Important information on Patch Cables:

All CMS products use high quality Switchcraft input and output jacks. Other industry names for these jacks are “Tini-Jax” or .141” miniature phone jacks. The jacks are the exact same high quality, American made jacks that were used in the original ARP 2600, ARP 1601 Sequencer and ARP 2500. Buchla equipment also uses Tini Jax. We had to make a choice between the cheaply made, standard Euro Rack 3.5mm connector and the much more robust American made Tini-Jax version. Being the current popular service center for all ARP instruments made the choice an obvious one.These jacks and plugs are far superior in materials and construction than standard Euro Rack jacks and plugs. These American made jacks and plugs will last a lifetime.

Connecting standard Euro Rack 3.5mm cables into our jacks works fine in most cases.

As it was with the original ARP 2500, the use of cables equipped with Switchcraft Tini Plugs is highly recommended.

Making cables is very easy

We have put together a detailed Patch Cord Assembly Guide, with step by step instructions, photos, part numbers and part sources.
