desks and, if carefully placed appear fairly
innocuous in a room. Further advice on how
to place the loudspeaker is described in the
operating manual.
If the subwoofer and main loudspeakers
are placed properly some of the low fre-
quency problems associated with free stand-
ing speakers can be avoided.
Why active loudspeakers?
There are various reasons why active loud-
speakers are preferable to passive alterna-
tives, the most dominant being the integrated
construction allowing better optimization of
the system performance. The loudspeakers
are always delivered as a complete factory
calibrated system, consisting of all ampli-
fiers, crossover electronics and speaker
cabinets.
In an active loudspeaker system the ampli-
fiers are connected directly to the drive units.
Distortion anomalies and losses caused by
passive crossovers are completely avoided
resulting in better sound quality and maxi-
mum acoustic efficiency.
For every model of monitor the associ-
ated amplifiers have a unique design includ-
ing driver overload protection. The overload
protection detects signals that are above the
drivers safe limits preventing damage. This
makes the system immune to overloads
and spurious signals which synthesizers,
sequencers and multimedia sources, such as
sound cards, can occasionally produce.
The crossover and phase responses
are optimized for each particular model to
achieve highly accurate system performance.
Consequently every model has the same
neutral sound.
