frequency output. Try to leave at least 40cm of space between each loudspeaker and the
nearest side wall.
The optimum stereo performance will be achieved when the speakers are positioned
2.5meters or more from the listener and about the same distance from one another. Turning
the speakers in very slightly towards the litener often helps to stabilize the stereo image.
(Fig. 3)
Speakers “image” best if you can just see the top face of the speaker from your listening
position.
Remember, there is no absolute right or wrong – if it sounds good, it is good.
QUICK CONNECTIONS
Please always use a good quality loudspeaker connection cable from an audio dealer. To
prevent impairment of sound quality, we recommend cables with cross-sections of at least 2.5
mm² for lengths up to 3 m and at least 4 mm² for lengths above 3 m.
Always switch off the amplifier or receiver before connecting or disconnecting loudspeaker
cables. Place the loudspeakers in their planned positions and cut the cables to the right
length. The cables for both channels should always be exactly the same length.
Strip 10 – 15 mm of insulation from the ends of the cables. Twist the ends – this is much
better than tinning them with solder – insert them in the terminals and tighten the terminal
screws firmly. (Fig. 1)
For good sound it is imperative that the cables must be connected in such a way that the
speakers are “in phase”. This means that the black negative terminals on the speakers (-)
must be connected to the negative (-) terminals on the amplifier, the red positive (+) speaker
terminals to the positive (+) amplifier terminals. To make this easier one wire of most speaker
cables is marked with a coloured strip or a ridge in the insulation.
Before switching on the system double-check all your connections and make sure that the
terminal screws are tight and that there are no short circuits caused by stray wire filaments –
this could cause serious damage to your amplifier!
BI-WIRING
Bi-wiring option has been supplied on all IBIS H series loudspeakers,
Bi-wiring involves the
use of two pairs of speaker cables between your loudspeakers and amplifier. If you wish to
bi-wire your H6 or H5 speakers, it is essential that you first unscrew all the binding posts and
remove the motel links that join them together. Store them safely for possible future use.
The driver units are now electrically separate and should be connected to the driving amplifier
with individual high quality cables.
