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:
N For all of the settings in this section (with the exception of the transmitter's
N Unless the TP cables are changed, these adjustments should need to be made
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.

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.
