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 22. ‘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 Page12.
Dedicated
Outputs
Defined
‘Dedicated’ outputs refer to the FM, HD1 and the selected HD
A
,
HD
B
and HD
C
program channels that are available simultane-
ously. Selection is explained on Page 22. These outputs are
available, again, simultaneously, as left/right analog, AES3-
digital, and as streaming channels in Dante/AoIP, HTTP/Icecast
and UDP streams. Each is set-up under its own heading; click
the to the left of a
Dedicated Output
category to access its con-
trols.
Dedicated
Analog
The five slider controls here set the analog dBu output level for
each of the five listed program channels.
Level (dBu):
for each
program is variable between
–15
and
+15
. These outputs ap-
pear on the 551 rear panel as the five grouped RJ45 jacks la-
beled
ANALOG OUTPUTS
, characteristics of which were ex-
plained on Page 12.
Dedicated
Digital
Five simultaneous
AES3 DIGITAL OUTPUTS
appear as rear-panel
RJ45 jacks, and each may be adjusted in
Level (dBFS):
between
–30
and
0
. See Page 11 for connection details.
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.
