The 'Basic' Set-up Menus

1 – General Settings:
Max Volume: This limits the maximum volume setting the system can be turned
Max On Volume: Limits the maximum volume the system operates at when it is
Delay units: Controls whether the delay settings for the speakers in surround
OSD Mode: Controls how the on-screen display is viewed.

(possibly very loud) volume exceeds this value.
modes are specifi ed in Imperial or Metric measurements from the listening
position, or in terms of time. Either enter the time delay to each channel if
calculating the delay in milliseconds, or select between Imperial or Metric
measurements and allow the AVR250 to calculate the time delay automatically.
Imperial is measured in feet and Metric is measured more precisely in 0.1m
(10cm) increments (1 foot is approximately 0.3 metres).
Note that changing the units resets all distances/times to zero. It is therefore
important to choose the units (Time, Imperial or Metric) before set up.

MIXED
: the OSD is displayed in white on a full screen black background.

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.
use for other purposes. It is possible to use a SCART connection between the AVR250 and your
television even though the AVR250 does not have a SCART socket; a pin-out for a SCART lead
suitable for this purpose is given on page 32. We suggest the 'SQART' cables manufactured by
QED (www.qed.co.uk); please ask your dealer for details.
This setting controls the two video triggers
AVR250 which type of video connection is present between it and your TV, in order that the
AVR250 can set the control lines correctly for SCART connections. Note that if you do not wish to
use the video triggers or a SCART connection, then it does not matter which value this item has.
This item has four settings:
COMPOSITE
This mode is used to indicate to your TV that composite video is being sent. It uses
COMPOSITE:
the trigger labelled fl (which should be connected to the RGB SCART input on your TV),
1/RGB
as shown. Select this option if you are using the composite video output of the AVR250.
The trigger is not active in this mode.
2/S-VIDEO
: This mode is used to
S-VIDEO
indicate to your TV that S-video is
being sent. It uses the trigger labelled
fm , as shown. Select this
2/S-VIDEO
option if you are using the S-video
output of the AVR250.
Note that, if this option is selected,
the connection labelled 'S-video
SCART' (or similar) must be used on
the TV, as not all SCART connectors
are wired for S-video.
The trigger is not active in this
1/RGB
mode.
: This mode is used to indicate to
RGB
your TV that RGB video is being sent.
It uses the trigger labelled
1/RGB
shown. Select this option if you are
using the RGB output of the AVR250.
If this option is selected, the
connection labelled 'RGB SCART' (or
similar) must be used on the TV, as
not all SCART connectors are wired
for RGB.
The trigger is not active in
2/S-VIDEO
this mode.
