Speck Electronics MicPre 5.0 - Manual (Page 29)

The signal flow diagram below (Figure 12) shows two separate
signal paths with the "mic to pre out" shown in a dashed line and
the "line in to mix out" as a solid bold line.
These "Active-Balanced" TRS jacks are the left and right outputs
for the mix section. The signal present at these jacks are adjusted
by the mix level and pan controls on the front panel.
The mix outputs are available for interface to the input of an
external console, HDR, DAW, etc. The mix out jacks are wired as
shown below in Figure 13.
Do not use the mix out jacks with an unbalanced input. When
wiring unbalanced cables and connectors, care must be taken not
to connect the low terminal (ring) to ground.
Any unbalanced ¼" plug interfaced to this jack should be wired
according to the diagram shown below in Figure 14.
