Conversely, if you rarely see the green LED illuminate during loud passages,
you should increase the Input Level to compensate for the relatively low
level of the source. Press the input level button, followed by the volume +
button to increase the input level.
15 SURROUND MODE SELECTOR
Pressing this button cycles among the various surround modes of the PAV:
THX cinema — for movies which were mixed for theatrical re-
lease; both THX cinema and pro logic indicators are lit, confirm-
ing that Pro Logic is in use whenever the THX cinema mode is
selected.
pro logic — for all other surround-encoded material, such as
many TV shows and some music recordings; only the pro logic
indicator is lit.
stereo surround — for enjoying two-channel stereo recordings
using all loudspeakers; the stereo surround indicator is lit.
mono surround — for monophonic recordings which would ben-
efit from some degree of additional ambience or spaciousness,
such as many classic movies and some sporting events; the mono
surround
indicator is lit.
surround off — to return the system to two-channel stereo; the
surround off indicator is lit.
mono —a “true” mono, reproduced only through the center chan-
nel speaker and subwoofer. Noisy mono soundtracks often enjoy
significant noise reduction by being reproduced in this mode;
both mono and off indicators are lit to denote the fact that the
surround circuitry is disengaged, leaving you with a “true” mono.
16 PATH SELECTOR
Pressing this button cycles among your various signal path options:
main — the home theater; this path determines which video and
audio sources are sent to the Main outputs on the back of the
PAV. Sources selected for the main path are indicated in yellow on
the front panel LEDs. (If the LED blinks red, it is indicating a
tape loop condition caused by the same source having been se-
lected on the record path; deselect the source on the record path
first, then reselect your main source.)
remote — determines which video and audio sources are sent to
the Remote outputs on the back of the PAV, to be sent to another
system elsewhere in the house. These sources are indicated in
green on the front panel LEDs. The remote path may also be
used as a secondary Record Output path if necessary.
both — the audio and video signals for both main and remote
paths may be selected at the same time, for your convenience; as
when entertaining, perhaps, for whole-house background music.
Sources selected for “both” main and remote paths will be indi-
cated by yellow LEDs (the same as for the main signal path).
record — determines which video and audio sources are sent to
the various record output jacks. The source selected for the
record path is indicated on the front panel in red LEDs. As a
safety measure, the PAV will prevent the selection of any record-
able device as its own source (to avoid feedback loops). If such a
selection is attempted, the PAV will cause the appropriate LED to
