The Progress Indicator
The progress indicator of the Cyrus DAD7 provides a
useful graphic alternative to the conventional elapsed time
display. Two modes of operation are available, depending
on which time display is selected:
i). When the time display is set to show index or elapsed
time the pointer will indicate progress through the
track now playing.
ii). When the time display is set to show remaining time
or disc total time the pointer will indicate progress
through the entire disc or program (if stored).
A comprehensive display of status information is
therefore possible at all times.
Power Supplies
For peak sonic performance, the Cyrus DAD7 is equipped
with over 12 separately regulated power supplies,
ensuring maximum isolation between digital disc reading
circuitry and the sensitive analogue D/A conversion
stages.
When upgraded with the Cyrus PSX-R intelligent power
supply, the sensitive analogue sections of the circuit are
fed directly from this highly stabilised and regulated
external power source, while the internal power supply is
applied more generously to the other part of the DAD7.
This results in a much improved sonic performance of the
system.When connected to the DAD7, the PSX-R
automatically adjusts its output to suit this application. In
this case PSX-R's standby status is also controlled by the
DAD7.
An 8-times oversampling 20-bit digital filter gives the
DAD7 the ability to push the sampling frequency and its
side bands well away from the audio band, while
achieving linear phase response to within 1/2 of a degree
at 20KHz. Two separate 18-bit resolution Digital to
Analogue converters with very high speed Op-Amps are
then used to convert the digital data stream to analogue
signal. This is then followed by a high performance post-
filter circuit and a low noise output buffer to drive the
signal to the output sockets.
