La Diva - Speaker HECO - Free user manual and instructions

USER MANUAL La Diva HECO

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

We congratulate you on acquiring this exclusive HECO product.

Acquiring this loudspeaker will enable you to fulfil your wildest dreams for listening to natural, unadulterated sound.

Please study the instructions and information below carefully before using your new loudspeakers.

SET-UP INFORMATION

LA DIVA should if possible be set up without obstruction and slightly inclined towards the place of listening (fig. 1).

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.

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.

FITTING THE FLOOR PLATES

The floor plates provided must be fitted to both speakers 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 floor plate, as shown in Fig. 2a: Four spikes (x) are screwed into the threaded holes in the floor plate (y) from below as far as they will go. The lock screw (z) is then fitted and tightened.

Now fit the pre-assembled floor plate using the M6 screws provided, as shown in Fig. 2b.

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.

BI-WIRING AND BI-AMPING, TRI-WIRING AND TRI-AMPING

LA DIVA possesses a field with eight screw terminals, which - besides conventional connection to an amplifier - also permit bi-wiring/bi-amping and tri-wiring/tri-amping.

The (-) terminals are on the left.

The top terminals are connected to the treble branch, the middle ones to the crossover filter's mid-range branch and the bottom terminals to the bass branch. The additional terminal at the top right allows the treble range to be elevated by 2dB, the other terminal in the centre right allows the mid-range to be lowered by 2dB.

The appropriate setting depends on the listening space, on where the loudspeakers are placed and naturally on personal taste.

In rooms with high absorption (e.g. heavily upholstered furniture and curtains), the +2dB tweeter setting is recommended and where the speakers are set up in close proximity to a wall at their backs and rooms with low absorption, the -2dB setting is recommended.

Bi-wiring means that high and low frequencies are transported through separate cables. The bi-amping method also requires a second final amplifier in addition to the second cable.

Tri-wiring requires a third cable, tri-amping requires an additional third amplifier.

Four cable bridges have been supplied.

Please connect the loudspeaker terminals for conventional use with the y-cable bridges (one cable shoe and two plugs) in accordance with Fig. 3 a - d.

Please use the other cable bridges (one cable shoe and one plug) as shown in Fig. 3 e - l for bi-wiring and bi-amping.

No bridges may be used for tri-wiring and tri-amping. Figs. 3 m - t show the connections to the amplifier(s).

CONNECTING YOUR HECO LA DIVA LOUDSPEAKERS

Warning: Only hi-fi amplifier loudspeaker outputs may be connected to the loudspeaker terminal.

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 2.5mm^2 for lengths up to 3m and at least 4mm^2 for lengths above 3m .

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.

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.

The terminal is designed for 3 cord sets:

• Connection via banana plugs (fig. 4a)
• Connection via clevis type fittings (fig. 4b)
  Non-ready-made (fig. 4c)

Strip 10 - 15mm of insulation from the ends of non-ready-made cables. Twist the ends – this is much better than tinning them with solder – insert them in the terminals and tighten the terminal screws firmly.

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!

MAINTENANCE

The lacquered surface is best cleaned with a mild household cleaner. On no account use furniture polish or similar products on these surfaces.

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.
