SETUP
This Web interface page is not as imposing as its name sug-
gests, as SOFIA 568 setup is accomplished by entries on a
number of the Web interface pages. The specific items on the
Setup
page are discussed in order here.
Radio Settings
U.S. and Canadian stations broadcasting HD Radio (the majority
of SOFIA 568 users) utilize 75-microsecond complementary
pre- and de-emphasis in FM broadcasting. Thus
75µs
is the de-
fault
De-Emphasis:
setting. This may be manually changed here
to
50µs
, the standard for Europe and some other regions out-
side North America, or to
None
as might be required for test
purposes. A proper setting is recommended, as the wrong one
will distort the tonal balance of FM reception.
Stereo
is the obvious default setting of the
Stereo/Mono:
selec-
tor, although there may be justification for a
Blend
or even a
Mono
setting to reduce annoying noise for reception of FM
broadcasts under low-signal or multipath conditions. The
Blend
function automatically narrows the stereo image as the incom-
ing RF signal degrades.
RDS/RBDS:
sets the mode for RadioData between the North
American
RBDS
or the European
RDS
standards. Although the
two standards have become more-or-less ‘harmonized’ over the
years, certain RDS features do still differ and will not behave
appropriately with the wrong setting here. Again the default
setting is for North America.
Audio Outputs
The levels for SOFIA 568 audio outputs are individually adjust-
able. Please note the associated comments relating to what
these levels actually mean.
The
Analog Level (dBu):
slider sets the rear-panel XLR balanced
left and right analog outputs to any dBu value between –15dBu
and +15dBu. dB
u
signifies the
unloaded
, balanced level from
these outputs, which have a source impedance of 200 ohms.
This means that a 600-ohm
