NTRODUCTION The KELTIK AKTIV playback system is designed to provide outstanding
musical performance. The KELTIK AKTIV crossover maximises the information sent to the
KELTIK loudspeaker by accurate division of the signal from the pre-amplifier to the separate
power amplifiers. The KELTIK loudspeaker uses the unique patented ISOBARIK bass driver
principle, which gives accurate, musical bass response.
Your hi-fi system performs at its best when used with the highest quality source. The better the sound
from your turntable, tuner or CD player the better the sound you will hear from your KELTIK AKTIV
playback system.
ACTIVE PLAYBACK With a passive loudspeaker, the signal from the amplifier is divided 'into three
frequency bands. (bass, mid and treble) by a passive filter built into the loudspeaker cabinet. This is
powered by the signal itself, absorbing some of the amplifier power, and preventing the amplifier from
accurately controlling the loudspeaker.
Although the highest quality components are used in Linn loudspeakers, there are several fundamental
limits to the performance of a passive loudspeaker system.
An active crossover frees the loudspeaker system from these limits. It accurately divides the signal from
the preamplifier into three frequency bands, and feeds each to its own power amplifier. The loudspeaker
drive units are directly controlled by the power amplifiers. The electronic circuitry of the active crossover
makes it possible to control the drive units in the KELTIK precisely and over an extended frequency
range.
The combination of active crossover, high power amplifiers and advanced loudspeaker drive units in the
KELTIK system results in an extremely accurate musical system which is capable of playing music at
realistic sound levels.
The KELTIK AKTIV has been extensively optimised to work with the KELTIK loudspeaker. It will not work
with any other loudspeaker. We strongly recommend that it be used with Linn power amplifiers.
