Conclusion

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 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.

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

– Open bag containing speaker
– Tape the carton flaps back
– Turnover car ton with loudspeaker still inside
– Lift carton off, leaving loudspeaker standing on the floor

– Be careful not to damage soft floor surfaces with spikes

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.

– Lift the grille carton out

– Unwrap the grilles and place them on the loudspeakers.

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.

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.
