Heco Install INW 602 - 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.
HECO INC/INW LOUDSPEAKERS - SPECIALLY DESIGNED FOR CEILING FITTING/WALL
MOUNTING
Heco INC/INW speakers have an ingenious clamping mechanism that enables you to easily fit them into
a hole cut into a baffle. The easiest way is to fit them in a plaster board or similar ceiling. When using an
opening in a masonry wall, a plaster or timber board is also needed. For the fitting dimensions, please
see the technical data given at the end of the manual.
Removing the grille (fig. 1)
INC 802 / INC 602 / INC 2602 (fig. 2)
The clamping mechanism for attaching the speaker can be accessed after removing the protective grille.
Loosen the screws and move the clamps to position A. After placing the appliance in the cut-out hole,
tighten the screws. This automatically turns the clamps to position B and tightens them.

After removing the protective grille first dismantle the baffle using the 6 visible cross-head screws (fig.
3.1). Loosen the screws and move the clamps to position A. After placing the appliance in the cut-out
hole, tighten the screws (fig. 3.2). This automatically turns the clamps to position B and tightens them.
GENERAL INFORMATION ABOUT CONNECTING YOUR HECO 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 1 mm² for lengths up
to 3 m and at least 1.5 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 and twist the ends. The loudspeaker terminals
are equipped with a clamping mechanism (fig. 4). Press the terminal head down and guide the stripped
cable end into the hole on the side. On releasing the terminal head, the cable is secured, ensuring the
best possible contact.
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!
ACOUSTIC ADAPTATION
The crossover facilitates individual sound adjustment of the speaker system via high-quality jumpers:
1. Tweeter level adjustment (treble) (fig. 5A)
2. Mid-range adjustment (midrange) (fig. 5B)
