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.
FITTING THE FEET (AURORA 1000, 900 AM AND 700 ONLY)
The 2 feet included in the delivery package must be fitted to the loudspeaker before use. To do this, place the speakers on a clean, stable base with the bottom facing upwards. It is better not to remove the protective bag until after fitting has been completed so as to avoid damage to the paint surface.
First fit the four metal spikes to the two traverses, as shown in Fig. 1: Two spikes each (x) are screwed into the threaded holes in the traverses (w) from below as far as they will go. From above, the lock screw (z) is then fitted and tightened.
Now fit the two pre-assembled feet using the M6 screws provided, as shown in Fig. 1.
The metal spikes (x) are height-adjustable so as to guarantee the stability of the speaker. To do this, loosen the top lock nut (z) and adjust the spike by turning it. Once the right setting has been found, tighten the lock nut again.
Rubber inserts are screwed into the bottom of the cone spikes. These ensure optimum stability on smooth, hard floor coverings, such as laminate or tiles. The rubber inserts can be replaced with metal inserts (included in the package). This variation is better suited for carpets, for example.
GENERAL INFORMATION ABOUT CONNECTING YOUR HECO AURORA LOUDSPEAKERS
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 mm ^4 for lengths up to 3 m and at least 4 mm ^2 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. 2)
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.
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!
THE HECO AURORA LOUDSPEAKERS IN STEREO MODE
In the ideal configuration the speakers and the listening position should form an equilateral triangle.
When the left and right speakers are the same distance from the listening position their sound arrives at the same time, resulting in a harmonious, natural music reproduction. (Fig. 3)
There should be a clear line of sight between the loudspeakers and the listening position. Any sound-absorbing or reflecting obstacles in the path will distort the sound. When you install the loudspeakers the following distances should be maintained:
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, 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.
SETTING UP: The recommendations given in the previous sections generally apply to the positioning of the speakers. When used as a front speaker, the distance from the listening position should be at least 2.5-3 m. The speakers should be directed slightly towards the listening position.
The AURORA 900 AM can also be used as rear speakers (home cinema system with four Atmos height channels, 5.x.4 configuration). The height channel is then used as rear high. However, it should be ensured that the speakers can be set up clearly behind the listening position (distance at least 1-1.5m). The distance between the two speakers should roughly correspond to the distance between the front speakers. A possible setup configuration is shown in Fig. 3b.
CONNECTING: The speaker has two connection terminals at the rear. The lower terminal is assigned to the main speaker, and the upper one to the treble speaker (Fig. 5d).
Please note:
The protective cover of the treble speaker may only be removed for servicing purposes.
HECO AURORA SUB 30A
The AURORA SUB 30A active subwoofer visually and acoustically ideally matches the other loudspeakers in the AURORA series. Please refer to the separate operating instructions supplied with this product.
CONNECTING TO AN AV RECEIVER

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!
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.
Amplifiers, tuners and CD players can all produce inaudible high-frequency signals – and this doesn't only apply to cheap products. If your tweeters fail at low or medium volumes you should have a qualified technician check your system components for dangerous inaudible signals.
MAINTENANCE
The surface is best cleaned with a mild household cleaner. On no account use furniture polish or similar products.
