OPERATION
Connections
Connect the AES/EBU signal to the input and
output plugs at the rear of the SFC2.
The sampling frequency of the connected signal
will either display in
Œ
(channel A) or in
•
(
channel B), according to which channel was cho-
sen.
Two stereo signals can be connected simultane-
ously to the the two channels A and B – they
need not be in sync.
Changing Output Sampling Fre-
quency
If none of the push buttons are pressed (none of
the buttons is lit), the SFC is in input signal follow
mode: the output will always be at the same
sampling frequency as the input. If no dither is
selected, then the output will be bit equal to the
input in this mode.
To choose another output sampling frequency,
simply press the appropriate button – it will be lit
so that the status of the SFC can be confirmed
visually.
Dither
The SFC2 is able to apply shaped dither noise to
remove distortion when re-quantizing from 24bit
to 16bit or 20bit output word length (see
TECHNICAL DATA for dither specifications).
To toggle dither on/off, press the button marked
“dither” in the “dither output settings” field. The
button is lit when dither is active.
Word Length and Autoblacking
Pressing the “mode” button int the “dither out-
put settings” field will toggle through the follow-
ing modes:
-
16bit without autoblacking
-
20bit without autoblacking
-
16bit with autoblacking
-
20bit with autoblacking
The selected mode is displayed above the
“mode” button.
If auto-blacking is activated, dither will be turned
off if the input signal is digital zero for more than
256 consecutive samples. As soon as the input
signal changes, dither will be turned on again.
This ensures that breaks between programs are
still at digital zero, regardless of dither.
