HDMI

An HDMI connection between a source and your display device offers the best possible picture quality. This connection type is, however, the most limiting in terms of routing, advised cable length and conversion.

The AVR350 provides two HDMI inputs; these are labelled ‘DVD’ and ‘SAT’ in anticipation of the most common use for these connectors, but they may be used for any HDMI source. These inputs may be configured to be associated with any of the other sources, so that selecting that source (‘AUX’, for example), selects one of the HDMI inputs instead of the usual input associated with that source.

It is important to realise that analogue video sources cannot be routed by the AVR350 to the HDMI output, nor can either of the HDMI inputs be converted to analogue video (of any sort). The AVR350 acts simply as a switching device, selecting one of the inputs and routing it to the output.

Keeping the above in mind, it will be necessary (as with the high-quality analogue video connections), to provide a composite video feed, in addition to the HDMI connection, if the video is to be routed to Zone 2.

Connecting loudspeakers

The red and black terminals on the back of the AVR350 are used to make the connections to the
	The speaker connectors
loudspeakers. The speakers should be connected to the loudspeaker terminals, refering to the
	on the rear-panel are
labels on the rear-panel.
	labelled as follows:
When connecting the speaker terminals of the amplifier with the terminals on the speakers
	FL - Front Left
make sure that like polarities are matched (i.e., match ‘+’ with ‘+’ (usually red) and ‘–’ with ‘–’
	FR - Front Right
(usually black)). Mismatching of polarities will result in a weak central sound, unclear orientation
	CEN - Centre
of the instruments and the sense of direction of the stereo being impaired.
	RS - Right Surround
There are two options for connecting the speaker cable to the amplifier:
	LS - Left Surround
Using bare wire ended leads:	RSB - Right Surr. Back
	LSB - Left Surr. Back
1. Strip back the insulation on the wire to reveal about 2cm of conductor (the metal inside
the cable).

2.If the conductor is stranded, twist the strands together tightly to avoid loose strands making contact with the adjacent terminals or the back panel.

3.Loosen the terminal by turning it anti-clockwise

4.Insert the twisted wire through the hole in the terminal.

5.Tighten by turning clockwise.

When making connections with stranded bare ended wires, take great care that no individual strands of wire come into contact with the adjacent terminals or with the back panel. If this should happen, it will cause a short circuit on the output of the amplifier and could damage the amplifier.

Using spade terminals:

1.Loosen the terminal by turning it anti-clockwise

2.Insert the spade connector under the terminal.

3.Tighten by turning clockwise.

Speaker impedance

Before connecting loudspeakers to your AVR350 you must set the impedance switch on the rear to the correct position (never adjust this switch with the power on or you may damage your speakers). If your loudspeakers are rated at 6Ω or lower set the switch to the 4Ω position; if your loudspeakers are rated higher than 6Ω, set the switch to the 8Ω position. This unit should only be used with loudspeakers with an impedance rating above 4Ω.

Note that failure to set this switch correctly for your speakers may cause the amplifier to shut down due to overheating.
