About the internal effects
LS9-16/32 Owner’s Manual

The internal effects of the LS9 can be mounted in racks 5–8. For each mounted effect you can

choose one of 48 effect types, and patch the effect to the output of an output channel or the input

of an input channel, or insert it into a channel.

With the default settings, the signals from MIX channels 13–16 are input to racks 5–8, and output

to ST IN 1–4 (L/R).

To use an internal effect via send/return, assign the output
of a MIX channel etc. to the input of the effect, and assign
the output of the effect to an input channel.
In this case, the corresponding MIX bus is used as a mas-
ter channel for the effect send, and the input channel is
used as an effect return channel.
Alternatively, you can assign the input and output of the
internal effect to the insert-out/in of a desired channel
(except for a ST IN channel), so that the effect is inserted
into that channel.
The internal effects fall into two categories; “STEREO
type” (2-in/2-out) effects that process the L/R channel
input signals independently, and “MIX type” (1-in/2-out)
effects that mix the two channels to monaural before pro-
cessing them.
If signals are assigned to both the L and R inputs of an
effect, the way in which the L/R channels are processed
will depend on whether a Stereo effect type or a Mix
effect type is selected, as follows.
●STEREO type effects
●MIX type effects
If a signal is assigned to only one input of a two-input
effect, it will be processed as mono-in/stereo-out regard-
less of whether a Stereo effect type or Mix effect type is
selected.
About the internal effects
• The internal effects cannot be mounted in racks 1–4.
• Some effect types can be mounted only in rack 5 or 7.
