Connecting loudspeakers

The red and black terminals on the back of the AVR250 are used to make the connections to the
loudspeakers. The speakers should be connected to the loudspeaker terminals, refering to the	The speaker connectors

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 AVR250 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.

Zone 2 connections

The AVR250 allows independent routing and control of analogue audio and composite video to a second room such as a kitchen, bedroom or lounge. This second room is known as ‘Zone 2’.

For Zone 2, the AVR250 outputs a line-level audio signal taken from the stereo analogue audio, and a composite video signal taken from the composite video input (for a given source). The analogue inputs are required because there is no analogue-to-digital, DSP processing or digital-to-analogue conversion available for Zone 2 signals. As the AVR250 does not convert video formats for Zone 2, a composite video signal must also be connected from the source.

For these reasons, we recommend that source devices that have a digital connection are also connected via the analogue inputs. High quality YUV/RGB and S-video sources should also have their composite video outputs connected to the AVR250 for use in Zone 2.

NOTE: As a composite input is required for Zone 2, it may not be possible to run your DVD player in progressive scan mode and to use Zone 2 at the same time, unless your DVD player can output both progressive scan and composite signals simutaneously.

This is the audio output for Zone 2. Connect these to a line level input on your Zone 2 amplifier.
