Figure 4 — Setting the gain/peaking jumpers
2. Locate the gain/peaking jumpers on the wider of the two circuit boards
attached to the back of the faceplate (figure 4). J16 controls blue
gain/peaking, J17 controls red, and J18 controls green.
3. Using needlenose pliers to reach and move the jumpers, set the jumpers to
the positions that yield the best image display.
• Use pins 3 and 4 to increase the output signal and add 50%
of the maximum peaking to the signal.
• Use pins 2 and 3 for unity output (0.7 volts, no peaking; the
default).
• Use pins 1 and 2 to increase the output signal and add
100% of the maximum peaking to the signal for very long
cable runs.
4. Reattach the faceplate to the enclosure by reinstalling the screws you
removed in step 1.
Attaching output cables
After the circuit board switches have been set, attach the cables that will be
inaccessible after installation.
Audio output connector
The 3.5 mm, 5-pole captive screw (Phoenix) connector is used
for balanced/unbalanced audio output. Attach the five
wires for audio output of ground, left, and right channels to
the connector; follow the wiring guide shown in figure 5.
Insert the wires into the appropriate openings. Tighten the
screws to fasten the wires.
