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 COLORS 100
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). Loudspeaker
cables with CE-compliant banana or single-pin plugs (4 mm) or forked fittings can also be used.
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 COLORS 100 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: Shelf loudspeakers
should also be as free-standing as possible, the distance to the sides to walls and items should be at least
10 cm if possible, the tweeters should be located at ear height.
If the speakers are arranged on a shelf,
there should be a minimum clearance of 10 cm to the shelves above or the ceiling.
MAINTENANCE
The lacquered surface is best cleaned with a mild household cleaner. On no account use furniture polish
or similar products on these surfaces.
HOW TO AVOID DAMAGE TO YOUR VALUABLE SPEAKERS
All HECO loudspeakers are designed and built for optimum sound reproduction with the tone controls in
the central position – i.e. with “linear” amplifier output. Turning up the bass and treble controls too far
delivers more power to the woofers and/or tweeters, and at high volumes this can actually destroy the
speaker units!
