USER MANUAL Ambient 44 F HECO

At the end of the product's useful life, please dispose of it at appropriate collection points provided in your country.

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.

GENERAL INFORMATION ABOUT CONNECTING YOUR HECO AMBIENT 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. 1 + 2). 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. 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!

WALL MOUNTING

The Ambient 11F, 22F and 44F speakers are designed as wall speakers and offer two wall-mounting options:

1. Attached to the rear are 4 metal fixtures that allow the speaker to be hooked onto two screws fitted to the wall. The speakers can be fitted to the wall vertically or horizontally. The logo on the cover frame is fitted in such a way that it can be easily turned to match the direction of the speaker. Figure 5 - 8 provides information about the screw spacing and the screw dimensions.

2. There are 4 additional threaded inserts on the back (centre of the housing), which allow the use of a VESA standard wall bracket. The hole size is 100mm× 100mm , M4 thread.

Important information/safety instructions:

The customer is solely responsible for the use of wall brackets / speakers attachments.

The customer is also solely responsible for the secure attachment of the speaker bracket to the wall and the selection of suitable mounting material (e.g. screws, wall plugs, etc.), while taking account of the weight and construction of the speaker and the condition of the wall.

THE HECO AMBIENT 11 F, 22 F AND 44 F 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.

The HECO Ambient loudspeakers are ideal for use with the Ambient Sub 88 F active subwoofer.

Fig. 9 shows a method of connection. Please also refer to the subwoofer's and your amplifier's operating instructions.

THE HECO AMBIENT 11 F, 22 F AND 44 F IN HOME CINEMA MODE

The front speakers are placed on the left and right at the same distance from the TV as far as possible, and at ear level. The 22F and 44F models, mounted vertically, are best suited as front speakers. (fig. 4)

The centre speaker is hung in the middle, below or above the TV. The 44F model is best suited as a centre speaker. It should be fitted horizontally.

The rear speakers are placed on the left and right next to or, preferably, behind the listening position at ear level or slightly higher. The 11F and 22F models are best suited as rear speakers.

In the AV receiver setup, the crossover frequency of the front and rear channels should be set to approx. 80 Hz, if possible.

The recommendations in the previous chapter otherwise apply.

AUTOMATIC CALIBRATION

A lot of modern AV amplifiers and receivers provide the option of automatic system calibration via microphone. Calibration is advisable as the levels and distances of all the loudspeakers are determined automatically and, depending on the calibration system, the frequency responses of the connected speakers are also corrected in order to compensate for poor room acoustics.

Please read the user guide for your AV amplifier or receiver in this regard.

THE HECO AMBIENT SUB 88 F SUBWOOFER

The Ambient Sub 88 F active subwoofer visually and acoustically ideally matches the other loudspeakers in the Ambient series. Please refer to the separate operating instructions supplied with this product.

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 lacquered surface is best cleaned with a mild household cleaner. On no account use furniture polish or similar products on these surfaces. Please also do not use a microfiber cloth as this may damage the surface.
