Optimizing the Video
Each TP input has a level and peaking adjustment. Most MTP transmitters and each
MTPX Plus TP output has 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 105.
• These settings can also be made using SIS commands or the built-in HTML
pages (see the “ Programming Guide ” and “ HTML Operation ” sections).
• 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 200 feet (61.0 m) or longer, turn the Pre-Peak switch on the
transmitter to on. For shorter cables, turn the switch off.
MTPX Level and Peaking Setting
Auto calibration
The simplest and surest way to set the input level and peaking is to use the included MTP
signal generator and the auto-calibration utility within the Matrix Switchers Control Program
as follows:
NOTE: To manually set the input level and 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 included MTP signal generator.
3. If the input cable between the transmitter and the MTPX Plus is longer than 200 feet
(61.0 m), place the Pre-Peak switch on the MTP signal generator to on (see figure 54).

NOTE: The MTP Signal Generator does not work on cable lengths over 400 feet
(120 m). Set the level and 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 46 on page 106).
