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!
