Optimizing the Video
Each TP input has a level and peaking adjustment. Most MTP transmitters and half of
the MTPX Plus TP outputs have a pre-peaking feature. TP inputs and outputs have skew
adjustments. Set these adjustable features as follows for the best image quality:
NOTES: • For all of the settings in this section (with the exception of the Pre-Peak
switch on the transmitter in step 1), see the MTPX Pictures settings and
MTPX configuration settings menu items in “
Tools menu ”, on page 114.
These settings can also be made using SIS commands (see the
“
Programming Guide ” section) or the built-in HTML pages (see the “ HTML
Operation ” section).
• Unless the TP cables are changed, these adjustments should need to be made
only once, during installation.
Before you start optimizing, set all input level and peaking, input and output skew, and
output pre-peak settings to either zero or off.
MTP Transmitter Pre-Peak Selection
For inputs from MTP T 15HD products only — If the cable between the MTP transmitter
and the MTPX Plus is 300 feet (91.4 m) or longer, turn the Pre-Peak switch on the
transmitter to on. For shorter cables, turn the switch off.
MTPX Level/Peaking Setting
Auto calibration
The simplest and surest way to set the input level/peaking is to use the MTP signal generator
(included with most models, optional for the MTPX Plus 128) and the Auto-calibration utility
within the Matrix Switchers Control Program as follows:
NOTE: To manually set the input level/peaking, see “ Manual calibration .”
1. Disconnect the power and RJ-45 cables at the MTP transmitter connected to the input
to be adjusted.
2. Connect the two cables to the MTP signal generator.
3. If the input cable between the transmitter and the MTPX Plus is longer than 300 feet
(91.4 m), place the Pre-Peak switch on the MTP signal generator to on (see figure 72).

Figure 72. MTP Signal Generator
NOTE: The MTP signal generator does not work on cable lengths over 400 feet
(120 m). Set the level/peaking to its maximum value of 255.
4. In the Matrix Switchers Control Program, click Tools > MTPX Picture settings to
open the MTPX Picture Settings window (see figure 66 on page 115).
