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:

For 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

Operation”.

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', 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:
N
To 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(gure5-16on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.
