Manufacturer's Description from Radial

  • Add guitar effects pedals to vocals or instruments
  • Create exciting and unique effects as you perform
  • Turn on multiple effects using one footswitch
  • Works with either dynamic or condenser microphones

The Voco-Loco is a foot-controlled effects loop that enables the lead vocalist, sax or trumpet player to incorporate guitar effects pedals into the signal path, just like an electric guitarist adds effects for soloing.

The design begins with a state-of-the-art mic preamp that is designed to accept both a standard dynamic microphone or a condenser by activating the built-in phantom power supply. A great sounding two band EQ with low and high frequency shelving makes it easy to add warmth and shimmer. The signal is then sent to the guitar pedals via a transformer isolated hi-Z effects loop circuit that is equipped with individual send & receive controls to optimize signal-to-noise and reduce distortion. A tone control on the return path lets you smooth the sound of pedals that may be overly bright and the blend control lets you mix the original 'dry' signal with the 'wet' effect to set the perfect mix.

Simply plug your mic into the Voco-Loco via the XLR input, connect your effects pedals using standard ¼" guitar cables, and then send the output from the Voco-Loco to the input on your mixer. Before the song begins, choose which effects you want on and - when you are ready - activate the loop using the right hand footswitch. A second footswitch serves double-duty as either a mute switch to turn off the mic between sets or as a 100% wet effects loop for special situations where you may not want any of the clean signal to pass through.

With the Voco-Loco in your signal chain, you can add delay or reverb, maybe a touch of distortion or even a special effect like a wah-wah to enhance your solo performance. The options are only limited by your imagination and desire to stand out from the crowd!

About Manufacturer

Radial Engineering is a manufacturer and distributor of professional audio equipment, building tools for the working audio and audio-video professional. Radial is located on the Fraser River, just outside Vancouver, British Columbia in the municipality of Port Coquitlam. The company began operations in the fall of 1991 as the Canadian distributor of Mogami cable and Jensen Audio Transformers. In 1992, it became a limited corporation under the JP Cabletek Electronics Ltd. banner. The Radial name was first used on house branded cables and snake systems. The Radial name and logo represents a cross section of quad cable; Radial being round. In 1996 the Radial JDI direct box was launched. This led the way to the Radial JDV and today, over 50 electronic products are now being produced under the Radial, Tonebone and Forest Audio brands. In 2001, the Primacoustic brand was launched to address the growing demand for acoustic products for the burgeoning home recording market and in 2006, the company officially changed its name to Radial Engineering Ltd.
