Connecting loudspeakers
The red and black terminals on the back of the AVR300 are used to make the connections to the 
loudspeakers. The speakers should be connected to the loudspeaker terminals, refering to the 
labels on the rear-panel.
When connecting the speaker terminals of the ampli er with the terminals on the speakers make 
sure that like polarities are matched (i.e., match “+” with “+” (usually red) and “–” with “–” 
(usually black)). Mismatching of polarities will result in a weak central sound, unclear orientation 
of the instruments and the sense of direction of the stereo being impaired.
There are two options for connecting the speaker cable to the ampli er:
Using bare wire ended leads:
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 ampli er and could damage the ampli er.
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 AVR300 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 ampli er to shut down due 
to overheating.
Zone 2 connections
The AVR300 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 AVR300 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 AVR300 
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 AVR300 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.
eq
 ZONE 2 OUT.
This is the audio output for Zone 2. Connect these to a line level input on 
your Zone 2 ampli er.
do
 ZONE 2 VIDEO OUT (Composite video connection). 
This is the video output for Zone 2. Connect to your Zone 2 video display 
using 75Ω low loss coaxial cable.
fk
 IN ZONE 2. 
This allows the AVR300 to be controlled remotely from Zone 2 via infrared 
remote control. See the panel for connection information.
