Heco AURORA 900 AM Mode D'emploi page 9

Bookshelf speakers: 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.
Spikes (floorstanders): you should use the supplied spikes when setting the speakers up. This isolates
them from the supporting surface, preventing unpleasant resonance effects. You can choose
between metal and hard rubber spikes for the standing speakers. The spikes are screwed into the
threaded bushes on the bottom of the speaker.
HECO AURORA LOUDSPEAKERS 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. (Fig. 4)
HECO AURORA 1000, 900 AM, 700, 300 – BI-WIRING AND BI-AMPING
Bi-wiring means using separate cables to carry the high and low audio frequencies. Bi-amping takes
this idea one step further and uses separate power amplifiers as well as separate cables for high and
low frequencies. Bi-amping in particular produces an additional improvement in sound reproduction
quality.
The special connection terminals of the AURORA loudspeakers support both conventional connection
and operation in bi-wiring and bi-amping modes. There are four screw terminals on each speaker.
The top pair are for the tweeter (high frequencies), the lower pair for the woofer (low frequencies).
The factory-installed metal strips connecting the positive and negative terminals are for conventional
2-wire connection and must be removed for bi-wiring and bi-amping operation. The pictures below
show the correct set-up for conventional operation (Fig. 5a), bi-wiring (Fig. 5b) and bi-amping (Fig. 5c).
HECO AURORA CENTER 30
The AURORA CENTER 30 loudspeaker visually and acoustically ideally matches the other AURORA
models. The loudspeaker is placed immediately underneath the television set. Otherwise please
adhere to the general recommendations outlined in the previous chapters.
HECO AURORA 900 AM
3-way bass reflex floorstanding speaker with integrated 2-way Dolby Atmos® module
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 add-on loudspeakers or via add-on speakers
integrated into the front and rear loudspeakers like the AURORA 900 AM. 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 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.
