BASIC SETUP
1 – GENERAL SETTINGS:
1 - General Settings
Volume Display: Normal 0-72
Max Volume: +72
Max On Volume: +20
Delay units: Imperial
OSD Mode: Mixed
Video Status: SCART
HQ Video: RGB
Sync On Green: Off
Volume display: Allows you to select how volume is displayed.
Choose from
Normal 0–72 (in 1dB steps), THX Ref –53dB to +18dB,
and Fine 0–72 (in 0.5dB steps). We recommend setting this to THX
Ref as this represents a volume control around 0dB (the reference
level) which is the same loudness level of a movie in a movie theatre
once you have correctly calibrated your system.
Max Volume: Limits the maximum volume setting the system can be
turned up to. This is a useful feature to prevent accidental overdriving
of low power-handling speakers, for example.
Max On Volume: Limits the maximum volume the system operates
at when it is first switched on. The system comes on at this volume if
the last used (possibly very loud) volume exceeds this value.
Delay units: Controls whether the delay settings for the speakers
in surround modes are specified in terms of
Time, Imperial or
Metric distances from the listening position. Either enter the time
delay to each channel if calculating the delay in milliseconds, or select
between
Imperial or Metric measurements to calculate the time delay
automatically. Imperial is measured in feet and Metric is measured more
precisely in 0.1m (10cm) increments. Note that 1 foot is approximately
0.3 metres.
NOTE: Changing the units resets all distances/times to zero. It is
therefore important to choose the units (Time, Imperial or Metric)
before set up.
OSD Mode: Controls how the on screen display is viewed. Mixed
will overlap the OSD on top of the existing video picture, while
Full
Page will give a full screen black background with the OSD displayed
in white.
NOTE: In Mixed mode, the highlight bar is black if video is present. It
is blue if no video signal is present or if in Full Page mode.
Video Status: Can be set to Screen Ctrl or SCART. This controls the
triggers (Video Trig 1) into the display device to tell the display what
video type is being used. SCART refers to the multipole A/V connector
commonly used on European A/V equipment.
HQ Video: Allows selection of the high quality video output to match
your display device. Choose between
RGB or Component. The AV8
allows progressive scan and high definition TV (HDTV) signals to be
passed through the high quality component inputs to the high quality
output. Note that the OSD cannot overlay text at any rate other than
standard NTSC or PAL.
On video signals that have a sync rate of greater than the normal
interlaced rate (i.e., progressive scan, frame-scaled video, HDTV) the
OSD will automatically go into Full Page mode (black background) so
that the control menu can be accessed. Any pop-up displays (such as
the volume bar, source selection information, etc) will be switched off.
Sync On Green: This applies only if RGB video is used. On makes
the AV8 feed the video sync signal out with the green signal. Some
RGB-driven display devices require a sync signal on the green input
to lock on to the video signal coming in, while others need the video
synchronisation on a separate lead. Systems using SCART connections
will normally have a four-wire system (i.e., with sync on composite
[CVBS] video).
NOTE: The ‘Sync on Green’ menu option is not selectable when
‘Component’ is selected as the HQ video type.
2 – SPEAKER SIZES
The size and number of loudspeakers are defined on this page of the
OSD.
2 - Speaker Sizes
Auto Setup: Custom
Front L/R: Small
Centre: Small
Surr.L/R: Small
Surr.Back L/R: Small
Subwoofer: Present
Rears for 5.1: Both
A note on speaker sizes
A
Large speaker is one that is capable of handling a full range signal (i.e.,
20Hz–20kHz).
A
Small speaker is one that is not capable of reproducing a deep bass
signal (i.e., below 100Hz), for example a satellite speaker.
None is used when there is no speaker connected to that channel.
Auto Setup: Allows the setting of ‘standard configurations’ as in the
table below:

Custom setting allows you to choose any combination of speakers to
suit your system. Note that the centre and rear speakers cannot be set
to large if the front speakers are set to small.
THX automatically sets the speaker selections to the specified
configuration for THX
™ listening. This automatically sets the
surround back speakers to None‚ and all filters are set to 80Hz. This
configuration is not adjustable. Only select this if you are using a full set
of THX
™ certified speakers.
THX Surr.EX automatically sets the speaker selections for a THX ™
Surround EX setup with a pair of surround speakers, a pair of surround
back speakers and all filters set to 80Hz. This configuration is not
adjustable. Only select this if you are using a full set of THX
™ certified
speakers.
