Allen & Heath 25 WZ 4 14:4:2 User Guide
Aux pre/post insert / EQ Factory default for the
mono channel pre-fade auxes is pre-insert, pre-EQ. This is
popular with many users mixing monitors from FOH. It pre-
vents the channel EQ and inserted compressors affecting the
monitor mix. Move the jumper from A to B to change this to
post-insert, post-EQ if preferred. Note that auxes are always
post-mute.
Direct output source Factory default is pre-fader.
This is common for live recording to multitrack. The live mix
fader movements do not affect the recording. Move the jump-
er from C to D to change to post-fade. Post-fade is appropri-
ate when using the output as a direct channel effects send.
Channel Aux pre/post settings Factory default is
Aux 1-4 = switched, Aux 5-6 = switched. You can change
these settings for different combinations of pre/post or
switched auxes by cutting and re-soldering the links. Refer to
the system block diagram to explore the possibilities. Make
sure you set all mono and stereo channels the same. We rec-
ommend you only change these settings if absolutely necessary.
Solder Options: Cut tracks with a sharp knife and ensure that any
cuts don't extend beyond the marked area. Add a solder blob to con-
nect the adjoining pads. If you have any doubts about this procedure
please contact Allen & Heath and we will put you in touch with your
nearest service centre.
Stereo Channel Aux pre/post settings Factory
default is Aux 1&2 = switched, Aux 3&4 = switched, Aux 5&6 =
switched. Configure as mono channel but connections are using jump-
ers instead of solder links.
Stereo/Mono aux source The stereo channels can
feed the auxes with a mono sum of L+R, or be configured so
that L feeds the odd numbered auxes, and R the even. This is
preferred when using odd/even auxes as stereo pairs. Factory
default is the mono setting.
Talkback mic +48V The factory default is +48V phan-
tom power turned on for the front panel talkback mic XLR
input. The option jumper is behind the TB mic XLR on the L
Master board. If you prefer, phantom power can be disabled
by repositioning the jumper to the GND position.
Note that phantom power should not harm non-powered dy-
namic microphones as long as balanced connections are used.
WARNING: Do not connect unbalanced
sources or cables to inputs with phantom power select-
ed. To avoid loud clicks do not press the TALK switch
when plugging or unplugging the talkback microphone.
