5.2.2
Professional Use
Digital i n p u t
(AES/EBU)
All
bits
are
copied
from the input
to
the
output, except:
a
b i t 0 :
Professional
use
always
fixed to “ 1 ”
a
b i t 5 :
Source sampling frequency:
“ 1 ” if synchronisation is not
successful. In other cases
“ 0 ”
(=
default)
a
bit 6-7:
Sampling
frequency
as the output sampling-frequency
chosen.
Analog
i n p u t
If
the analog input is selected,
the
following
default values
are set:
m
bit0:
Professional use: “ 1 ”
bit 1: | Audio -
Linear
PCM - samples: “ 0 ”
bit
2-4: Audio signal emphasis:
“100”
No emphasis
bit
5:
Source sampling frequency “ 1 ” if synchronisation is
n o t
successful. In
other
cases
‘ 0 ”
(=
default)
=
bit 6-7: Sampling frequency as the chosen output sampling frequency
The
rest
of the bits
will
be all
zeros
which
means undefined.
Note:
1. A
CRC (Cyclic redundancy
Checksum)
is always done over
the first 23
bytes
(byte
0-22)
and the
CRC
- character is
p u t
in
byte
23.
2.
The
treatment of
Bit-5
warrants
special
attention,
since
n o t
all audio
equipment complies
with the IEC
958. To
summarize the
Sound
Enchancer w i l l
s e t
Bit-5
to “ 0 ” in case of
external
synchronization. In
case
synchronization is
n o t
successful
the
value
of Bit-5
will
be set to
“ 1 ” ,
The
default setting of Bit-5 is “ 0 ”
also
if synchtonization is
n o t
applicable.
3.
Also
the
treatment of
Bit-2 in SPDIF (“copy protect”) warrants extra
attention. Bit-2 is always
s e t
to
“ 1 ” ,
which
means: c o p y
permitted.

therefore
Great
care
was
taken
to
provide
practical
and reliable subcode
han
‑
dling.
Because the quality of
the
various
digital
recorders
a n d sources
in the world is unknown, the manufacturers of the Sound
Enhancer
cannot
guarantee s m o o t h
operation
in
a l l situations.
In the
event
that a recorder is n o t designed to
handle the
appropriate
subcodes
of the digital sources available, problems
m a y
arise.
If only
one
music
track
is recorded
usually
no
problems
will
occur.
If
more
tracks
are
recorded
a n d
the time a n d track increment information is

properly
processed malfunctioning of
the recorder
m a y occur.
