Mono Input Aux Sends: Pre Fader & Eq Or Pre Fader/Post Eq - Yamaha PM4000 Operating Manual

6.3 Mono Input Aux Sends: Pre Fader
& EQ or Pre Fader/post EQ
Ten slide switches in each input module permit each
of the eight mono auxiliary sends and the two stereo
aux sends to be altered. As shipped, the console is wired
so that if the front-panel aux PRE/OFF/POST switch is
set to PRE position, the aux send is derived ahead of the
the fader and equalizer (but after the high pass filter).
This is useful for stage monitor work, for example,

where the channel EQ for the house may not be desired
for the monitors, yet rumble-reducing filtering is
desirable. On the other hand, suppose that one aux mix
is used for a pre-fader effects send. In this case, it may
be desirable to apply channel EQ to the send. The POST
position would provide EQ, but would also cause the
channel fader to affect the send, which is not desirable.
To solve the problem, the switch for that aux send can
be reset so that the PRE position remains pre-fader, but
is taken after the EQ.
