The ‘Basic’ Set-up Menus
1 – General Settings:
Max Volume: This 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
rst switched on. The system comes on at the ‘Max On 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 speci 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.
OSD Mode: Controls how the on-screen display is viewed.
n
MIXED: the OSD will appear on top of the existing video picture
n
FULL PAGE: 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.
Video Status: The video status control is intended for use with SCART connections, but may nd
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
fl
fm
on the rear panel and is used to inform the
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, S-VIDEO, RGB and SCRN CTRL.
COMPOSITE: This mode is used to indicate to your TV that composite video is being sent. It uses
the trigger labelled 1/RGB
fl
(which should be connected to the RGB SCART input on your TV),
as shown. Select this option if you are using the composite video output of the AVR250.
The 2/S-VIDEO trigger is not active in this mode.
S-VIDEO: This mode is used to
indicate to your TV that S-video is
being sent. It uses the trigger labelled
2/S-VIDEO
fm
, as shown. Select this
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 1/RGB trigger is not active in this
mode.
RGB: This mode is used to indicate to
your TV that RGB video is being sent.
It uses the trigger labelled 1/RGB, as
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 2/S-VIDEO trigger is not active in
this mode.
SCRN CTRL: The two video triggers on
the rear panel have the same signal
for all outputs. This will be +12V
when any video source is selected,
otherwise 0V. This can be used (for
example) to unfurl projector screens
automatically when a video source is
selected.
