Optimizing the Video
Most MTP transmitters and the MTP SW6 output have a pre-peaking feature. Set these
features as follows for the best image quality:
1.
2.
Level/Peaking Setting
1.

3.
4.
5.
6.
7.
For inputs from MTP T 15HD products only — If the cable between the MTP
transmitter and the MTP SW6 is > 300 feet, turn the transmitter's Pre-Peak switch on.
For shorter cables, turn the switch off.
For the output — If the cable between the MTP SW6 and the receiver is > 300 feet,
turn the switcher's Pre-Peak switch on. For shorter cables, turn the switch off.
NOTE: Unless the TP cable lengths are changed, these settings should need to be
made only once, during installation.
Connect an oscilloscope (preferred) or a monitor (acceptable) to the switcher's output
via a very short (less than 25 feet [7.5 m]) TP cable and a compatible MTP receiver).
If using an oscilloscope, apply a white ield test pattern to the input to be optimized
via an MTP transmitter.
If using a monitor, apply a grayscale or Color Bars test pattern to the input to be
optimized via an MTP transmitter.
TIP:
The Extron VTG 300 or VTG 400 are recommended to provide the test
pattern.
Select the input to be optimized.
Observe the oscilloscope or the monitor with a critical eye while you adjust the front
panel input level and peaking controls to compensate for signal loss between the
transmitter and the MTP SW6.
If necessary, repeat steps 1 through 4 for each input.
If level/peaking and skew adjustments are available on the connected receiver(s), set
them in accordance with the applicable MTP receiver product manual.
Disconnect the oscilloscope or monitor connected in step 1.
NOTES: • A simpler way to set the input level/peaking is to use the optional
MTP signal generator and the auto calibration function on each input,
available as an SIS command. See the
SIS command.

• The auto calibration function compensates for signal losses on the
inputs only. Compensate for signal losses on the output via the
connected receivers' level and peaking controls.
