Step 6 — Power
Wire the 2-pole captive screw connectors for the included external 12 VDC power supplies (see
image a on the right). Plug them into all units.

Grounding guidelines

Extron MTP 15HD A products can be adversely affected by electrostatic discharge (ESD) if they
are not grounded correctly.
To prevent malfunctions or product damage, an experienced installer can correctly ground an
Extron MTP 15HD A product in either of two ways:
• Ground the power input port — Insert one end of the grounding wire to the negative or ground
pin on the power input connector (see image a on the right). Tie the other end of the wire to an
earth ground.
• Ground the chassis — Use a connector hex nut (see image b the right). Tie the other end of
the wire to an earth ground.
If you have any questions about how to ground a product in a specic application, contact an Extron technical
support specialist.

Step 7 — Pre-Peak, Peaking, and Level

• Transmitter Pre-Peak switch — View the image and set the Pre-Peaking switch for the best image
quality to correct for long cable runs of the entire system (including all daisy-chained receivers).
• Receiver Peaking control — View the image and adjust the Peaking control for the best image sharpness. Minimum
RGB
PEAKING
LEVEL
setting (full counterclockwise) is zero peaking.
• Receiver Level control — View the image and adjust the Level control for the best brightness level.

Step 8 — Skew Compensation (SEQ Receivers)

Pair skew can be measured with test equipment or by viewing a crosshatch test pattern. The SEQ receivers have built-in
skew compensation capabilities. Adjust the equalization as follows:
A. Zero the skew delay for red, green, and blue by using a small screwdriver to press and hold the Select button for
DELAY
RED
GREEN
BLUE
SELECT
3 seconds. When the Red, Green, and Blue LEDs all go out, release the Select button.
B. Use UTP cable test equipment or examine the displayed image to determine which video signal — red, green, or
blue — is shifted furthest to the right.
C. Select the furthest left video signal by using a small screwdriver to press and release the Select button until the LED
for the left-shifted color — Red, Green, or Blue — lights.
D. Slowly rotate the Adjust control clockwise until the selected color is properly converged.
E. If the remaining colors are left-shifted, repeat steps C and D.
