Radial Workhorse

8-Slot 500 Series Power Rack with Summing Mixer


About this item



The Radial Workhorse is a modular 500-series rack that combines an extensive patching system with an analog summing mixer to create an incredibly flexible studio environment.

  • 500 series 8 slot rack with 8×2 summing mixer
  • Plenty of current for power hungry modules
  • Dual output headphone buss for monitoring
  • DB25, TRS & XLR I/O for flexible patching

Create Unique Channel Strips

Compatible with all API 500 series modules, the Workhorse provides more power and easier connectivity than a typical rack. Not only is it equipped with a variety of I/O options, but a signal to be routed from one module to the next without cables to easily create channel strips. Compatible EQ and compressor modules can also be stereo linked with the flick of a switch. A special Omniport jack delivers module-specific functionality that can range from an extra output, key input, or effects insert depending on the module. Finally, an external 1600 mA power supply provides enough current to ensure each module is powered correctly.

Mix Outside The Box

Unique to the Workhorse is a built-in summing mixer that allows module outputs to be turned on and off, level matched and panned to a Jensen transformer-coupled stereo output. Multiple Workhorses can be linked in larger mixer setups, and a high-quality headphone output allows for monitoring without latency when tracking.

The Radial Workhorse is designed to be a neutral sounding platform through which various modules can be connected. In other words, the `personality` of the module is meant to shine through. The simplicity of the design is ideally suited for this task as there are no individual channel inserts, effects or equalization circuits. This being said, analog audio equipment should introduce warmth and personality to the clinical world of digital recording. To this end, we have provided two types of outputs: the main output is Jensen transformer coupled to add character and warmth while the monitor output has been optimized for absolute linearity.
