Heco AURORA 1000 Mode D'emploi page 8

Dear HECO Customer,
Congratulations on your fine new loudspeakers and thank you very much for choosing HECO! You
have made an excellent choice. The high-quality speakers produced by HECO are renowned all over
the world.
Please study the instructions and information below carefully before using your new loudspeakers.
FITTING THE FEET (AURORA 1000 AND 700 ONLY)
The 2 feet included in the delivery package must be fitted to the loudspeaker before use. To do this,
place the speakers on a clean, stable base with the bottom facing upwards. It is better not to remove
the protective bag until after fitting has been completed so as to avoid damage to the paint surface.
First fit the four metal spikes to the two traverses, as shown in Fig. 1: Two spikes each (x) are
screwed into the threaded holes in the traverses (w) from below as far as they will go. From above,
the lock screw (z) is then fitted and tightened.
Now fit the two pre-assembled feet using the M6 screws provided, as shown in Fig. 1.
The metal spikes (x) are height-adjustable so as to guarantee the stability of the speaker. To do this,
loosen the top lock nut (z) and adjust the spike by turning it. Once the right setting has been found,
tighten the lock nut again.
Rubber inserts are screwed into the bottom of the cone spikes. These ensure optimum stability on
smooth, hard floor coverings, such as laminate or tiles. The rubber inserts can be replaced with metal
inserts (included in the package). This variation is better suited for carpets, for example.
GENERAL INFORMATION ABOUT CONNECTING YOUR HECO AURORA LOUDSPEAKERS
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 turn 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. 2)
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 HECO AURORA LOUDSPEAKERS IN STEREO MODE
In the ideal configuration the speakers and the listening position should form an equilateral triangle.
When the left and right speakers are the same distance from the listening position their sound arrives
at the same time, resulting in a harmonious, natural music reproduction. (Fig. 3)
There should be a clear line of sight between the loudspeakers and the listening position. Any sound-
absorbing or reflecting obstacles in the path will distort the sound. When you install the loudspeakers
the following distances should be maintained:
