General Setup - Arcam AV860 Manuel

Input Config.
The audio and video settings on this page of the Setup
menu can be tailored specifically and independently to
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
VCR audio and video input connectors, but change the
VCR 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 E-32 for more
information.
Ext. 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 E-32 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 Auto Speaker Setup function is
run it also calculates Room Equalisation coefficients to
remove some of the worst effects of resonant frequencies
of the room at the listening position. By default Room
EQ is not applied to any of the source inputs, however
you can enable them on a per-input basis as you wish.
<
Not Calculated: (Information only) Auto Speaker
Setup has not been run or has errors so cannot be
selected.
<
Project Name: Dirac Live for Arcam Room EQ is
applied to the current source and will display the
name of the project from the Dirac Live application.
<
Off: Dirac Live for Arcam Room EQ is not applied
to the current source.
Input Trim – Sets the maximum analogue 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, analogue sources with low output levels
may benefit by choosing the 1V maximum setting.
This helps maximise signal-to-noise performance of
the Receiver and also helps keep the various analogue
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 programme
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 programme 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. See "Dolby volume"
on page E-34 for more information.
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.
See "Dolby volume" on page E-34 for further
information on Calibration Offset.
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) analogue 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
or live programme material. 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 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 analogue or digital stereo
source is played, your normal speaker configuration
(as in Spkr Types menu) is used to reproduce the
signal.
<
Left/Right: Full frequency stereo information. 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
you may find that for stereo music a better overall
E-29
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.
<
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
analogue 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 analogue 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.
Audio Source – Selects the particular connection type
for each input. The default is HDMI; this setting must be
changed if another connection is used.
Select from the list the audio type you are using on this
source.
<
HDMI: the unit is forced to use the HDMI audio
input for this source.
<
Digital: the unit is forced to use the optical
( ) or coaxial ( ) digital audio input for
TOSLINK S/PDIF
this source
< Analogue: the unit is forced to use the analogue
audio input for this source.
CD Direct – Turns off the compressed audio detection
mute delay and should only be used for sources that will
only transmit PCM audio (e.g. a CD player).
