Sharpness adjustment
The longer the cable being used, the greater the signal loss. The
image sharpness may be enhanced by turning a peaking
adjustment screw located on the top of the receiver. Increased
peaking can compensate for detail (mid- and high-frequency)
loss from low bandwidth system components or capacitance in
long cables. Adjust this control using the included adjustment
tool (Extron part #100-043-02) while viewing the displayed
image to obtain the optimum picture sharpness. Turning the
control clockwise increases peaking and turning it
counterclockwise decreases peaking.
Mounting
The mountable transmitter (VTT001 MAAP) and mountable
receiver (VTR001 MAAP) may be attached to a wall with either
a stud-mounted wall box or with a wall mounting bracket
(Extron part # 70-163-xx). Both installations require the double
spaced MAAP connector frame, such as the CPM101). The
transmitter/receiver module can also be attached to any Extron
MAAP device that accepts a double spaced A/V connector
panel, or the modules may be rack mounted. The AAP versions
of the transmitter and receiver mount to Extron AAP frames
(see “
Other accessories ” in the appendix).
Preparing the wall box
For wall and furniture mounting installations, the installation
site must be deep enough for both the wall box and the cables.
The box should be at least 2.5" (6.4 cm) deep. Install cables into
the wall, furniture, or conduits before installing a wall box or
bracket.
1. Place the wall box or mounting bracket against the
installation surface, and mark the guidelines for the
opening on the wall or furniture.
2. Cut out the material from the marked area.
3. Insert the wall box/bracket to check the opening’s size and
fit. Enlarge or smooth the edges of the opening if needed.
4. If using a wall box, feed cables through the wall box’s
punch-out holes, and secure them with cable clamps to
provide strain relief.
5. Exposed cable shields (braids or foil) are potential sources
of short circuits. Trim back and/or insulate shields with
heat shrink.
