MAGNAT QUANTUM 1000 S - 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 1000 S 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 cables 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. 3a), bi-wiring (fig. 3b) and bi-amping (fig. 3c).
HOME CINEMA OPERATION WITH SUBWOOFER
An active subwoofer is recommended for home cinema mode, especially where shelf-top or smaller tower loudspeakers are used
as front speakers. Please refer to the separate operating instructions supplied with this product.
CONNECTING TO AN AV RECEIVER
Figs. 4 and 5 show two different methods of connecting to AV receivers.

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 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.
THE SOUND YOU CAN'T HEAR...
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.
