Heco Music Style Center 2 - Manual (Page 7)

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.
GENERAL INFORMATION ABOUT CONNECTING YOUR HECO MUSIC STYLE 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. 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!
THE HECO MUSIC STYLE 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. 2)
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:
Floorstanders: at least 20 cm away from the rear wall and at least 30 cm from the side walls. This will
prevent excessive emphasis of the bass range.
Bookshelf speakers: shelf loudspeakers should also be as free-standing as possible, the distance to the
sides and rear to walls and items should be at least 10 cm, the tweeters should be located at ear height.
Spikes (floorstanders): you should use the supplied spikes when setting the speakers up. This isolates
them from the supporting surface, preventing unpleasant resonance effects. You can choose between
metal and hard rubber spikes for the standing speakers. The spikes are screwed into the threaded bushes
on the bottom of the speaker.
HECO MUSIC STYLE LOUDSPEAKERS AS A FRONT OR REAR LOUDSPEAKER
The front loudspeakers are positioned at ear height on the left and right as equidistant from the television
as possible. The rear loudspeakers are placed at ear height or a little above on the left and right besides
or better behind the listening position. (Fig. 3)
