Heco The New Statement - Manual (Page 7)

Tri-wiring requires a third cable, tri-amping requires an additional third amplifier.
Four cable bridges have been supplied.
Please connect the loudspeaker terminals for conventional use with the y-cable bridges (one cable shoe
and two plugs) in accordance with Fig. 2 a – d.
Please use the other cable bridges (one cable shoe and one plug) as shown in Fig. 2 e – l for bi-wiring
and bi-amping.
No bridges may be used for tri-wiring and tri-amping. Figs. 2 m – t show the connections to the amplifier(s).
CONNECTING YOUR HECO THE STATEMENT LOUDSPEAKERS
Warning: Only hi-fi amplifier loudspeaker outputs may be connected to the loudspeaker terminal.
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.
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.
The terminal is designed for 3 cord sets:
· Connection via banana plugs (fig. 3a)
· Connection via clevis type fittings (fig. 3b)
· Non-ready-made (fig. 3c)
Strip 10 – 15 mm of insulation from the ends of non-ready-made cables. Twist the ends – this is much
better than tinning them with solder – insert them in the terminals and tighten the terminal screws firmly.
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!
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!
If the output of your amplifier is significantly higher than the rated power handling capacity of your
speakers extremely high volumes can physically destroy your speakers. This doesn’t actually happen
often but you should be aware that it is possible.
