Lencore Spectra Classic: Installation and Operations Manual - Manual (Page 4)

PRESETTING CVC CENTRAL VOLUME CONTROL OR RCVC
Turn each main (master) center volume control to the 7th position.
Turn the blue gain control 3/4 clockwise. Put the CVC blue central volume control in
the middle position. This is a good starting point. Then only minor volume adjustments
should be made. This setup will vary from location to location and will also vary
depending on plenum heights.
HANG SOUND MASKING UNITS
Use Erica Multi-Function Clips, 4-Z-3-4 to hang units. Hang them approximately 10”
above the ceiling tile at the designated location. Each Spectra® unit is suspended from
the nearest T -Bar hanger by chain. It is important you hang the units at a uni form height
throughout, otherwise, you risk the chance of less uniformity of sound when the units
are turned on.
FIND OUT IF PLENUM RATED TIE WRAPS MUST BE USED ON YOUR
PARTICULAR PROJECT
The units are normally placed 6-9ft. from the hard walls and usually 12-15 ft. apart. Once
you get in the ceilings, there are almost always changes that need to be made. You may
run into heater ducts and other obstacles that make it impossible to install the units in
the exact spot that the plans suggest. If you need to hang the unit in a different
area, that’s okay. Hang the units as close to the suggested area as possible. A team
member should follow behind the cable person(s) and begin hanging units.
New construction may require that units be attached directly to the deck above. Verify
what method must be used for hanging units prior to undertaking the installation.
CONNECT UNITS
This is the most critical part of the entire operation. The most thorough members
of your team should do this task. All of the efficiency of your installation can be lost if
you have connec tion problems. Units are wired in parallel.
Supply each of the team members connecting the units with a wiring diagram.
