CGM Link System

Some CGM modules, like the QSC, can efficiently work as stand-alone units. However, they unlock their full potential when connected to other units to build a complex mixing console.

For this purpose, we designed a special set of connecting cables named Link System, which replaces the older Link Cables (now discontinued, but still compatible with newer products).

There are three kinds of cables in the new Link System:

• group-to-channel cable;
• master-to-group cable;
• group-to-group extension.

Here’s how it works.

Linking Groups and Channels

The first step to build a CGM configuration is connecting channels to a group. This connection happens through two special group-to-channel cables with 10-pole IDC sockets: connect the two rows of pin headers on the back with the two pin headers in the same position on the group’s PCB.

The GC sockets are spaced so that they can accept modules up to 18 HP wide. For a better fitting, we recommend folding the cables in a Ω shape.

When connected to a group, all the channels share audio, power, and controls, so it is sufficient to connect to the PSU just one channel of those linked to such group.

The GC Link System comes in three different sizes:

• F-G1C2-LS CGM Link System – 1 Group to 2 Channel Modules
• F-G1C4-LS CGM Link System – 1 Group to 4 Channel Modules
• F-G1C8-LS CGM Link System – 1 Group to 8 Channel Modules

Every group module ships with a 1-group-to-2-channels cable, and it’s ready to be connected to a channel (the channel ships with no cables except for the power ones).

If you plan to connect more than two channels to a group, you may want to purchase a 4- or 8-channel cable separately.

Linking Masters and Groups

There are two cases in which you may need to connect groups and masters: to expand the functionalities of a single group or to mix more groups. There are two Link System parts for this purpose: a strip and its extension, one for each use.

By default, the Masterone ships with a master-to-group cable, allowing you to link a group to it. The master-to-group cable has three IDC connectors: one for the master, one for the group, and one for extending the connection to other groups.

To connect more than one group, you need the group-to-group extension. This cable has two IDC sockets and one IDC plug. Connect the plug to the third MG socket, and you’ll be able to link two more groups to a master. The group-to-group sockets are spaced to accepts group configurations of roughly 72 HP, allowing up to 4 QSCs.

It is possible to chain more GG extensions to one another, such as to add a fourth group or connect groups with larger channel configurations (up to eight QSCs).

The master-to-group cable ships with the Masterone and cannot be purchased separately. The group-to-group extension is sold separately with the following code:
