Cambridge Audio 540R V3 user manual Assigning video sources, azur 540R, HDMI Pre-Emphasis, English

5. Assigning video sources

All of the 540R v3’s rear panel video inputs (S-Video/Composite, Component and HDMI) are freely assignable to the DVD, Video 1, Video 2, Tape/MD, CD/Aux and 6.1 Direct sources for maximum flexibility.

Select the ‘Input Assign’ menu. Highlight each Video input in turn and select a source to assign it to:

Input Assign Menu

S/Comp1 : 6.1Direct

S/Comp2 : DVD

Component1 : DVD

Component2 : Video1

HDMI1 : DVD

HDMI2 : Video1

Return to Menu : [OSD]

Note: The 540R v3 prevents you from setting two sources to the same video input, as this would cause problems, but doesn’t prevent you from setting the same source to different video inputs.

The 540R v3 has two HMDI (High Definition Multi-Media Interface) inputs and one HDMI output. HDMI is a fully digital audio/video system that passes the picture and audio to the screen in digital format for best possible picture quality. DVI (Digital Video Interface) is a subset of HDMI that uses different connectors and only passes digital video to the TV/Monitor (no audio). The 540R v3 is fully compatible with DVI in that simple passive DVI-HDMI adaptors are available which allow the conversion of the DVI connector to an HDMI format connector (and back again if required) for routing via the 540R v3. The 540R v3 can switch both types of signal.

The 540R v3 performs HDMI switching, not processing, it routes the HDMI signals from the source equipment to the TV/Monitor without any processing, so as far as the 540R v3 is concerned there is no setup involved other than to assign the three inputs to a desired source. The 540R v3 does not receive audio or video over the HDMI, so for surround- sound decoding etc, an audio connection must also be made from your HDMI source to the 540R v3. As with other sources this can be analog or digital audio. A digital audio SPDIF/Toslink connection is preferred and will be required if it is desired to decode surround-sound for the

HDMI sources.

HDMI Pre-Emphasis

The HDMI interface is generally specified for transmission over cable lengths up to 5m. For longer cable runs the 540R v3 is able to apply some pre-emphasis to the HDMI signals to allow for cable losses in such situations. For cable runs <5m HDMI Pre Emphasis should be ‘Off’. For runs >5m HDMI Pre Emphasis should be ‘On’.

The maximum cable length possible depends on cable quality and to some extent on the resolution of the video being transmitted (i.e. higher bit rate signals are harder to transmit over long distances). HDMI cable repeaters are available from acessory suppliers and may be required for cable lengths >15m.

Select the ‘Output Setup’ menu, highlight ‘HDMI PRE’ and select either ‘Off’ or ‘On’:

HDMI PRE	:	On
