For the Workhorse and other 500 Series racks, Radial Engineering released the EXTC 500, a revised version of the EXTC Series module.

The EXTC 500 takes a balanced signal and converts it to a guitar level effects loop and then re-converts it back to a balanced level for processing -- a quick, efficient process that allows you to incorporate an unlimited range of guitar effects into your productions.

Designed to fit inside both the traditional API-style 500 Series Lunchbox frames as well as the more advanced Radial Workhorse, the EXTC features a frame-mounted XLR input connector where it receives the line level signal from the recording system. According to the manufacturer, the signal is then unbalanced and converted to high impedance where guitar effects pedals can be inserted as desired using the front-mounted 1/4-inch jacks. The latest version, the EXTC 500, features a transformer coupled output to eliminate potential ground loops from causing hum in the recording system.

Individual front panel send and receive controls allow for precise signal management, while a mix / blend function allows the original tone to be mixed in for just the right wet-dry balance. Radial notes that since guitar pedals can often reverse the signal phase, the EXTC incorporates a 180º polarity reverse that flips the input polarity of the pedal chain at the receive jack so that the wet and dry signals work together and play in phase. Once processed, a gain make-up buffer provides you with a solid signal to feed the recorder using the balanced XLR output or via the Workhorse master section. Both the XLR and 1/4-inch TRS connectors are supported.

When used with the Workhorse, the Omniport is designated as a TRS send and receive to allow the EXTC to be normalled to a standard patchbay. This process allows both standard studio effects and guitar effects to be combined. The EXTC is now outfitted with a buss driver that feeds the Workhorse mixer, allowing multiple signal paths to be used at once.

Radial Engineering's president Peter Janis exclaims, "The EXTC is way too much fun! One can now incorporate all kinds of effects devices into the recording chain to create esoteric and interesting effects. Just imagine…you can now take a voice track and mix in fuzz, wah or just about any effect to produce different and unique tones that can flatter a track and ultimately help your mix stand out from the pack."

The new EXTC 500 is now shipping for $300 (MSRP). For more details, visit radialeng.com.
