Opus²
Connecting Stereo Loudspeakers -2
The advantages of bi-wiring can be extended by tri-
wiring. Here each drive unit is separately connected to
the amplifier for the utmost fidelity. The advantages of
tri-wiring can be fully realised by optimising the type of
cable used to connect the drive units. Your Opus dealer
will be pleased to assist you to make the correct choice.
Unscrew each terminal a few turns and remove the
metal tri-link straps. Connect the cables between the
amplifier and the loudspeakers as indicated and re-
tighten all terminals securely.
Tri-Wiring - Opus 1, 2, 3
Using separate amplifiers for treble, mid and bass
units further improves performance by ensuring that
each loudspeaker is separately driven - operating each
drive unit with its individual amplifier means that each
amplifier channel sees a narrower frequency range.
This both maximises signal delivery and reduces
distortion artefacts to negligible proportions.
Although all the amplifiers on one channel need not
have the same power output, the amplifiers must be
phase coherent and have identical voltage gains. The
amplifier setup used must obviously be identical to
both channels.
You can tri-amp the loudspeakers, or use two
amplifiers with one amplifier connected to the bass
channel, and the other connected to midrange and
treble terminals in a bi-wiring configuration.

IMPORTANT!
If you are considering multi-amping, unless you know
exactly what you are doing it is essential that you
seek the advice of your Opus dealer before proceeding
further.
