Heco AURORA 1000 Mode D'emploi page 9

Floorstanders: at least 20 cm away from the rear wall and at least 30 cm from the side walls. This will
prevent excessive emphasis of the bass range.
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, 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. 8a), bi-wiring (Fig. 8b) and bi-amping (Fig.
8c).

HECO AURORA SUB 30A
