Radial Engineering Workhorse - Powerstrip

The Radial Powerstrip is a 3-slot power rack for the popular 500 series, designed to create the ultimate channel strip with 500 milliamps of available current.

The PowerStrip is a three module rackmount power supply designed to bring the fun and excitement of 500 series modular audio to everyone!

Unlike other single space power racks that are limited to two modules, the innovative triple-module design allows you to put together a traditional channel strip, combining a mic preamp with an equalizer and dynamic control using a compressor-limiter all within the confines of a single RU 19" rack. With so many choices of modules available today, this opens the door to creating unique signal paths to allow your music to stand out.

Following the criteria established by the Radial Workhorse, the PowerStrip is 100% backwards compatible with older API modules while being optimized for Radial's expanding range of preamps, processors and routing devices. Construction begins with 14 gauge steel and features dual gold contact EDAC 15-pin connectors for optimal signal transfer. To maximize headroom, the external supply delivers 800mA of current for voltage hungry modules plus a separate 48V phantom tap delivers 10mA of current for microphone preamps. Rear panel connectivity includes standard XLRs for each slot along with ¼" TRS connectors for multing modules, cross patching and parallel processing. Instead of the traditional 'hardwire patch' system employed by others, The PowerStrip employs an innovative feed function that patches modules together in series without the need of cables. And stereo modules no longer need to be soldered to be paired, they can now be sync'd together using a simple switch. The PowerStrip is also equipped with Omniport on each sot. This TRS jack enables the module manufacturer to implement a unique function for a given module such as a key input on a gate.

The PowerStrip makes it easy to assemble a variety of modules to create the ultimate channel strip and the compact single RU design opens the door for use in both studio and concert touring.

    Solid build
    Heavy and solid, this unit is well worth it's price point.
    Internal daisy-chain connection of each module.
    3 modules in a single rack space.
    No power indicator on the front.
    No power switch.
    Inline external power supply.

    If you're looking for a customized "channel strip" in a single rack space - this is the one.

    Radial Powerstrip delivers well again ... with a mod
    This is the second Powerstrip I've purchased. This time I did a couple of things to both units that improved functionality. First, the 'guide plate' inside the unit performs no useful function when using with CAPI mic preamps - all it does is add weight - so I removed it from each unit. Second, having the power LED on the back panel made no sense to me, so I modified both units by mounting the LED through a hole in the front panel (extending wires from the rear circuit board). I am still concerned the units do not deliver the full +/-16 Vdc as per the API 500 series spec (both units deliver only about -14.8 on the negative rail), however the CAPi preamps seem to be operating reliably so far. As always, Studio Economik pricing was good, and delivery was quick.

    Built like a tank, good feature set
    Bought the Radial Powerstrip to hold a CAPI VP26 'kit' microphone preamp. I was a bit surprised when I got the Powerstrip, it is VERY heavy, as the chassis is completely made of thick gauge steel. The unit offers great features in terms of dual inputs and outputs, and switch-enable module interconnections which I don't need at this time, but nice to have. It works great so far, and I plan to add two more modules eventually. Only thing I wish it had was a power switch on the front. And maybe less weight. But it's high quality and good value for the money if you only want to house up to three 500-series modules.
