The ADDAC213 Bridge acts as a simple one-cable bridge system between different areas of a case or different cases. The ADDAC213A modules can send & receive 8 CV or audio signals between your cases on their own, but can also be expanded with the ADDAC213Bs to bridge two cases for up to 24 signals at the same time. The 213Bs can also be used independently in a single case. Both The 213As and 213Bs are sold as a pair of modules.


Use a pair of ADDAC213As to send & receive 8 CV or audio signals between distant points in your case, between two separate cases, or between your case and a friend’s case.

 Less clutter, less spaghetti, faster connection! 

There’s nothing better than being able to connect that controller skiff with just one cable to your main system – whether you’re at a gig, in the studio or when jamming with a friend.

Expansion by the ADDAC213Bs:
Each ADDAC213A module can be connected through a ribbon cable connection on its backside with up to two ADDAC213Bs. Each ADDAC213B module expands the channels options of the ADDAC213A by adding 8 more channels.

 With two 2 ADDAC213Bs connected to each ADDAC213A module, you’ll have a total of 24 channels going between your cases with a simple one-cable bridge.

Between the ADDAC213A pair and the ADDAC213B, your cases never looked so elegantly connected together!

The ADDAC213As are always sold as a pair of 2 modules and each module can be installed in normal position or at 180 degrees.

The ADDAC213B’s are a pair of passive modules used to send & receive 8 CV or audio signals between different points inside the same case, or as an expansion to the main pair of ADDAC213A Bridge modules.

Standalone use

Two ADDAC213B modules are connected to each other with the use of a single ribbon cable and then used inside a case to carry signals between distant points without the need for many long patch cables. Less clutter, less spaghetti, more space of your fingers on those knobs! ADDAC213Bs always come in pairs. A single pair can send & receive up to 8 CV or audio signals between different points in your case at the same time. The modules can be installed in normal position or a 180 degree position to fit any need. Do you have modules that you often use together in different areas of your case? Would you prefer that each row’s cables don’t mingle with cables from other rows? Grab yourself a pair of ADDAC213Bs.

As an Expansion to an ADDAC213A:
Each ADDAC213B connected to the backside of an ADDAC213A adds 8 more channels to the main bridging functionality of the ADDAC213A.
Up to 2 ADDAC213B can be connected to an ADDAC213A module, expanding the bridging between two difference cases to a total of 24 channels.
