Figure 3.2 describes the cable required to interconnect the Quartet frames. As
shown in this diagram, #18 AWG wires are connected between the two terminal
strips (shipped with the frames) in a pin-to-pin fashion. Make sure the terminal
screws are secured tightly. Figure 3.3 provides the DC connector’s pinout viewed
from the rear panel of a Quartet frame.
