M7CL Owner’s Manual
Introduction
1
The sixteen MIX buses provided on the M7CL can be assigned either as VARI or FIXED types in
pairs of adjacent odd-numbered/even-numbered buses ( → p. 234). Each type has the following
characteristics.
● VARI
This type allows the send level of the signal sent from the
input channels to the MIX bus to be varied. The point at
which the signal is sent from the input channel to a VARI
type MIX bus can be chosen from before the EQ, before
the fader, or after the [ON] key (after the fader). This type
is used mainly for sending the signal to a monitor system
or external effect.
● FIXED
With this type, the send level of the signal sent from the
input channels to the MIX bus is fixed to unity (0 dB). The
signal sent from an input channel to a FIXED type MIX
bus is taken from immediately after the [ON] key (after
the fader). This type is used mainly when you want to dis-
tribute signals to an external device at the same mix bal-
ance as the STEREO/MONO buses.
“Word clock” refers to the clock that provides the basis of timing for digital audio signal process-
ing.
Normally, one device transmits a reference word clock signal, and the other devices receive this
word clock signal and synchronize to it.
In order to transmit or receive digital audio signals to or from an external device via a digital I/O
card installed in a slot of the M7CL or EtherSound jacks of the M7CL-48ES. The word clock must
be synchronized between the devices. Be aware that if the word clock is not synchronized, the
signal will not be sent correctly, or there may be unpleasant noise. (For details on synchronizing
the M7CL’s word clock with an external device → p. 230).
In this manual, switch-type controls on the panel are called “keys.” Of the control knobs on the
panel, those that turn from a minimum value to a maximum value are called “knobs,” while those
that turn endlessly are called “encoders.”
Controls located on the panel are enclosed in square
brackets [ ] (e.g., [CUE] key) in order to distinguish them
from the virtual buttons and knobs displayed in the screen.
For some controls, the name of the section is given before
the [ ] (e.g., SCENE MEMORY [STORE] key).
Whenever there is a difference between the M7CL-32
model and the M7CL-48 model, specifications that apply
only to the M7CL-48 model are enclosed in curly brackets
{ } (e.g., INPUT jacks 1–32 {1–48}).
