Arcam AV860 Manuel page 32

Incoming Sample Rate – (Information only) The
sample rate of the digital audio stream connected to this
input, if present.
Incoming Bit Rate – (Information only) The bit rate
of the digital audio stream connected to this input, if
present.
Dialnorm – (Information only) If a Dolby Digital audio
stream is connected to this input, this is the Dialogue
Normalisation setting requested by the stream.
Video Input – The currently selected video input. For
inputs that have video connections (e.g. SAT, PVR etc),
audio and video inputs normally switch over together.
However, here you can temporarily select a different
video source for the current audio source. This feature
may be useful, for example, if you are watching a sports
game on satellite but on this occasion wish to listen to
the commentary on the radio instead. This temporary
override is reset when the input source is changed so
that the Video Input follows the Audio Input setting (or
the setting in the Video Inputs menu, if applicable).
Incoming Resolution – (Information only) Shows the
incoming video resolution.
Audio Compression – Allows selection of compression
which is ideal for late night listening. The compression
effect increases the volume of the quiet passages
and decreases the volume of the louder passages.
Compression only applies to Dolby / DTS soundtrack
formats that support this function.
<
Off: (default) no audio compression is applied.
< Medium: compression is applied so that loud
portions of a soundtrack are reduced in level. Dolby
True HD stream is compressed automatically as set
by the incoming stream.
<
High: the maximum amount of dynamic range
compression is applied, so that the difference
between loud and quiet portions of a soundtrack is
minimised.
This setting applies to all inputs when a relevant digital
audio stream is detected. It is stored in memory and
recalled each time the unit is powered up.
Balance – To alter the sound balance temporarily
between front left and right speakers. You can alter
the sound stage to either the left or the right by up to
6dB. Note that it is not possible to shift the audio signal
completely over to one channel. This function resets to
equal left/right balance when the input is changed.
Dolby Centre Spread – Allows adjustment of the sound
field for Dolby Surround mode decoding of two-channel
sources.
<
Dolby Centre Spread: Controls the centre image
width.With Dolby Surround decoding, dominant
centre signals come only from the centre speaker. If
no centre speaker is present, the decoder splits the
centre signal equally to the left and right speakers
to create a 'phantom' centre image. The Centre
Spread control allows variable adjustment of the
centre image so it may be heard only from the
centre speaker; only from the left/right speakers as a
phantom image; or from all three front speakers to
varying degrees.
Digital Output Freq. – Sets the sampling frequency of
the audio Analogue-to-Digital converter. This setting
applies to all inputs when analogue audio is being
processed (i.e. not Stereo Direct mode). It is stored in
memory and recalled each time the unit is powered up.
Maximum Volume – Limits the maximum volume
setting the system can be turned up to in the main zone.
This is a useful feature to prevent accidental overdriving
of low power-handling speakers (for example). It is
stored in memory and recalled each time the unit is
powered up.
Max On Volume – Limits the maximum volume the
system operates in the main zone when it is switched
on or comes out of Standby. The system comes on at
this stored volume setting if the last used (possibly very
loud) volume exceeds this value. It is stored in memory
and recalled each time the unit is powered up.
Display on time – Sets the time that the front panel
display remains illuminated after receiving a command.
The default is always on.
CEC Control (Ouput 1 only) – Enables or disables HDMI
CEC control, a system that allows devices connected
with HDMI to control other compatible connected
devices.
<
Off: disables CEC Control
<
Output 1
ARC Control (Output 1 only) – Enables or disables the
HDMI Audio Return Channel. This allows for television
sound to be sent back to the Receiver, via the 'Display'
input. ARC Control depends on CEC control being set.
HDMI Audio To TV – Enables or disables the
transmission of HDMI audio from the HDMI output
connector. Enable this setting if you wish to be able to
listen using your TV speakers.
Control – Enables or disables RS232 or IP (NET)
control, a system that allows control from various third-
party home automation systems. Note, only RS232 or IP
control can be used, not both.
Power on – Determines how the unit powers on.
<
Stby: in Standby mode
<
On: On
<
Last state: Last state (default).
Standby Mode – Determines what functionality is
retained while in standby.
< Low Power: Lowest power setting
< IP & HDMI ON: Allows for IP control & HDMI
bypass while in standby, but consumes more power.
Language – Select the language for the OSD menu
- English, French, German, Spanish, Dutch, Russian,
Chinese.
Speaker Types
Settings for the types of loudspeaker you have connected
in your configuration. These settings are applied to all
audio inputs and are stored in memory and recalled
each time the unit is powered up.
Front Left/Right –
Centre –
Surr. Left/Right –
Surr. Back L/R –
Height 1 –
Height 2 –
Subwoofer –
Here you set the type of speakers that you have
connected to your Receiver:
<
Large: capable of full frequency range reproduction
<
Small: not capable of full frequency range
reproduction at the low frequency end
<
None: speaker not present in your configuration
<
Height 1, 2: configures the type of height speakers -
height/Dobly enabled.
< Subwoofer: Sets whether you have none, 1 or 2
subwoofer(s) present.
NOTE
It is not possible to set all speakers to Small unless
there is a subwoofer in your speaker configuration.
If you do not have a subwoofer, you will be forced to
set your front speakers to Large.
E-30
Crossover Freq – This is the frequency at which
loudspeakers set as Small start to redirect bass signals to
the Subwoofer or Large speakers in your system. Small
speakers redirect bass to the subwoofer, if present.
Dolby Speaker Crossover– This is the frequency
at which height speakers set to small redicrect bass
information.
Use Channels 6+7 for – If your main zone speaker
set up does not include Surround Back Left and Right
speakers, you can choose to use the Surround Back
amplifier channels as the Height 1 amplifiers, to Bi-Amp
the Front Left and Right pair, or as a stereo power
amplifier for Zone 2.
Speaker Distances
Calibration settings for the distances between the
loudspeakers and the listening position.
NOTE
Speakers that are not present in your configuration
will be greyed out.
If Dirac Live for Arcam is used, these settings will
also be greyed out as they are autoset by Dirac
These settings are applied to all audio inputs and are
stored in memory and recalled each time the unit is
powered up.
Units – Select whether you wish to measure distances in
imperial or metric units.

As described in "essential setup" on page E-26, measure
the distance from each loudspeaker in your system to
your ear in the main listening position and enter the
values. This allows the Receiver to calculate the correct
relative delay for each loudspeaker.
