Isopatch Bantam

The Isopatch Bantam is our longest running and most popular patch panel.  With two rows of 48 bantam jacks and normalising programmable on every channel, it’s the industry-standard for pro-audio patching.  Two horizontal PCBs and a steel front panel assembly make this a solid and reliable classic that’s equally at home in a project rack or fully professional studio.

Industry standard, studio quality

The Signex Isopatch Bantam is based on the same design that made the original Isopatch so popular, but uses the 4.4mm ‘Bantam’ Jack widely accepted in professional studios.

The twin Bantam Jack used in the Isopatch Bantam is of an enclosed design that helps to keep out the contaminants that shorten contact life, with spacing to accept twin ‘stereo’ plugs.

Contacts are silver or gold-plated phosphor-bronze.


  • Two rows of 48 Bantam Jacks in 1U of rack space
  • Enclosed twin Jack design keeps out dust and dirt
  • Direct solder or 25 way D-sub rear termination
  • 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
  • Silver and Gold contact versions available
  • PCB parallel points for every Jack

Hand-built, quality construction

All components are mounted on two horizontal printed circuit boards (PCBs) which makes the Isopatch Bantam very solid and gives full access to most of the circuitry including parallel points and the special ‘program pads’ for normalising. The use of flexible jumper cables between top and bottom PCBs means
that the Isopatch Bantam can be opened up for servicing if needed.

Easy to install, built for simplicity

Unlike conventional patch panels, the Isopatch offers half or full normalising on every channel by simply soldering across special ‘program pads’ on the top PCB – No need for tedious hard-wiring. In fact, if the Isopatch Bantam is already installed, you don’t even have to unplug the rear connectors.

Multiple termination and patching options

The PCB offers 25 way D-sub connectors wired to the Tascam 38/88 pattern, so that wiring looms can be made up separately, then just plugged in on site. Alternatively, direct solder versions are available with on board cable-tie points for every channel. The Isopatch bantam can be used for most types of audio signal including mono, stereo, balanced and unbalanced lines. It can also be used for mixer insert points without the need for special ‘splitter’ leads.
