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:

NFor all of the settings in this section (with the exception of the transmitter’s Pre-Peak switch in step 1), see the MTPX Pictures settings and MTPX configuration settings menu items in “Tools menu”, on page 5-19.

These settings can also be made using SIS commands or the built-in HTML pages. See chapter 4, “Programmer’s Guide” and chapter 6, “HTML Operation”.

NUnless 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', turn the transmitter’s Pre-Peak switch on. For shorter cables, turn the switch off.

MTPX level/peaking setting

The simplest and surest way to set the input level/peaking is to use the included MTP signal generator and the Auto-calibration utility within the Matrix Switchers Control Program as follows:

NTo manually set the input level/peaking, proceed to step 8.

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
	300' (90 m), place the MTP signal generator’s Pre-Peak switch on (figure 5-20).

4.	In the Matrix Switchers Control Program, click Tools > MTPX Picture settings
	to open the MTPX Picture Settings window (figure 5-16on page 5-20).
5.	Click the Auto-Calibrate Level/Peaking button.
	After a few moments, the program reports whether or not the

calibration succeeded and the original and new settings for the input Pre-Peaking adjustment.
