Front panel controls
On / Off switch.
The green LED glows when the unit is switched on and
ready to use.
Note:
If the SACD 1245 R is connected to a pre-amplifier,
integrated amplifier or receiver within an 'R' system, it
can be switched off, with the whole system, by pressing
the
button on the remote control handset.
Note:
The mains button is not an isolation switch. Some parts
of the circuit are still live when the unit is switched off.
CD Drawer
The drawer of the SACD 1245 R consists of a
combination of a special plastic with good damping
qualities,
and
solid,
precision-machined
treated
aluminium. It’s floating and flexible suspension system
eliminates the transfer of mechanical vibration to the disc,
which can have an adverse effect on the sound.
Button for opening and closing the drawer.
With this button, the bandwidth of the analogue output
filter for SACD playback can be switched between
60 kHz (normal mode) or 100 kHz ('WIDE' mode).
A security switch at the back panel of the SACD 1245 R
must be set to the 'WIDE ENABLE' to allow the wide
bandwidth position to be chosen. 'WIDE' mode cannot be
chosen without the security switch set to 'WIDE ENABLE'
(also see: chapter 'Back Panel Connections').
Note:
The position 'WIDE' should only be used in combination
with amplifiers that are capable of reproducing audio
frequencies up to or beyond 400 kHz. If in doubt, please
consult the manual of your amplifier or ask the
manufacturer.
In combination with all
amplifiers the 'WIDE' position
can be used without limitation.
This button switches the phase of the signal from normal
to inverse phase and back.
The human ear is certainly capable of detecting absolute
phase when listening to particular instruments and
voices.
However, absolute phase is not always correct on
commercial recordings, and in this case you can invert it
(i. e. turn it through 180°) by pressing this button.
The correction occurs at the digital level and therefore
has no effect at all on sound quality.
Note:
The symbol
on the screen glows continuously when
INVERSE mode is switched on.
Selection of the oversampling method.
Repeatedly pressing this button cyclically steps through
the various oversampling algorithms offered by the
SACD 1245 R.
For SACD and CD playback each have two different sets
of oversampling algorithms. These special algorithms
implemented in the SACD 1245 R are optimised for each
data format.
A detailed description of the oversampling algorithms can
be
found
in
chapter
'Technical
Description
Oversampling'.
Selects the audio playback mode
• When the disc is stopped this button chooses between
the CD or SACD layer of hybrid SACDs.
• During playback of SACDs with stereo and
multichannel areas this button toggles between stereo
or multichannel playback.
Switches cyclically through the different repeat functions
of the SACD 1245 R (see chapter 'Operating the
SACD 1245 R').
