Input Config.
The audio and video settings on this page of the Setup
menu can be tailored specifically and independently for
the currently selected input.
When a different input is selected on the Input line, all the
input-specific settings for that input are displayed below it.
These settings are applied to the named Input only and are
stored in memory and recalled each time the unit is powered
up and whenever that input is selected.
Input – The currently selected input connectors to which the
settings below relate.
Name – The display name of the input. You can change
the name of any input to more closely match your setup.
For example, if you had two satellite receivers, you could
connect the main receiver to the SAT audio and video input
connectors and change the Name to 'SAT 1' . You could then
connect the second satellite receiver to the UHD audio and
video input connectors, but change the UHD Name to 'SAT 2' .
It is then clearer to users of your Receiver which inputs they
wish to select when scrolling though.
Lip Sync – Each input can have its own setting to add a time
delay between the audio and video signals to compensate
for the sound and picture not being synchronised. This
is normally required when video processing is used in the
system for scaling or de-interlacing video. The range of lip
sync delay is 0 to 250 milliseconds.
The lip sync adjustment can only correct for delayed video. If
the audio is late set lip sync to its minimum.
Mode – Sets the initial audio decode mode for stereo sources
on this input.
Last Mode recalls the last used setting for this input when
a stereo source was applied. See section "Two-channel
source modes" on page EN-35 for more information.
MCH. Mode – Sets the initial audio decode mode for
multi-channel digital sources on this input.
Last Mode recalls the last used setting for this input when
a stereo source was applied. See section "Multi-channel
source modes" on page EN-35 for more information.
Bass –
Treble –
These allow you to alter the bass and treble tone controls
for all currently active speakers for each individual input. For
example, if your PVR source sounds a little bass light, you
can always correct for this by selecting PVR on the Input
line at the top of this menu and add 2 or 3dB to the Bass
control. Then, whenever the PVR input is selected, the bass
is automatically boosted for as long as that input is selected.
Room EQ – When the Dirac Live Bass Management
application is run and EQ filters are downloaded into one of
the three slots available, this can be selected.
Not Calculated: (Information only) There are no EQ filters,
so cannot be selected.
Project Name: Dirac Live Room EQ is applied to the
current source and will display the name of the project
from the Dirac Live application.
Off: Dirac Live Room EQ is not applied to the current
source.
Input Trim – Sets the maximum analog input signal level
(sensitivity) on this input before the ADC (Analogue-to-
Digital converter) signal path clips. Options are 1, 2 and
4 volts RMS maximum input. The default is 2Vrms maximum.
For example, analog sources with low output levels may
benefit by choosing the 1V maximum setting. This helps
maximize signal-to-noise performance of the Receiver and
also helps keep the various analog sources sounding about
the same level for any given Receiver volume control setting.
Dolby Volume – Dolby Volume is an intelligent system
that improves the perceived audio frequency response
at lower listening levels and corrects for volume
inconsistencies between sources (e.g. a rock radio station
and a BD) and between programming (e.g. a TV show and
advertisement breaks).
On: Dolby Volume is applied to this input.
Off: (default) Dolby Volume is not applied to this input.
Dolby Leveller – This setting of Dolby Volume controls
how closely quiet and loud sources and program content
are matched to each other, based on the ear's perception
of loudness. The range of values is 0 (minimal levelling) to
10 (maximum levelling). The default setting is 2, however
we recommend experimenting with higher values if your
source material is less closely matched in level. If the Volume
Leveller function is set off, no level matching between
sources and program material is performed. Note however
that turning the Dolby Leveller setting of Dolby Volume to
'Off' is not the same as turning the entire function of Dolby
Volume to 'Off' , as volume related frequency response
processing is still active.
DV Calib. Offset – The Calibration Offset parameter of Dolby
Volume allows you to compensate for speaker efficiencies
and listening position. The default value is 0 and this should
normally produce a good result when the Receiver speaker
levels are set using a sound pressure level meter.
Stereo Mode – If you have configured your system to have
a subwoofer, then you have the flexibility to choose how
bass information is distributed between the front left/right
speakers and the subwoofer when listening to stereo (two
channel only) analog and digital sources. Choose the option
which gives you the most solid, even sounding bass. If you
are using a subwoofer for stereo, please also see Sub Stereo
below to set the level of the subwoofer. For best results test
with a setup disc unless Dirac EQ is active on the input. This
setting can be used to override your normal speaker settings
in the Spkr Types menu whenever the Receiver plays stereo
material. It is quite common to some people find that two
channel stereo music listening is best done with a slightly
different sub/speaker setting than for surround movies.
As Spkr Types: When an analog or digital stereo source
is played, your normal speaker configuration (as in Spkr
Types menu) is used to reproduce the signal.
EN-31
Left/Right: This setting provides a full-range 2-channel
signal. All audio is sent to the front left and right speakers
only without any bass redirection. You can use this setting
if you consider your front left/right speakers to be able to
handle the full frequency range of music. If you have set
your front left/right speaker size as Small in the Spkr Types
setup page, you may wish to use this option to override
the setting to Large for stereo music listening, if you have
full frequency range left/right speakers. It can often be
beneficial to set full frequency range speakers to Small in
the Spkr Types setup page for use with movies, if you have
a subwoofer in your system. Doing so may deliver more
impact on movie soundtracks as subwoofers are designed
to handle reproduction of high bass content. However
some listeners may find that for stereo music a better
overall result is obtained by not using the subwoofer and
effectively treating the front left/right speakers as Large.
Left/Right+Sub: Full frequency range stereo is fed to the
front left and right speakers and extracted bass is sent to
the subwoofer. In this case the low frequency information
is effectively duplicated which may result in unpredictable
and colored low frequency reproduction. This setting is
not recommended for accurate sonic reproduction.
Sat+Sub: Use this setting if you really do have Small
satellite front left and right speakers, or if you prefer the
overall sound of bass being handled by the subwoofer.
Full bass management is used so that analog and digital
stereo sources are fed to the DSP where the bass is filtered
off front left and right and redirected to the subwoofer.
NOTE: The Stereo Mode function is not available when
using an analog source in Stereo Direct mode.
Sub Stereo – If Left/Right+Sub or Sat+Sub is selected in
Stereo Mode above, this setting adjusts the level of the
subwoofer when the source is two channel stereo.
IMAX Mode – Selects if IMAX mode is enabled from the
incoming audio stream (auto) or forced on or off.
Auro-matic 3D – Selects the mode of the Auro-matic 3D
upmixer.
