Begin by postioning the loudspeakers about 20cm from the rear wall and gradually move
them out a little until you achieve the best balance between bass weight and definition.
Avoid placing the loudspeakers in corners because this may cause a doubling of low
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 2meters
or more from the listener and about the same distance from one another. Turning the
speakers in very slightly towards the listener often helps to stabilize the stereo image. (Fig. 1)
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
Your
IBIS
A500 series loudspeakers are equipped with gold-plated binding posts with
excellent electrical contact and current specification. 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.
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!
The driver units are now electrically separate and should be connected to the driving amplifier
with individual high quality cables.
WARNING
Ensure that your amplifier is switched off before you make, or break, any connections, as
