Upsample
The upsample feature allows you to take
native rate sampling frequencies (such
as 44.1 and 48 kHz) and interpolate
additional samples (upsampling) to 354.8
and 384 kHz sampling frequencies.
To turn the upsampling on or off, press
the ‘MENU’ button until the display
reads ‘UPSAMPLE’. Press the ‘OPTION’
button to toggle between ‘ON’ and
‘OFF’. Press the ‘ENTER’ button to
confirm your selection, and the display
will read
‘OKAY’. Upsampling is not
applicable for DSD music files.
Filter
The DAC9 offers two different digital
filter algorithms, labeled ‘FAST’ and
‘SLOW’.
Each algorithm has its own
sound characteristics, one of which
may suit your listening preferences over
the other. The digital filter is always
active, and can not be defeated.
To select a filter algorithm, press the ‘MENU’
button on the remote until the display
reads
‘FILTER’. Pressing the option button
will toggle between ‘SLOW’ and ‘FAST’.
Press ‘ENTER’ to confirm your selection,
and the display will read ‘OKAY’.
Invert
The invert button allows the absolute phase
of the recording to be switched between
‘normal’ (in - phase) and ‘invert’ (180°
inversion).
To invert the audio signal, press the ‘MENU’
button until the display reads ‘INVERT’. Use
the ‘OPTION’ button to select between
‘ON’ (inverted signal, 180 degree phase)
and ‘OFF’ (non-inverted, 0 degree phase).
Pressing the ‘ENTER’ button confirms your
selection, and the display will read ‘OKAY’.
Display Brightness
The display brightness feature offers six
different settings (including off) for the
vacuum fluorescent display on the front
panel. When the lowest setting (off) is
selected, the display will remain on for
five seconds after any button is pushed,
after which it will revert to a black screen
with a small, illuminated square in the
center to indicate the unit is powered on.
To change the display brightness, press
the ‘MENU’ button until ‘DISPLAY
BRIGHTNESS’ appears. Press the ‘OPTION’
button. Continue to press the ‘OPTION’
button to change the display brightness to
your preference. Once you have selected
the appropriate brightness, there is no need
to press
‘ENTER’ or any further buttons.
Note
The remote control offers direct control
of the display brightness via two buttons
labeled
‘DISP UP’ and ‘DISP DN’. You
can choose to use these buttons as an
alternate to the settings menu.
