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

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.

POSITIONING FRONT SPEAKERS

Ang e speakers inward by 5º to 30º for a

c earer, more tunefu mid range.

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).
