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.
