unbalanced signals when required.
WARNING: Do not connect unbalanced sources or cables to
the XLR input when 48V phantom power is selected. To avoid loud
clicks always turn the channel off by pressing MUTE when switching
+48V on or off, and when plugging or unplugging cables.

WZ 16:2 has two stereo return inputs ST1 (balanced) and ST2

connect the TRS ring to ground for working with balanced sources. The L

A single 3-pole TRS jack carries the unbalanced insert signal.

DIRECT OUTPUT
an impedance balanced TRS jack. It is a line level signal operating at
0dBu. The source is set using an internal option jumper for each channel.
The factory default setting is pre-fade (following the pre/post-EQ setting).
This may be changed to post-fade if preferred.
The direct outputs provide a useful source for multitrack recording. Many
users prefer pre-fade sends for this application so that the live show fader
movements do not affect the recording which can be mixed later. Another
application is channel effects sends. For example, a reverb unit may be
dedicated to work with the lead vocalist channel only. Using a post-fade
direct output instead of an aux send frees up that aux mix for other
purposes.
