Aktiv operation
The term ‘Aktiv’ refers to the proprietary Linn active crossover and loudspeaker
configuration, whereby a loudspeaker’s internal passive crossover is replaced
with external crossovers.
In a passive system, the output from the power amplifier 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 volume.
In an Aktiv system, one channel of amplification is required for each drive unit in
a loudspeaker, and the crossover circuitry is located before the amplifier circuitry.
After the audio signal is filtered by the crossovers the amplifier 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 amplifier
channel to provide a greater degree of control over the loudspeaker.
So in Aktiv mode, the crossovers provide a more precise means of filtering the
signal into the required frequency bands, while allowing the amplifiers to exert
more control over the drive units. This results in significantly improved sonic
performance compared with passive operation.
Important note:
Aktiv operation requires a modification to your loudspeakers and your
Linn amplifiers, which must be carried out by an authorised Linn retailer.
Link strip information
To remove / fit the link strips:
•
Loosen the outer section of each binding post on both rows of terminals.
•
Slide the link strips outwards to remove them.
•
When refitting the strips, ensure that they are fully and correctly inserted.
•
Ensure that all the binding posts are tight (whether the strips are being
refitted or not).
