Operation
Based on Harman International’s years of
research into surround sound technology,
the Wrap circuits take advantage of advan-
ces developed by noted surround sound
designer Jim Fosgate. Wrap differs from
conventional surround effect controls in
that it blends carefully controlled amounts
of uncorrelated front channel signal into
the surround channel in response to fre-
quency, level and phase changes.
To use the Wrap circuits, the AVR41 must
first be placed in the Pro Logic or
Phantom mode by pressing the
Surround
button
r
until the
correct mode name appears in the front
panel display. Note that in these modes
the
Wrap Indicator
˜
on the front
panel will illuminate.
To adjust the degree of Wrap in use, press
the
Wrap
buttons
ˆo
until the
spaciousness is to your liking. The
changes in the
Wrap Indicator
provide
a visual reference of the amount of Wrap
that is applied.
Note that there is no “right” or “wrong”
setting for the Wrap circuits. Experiment
and find the setting that sounds best. For
example, you may want to increase the
wrap for a sporting event or concert
recorded in a large concert hall, while you
may wish to decrease it for intimate
chamber music presentations.
To some ears the impact of the wrap
circuit may seem subtle, and this is
normal. Remember that how audible the
wrap effect will be varies with the
acoustics of your listening room, the
system volume and the type of
programme material.
Note that the Wrap circuit is not in use
when the
Wrap Indicator
˜
displays
the two lights connected by the REF bar
only (and possibly the one on top).
When the
Wrap
buttons
ˆo
are
pressed when the AVR41 is in the
Hall
mode, the circuits are adjusting a con-
trolled amount of level into the rear
channels. The amount of this change
will be indicated in the
Information
Display
by numbers in "dB". Thus, even
in the
Hall
mode, you can optimize the
surround effect in reference to your
room, the source material and your per-
sonal favour..
Tuner Operation
The AVR41 is capable of tuning AM,
FM and FM Stereo stations. They may be
tuned manually or automatically, or
stored as a favorite station recalled from
a 30 preset memory. In addition, the
AVR41 features RDS, which enables you
to use special data transmitted by many
FM stations to identify a programme,
search for a particular programme type
or display Radiotext or the time.
Station Selection
1. Press the
AM/FM
button
6d
to
select the tuner as an input.
2. Press the
AM/FM
button
6d
again
to switch between AM and FM so that the
desired frequency band is selected.
3. Press the
Tuning Mode
button
˘
to
select manual, automatic or RDS only
(see page 18) tuning.
When the
AUTO
indicator, but not the
RDS
indicator, is illuminated the tuner
will automatically search those stations
that have a strong enough signal to be
received with acceptable quality. Stations
with a lower signal strength will be
muted if tuned manually, do NOT open
the volume too much in this case.
If the
AUTO
indicator is NOT illumin-
ated, the tuner is in a manual tuning
mode and will stop at each frequency
increment without any muting. All sta-
tions will be received in Mono mode only.
4. To select stations from the front panel
press the
Tuning
button
Ú
. When the
AUTO
indicator , but not the RDS indi-
cator, is illuminated each press will cause
the tuner to search for the next station
that has an acceptable signal. To tune to
the next station, press the button again.
