Video connections

The AVR250 allows for conversion between different video formats. This means that the AVR250 can convert between composite, S-video and component, if required.

For example, if you are watching a composite input from a VCR, you may view it from the S-video or Component/RGB video outputs of the AVR250. This allows you to use a single (typically high-quality Component/RGB) connection between the AVR250 and your display device.

The record loops do not work from the video converter. This means that to record a S-video or composite signal, a S-video or composite signal (respectively) must be supplied.

The following video conversions are possible:

To:	Composite	S-video	Component/
From:			RGB
Composite	Yes	Yes	Yes
S-video	Yes	Yes	Yes
Component/	No	No	Yes
RGB

Note that conversion between RGB and Component video (or vice-versa) is not supported by the AVR250.

Composite/S-video video connections

dm dn MONITOR OUT.

Two video output connectors are provided, one for S-Video and one for composite video. The outputs carry the same information at all times (and both may be used simultaneously, if required). Connect one of these outputs to the video input of your display device.

dq VCR IN, ds PVR IN, dt AV, ek SAT, el DVD.

Connect the composite video outputs of your source equipment to these inputs. The choice of connection to use (S-video or composite) depends on where the signal is to be routed to: if the signal is to be used in Zone 2, then a composite connection is required; if the signal is to be used for recording (routed to a VCR, for example), then the connection type must match the connection to the recording device (i.e., if the recording device requires a S-video signal, then a S-video connection from the source equipment must be used).

If both connections are made, the signal from the S-video input will be used for the main zone if no Component/RGB signal is supplied.

dp PVR OUT.

Connect one of the S-video or composite video outputs to the video input of your VCR or PVR. The connection used must match the video type of the source you wish to record (as described above). For example: if you wish to record a S-video signal from your satellite receiver on your VCR, the connection to the VCR must also use S-video.

High quality (Component) video connections

These inputs are suitable for connection to component (YUV/YCrCb) or RGB outputs. These signals are usually available from a DVD player, set-top box or games console and offer the best possible picture quality.

SCART RGB 4-WIRE CONNECTION

(SCART refers to the multipole A/V connector used commonly on European A/V equipment.)

Some video projectors and most European TV sets require the use of a 4-wire RGB connection, where the ‘sync’ signal is separate from RGB. In this case, you need to use the composite video MONITOR OUT dn for the sync information. A cable is available from your dealer to make this 4-wire RGB connection (refer to the table of SCART connections at the back of the manual). Note that use of this feature requires (in addition to the RGB connections) a composite video connection between the source and the AVR250, in order to supply the additional synchronisation signal.

Note that most SCART TV inputs will require the SCART RGB status line to be controlled before the RGB signal will be displayed. The RGB trigger output will control this signal when connected to the SCART socket using a cable of the type given on page 32. These cables are available from your dealer.

The AVR250 does not support either 5-wire RGB HV or 3-wire RGB sync-on-green connections.
