Spikes (Quantum Standlautsprecher):

Dear MAGNAT Customer,

Congratulations on your fine new loudspeakers and thank you very much for choosing MAGNAT! You have made an excellent choice. The high-quality speakers produced by MAGNAT are renowned all over the world.

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

FITTING THE FEET (QUANTUM 727 AND 725 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 metal 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 plastic washers (y) are first placed over the protruding threads and 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 (y) 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 MAGNAT QUANTUM 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 ^2 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 MAGNAT QUANTUM 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:

Quantum 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.

Quantum 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 (Quantum 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.

MAGNAT QUANTUM 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)

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 Quantum 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).

MAGNAT QUANTUM CENTER 72

The QUANTUM CENTER 72 loudspeaker visually and acoustically ideally matches the other QUANTUM 720 models. The loudspeaker is placed immediately on or under the television set. Otherwise please adhere to the general recommendations outlined in the previous chapters.

MAGNAT QUANTUM 7230A

The QUANTUM 7230A active subwoofer visually and acoustically ideally matches the other loudspeakers in the QUANTUM 720 series. Please refer to the separate operating instructions supplied with this product.

CONNECTING TO AN AV RECEIVER

Figs. 6 and 7 show two different methods of connecting to AV receivers.

HOW TO AVOID DAMAGE TO YOUR VALUABLE SPEAKERS

All MAGNAT 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.
