At this point in time we do not offer or
sell cabinets or power supplies for our eurorack 2500 modules.
We can certify that any of the Doepfer A100
cabinets will work very well with our modules.
Our modules are 14HP wide.
84 HP and 168HP cabinets work very well with
our modules.
19 inch rack mount cabinets:
We recommend the Doepfer A100G6.
This cabinet is 84HP so it will accommodate
12 of our eurorack 2500 modules.
Less expensive, wooden 84 HP cabinets are:
A-100LC3 - single row of 6 modules.
A-100LC6 - two rows of 6 modules, 12 modules
total.
A-100LC9 - three rows of 6 modules, 18
modules total.

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 will work 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.
