Audio and data connectors are available in a variety of configurations. Modules are available in groups of eight channels and can be installed in any order. Modules that feature DB25 connectors adhere to industry-standard pinout wiring conventions.
The versatile PB28 system is the perfect addition to any audio facility. Industry standard configurations make the PB28 modules easy to install in any context from concert touring stage racks to post production and studio patch bays. Bring Cat-5 connections to a central location, make touring racks easier to patch together, or configure stage boxes for a digital snake with ease.

The basis of the PB28 system is the PB28 Patch Panel, a blank, 1U-high unit that accepts up to two PB28 Series modules. Patch panels can be user-installed using only a screwdriver. Two modules can be installed per PB28 Patch Panel.
