MTX-986-UTP VIDEO INPUT ADJUSTMENTS
The MTX-986-UTP has the ability to individually boost the high frequencies of each of the eight
video inputs of the UTP ports. This boost is available to compensate for the high frequency roll
off at 3.58 MHz associated with CAT 5 UTP cables. Typically, CAT 5 UTP cables have a slope
roll off of 4dB for every 100 meters of cable. See the drawing below for the location of the
SLOPE switch associated with each video channel. The MTX-986-UTP is shipped with these
switches in the up (off) position. To increase the video input levels into this unit at 3.58 MHz by
4dB (20 IRE), move the desired channel switch to the down (on) position.
MRX-986-UTP VIDEO OUTPUT ADJUSTMENTS
The MRX-986-UTP has the ability to individually increase or decrease each of the eight video
outputs of the UTP ports. See the drawing below for the location of the LEVEL potentiometers
associated with each video channel. The MRX-986-UTP is shipped with these potentiometers in
the midrange position. To increase the video output of this unit to a maximum of 2 volts p-p turn
the desired potentiometer counter clockwise. To decrease the video output of this unit to a
minimum of 0 volts p-p turn the desired potentiometer clockwise.
