M7CL Owner’s Manual

Using cascade connections

232

By cascade-connecting two or more M7CL units or an M7CL with an external mixer (such as the
Yamaha PM5D) you can share the buses. For example this is convenient when you want to use
an external mixer to increase the number of inputs.
Here we will explain cascade connections and operation, using an example in which two M7CL
units are cascade-connected.

To cascade two M7CL units, you will install digital I/O
cards in their respective slots, and connect the output ports
of the sending unit (the cascade slave) to the input ports of
the receiving unit (the cascade master).
The following illustration shows an example in which
three eight-channel digital I/O cards for each unit are
installed in the cascade slave M7CL and in the cascade
master M7CL, and the DIGITAL OUT jacks of the send-
ing unit connected to the DIGITAL IN jacks of the receiv-
ing unit.
In this example, up to twenty four buses chosen from MIX
bus 1–16, MATRIX bus 1–8, STEREO bus (L/R),
MONO(C) bus, and CUE bus (L/R) can be shared, and the
mixed signals transmitted from the cascade master M7CL.
(If you use sixteen-channel digital I/O cards, you’ll be
able to share all buses.)
You do not need to make settings on each M7CL to spec-
ify the slot/channel to which each bus is assigned. The
procedure below is given separately for the cascade slave
and the cascade master.

1

In the function access area, press the
SETUP button to access the SETUP screen.

2

In the SYSTEM SETUP field located in the
center of the SETUP screen, press the CAS-
CADE button to open the CASCADE popup
window.

The CASCADE popup window contains the following
items.

1

Port select popup buttons

These buttons access a popup window where you can
select the input/output port for each bus.

BCASCADE IN PATCH/CASCADE OUT
PATCH tabs
These switch between the CASCADE IN PATCH
page and the CASCADE OUT PATCH page.
The CASCADE popup window is divided into two
pages; a CASCADE IN PATCH page where you can
select the input ports for the cascade connection, and a
CASCADE OUT PATCH page where you can select
the output ports. Use the tabs located in the lower left
of the screen to switch between these pages.
3Press the CASCADE OUT PATCH tab to
access the CASCADE OUT PATCH page.
In this screen you can select the slot and output port
that will output each bus.

• If you’re cascade-connecting the M7CL with the PM5D, you can
use the M7CL as the cascade slave if you set the PM5D’s CAS-
CADE IN PORT SELECT to a slot. However, only the audio sig-
nals will be cascaded, and the control signals cannot be linked.
•You can also use an AD/DA card to make cascade connections
with an analog mixer.
• There is no limit to the number of units that can be cascade-con-
nected, but the signal delay at the cascade slave will increase
according to the number of units from the cascade master.
