Radial Voco-Loco

Mic Preamp and Effect Loop

The Voco-Loco is a foot-controlled microphone preamp and effects loop switcher that enables a vocalist or acoustic instrumentalist to incorporate guitar effects pedals into their signal path.

• Add guitar effects pedals to vocal or instrument mics

• Create exciting and unique effects as you perform

• Turn on multiple effects with one footswitch

• Works with dynamic and condenser microphones

Connect any mic to your guitar pedals
The Voco-Loco combines a microphone preamp with a guitar pedal effects loop, allowing a lead vocalist, sax or trumpet player to add guitar pedals to their audio signal path just like an electric guitarist adds effects for soloing. 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. Now with the touch of a footswitch you can add your favorite delay, reverb, distortion or wah-wah to any mic'd up instrument or vocal - the options are only limited by your imagination.

FEATURES

Mute Loop
Used to set the function of the left footswitch to  either Mute or All Wet.

Mic In
Sets the input level of the Voco-Loco’s mic preamp.

Mute / All Wet
Footswitch activates the MUTE or ALL WET function.

Low / High
Dual band shelving EQ is used to add bass to warm up the voice or add sparkle for extra cut.

Send / Receive
Individual send and receive controls let you adjust the level going to the pedals to optimize signal-to-noise and reduce distortion. 

Tone
Lets you tame the sound of the effects return path to soften the harsh tone certain pedals produce. 

Loop Wet / Dry
Primary footswitch turns on or off the effects loop with wet/dry mix engaged.

Mix
Sets the wet/dry mix between the original unprocessed vocal sound and the effects loop.

Power
Voco-Loco comes with an external 400mA 15VDC supply for powering. 

Line Output
Standard XLR male output, used to connect the Voco-Loco to the line input of a mixing console.

Lift
Used to help eliminate ground loops by lifting pin-1 on the XLR.

180° 
Used to reverse the polarity of the effects loop to ensure guitar pedals are in phase with the vocal mic.

Send / Receive
Unbalanced ¼” jacks used to send the mic signal to the guitar pedals and back into the Voco-Loco. 

48V
Recessed switch turns on the phantom power when using the Voco-Loco with a condenser microphone.

Mic Input
Standard XLR female input, used to connect your microphone to the Voco-Loco.

14-Gauge Steel
Heavy duty construction eliminates stress on the PCB and provides excellent shielding against magnetic fields and RF which otherwise could introduce noise.
