8X96 ADC – Features
8X96 ADC - Special DIP Switch Options
Both ADC and DAC units are equipped with a dip switch mounted on the main
motherboard next to BNC wordclock jack. This switch allows tailoring certain features of
the A/D converters to the actual system setup.
Bold are factory default settings

Description:
ADC dither for 16/20 out- when 16 or 20 bit conversion is selected appropriate dither is
applied
Supershaper™ for 16/20 out – when 16 or 20 bit conversion is selected the
SuperShaper noise shaping is engaged. For best transparency we recommend using it in
conjunction with dither. With this , the 9
th
order noiseshaper is very similar to Po-wr ™
noiseshaping algorithm #3.
WCK I/O =44/48 for 88/96 data– This setting facilitates synchronizing the converter
working in 88/96kHz mode with external equipment working in 44/48k mode. For
example Tascam machines require 44/48k wordclock , when they record 88/96k in
bit/sample split mode. This setting affects both wck in and out.
