Introduction
LS9-16/32 Owner’s Manual
The names of the LAYER section keys differ between the LS9-16 and LS9-32.
●LS9-16 ●LS9-32
In conjunction with this difference, there are also differences in the numbering of the channel modules on the panel and the
channels that are assigned to each fader layer.
The LS9 provides the following input channels and output channels.

■Input channels • • • • • • • • • • • • • • • • •

This section processes input signals and sends them to
various buses (STEREO, MONO, MIX). The LS9 has the
following two types of input channel.
●INPUT channels 1–32 {1–64}
These channels process monaural signals. In the initial
state, the input signals from the rear panel INPUT jacks
and the input channels of the slot(s) are assigned to these
channels.
●ST IN channels 1–4
These channels process stereo signals. In the initial state,
the outputs of virtual racks 5–8 are assigned to these chan-
nels.
Signal assignments to the input channels (input patching)
can be changed as desired.

■Output channels • • • • • • • • • • • • • • • •

This section mixes the signals sent from input channels
etc., and sends them to the corresponding output ports or
output buses.
There are three types of output channel, as follows.
●MIX channels 1–16
These channels process the signals sent from input chan-
nels to the MIX buses, and send them from the output
ports. These are used mainly to send signals to the monitor
system or to external effects.
The signals of MIX channels 1–16 can also be sent to the
STEREO bus, MONO bus, or MATRIX buses.
When the LS9 is in the initial state, these are assigned to
the OMNI OUT jacks or the output channels of the slot(s).
●MATRIX channels 1–8
These channels process the signals that are sent from MIX
channels, STEREO channels, and MONO channel to the
MATRIX buses, and send them from the output ports.
Using the STEREO and MONO buses, different combina-
tions of signals and mix balances can be sent out from the
console.
●STEREO channel / MONO channel
These channels process the signals that are sent from the input channels or MIX channels, and send them to the cor-responding output port. These channels are used as the main stereo output and monaural output.The STEREO channel and MONO channel can be used either to output independent signals, or for three-channel L/C/R playback.When the
LS9
is in the initial state, the STEREO channel is assigned to OMNI OUT jacks 15/16 {31/32} and to the 2TR OUT DIGITAL jack.Signal assignments to the output channels (output patch-ing) can be changed as desired.

• In this owner’s manual, whenever there is a difference between the LS9-16 model and the LS9-32 model, specifica-
tions that apply only to the LS9-32 model are enclosed in curly brackets { } (e.g., INPUT jacks 1–16 {1–32}).
• When the specifications are common to both models, the manual refers simply to the LS9.
