NETWORKING MULTIPLE MIXERS
If additional inputs are needed, more SCM810 mixers (as many as 50) can be “linked” using supplied link cables. Such a configuration can provide up to 400 microphone inputs.
To link multiple mixers, connect the LINK OUT of the first mixer to the LINK IN of the next mixer, and so on (see Figure 8). Leave the LINK IN jack of the first mixer and the LINK OUT jack of the last mixer unconnected.
REMARQUE : Ces jacks sont conçus pour le jumelage des mélangeurs uniquement et non pas pour les entrées ou sorties audio (se reporter à la figure 5).

In a linked system, the Aux input of any mixer appears at each linked mix- er's output. See Internal Modifications to defeat the linking of Aux signals.
IMPORTANT: When using the logic terminals on linked mixers, connect the LOGIC GROUND terminals of each unit together. Switching clicks may re- sult if this is not done.
GLOBAL/LOCAL FUNCTIONS |
|
|
|
The Global/Local switch selects which input channels appear at that linked |
|
|
|
mixer's output. Set to the Global position, all input channels appear at that |
|
|
|
mixer's output. Set to the Local position, only its own eight input channels |
|
|
|
appear at that mixer's output. The Master level control, in any mode, only |
| SCM810 “C” (GLOBAL) | RECORDER |
controls the level of its own output. |
| ||
The Master level control is independent of the Global/Local switch. The out- |
|
|
|
put level of each mixer is affected only by its own Master control. All auto- | LINK | SCM810 “A” (LOCAL) |
|
matic functions (such as Last Mic |

all linked mixers and are not affected by the Global/Local switch. |

An example of the possibilities of this setup is shown in Figure 9 Here two |
|
| |

SCM810s are set to Local, and the resulting sound distribution provides |

local sound reinforcement while avoiding feedback. This is a simple |

LINK CABLES
Additional link cables are available as Shure Part No. 95A1143 (305 mm- 12 in.). Longer cables in a variety of lengths are available from Apple Com- puter as computer printer
connections; they are variously referred to by Apple as “shielded serial cable with two mini
