EXTC™-500 GUITAR EFFECTS STUDIO INTERFACE

The EXTC is a 500 series interface that enables more creatively inclined engineers to introduce
guitar pedals into the signal chain. The EXTC takes a balanced signal, unbalances it and reduces the
level so that it can properly interface with hi-Z guitar pedals. Once the signal is processed, the EXTC
reverses the process by taking the unbalanced signal and reconverts it back to a +4dB balanced line
level signal for easy manipulation in the professional recording environment. This, for instance, lets
you add wah to a kick drum, tube distortion to a vocal track or maybe an old-school tape echo to an
acoustic guitar. As pedals can be noisy, the EXTC is transformer isolated to eliminate hum and buzz
caused by ground loops. A 180° polarity reverse ensures the wet-dry mix is in phase.

FULL ENCLOSURE - 100% steel casing reduces magnetic interference
from other nearby modules that may cause pollution.

BLEND CONTROL - Adjusts the wet-dry mix between the
original unprocessed signal and the EXTC’s effects loop.

180º POLARITY - Lets you reverse the polarity of the wet signal path
and bring it into phase with the dry signal when they are being
mixed together.

Applications

• Lets you fatten up a track using pedals

• Add guitar effects like overdrive to voice

• Lets you use effects pedals in new ways

• Creative tool to make your tracks stand out

Cool factors

• Super easy to use – The EXTC does it all!

• Isolated output to eliminate ground loops

• Wet-dry mix to adjust the balance

• Can also be used for Reamping!

OMNI INSERT - Turns the Omniport insert jack into a second send
& receive path for additional processing.

SEND & RECEIVE - Use to adjust the send level to the pedals and
return path level back into the EXTC to optimize the signal-to-noise ratio.

¼” SEND & RECV - Separate send and receive ¼ jacks used to connect
guitar pedals to the EXTC. Front panel mounted to make connections
easy for use on the desktop.

OMNIPORT™ - TRS jack is set up as an insert to connect to a remote
patch bay or effect device. This follows the tip-send, ring-receive
convention. Available when used with Radial Workhorse racks.

GOLD 15-PIN CARD EDGE - Double sided and gold plated edge
connector ensures good conductivity and signal transfer.

TRANSFORMER ISOLATION - Helps eliminate hum and buzz caused
by ground loops.

CLASS-A EFX LOOP - Radial’s legendary FET amplifier delivers natural
tone and optimal signal transfer for hi-impedance instruments and effects.

Reamping™ through Pedals

Take a dry track, send it to the EXTC which in
turn feeds your pedals. This is the perfect way to
add some extra zest to a vocal track; an envelope
follower to a kick; or some wah to that Hammond
track.

Adding Growl to a Vocal

Plug your mic into the PowerPre and send the
signal into the EXTC. From there, add an effect
like a Tonebone Classic Tube Distortion and use
the blend control to mix in just the right amount
of growl.

Recording Direct

Plug your guitar or bass into the JDVPre and
have it feed the EXTC where you can send the
signal through your pedals. Then bring the signal
back through the JDX to emulate a speaker
cabinet.
