Vancouver BC - Radial Engineering Ltd. is pleased to announce a revised version of the EXTC 500 series module. The EXTC is a unique device that 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. This allows the more creative engineer to incorporate an unlimited range of guitar effects into his or her production with an efficient and easy to use device.

Designed to fit inside both the traditional API style 500 series Lunchbox frames and the more advanced Radial Workhorse, the EXTC begins with a frame mounted XLR input connector where it receives the line level signal from the recording system. The signal is then unbalanced and converted to high impedance where guitar effects pedals can be inserted as desired using the ¼” jacks. These are front mounted for easy access. The latest version 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 precise signal management and this is augmented with a mix/blend function that allows the original tone to be mixed in for the perfect wet-dry balance. Since guitar pedals can often reverse the signal phase, the EXTC incorporates a handy 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 the engineer with a solid signal to feed the recorder using the balanced XLR output or via the Workhorse master section. Both the XLR and ¼” TRS connectors are supported.

According to Radial president Peter Janis: “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.”

When used with the Workhorse, the Omniport™ is designated as a TRS send & receive to allow the EXTC to be normalled to a standard patchbay. This 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. This allows multiple signal paths to be used at once further expanding the creative palette.

The Radial EXTC is without a doubt one of the most innovative yet comprehensive effect manipulating devices ever made. Be prepared for wild & wonderful! The EXTC retails for $300 US and is now shipping.
