1/RGB trigger output with composite selected:

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

first 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 specified 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 AVR350 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.

<Mixed: the OSD will appear on top of the existing video picture

<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.

Note that no on-screen display is available over the HDMI connection.

Video Status: The video status control is intended for use with SCART connections, but may find use for other purposes. It is possible to use a SCART connection between the AVR350 and your television even though the AVR350 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 AVR350 which type of video connection is present between it and your TV, in order that the AVR350 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 AVR350.

The 2/S-videotrigger is not active in this mode.

S-Video: This mode is used to	Connector	Function	Voltage
