Majik 112
Con fi guration options
The Majik 112 loudspeaker offers an array of con fi guration options, as described
below. Connections for each of the methods are shown in the Wiring and amping
con fi gurations section, page 7.
The options are listed in order of increasing sonic performance. Multi-wiring and
multi-amping options offer improvements in sound quality over single-wiring. The
greater the separation of the frequency bands in the power ampli
fi ers, crossover
and cables, the more precise the quality of the playback performance, with Aktiv
operation representing the ultimate con
fi guration (see Aktiv operation , across).
Passive single-wiring:
A single ampli fi er channel connects to the loudspeaker using a single cable.
Passive multi-wiring (bi-wire or tri-wire):
A single ampli fi er channel connects to the loudspeaker using two or three cables.
Passive multi-amping (bi-amp or tri-amp):
Two or three ampli fi er channels connect to the loudspeaker.
Note:
Multi-amping can be combined with multi-wiring, e.g. bi-amping could be
employed with bi-wiring.
Aktiv operation
The term ‘Aktiv’ refers to the proprietary Linn active crossover and loudspeaker
con
fi guration, whereby a loudspeaker’s internal passive crossover is replaced with
external crossovers.
In a passive system the output from the power ampli fi er is passed through the
crossover inside the loudspeaker. A portion of the signal’s energy is dissipated in
the crossover circuitry and is therefore lost. Also, the behaviour of the crossover
and the drive units will differ depending on the listening level.
In an Aktiv system one channel of ampli fi cation is required for each drive unit in a
loudspeaker, and the crossover circuitry is located before the ampli fi er circuitry.
After the audio signal is fi ltered by the crossovers the ampli fi er then supplies power
to the loudspeaker drive unit in the frequency band required by that particular
driver (e.g. midrange frequencies for the midrange driver), allowing each ampli
fi er
channel to provide a greater degree of control over the loudspeaker.
So, in Aktiv mode the crossovers provide a more precise means of fi ltering the
signal into the required frequency bands, while allowing the ampli fi ers to exert
more control over the drive units. This results in signi fi cantly improved sonic
performance compared with passive operation.
Important note:
Aktiv operation requires a modi fi cation to your loudspeaker and your Linn
ampli fi ers, which must be carried out by an authorised Linn retailer.
