Studio 300 Series
EuroRack & EuroSynth System

The Studio 300 series offers the user a flexible solution to their EuroRack/EuroSynth enclosure needs.
Using a small set of building elements the user can build systems from 42HP wide through to 168HP.

The Studio 300 enclosures are 80mm deep (60mm internal module depth) and provide a low-profile design ideal
for where space is critical or a truly portable solution is required.

The Studio 300 can also be used as a lid for all of the Studio Series of enclosures


Rails form the main component of any racking system by providing a mechanical sub-frame for securing modules
in to your system. 4 Rails are required for each 6U section of subrack and come in the following standard `module opening' widths:- 42HP, 84HP, 126HP and 168HP. Other widths are available on request.

Made from a high-quality aluminium they are irridium plated for improved electrical conductivity
and anodised for a tougher surface finish.

All Rails are pre-tapped to accept M5 bolts making assembly a breeze while offering a secure and rigid assembly.

Tapped Strips

Tapped Strips slide in to a dedicated slot near the front of the rail and are used to accomodate the module fixing screws. The strips are tapped at 1HP (5.08mm/0.2") intervals with 3.0mm holes or optionally 2.5mm holes.

Maximum strip length is 84HP but their design allows them to be butted end-to-end with no loss of the 1HP interval. We also offer 19HP, 42HP and 83HP Tapped Strips allowing the common system widths of 42HP, 84HP, 104HP 126HP and 168HP to be easily accommodated without requiring Tapped Strips being cut.

For those requiring flexibility over the spacing between tapped holes such as when installing modules that do not confirm to the standard defined by Doepfer and as used in our Panther family, we offer Square Rail Nuts. These slide in to the same slot as used by the Tapped Strips and can be positioned anywhere along the length of the rail.
Square Rail Nuts are offered with either M3 or M2.5 tapped holes.


6U 42HP Skins

Our 42HP 6U 300 Skin is a new approach to subrack construction.
Multiple skins are be bolted side-by-side to create wider subracks.
This sub-assembly is then closed off with the addition of 2x 300 Side Panels
and the appropriate length Rails and Tapped Strips.

The Studio 300 will accomodate modules up to a depth of 60mm

Eack Skin is supplied pre-fitted with a series of M4 threaded studs in the base that match our Busboard Carrier Plate.
The plates, which are pre-punched to provide support for our ED7xx family of busboards,
provide a common mounting template for case manufacturers requiring only 4 fixing points in the case.

Fixing Hardware

Assembly of all of our Studio 300 Series is done using bolts making them an easy assembly for everyone.
All the required hardware is supplied with our Studio 300 Series Kits but can also be
supplied loose for those purchasing their own mix of parts.
