This manual applies to all types available: COLS41-COLS81- COLS101-COLS141 ( 66 mm wide)
and COLW41-COLW81-COLW101 (100mm wide).
The APart COL series speakers are more than just nice looking columns speakers: COL series
speakers have been designed as highly effective line array speakers, featuring excellent vertically
controlled directivity, wide horizontal directivity, high sensitivity and high power handling. COL
series speakers offer you very clear and natural speech reproduction, while music performs very
pleasing too.
Drastically improved audio directivity results in wider coverage range over longer distance. This
means that they cover a wider area than conventional column speakers, so less speaker-cabinets
are needed for achieving the same sound pressure level in a certain area. Also there will be
reduced problems with microphone feedback that is easily generated in reverberant locations. The
especially developed drivers with extended frequency response and low distortion give much better
speech intelligibility. COLS series acoustic response has been specically tailored for speech where
COLW series are ideal for speech and music reproduction.
Thanks to their unobtrusive appearance and excellent acoustic directivity, COL series speakers can
be used in highly reverberant spaces, such as churches, houses of worship, railway stations, as
well as conference rooms, recreational areas or sports facilities. The speaker cabinets are made of
a sturdy extruded aluminum, and all material and construction has been adapted to be used for both
indoor as outdoor, so weather proof and even impact proof (f.e. footballs).
Both 100 volt and low impedance (Lo-Z) connections are provided for increased installation exibil-
ity. 100V line with several transformer power taps as well as low impedance connectors are hidden
inside the cabinet. To access the connector, open the cabinet: remove the two philips screws at the
bottom of the enclosure, see picture below. In normal indoor situations you can feed the cable(s)
through the rubber cable sleeves, for IP66 compatibility, use the supplied cable entries and washers
provided in the accessory kit. A second cable entry point is present for easily looping the cable
through.
