I/O Connector
These balanced 1/4" TRS phone type connectors are the left and right outputs
for the stereo mix bus. The signal present at these jacks is adjusted by the Mix
Master Control [5] on the front panel.
The configuration for the ¼" TRS Mix Output Jacks are as follows:
Tip = High (+)
Ring = Low (-)
Sleeve = Ground

The multi-function I/O connector is used to connect the BB-03 Breakout Box
or link up to two additional X.Sum's.
The pin-outs for the multi-pupose I/O connector are shown below in Figure 5.
Note - All active-balanced output circuits of the X.Sum were designed for
balanced lines and should only be connected to balanced inputs. If
that is not possible and it is necessary to connect to an unbalanced
input, care must be taken not to connect the low (-) terminal to
ground. If the low (-) terminal of these outputs is connected to
ground, the result will be a high level of audio distortion.
