2- Connecting
All connections should be made with your amplifier, and ideally the rest of your equipments, switch off.
The choice of a speaker cable is quite an important parameter to get a well balanced system.
Try to keep it as short as possible.
Ask your AperturA dealer for advice when choosing cable.
Check to insure the correct polarity between your amplifier and speakers.
The speakers’ terminals accept banana & spade plugs. We recommend the use of banana plugs.
Important
: In the EEC the use of banana plugs is considered a potential safety hazard. Such plugs may be
inserted into the holes of un-shuttered main supply sockets.
You should ensure that banana plugs cannot be used in an unsafe manner by children or other uninformed
persons.
3-Break-in period
Your speakers have an initial break-in period before reaching their full performances.
During this break-in period some electro-mechanical parameters (dielectric, suspensions, insulator…) will
change subtly and may undergo several gradual shifts of speaker performances, until full potential is
reached.
The time taken for the loudspeakers to achieve their intended performances will be around 200-300 hours.
4- Positioning
Important: When handling your loudspeakers do not touch the drive units and avoid contact with any
tool or other article.
4.1- Speaker placement
The distance between the two speakers should be no less than 2m.
The listening position should form an equilateral triangle with the two speakers.
Adjusting the toe-in angle of the speakers is useful in fine tuning according to your personal
taste and your listening room configuration.
When the speakers are facing straight forward, they tend to create a larger sound stage, to the
prejudice of the image. When rotated towards the listening position, the image becomes more
compact and coherent.
If the listening position is closed to the speaker (e.g. 2.5m), you may try to angled slightly the
speaker on the back. The easiest is to raise the front spikes and lower the back spikes.
