Your IBIS loudspeakers are equipped with gold-plated binding posts with excellent electrical
contact and current specification. The posts are connected to the individual drivers,
removable metal links enable the loudspeaker to be conventionally wired with a single cable,
bi-wired or bi-amped. These techniques often bring benefits in terms of increased clarity and
definition, Replace the metal links to return to normal single wire operation, The pictures
below show the correct set-up for conventional operation (Fig. 2a), bi-wiring(Fig. 2b) and
bi-amping (Fig.2c).
WARNING
Ensure that your amplifier is switched off before you make, or break, any connections, as
damage may occur to your amplifier if shorted.
The sockets on the loudspeaker marked red(on the right side as you look at the loudspeaker
rear panel)should be connected to the red (or positive)output terminals on your amplifier,while
the sockets marked black should be connected to the black(or negative)output terminals on
your amplifier.
Use good quality cable to connect your loudspeakers to the amplifier. Ensure that the cables
from each speaker are of roughly equal length and that any surplus is gathered in a loose
hank.
Do not coil the surplus tightly.
PHASE
If the cables are not connected to each left and right speaker in the same way, i.e.black and
red reversed in one, the effect will be incorrect phasiing. This will cause the bass to disappear
and the stereo image to spread from the middle to a position outside the two speakers.
Correctly wiring the polarity of the speakers will restore the image to between the speakers
and provide proper bass. Most speaker cables have a polarizing mark, such as a raised bump
or writing on the positive wire.
LISTENING
Switch the amplifier on with the volume tured down low. Check that the bass and treble
sounds come from both speakers. If not, switch off and remake the connections.
RUNNING IN
Your IBIS loudspeakers require a little gentle use to allow their working components to settle
into their proper working routine.
Do not concerned if your new speakers sound aggressive and lacking in low-frequency
authority when you first begin to use them. Things will quickly improve. Allow between
twenty-four and forty-eight hours of use before you expect your new loudspeakers to perform
to their full capacity.
