A timeless classic

The original Isopatch was introduced in 1985 and became an instant success.  Now, nearly 40 years on, it’s still be one of our best-sellers.

At the front, the fully-enclosed connector design helps to keep out the contaminants that shorten contact life.  A smart nickel-plated ring gives an improved ‘feel’ when plugging/unplugging and our neat slide-in labeling system makes designation of signals easy and neat.  All in all, one of the coolest looking patch panels you’ll see in any studio!

  • Two rows of 24 type A Jacks in 1U of rack space
  • New enclosed Jack design keeps out dust and dirt
  • Jack, RCA phono or direct solder rear connections
  • Half and full normalising available on all channels
  • Suitable for balanced/unbalanced and stereo signals
  • Lacing Bar Kit available for extra rear cable support
  • Neat and easy slide-in strips for socket designation
  • Suitable for insert points without special leads
  • Gold contact versions also available
  • PCB parallel points for every Jack

Lateral board design

The Isopatch has all its connectors mounted on two horizontal printed circuit boards (PCBs).  This type of design not only eliminates most of the wiring, but also adds rigidity so there’s no flexing of the panel in use.  Flexible jumper cables carry normalled signals between top and bottom boards and allow access for servicing if needed.

Flexible normalling

The Isopatch is supplied with all sockets isolated, but Half or Full normalling is available on every channel by simply soldering across special ‘program pads’ on the top PCB – No special tools are needed and there’s nothing to take apart. In fact, if the Isopatch is already installed, you don’t even have to unplug the rear connectors – Just a few blobs of solder and it’s done.

Contact and rear termination options

The Isopatch can be used for most types of audio signal including mono, stereo, balanced and unbalanced lines.  The standard version comes with silver-plated contacts, but gold-plated versions are also available.  Rear connections are via board-mounted D-sub, Jack, or direct solder termination.
