User manual HECO CELAN 701

[. . . ] Twist the ends ­ this is much better than tinning them with solder ­ insert them in the terminals and tighten the terminal screws firmly (fig. 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. [. . . ] There should be a clear line of sight between the loudspeakers and the listening position. Any soundabsorbing or reflecting obstacles in the path will distort the sound. When you install the loudspeakers the following distances should be maintained: Celan XT 501, 701, 901: at least 20 cm away from the rear wall and at least 30 cm from the side walls. Celan XT 301: 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. This isolates them from the supporting surface, preventing unpleasant resonance effects. You can choose between metal and hard rubber spikes for the standing speakers, while the enclosed hard rubber spikes are used for the shelf speakers. The spikes are screwed into the threaded bushes on the bottom of the speaker. The HECO Celan XT loudspeakers are ideal for use with the Celan XT Sub 32A active subwoofer. HECO CELAN XT 301, 501, 701 AND 901 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. Celan XT 301: if possible, the cross-over frequency for the front and rear channels should be adjusted to approximately 80 Hz in the AV receiver's set-up. Otherwise all the recommendations made in the previous chapter also apply. hECO CELAN XT CENTER 4 The Celan XT Center 4 loudspeaker visually and acoustically ideally matches the other Celan XT models. 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. 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. Weak amplifiers with low output ratings can actually be more dangerous for your speakers at medium volumes because weak amplifiers may overload much faster than powerful ones and this causes measurable and audible distortion, which is extremely dangerous to your loudspeakers. Always turn the volume down immediately as soon as you hear distortion!If you like listening to loud music make sure that your amplifier can deliver at least as much power as the speakers' power-handling rating.
