Radial Engineering EXTC-SA REAMP & Guitar Effects Interface. The Radial EXTC-SA is a stand-alone audio interface that lets you incorporate guitar effects into the realm of pro-audio recording. Just imagine add a touch of grit to a vocal track, some wah on a kick drum, maybe flange a violinThe EXTC is a creative tool made for your esoteric-inventive side, ready to unleash fresh new sounds that will make your recordings stand out from the crowd. And it’s super easy to use: connect a line level signal from the recording system. The EXTC-SA unbalances the signal and converts it to high impedance where guitar pedals can be inserted at will. Simply plug in, turn the track on, set your levels and adjust the blend for just the right amount of magic. Be prepared for instant amazement. Features include Radial’s award winning 100% discrete class-A guitar buffering for ultimate audio integrity, transformer isolation to eliminate buzz and hum caused by ground loops, 180º polarity reverse to keep effects and balanced signals in phase, and two loops that can let you compare signal paths or combine them to create your magical masterpiece. The Radial EXTC-SA is without a doubt one of the most innovative effect manipulating devices ever made. And it opens the door to new sounds by taking Reamping technology to an all new level. Be prepared for wild & wonderful! Balanced interface for guitar effects pedals. Separate send & receive controls optimize signal path. Transformer isolation helps eliminate ground loops. Creative tool helps your mix stand out from the rest. With more and more recordings being processed’in the box’ so many tracks are beginning to sound like they come from the same digital library. And for some, the’box set of plug-ins’ limits creative options. These innovators are constantly looking at the tools in their cupboards, thinking of ways to come up with new ideas or a new approach. They want their recordings to stand out from the crowd. This is what the EXTC-SA is all about. Creativity experimentation expanding boundaries. The EXTC-SA takes an old idea of incorporating guitar effects pedals into the recording world and makes it easy. It is basically an extension of a process called Reamping where you take a pre-recorded track, send it to a series of pedals, turn knobs, and send the processed sound back to the recorder. It is organic, analogue and most of all, fun. Laying Out the Design. The fundamental concept behind the EXTC-SA is fairly simple: take a professional +4dB balanced signal, unbalance it and then convert it to a guitar level output so that it will not overload the sensitive input circuit of a guitar pedal. After the guitar pedals process the signal, send the signal back into the EXTC-SA, amplify it to a professional +4dB signal and balance it to make it compatible with professional recording equipment. Because engineers are an unruly type, we figured that they will likely want to mess with signal levels to cause mayhem and destruction. To help make this easy, we introduced separate send and receive controls that could be adjusted as needed. To suit the record company executive, we then added a blend control that would enable the engineer to dial in as much of the mayhem as he can get away with. Think of it as balancing good and bad in the analogue world. Easier Said than Done. Anyone that has played with guitar pedals knows that these are generally band limited and noisy. And when you try to interface these high impedance devices to balanced line level signals, buzz and hum seem to find their way into everything. To minimize the problem, we equipped the EXTC-SA with transformer isolation to help eliminate troublesome ground loops. But ground loops are not the only concern. When you boost a low level guitar signal up to a balanced line level signal you are basically creating a preamplifier. And we know all too well how painfully fussy guitarists can be about buffers and their tone, so we made sure the EXTC-SA was made from 100% discrete, full size parts and employed class-A buffers and made it as quiet as possible. The next problem came when addressing wet and dry signals. In the world of professional audio, keeping everything in phase is normal. Not so with guitar pedals. Because the guitar signal is usually’mono’, the pedal designer does not have to concern himself with the signal polarity. But as soon as you mix wet with dry, you have to come to terms with the likelihood of phase cancellation. We added a 180º polarity reverse to solve the problem. With a push of a switch, you can compare. Bending down to adjust pedals in no fun. In the studio it is all about quick changes making decisions and dialing up spectacular to sublime. And today, we work using desktop computers, desktop mixers, connected to desktop monitors. This is why we put the ¼ send & receive jacks right on the front panel. You grab some cables, connect, adjust and create. No fussing around on the floor or reaching behind a rack. Your effects can be right on the desktop for easy adjustments. EXTC-SA Using & Applications. Overview The Radial EXTC-SA is a professional audio interface that takes a balanced line level signal and converts it to an unbalanced guitar-level effects loop and then re-converts it back to a balanced line level for processing. It is designed to be used with both traditional API style 500 series Lunchbox frames and the more advanced Radial Workhorse. This quick reference guide assumes you are familiar with 500 series modules and racks. Complete details on using the EXTC-SA and making connections to and from your 500 series rack can be found in the manual. Making Connections As with all audio equipment, always turn levels down and/or turn equipment off before making connections. This will help avoid turn-on transients that could damage speakers or more sensitive audio equipment. Plug the EXTC-SA into the Workhorse or 500 series rack. There is no power switch on the EXTC-SA. It will automatically turn on as soon as it is plugged in. 500 racks are usually equipped with a balanced XLR-female input to connect from your recorder and a balanced XLR-male output to send back to the recording system. If you have a Workhorse, the rear panel ¼ jacks can be used. To connect your pedals, simply plug the ¼ send to your pedal chain and the output of the pedal chain back to the EXTC-SA receive input using standard Hi-Z guitar cables. We suggest you start with one pedal first before using acomplete chain as this will make it easier to trouble shoot when first setting up the EXTC-SA in your system. Checking the Signal Path Begin by setting the send and receive controls to 12 o’clock and the blend control all the way clockwise to the 5 o’clock wet position. Turn on the effects and play the desired track. You should be able to monitor the return path in your recording system and hear the effect. Separate send & receive controls makes it easy to adjust the levels to suit. Now, try varying the blend control by rotating it counter-clockwise towards the dry setting to hear how the effect mixes in with the original track. If you notice that the signal is’thinning out’ when you are adjusting the mix, the wet and dry signals may be out of phase with each other, thus causing cancellation. Try depressing the 180º polarity reverse to fix the problem. Adding a Second Loop If you have a Workhorse, you can use the Omniport to add a second effects loop in series after the front panel pedal chain. This is ideally suited for studio effects or to wire to a studio patchbay. The Workhorse TRS jack is wired tip-send, ring-receive following convention. To turn on, depress the insert-on switch on the front panel. Listing and template services provided by inkFrog.
