Lencore
All Wire must be UL Usted, Plenum Rated, 18 gauge, stranded, non-shielded
NOTE
If private offices are included, units should be set
lower in these offices. Suggest 3 clicks on
center switch and 1/2 turn on gain control.
On each main (master) unit, turn each center volume control on the main
(masters) seven clicks & the blue gain control 3/4 clockwise. This is especially
helpful when using a CVC unit. In that case, if the volume is slightly up or down,
all of the units can be adjusted by the CVC. This saves a great deal of time. This
may vary depending on the quantity of units and the height of the plenum area.
Masking units come from the factory pre-set for mineral fiber ceiling tile. If glass
fiber ceiling tile is used, the contour switch must be turned 3/4 to the left towards
the pink spectrum
Leave enough cable at each ceiling opening so that you have an extra 3-5 ft. This
cable will be made into a loop once the unit has been hung and put in the ceiling
using a 7” wire tie. The cabling connecting the units should not be too tight. Once
installed, cable cannot touch the ceiling (use the wire ties to accomplish this).
