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.
SET-UP INFORMATION
BellaDonna should if possible be set up without obstruction and slightly inclined towards the place
of listening (fig.1). 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.
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.
For the set-up, we recommend the optional BellaDonna speaker stand. This has been specially
developed for the BellaDonna loudspeakers. This sturdy stand provides a secure base and optimal
setup height for the speakers. For installation, please refer to the assembly instructions enclosed with
this product.
If you would like to use an alternative speaker stand, please make sure it is stable and suitable for the
size and weight of the speaker.
If you use the speaker without a stand, e.g. on a sideboard, the tweeters should be more or less at
ear level. If possible, the distance to the side and rear should not be less than 20 cm from walls and
objects. This avoids excessive bass reproduction.
GENERAL INFORMATION ABOUT CONNECTING YOUR HECO BELLADONNA 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!
You can, of course, also use cables with banana plugs (4mm) or cable lugs.
