Software History
This manual is for Verona software version 1.0x.
Definitions and Abbreviations
ADC
Analogue to Digital Converter, sometimes referred
to as an A/D Converter.
AES3
A standard professional stereo digital audio format
consisting of one serial PCM data line. It uses a
balanced cable to extend transmission distance
and includes a comprehensive messaging system.
DAC
Digital to Analogue Converter, sometimes referred
to as a D/A Converter.
dB
A relative signal level or ratio in decibels. The
context may indicate the reference level.
dB0
Level in decibels, referred to a full scale sine wave
in a sampled system. So, 0dB0 is full scale.
dBu
A signal level relative to 0.775V rms, making no
allowance for external loading.
DDC
Digital to Digital Converter, sometimes referred to
as a D/D Converter.
DSD
Direct Stream Digital - a single bit digital audio
format, sampled at 2.822MS/s.
kS/s
Sample rate in kilo-samples per second. This
replaces kHz, which is technically incorrect when
referring to sample rates.
SDIF-2
Sony Digital InterFace – a stereo digital audio
format consisting of 2 serial PCM or DSD data
lines. Usually used with a Word Clock.
SPDIF
Sony / Philips Digital InterFace – a stereo digital
audio format for consumer equipment, consisting
of one serial PCM data line. Similar to AES3, but
unbalanced and with different messaging.
Word Clock
A synchronisation signal consisting of a square-
wave, the frequency of which is the sample rate.
Usually transmitted through co-axial cable and
BNC connectors.
