Limitations
Main channel vs. sub-channels (FM only):
The main channel is the only channel that
can receive in hybrid mode (both digital and
analog). If a frequency has sub-channels,
they are broadcast in digital mode only. The
main FM channel will be displayed as, for
example, "WRIF-FM HD1". The sub-FM
channels will be displayed as"WRIF-FM
will be
HD2", "WRIF-FM HD3", etc.
Reception coverage area: Due to current
IBOC transmitter power limitations, the
reception coverage area in digital mode is
somewhat more limited than the station's
analog coverage area. Be aware that, like all
radio transmission technology, terrain, time of
day, vegetation and buildings can have a
positive or negative effect on radio reception.
Analog to digital/digital to analog blend-
ing: Analog to digital blending will occur as
the signal strength reaches a preset thresh-
old in the receiver. This will be noticeable in
fringe areas (areas with weak reception) and
is normal.
AUDIO, MEDIA AND INTERNET
NOTE
There may be a noticeable difference in
sound quality when a change from analogue
to digital or digital to analogue occurs, such
as:
Volume increase or decrease
Equalizer settings, i.e., Bass/ Midrange/
Treble cut or boost
Time alignment (Digital program material
in extreme cases can be as much as 8
seconds behind the analogue). This will
noticeable as a "stuttering" effect.
The above items are dependant on the
broadcaster's equipment settings and do
not indicate a fault in the vehicle's radio
receiver or antenna systems.
