Connecting
OW Series speakers are connected to speaker cables via screw terminal blocks located
behind their connection panels. The connection panels, supplied separately within the
shipping box, incorporate cable entry ducts with sealing glands that can be tightened to
restrain the cable and prevent the ingress of moisture and dust. Each terminal blocks
carries two pairs of positive and negative terminals. The second pair of terminals is provided
to enable speakers to be daisy-chained when 70/100V amplification is used. In this case all
but the last speaker in a chain will require connection to two speaker cables.
Note
The maximum speaker cable outer dimension that can be used OS Series speakers is 8
mm. The minimum outer cable dimension required to ensure dust and water resistance is 2
mm. With small diameter cable it may be appropriate to seal the cable gland with silicone
sealant.
The selection of appropriate speaker cable gauge will depend on the type of application
used and length of cable from amplifier to speaker. With conventional 'low-z' amplification,
cable with conductors of at least 1.5mm2 cross sectional area is recommend. If cable length
from amplifier to speaker exceeds 15m, larger gauge cable should be considered. With
70/100V amplification cable gauge can be reduced, however 0.5mm2 should still be
considered the minimum.
To connect OW Series speaker, proceed as described and illustrated in the following
paragraphs and diagrams.
Ensure that all amplification is switched off when making speaker connections.
Unscrew and remove the male connector body from the female socket block mounted on
the rear of the speaker.
Pass the speaker cable or cables through the connection panel duct. Do not tighten the
sealing gland at this stage.
