Check the structural wall to ensure that it can support a load four times the weight of the final setup. If
not, the wall structure must be reinforced. Refer to local building standards and codes to verify that
the installation meets all the relevant regulatory standards.
The mount must also include openings for access to power connections or for use as cable pass-
through.
(2) Universal Projector Bracket.
The bracket shall be able to support projectors up to 25 pounds.
The projector bracket must have independent adjustments of horizontal tilt or roll (± 4 degrees of
horizontal tilt), vertical angle or pitch (± 25 degrees of vertical angle), and rotation or yaw (360
degrees of rotation).
The projector bracket shall also use a 1.5” NTP (National Tapered Pipe) threaded pipe adapter for
mounting a projector pole.
The projector bracket should also maintain positioning adjustments even if the projector is removed
for service.
The bracket should also feature security flanges that enable the entire unit to be locked to prevent
theft.
c. Multi-Product Mounting Kit.
(1) The multi-product mounting kit houses the key electronic components of the A/V system including the
switcher, audio amplifier and power supply. The kit shall support mounting in close proximity to the
display device, and protect the contained components from tampering and theft.
2. Media Source Switching:
a. System source selection and switching shall be provided by a PVS A/V Switcher.
(1) The switcher shall have two (2) RGB video inputs capable of VGA - UXGA RGBHV, RGBS, RBsB
and RsGsBs input resolution via (2) two pairs of female RJ-45 connectors.
(2) The switcher shall have two (2) inputs that can be configurable for either composite video via two (2)
female RJ-45 connectors or two (2) additional RGB video inputs capable of VGA - UXGA RGBHV,
RGBS, RBsB and RsGsBs input resolution via (2) two pairs of female RJ-45 connectors.
(3) Audio input for switched video sources shall be via four (4) stereo, balanced/unbalanced inputs via
the same four and/or six (4 and/or 6) RJ-45 RGB and Composite video connectors.
(4) The switcher shall have a switched auxiliary audio input to support audio from video sources that are
directly connected to the projector or sources that only offer audio content.
(5) The switcher shall have two video outputs, one (1) RGB output capable of outputting VGA - UXGA
RGBHV, RGBS, RBsB and RsGsBs (following input type) via a 15-pin HD female connector and one
(1) composite video via one (1) RCA female connector.
(6) Connection from the switcher to the display device shall be provided with one 3’ VGA to VGA and one
3’ composite video cable.
(7) An onboard audio amplifier shall provide gain / volume adjustment from -10db to +10db, adjustable in
1 db steps. The speaker amplifier shall have two (2) channels, one (1) stereo (default) or dual (2)
mono channels via one (1) 5.0 mm 4 pole captive screw connector. The output of the amplifier shall
be 25 watts (rms) per channel at 2/4/8 ohms.
(8) In addition to the stereo / mono speaker output, an additional audio output that will produce line level
output shall also be available. This line level audio output must be capable for being set at either
“fixed” or “variable” and with Balanced or Unbalanced settings.
3. Media Source Control:
a. Classroom media sources shall be controlled with a MediaLink Controller.
