Using cascade connections Using cascade connections By cascade-connecting two or more LS9 consoles or an LS9 with an external mixer (such as the Yamaha M7CL) you can share the buses. For example this is convenient when you want to use an external mixer to increase the number of inputs. If you are cascading two LS9 consoles, you can use the "Cascade Link" function to link cue operations, scene recall/store operations, and fader layer selections. In this case, you can operate the two LS9 consoles as if they were a single mixer. Here we will explain cascade connections and operation, using an example in which two LS9 consoles are cascade-connected. To cascade two LS9 consoles, 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 one sixteen-channel digital I/O card for each console are installed in the cascade slave LS9 and in the cascade master LS9, and the DIGITAL OUT jacks of the sending unit connected to the DIGITAL IN jacks of the receiving unit. Digital audio signal Audio signals of unit A Digital I/O card Audio signals of A + B Digital I/O card HINT • You can also cascade-connect the LS9 with digital mixers that have a Mini-YGDAI slot, such as the Yamaha M7CL or PM5D. However, this only allows you to cascade the audio signals; linking via control signals is not possible. • 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 from each cascade-slave will increase according to the number of units between it and the cascade-master. LS9 A (Cascade slave) LS9 B (Cascade master) MIDI OUT MIDI IN MIDI OUT MIDI IN Control signals for cascade link In this example, up to sixteen buses chosen from MIX buses 1-16, MATRIX buses 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 LS9. {If you're cascade-connecting two LS9-32 consoles, you will be able to share all buses if you install two 16channel digital I/O cards in each LS9-32 console.} Control signals for the Cascade Link function are transmitted and received via the MIDI IN/OUT connectors. In this type of setup, performing a cue operation, scene recall/store operation, or fader layer selection on either console will cause the same to occur on the other console. When using a cascade connection, you must specify the slot(s)/channels on each LS9 console that will send and receive audio signals. Similarly, in order to use the Cascade Link function, you must specify the port that will transmit and receive control signals, and specify the parameters and events that will be linked. The following pages explain the required settings for cascade connection and the method of operation, separately for the cascade slave and the cascade master. 20 LS9-16/32 Owner's Manual 209 Other functions
