How are the effects sends used?

Whether the effect (or in series mode, both effects
together) is used as a loop or an insert depends on the
source selected for the effect inputs.
Aux 1 through 6 When these are selected as
effect input sources, the effect is placed in a loop.
The effect output with this setting is assigned to a
channel using the I/O screens (see “Signal sources”
on page 36 of the main manual).
If a channel has already been assigned to take its
input from an internal effect, this channel is shown
on the OUT section of the screen when the loop
assignment is made and is shown as Chxx (xx = 1
through 32). If no channel has been assigned, the dis-play
shows —. If more than one channel has been
assigned as a return, the display shows ****.
Aux 1 through Aux 6 insert When these are
selected as effect input sources (AUXx INS SEND), the
effect becomes an insert-type effect.
This insert is made post aux send fader.
The outputs of the effect are automatically assigned
to the appropriate aux insert returns and shown as
AUX INS RETURN.
Buss 1 through buss 8 insert When these are
selected as effect input sources (BUSSx INS SEND), the
effect becomes an insert-type effect.
This insert is made post buss level fader.
The outputs of the effect are automatically assigned
to the appropriate buss insert returns and shown as
BUSS INS RETURN.
Stereo L, R insert When these are selected as
effect input sources (ST-L PRE SEND and ST-R PRE
SEND), the effect becomes an insert-type effect.
This insert is made pre stereo master fader.
The outputs are automatically assigned to the stereo
insert returns are shown as ST-L PRE RETURN and ST-R
PRE RETURN.
Assignable inserts 1 through 4 When these
are selected as effect input sources (ASGN INSx SEND),
the effect becomes an insert-type effect.
For these to be effective, the assignable send/returns
must be set to be inserts, not send/return loops (see
“Assignable sends and returns” on page 43 of the
main manual). If they have been set to send/return
loops, a popup message appears informing you of the
fact.
Note that when an assignment is made to these
inserts, the corresponding physical 1/4″ jacks are no
longer available (these settings override the physical
jack insert assignments).
The outputs from the effects are sent to the assign-able
insert return. This is shown in the output assign-ment
section of the effect as ASGN INSx RTN CH y if a
channel assignment has been made, or ASGN INSx RTN
— if no assignment has been made.
Effect 1-2 series
When the two effects units are selected to act in
series, with effect 1 feeding effect 2, although both
effect 1 and effect 2 are shown on the screen, only the
inputs to effect 1 may be set.
The output(s) from effect 1 are automatically routed
to the input(s) of effect 2.
If the source of effect 1 is an aux send, the effect 2
output is assigned to a channel (set using the I/O
screen).
If the source of effect 1 is an insert, the output of
effect 2 defaults to the insert return as shown in the
output assignment section of effect 2.
The outputs from effect 1 are shown as EFFECT2 IN L
and EFFECT2 IN R, and the inputs to effect 2 are shown
as EFFECT1 OUT L and EFFECT1 OUT R (if effect 2 is a
dual-channel effect).
If channel 2 is set to output only a single channel, the
single output from effect 1 is labeled as EFFECT2 IN L
and if there is a single input to effect 2, this is labeled
EFFECT1 OUT L.
