IMPORTANTNOTICE TO UK USERS

The power cord on your subwoofer may be supplied with a plug
incorporating a fuse, the value of which is indicated on the pin
face of the plug. Should the fuse need to be replaced, an ASTA or
BSI approved BS1362 fuse must be used of the same rating. If
the plug is cut off it must NOT be re-used. Dispose of any such
plug safely. There is a danger of electric shock if a cut-off plug is
inserted intoa mains socket.

Connecting a Mains Plug

The wires in the mains lead are coloured in accordance with the
code: Blue: NEUTRAL, Brown:
LIVE: Green/Yellow: Earth.
As these colours may not
correspond to the coloured
markings identifying the terminals
in your plug, proceed as follows:
The BLUE wire must be connected
to the terminal marked with the letter N or coloured BLUE or
BLACK. The BROWN wire must be connected to the terminal
marked with the letter L or coloured BROWN or RED. The
GREEN/YELLOW wire must be connected to the terminal marked

Quality Management

Your Opus loudspeakers have been constructed to the highest standards of quality throughout. The acoustic components and

the whole system have been manufactured to very tight tolerances of +/- 1 decibel of sound pressure level for each driver

throughout the operational range of the unit.

All drive unit components are serially numbered and test compared to golden reference originals retained in our factory quality

control department. This scrupulous attention to detail enables us to ensure not only that all Opus² loudspeakers exactly

replicate the performance characteristics of our reference test samples, it also enables us to give a extended guarantee of

identical replacement parts should they ever be required.

A certificate of conformance to the original prototype specification, confirmed by the Opus designer and engineering director is

included in this pack.

Servicing

Servicing of Opus products should only be carried out by authorised service agents. If service is required the equipment should

be returned, securely packaged, preferably using original packaging, to your dealer.

In the UK equipment may be returned to the IAG Service Centre. In the USA equipment may be returned to the Service address

shown on this page. Always telephone before returning any equipment. A note should be enclosed giving your name, address,

telephone number, and a brief description of the reason for return.

If you require Service outside the Warranty period, do not hesitate to contact your dealer.

Safely Unpacking Your Loudspeakers

Opus speakers are heavy. Take care when

removing them from their packaging. Enlist the

help of a friend if necessary

Always take care when

lifting heavy objects. Lift

the speakers out by their

sides.

Unpacking the Opus² 1,2 &3

If your floor is at all vulnerable, protect the floor surface with a cloth or towel.
Carefully remove each loudspeaker from its packing carton. Be especially careful when
removing the polythene bag. The speakers come with the plinth complete and already
fitted. The carton top says, “Open other end”. So you:
– Open the bottom
– Remove polystyrene
– Lift the grille carton out
– Open bag containing speaker
– Tape the carton flaps back
– Turn over carton with loudspeaker still inside
– Lift carton off, leaving loudspeaker standing on the floor
– Unwrap the grilles and place them on the loudspeakers.
– Be careful not to damage soft floor surfaces with spikes

Unpacking the Opus² M1, M2, AV, Tri-Centre & Tri-Surround

Lift out the polystyrene packing pieces and unpack the loudspeakers being careful not to
lift the loudspeakers out with the polythene bags. Remove the polythene bags.
The AV speakers are packed as a system with two AVS satellites and one AVC centre
loudspeaker.

Unpacking the Opus² Stands

Before proceeding, protect the floor surface with a cloth or towel. The stands are packed
facing each other. Lift each stand out from the packing and then invert it so that the
spikes are on the floor.

Unpacking the Opus² SW250,300 and 380 Subwoofers

Open the carton and remove all the top packing pieces. Lift the subwoofer out taking
care not to damage the cabinet. When lifting the unit from the carton support it from the
bottom. DO NOT attempt to lift the subwoofer out of the carton using the polythene bag.
The unit is heavy; if you cannot manage it easily, get someone to assist you.

If possible, keep the packaging in
