RDS/RBDS:
sets the mode for RadioData to the North American
RBDS
or the European
RDS
standard. The default setting is
RBDS (North America) .
Mod Response: refers to signal integration for the quasi-peak
readout of FM peak carrier modulation. An FCC specification
for this measurement no longer exists, but it is our recommen-
dation to err (if necessary) on the side of caution and choose
the fastest,
50µs
setting.
The Baseband Filter restricts demodulated-FM components be-
yond the 100kHz limit of the composite/MPX passband. This is
especially important in ensuring accurate FM total-mod read-
ings in the presence of the HD Radio digital signal, which is
transmitted independently of the FM-deviated carrier, but can
still interfere with analog measurements. Filter choices refer to
the HD Radio transmission mode; Auto is our recommended
choice.
Loudness Window (Sec)
settings refer to the long-term-integrated
LU loudness measurement readings for all LU-loudness meter-
ing, which is the light-blue bar on these meters. The range is
adjustable by the slider between 30 and 120 seconds. The
BS.1770 Standard is a bit nebulous with regard to this integra-
tion; we recommend the default value of 120 seconds.
MPX Output
The rear-panel
MPX OUT
BNC connector can deliver either the
FM-baseband MPX signal or the 19kHz stereo Pilot tone as se-
lected here. The
Level (V
PP
):
of the waveform may be adjusted
between
1
and
6
volts peak-to-peak in 10mV increments.
Assignable
Program Outputs
The analog left/right and AES-digital ‘assignable’ line outputs
are independently programmed and adjusted for output levels
here, both in the same manner.
The choice in each case is audio from FM , from HD1 , or from
any of four HD programs selected on the
Now Playing
Webpage
as described on Page 21. ‘Split Mode’
FM/HD1
audio is another
choice for time-alignment confirmation by ear. Selected chan-
nels will show up here as HD2 , HD3 , etc., or as HD
C
(for example)
if that selection has been set to
None
.
You may set the Assignable Analog Output Level (dBu): slider any-
where between
–15
and
+15
, and the
Assignable Digital Output Lev-
el (dB
FS
)
:
slider between
–30
and
0
. Other information regarding
these outputs is found on Page 11.
Dante/AoIP
Streams
This section of the Setup Webpage adjusts only the program
line levels of the five simultaneous Dante/AoIP output streams
on the rear-panel RJ45
AoIP Port
. As with other digital outputs,
the
Level (dBFS):
may be set between
–30
and
0
. Other Dante
settings are addressed in a separate subsection shortly.
Other
Streaming
Options
The 552 offers HTTP/Icecast Streams for general ‘tune-in’ lis-
tening, and as independent UDP streams that allow the 552 to
send raw compressed audio to a specific IP address and port.
