Speck Electronics X.Sum - Manual (Page 21)

Chapter 3 Operation Section 17
This modular plug connects the BB-03 Breakout Box to the multifunction I/O
connector [13] on the rear panel of the X.Sum.
These balanced ¼" TRS jacks are the left and right outputs of the Mix-B bus.
The signal present at these jacks is adjusted by the Monitor [7] control on the
front panel.
Another function of the breakout box connector will also let you connect your
own external preamps to the X.Sum should you want to experiment with a
more "colored" sound. The Mix-A (pre-fader) output jacks on the breakout
box bypass the output circuits and the master level control of the Xsum so you
can connect a pair of external preamps should you want to experiment with
"character" sounds.
The DC power cable that comes from the power supply connects to this 8 pin
circular connector. This connector and its respective plug is keyed so they will
only fit in one direction. For power supply installation instructions, refer to
the Interface & Setup Section in this manual.
The following connector illustration and chart as shown in figure 6 represents
the DC voltages to the 8 pin circular connector required to power the X.Sum.
