(usually built into the audio equipment) longer cable runs
and easier multiple loudspeaker installation designs can
be achieved. The drawbacks of this type of system include
potential degradation of sound quality if the transformers
are not of suitable quality and the inability to adjust the
relative sound levels between the different loudspeakers
(although some can be adjusted at time of installation by
using different transformer tappings).
Single source line array – this type of loudspeaker system
comprises multiple loudspeakers in an array of enclosures
place near the front of the space. Each element of the
enclosure is designed to give a very specific dispersement
pattern and through the use of digital sound processing
a much more even front-to-back dispersement can be
achieved i.e. listeners at the rear of the space will hear
sound sources at the same sound level as those at the
front. This type of loudspeaker system requires specialist
design and installation services to ensure optimal
performance in the specific space.

Regardless of the amplifier/loudspeaker technology deployed within
a particular learning space the configuration controls (e.g. power
amplifier output levels) should be inaccessible to end users with
only the master volume control via the teaching station control panel
available.
