MTP 15HD A Series • Installation and Operation
c
Peaking control — Peaking affects the sharpness of a picture.
Increased peaking can compensate for mid- and high-frequency
detail loss from low bandwidth system components or
capacitance in long cables. The minimum setting (at the
counterclockwise limit) provides no peaking. The maximum
setting (at the clockwise limit) provides 100% peaking. Adjust
this control to obtain the optimum picture sharpness.
d
Select button (SEQ model only) — This recessed button selects
the Red, Green, or Blue video signal to adjust and resets all three
video signals to a skew delay of zero nanoseconds.
Use a small screwdriver to press and release this button to cycle
among selecting the Red, Green, or Blue video signal to adjust.
The selected signal is indicated by the Red, Green, and Blue
LEDs (
e
).
N
The SEQ receiver automatically saves the setting for the
video signal that is being deselected when you push this
button or when the selection times out after 10 seconds.
Press and hold this button for approximately 3 seconds to set
the skew delay for Red, Green, and Blue to zero. The Red,
Green, and Blue LEDs (
e
) all turn off. Release the button.
e
Red, Green, and Blue LEDs (SEQ model only) — These LEDs
indicate the video signal that is selected by the Select button
(
d
) for skew adjustment using the Delay control (
f
). The LED
of the selected color flashes when skew compensation for the
selected video signal has reached the minimum or maximum
limit.
f
Delay (skew adjustment) control (SEQ model only) —
This control delays the selected Red, Green, or Blue video signal
by up to 62 nanoseconds. The delay is applied in incremental,
2-nanosecond steps. Rotate the control counterclockwise to
reduce the delay or clockwise to increase the delay.
N
The control turns smoothly; it does not have mechanical
steps or high-and low-limit stops.
Watch the displayed image to observe the steps of delay.
The selected Red, Green, or Blue LED (
e
) flashes
to indicate that the control has reached the minimum
(counterclockwise rotation) or maximum (clockwise
rotation) limit.
