CGM

Creative Mixer Series

cgm acronym for Channel-Group-Master.

The CGM Creative Mixer is a modular mixing solution for Eurorack systems. It breaks down the main parts of a classic mixer console into three module families (channels, groups, and masters) and adds plenty of CV modulations to them.

It is an ever-growing mixing ecosystem designed to suit every mixing situation.

The CGM works by connecting its modules through IDC sockets on their PCBs, but some modules work both as stand-alone components and as parts of larger setups.

The various modules share audio, power, and controls through the IDC cables on the back.

You can connect up to eight members of the channel family to a group and up to four groups to a master, for a total of 128 channels in the current largest configuration.

Professional Audio Treatment and Analog Saturation

We designed the CGM to bring a professional audio console to the Eurorack world.

It guarantees excellent signal treatment, plenty of headroom, and a warm, musical saturation on every module (yes, even on the master!).

Flexibility

Thanks to its modular architecture, you can combine the CGM modules in many configurations, from smaller, compact cases to behemoth-like studio systems.

CV Modulations

The body and soul of modular synthesizers is control voltage, so we equipped the CGM with a wide array of CV inputs.

In this way, you can animate your compositions and treat your mixer as an actual musical instrument.

Channel Family

With the channel modules, your Eurorack sound enters the CGM circuit and begins its road to the outside world.

From here, you can define the input gain, the volume in the mix, the effect sends, and the pan level.

According to the module, you can voltage-control some or all of these parameters.

High-standard VCAs with plenty of headroom guarantee crystalline sound treatment, but you can push the input gain to the limit and obtain a smooth and warm saturation.

As of today, there are two members in the channel family.

Group Family

The group is the first section of the CGM that mixes the signals and makes some of the channels’ functionalities effective. It then routes the channels’ sum to the Master module (if present).

With a group, you can mix up to eight channels (of either kind), take advantage of the Safe Solo function, and handle their effect routing through two mono sends and two stereo returns.

You can easily use the group as your latest stage in the audio chain in smaller setups thanks to its Group Outputs.

Master Family

The master section is the gateway to the outside world.

With a master module, you can mix up to four groups. Since every group can mix up to eight channel modules, a master can handle 32 channels. If such channels are QSCs, the largest possible configuration is a mixer of 128 total channels.

Thanks to its headphones output, the master allows you to take advantage of the pre-fader listening function and use the channels and groups to their full potential.

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

By default, the new channel modules ship with the first Link System, so you can connect two channels to a group. Should you need more channels, you can purchase the other configurations separately.

Older Group-to-Channel Link Cables

Back when the channels were all 6 HP wide, there were eight kinds of Link cables, connecting a group to 1, 2, 3, 4, 5, 6, 7, and 8 Cs respectively. The socket spacing was tailored to 6 HP, so the introduction of the QSC made a redesign necessary.
If you still have some older Link cables, you can use them easily with newer products, even if some plugs will inevitably end up being unused.

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:

  • F-G2GX-LS CGM Link System – Group to Group Extension

Older Master-to-Group Link Cables

The previous way of connecting groups and masters, part of the Link Cables, consisted of four configurations that allowed you to connect a master to 1, 2, 3, or 4 groups respectively.

The sockets’ spacing could fit up to 8 mono channels per new group.

The M module used to ship with a link cable to one group, and the G module with link cables to four channels.

Anyway, both the older Link Cables and the new Link System follow the same logic and are completely swappable. If you have older cables, feel free to use them with the new CGM modules, and with the new Extension, if you follow the connection rules.

CGM_FAQ

You always need at least one group if you plan to incorporate a master module in your setup. It is not possible to connect any channel module directly to a master module.

The CGM is designed to let you connect up to eight channels (C or QSC) to one group (G), but there is no way of connecting the same channels to two or more groups.

Yes, to take advantage of the Master module’s functions (PFL, headphones, final gain stage), you need at least one group.

We designed the group (G) module together with the classic mono channel (C), which is 6HP wide. After the QSC release, we developed a new Link System with wider plugs that allow you to connect more QSCs in a row.

If you need to connect more QSCs, check your local shop for cable availability!

If you just need to connect a QSC, the classic group-to-channel cable works great, too.

If you experience an abnormal panning on the CGM, check your case’s power supply and your system’s overall power consumption. We experienced that the CGM system sometimes has trouble working in a system close to its maximum Ampère output. An unbalanced power supply may cause the audio to be louder on one channel than on the other.

Try staying below 80% of the total amperage or switch to a more powerful PSU to solve this issue.

We don’t sell directly. Please check our Reseller List to choose your favorite shop!

In Europe, we sell exclusively through our distributor: we do not have access to the individual shops’ orders or stocks.

In the rest of the world, we sell directly to the shops, but even in that case, there’s no way for us to know whether the modules that we’re restocking are sold, available, or reserved for another customer.

We restock every module at least once over a year: we focus on a module’s batch at a time, then we move on to the next one, and so on.

The Mute button closes the first VCA of the channel, thus preventing the sound from being routed through all the other VCAs (FX sends, pan, main fader).

The Solo in Place button isolates some channels and mutes the others. However, the mute function it performs is different since it affects the channel after the fader: the sound will still be routed to any pre-fader VCA such as Direct Output and FX Sends (when set to Pre-Fader Mode).

In other words, the Mute button works pre-fader, while the Solo in Place works post-fader.
