to RCA.
•
Use high quality cable for connection.
•
Digital signals connected to TOSLINK, COAX or AES/EBU can be transmitted to a computer by USB 1.1,
limited to 48 kHz input sampling frequency.
This function might be blocked by copy protection of your source, e.g. CD-Player!
•
DA53
offers different settings for digital filter, oversampling and dither to make your own choice.
Recommended default
: Set “Digital Filter” (DF) to “SOFT”, “DITHER” to “ON”, and “ΔΣfs“ to“32fs“
•
To keep it clean use only a soft cloth and never use any solvents or abrasives. Dust and fingerprints
may be removed with a soft cloth moistened only with a few drops of water.
*) 195 kHz is not a printing error! We chose this frequency for internal operation to avoid intermodulation
with any incoming sample frequency.
Cautions Regarding Handling
