Grounding guidelines
Extron MTP 1500RL 15HD RS SEQ 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 1500RL 15HD RS SEQ 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 on 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 6 — Peaking and Level
Adjust the image sharpness using the Peaking control. Increased peaking compensates for mid- and high-frequency

detail loss. The LED lights red when minimum (zero) or maximum peaking is reached.
Adjust the image brightness using the Level control. View the image and adjust either control for the best image quality.
Step 7 — Skew Compensation
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. Set the skew delay to zero for red, green, and blue by using a Tweeker or small screwdriver to press and hold

the Select button for 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. Adjust the furthest left video signal by using a Tweeker or screwdriver to press and release the Select button until
the LED for the left-shifted color lights.
D. Slowly rotate the Adjust control clockwise until the shifted color is properly aligned.
E. Repeat steps C and D to align the third color if needed.
