Using Cascade Connections - Yamaha CL5 Reference Manual

Using cascade connections

Using multiple CL series consoles, or a CL console and an external mixing console (such as a Yamaha
PM5D) in a cascade connection enable buses to be shared among the devices. This can be convenient
if you want to use an external mixer to increase the number of inputs.
This section explains cascade connections and operation, using an example in which two CL units are
connected in a cascade configuration.
About cascade connections
To cascade two CL series consoles, you must first install digital I/O cards in the appropriate 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 CL unit and in the cascade master CL unit. The DIGITAL OUT jacks
of the sending unit are connected to the DIGITAL IN jacks of the receiving unit.

Digital I/O card
In this example, up to twenty four buses chosen from MIX bus 1–24, 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 CL unit. (If you use three 16-ch digital I/O cards, all buses can be shared among the
devices.)
You must specify bus assignments for each or channel on each CL unit. Separate procedures are
outlined below for the cascade slave and the cascade master.
NOTE
• If you are making a cascade connection between the CL unit and the PM5D, you can use the CL
unit as the cascade slave by setting the PM5D's CASCADE IN PORT SELECT to a slot. However,
only the audio signals 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-connected, but the signal delay at
the cascade slave will increase in accordance with the number of units from the cascade master.

Operations on a cascade slave CL unit
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
CASCADE button to open the CASCADE popup window.
This window enables you to select an I/O port used for cascade connections. The window consists
of two pages: The CASCADE IN PATCH page and the CASCADE OUT PATCH page. To switch
pages, press the corresponding tab at the bottom of the window.
3.
Press 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.
1
OUT PATCH buttons (CASCADE OUT PATCH section)
Enable you to select the output port for cascade connections for each of MIX 1–24, MATRIX 1–
8, STEREO L/R, MONO, and CUE L/R buses. Press the button to open the PORT SELECT popup
window, in which you can select a port.
2
CASCADE LINK MODE buttons
Specify whether cue operations or scene store/recall operations will be linked on the CL series
consoles in a cascade connection.
3
CASCADE COMM PORT buttons
Specify the communication port used for transmitting and receiving link information when cue
operations or scene store/recall operations are linked on the CL series consoles in a cascade
connection.
