Heco AM 200 El Manual Del Propietario página 5

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.
ABOUT DOLBY ATMOS
Dolby Atmos is a new audio standard for cinemas and home cinemas. Atmos brings a third dimension into
the soundscape for the first time in the form of treble channels. The treble channels are emitted either by
additional loudspeakers like the HECO AM 200 or via add-on speakers integrated into the front and rear
loudspeakers. For even distribution of the treble sound field that is not locatable for the human ear, the
add-on loudspeakers emit their sound into the room in the direction of the ceiling. The reflection of this
sound then reaches the listeners, giving the impression of a three-dimensional soundscape.
The use of on-wall or in-wall ceiling loudspeakers is also possible as an alternative for emitting the treble
channels. However, this involves considerably greater effort and expense in terms of installation and
wiring. Atmos-certified add-on loudspeakers therefore represent a simple and practical possibility for
expanding an existing multi-channel loudspeaker set to include Atmos channels.
Please note that, for a true Dolby Atmos experience, both the source material (e.g. Bluray) and the
electronics (e.g. AV receiver) have to meet the Dolby Atmos audio standard.
SETUP
Please check first whether the top of your existing front speakers are of a suitable size for positioning the
HECO AM 200's. An area of around 150x220mm is needed. For them to be positioned securely, all four
feet of the additional loudspeaker must be in contact with the front speaker. Now place one HECO AM
200 on the top of each of the front loudspeakers with their baffles slanted to face into the room (Fig. 2).
If this is not possible or desirable, place the AM 200's as close as possible to the top of the front speakers,
e.g. on a shelf.
Please ensure that the main axis of the integrated coaxial loudspeaker has a clear line of sight to the
ceiling without any sound-absorbing or reflecting obstacles. Only in this way can the desired sound
reflection via the ceiling function as wished.
If you are installing four HECO AM 200's, position the rear pair on the top of your rear loudspeakers. If this
is not possible (e.g. because of the rear speakers being suspended high up), place the Atmos speakers
below them at the same height as the front AM 200's. The baffles must be slanted to face into the room.
Please also note the set-up recommendations regarding obstacles.
The sides of all the loudspeakers should be at least 10 cm away from walls and other adjacent surfaces.
START-UP
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
