LOUDSPEAKER PREPARATION
opus
OPUS 1, 2 & 3 SPIKES
Your f oor standing Opus speakers are de ivered with the p inth and spikes a ready
fitted. Leve ing/seating the speaker is best achieved by adjusting either of the rear
spikes unti the speaker is stab e without rocking. Re ease the top knob, on the
underside. Turn spike out and down to eve . Re- ock top knob.
For wood or soft f oors 8 meta spike seats and se f-adhesive pads are provided for
use as required. A set of extra ong spikes for deep carpets are provided and may be
used as required.
WARNING: Opus speakers are heavy and the spikes can penetrate softer f oors
materia s over extended periods.
CONNECTIONS AND TERMINALS
Choosing and Preparing Cables
Specia ist audio cab e usua y offers better performance than genera purpose
‘be ’ or ‘zip’ wire.
Choose a cab e of suitab e diameter – cab e that is too thin wi imit the
dynamics of the sound and may impair the bass response. Audio cab e is
po arised, with two cores of different co ours, or often a raised rib of co oured
tracer in the case of twin cab e.
Sp it the twin cores to a depth of about 40mm. Carefu y strip the insu ation
from each end, eaving about 10mm of bare wire. If the cab e is stranded,
ight y twist to gather any oose strands.
Crossover Networks
OPUS front and centre oudspeakers use a specia y designed bi-wireab e
crossover pane with six termina binding posts. P ease fo ow the drawing care-
fu y to see the correct orientation of the oudspeaker termina s. The upper ter-
mina s connect to the treb e unit, the midd e pair to the mid-range and the
ower pair to the bass units. As supp ied, the treb e termina pair is connected
to the mid-range pair and bass termina pair via removab e meta straps.
These shou d be eft in p ace for standard sing e cab e insta ations.
The OPUS surround uses a conventiona twin termina crossover pane .
Connecting Loudspeaker Terminals
Unscrew the termina . Thread the bored end of each cab e through the ho e in
the bottom of the termina post. Ensure that there are no oose strands which
may touch adjacent termina s. Retighten the termina secure y.
NOTE: When connecting oudspeakers, the cab es to eft and right channe s
shou d be of equa ength, regard ess of the distance of the speakers from the
amp ifier. This app ies to front and rear channe s.

If the loudspeakers are placed too close to the walls the bass will increase but may be
boomy and indistinct. If the loudspeakers are placed further away from the walls, the
inward angle may be increased by upto 0%, although this may restrict the width of the
optimum listening position. As personal taste plays a large role, experiment with different
configurations and play a wide range of programme before finalising the position of your
speakers.
Positioning the speakers. P ace the speakers so
that you are the same distance from each. The
distance between the speakers shou d be the
same as between you and the speakers.
For best resu ts the speakers shou d be at best
10 inches (20cm) in front of a wa and at east
30 inches (70cm) from any corner.

CONNECTING HIFI SPEAKERS
Sing e wired a sing e amp ifier, tri- ink bar is fitted
Tri or Bi-wired – a sing e amp ifier, with separate wires
to drive the bass/mid unit and the treb e unit.
Additiona inks are supp ied to a ow Bi-wiring.
Tri or Bi-amp ified – two or three amp ifiers. One drives
each section or 2 sections with Bi-wire ink e.g mid/hf.
(Remove a ink sections when Tri-Amping)
Important Note, p ease make sure that heavy mu ti-standard
cab es are we connected and c amped. Sing e oose strands
arcing can cause noise in the woofers ike a fau ty speaker.
opus
Using separate cables for
treble, mid and bass units in
Tri or Bi-wiring configuration
reduces intermodulation
effects and improves
headroom and clarity. To
Bi-wire, you will need to install
two lengths of twin core cable
between the amplifier and
each loudspeaker.
Unscrew each terminal a few
turns and remove the metal
tri-link straps. Use the
bi-link straps (supplied in
accessories) to connect the
treble and mid-range
terminals. Connect the cables
between the amplifier and the
loudspeakers as indicated and
re-tighten all the terminals
securely.
Note: Some amplifiers have
two pairs of output terminals
to facilitate bi-wiring but this is
not essential. The advantages
of bi-wiring are fully retained if
your amplifier has only one
pair of output terminals per
channel (as in the illustration).
