RADIAL SGI STUDIO GUITAR INTERFACE S - Part Number 000239
SGI Studio Guitar Interface system Drive a guitar signal 300 feet without loss 100% discreet class-A electronics Drag Control pickup load correction Transformer isolated to eliminate noise Routes using standard balanced XLR cable The Radial SGI studio guitar interface allows a guitar signal to travel 100 meters (328 feet) over a standard balanced XLR mic cable. This enables the guitarist to play through a distant amplifier while listening to the performance in the control room. On large stages, the SGI allows a guitar signal to travel from the wireless system to a pedal board and amplifier. The SGI employs a proprietary drive and balancing circuit that is made up of two modules: the SGI-TX transmit module and SGI-RX receive module. The SGI-TX is active with 100% discreet class-A circuitry and Drag� control load correction to ensure the most natural sound. The SGI-RX is completely passive. To eliminate hum and buzz caused by ground loops, each module is equipped with isolation transformers that are wired in opposing directions to counteract any artifact. Best of all, the SGI is plug & play easy to use and comes equipped with power supply. SGI Setup: Plug a standard 1/4" guitar cord into the SGI-TX input. Plug the TX 's low-Z XLR output into one end of a standard balanced mic cable up to 300 feet long and the other end into the SGI-RX receiver module's XLR input. The standard 1/4" output of the RX connects to your amp, mixer or effects. Dial up the perfect pickup loading for your guitar with the TX's Drag� control and use the RX's ground lift switch if you need to eliminate any hum or buzz. ... Now you are all set to enjoy playing guitar in the control room while your amp setup remains on the sound stage, hundreds of feet away, with perfect guitar sound and zero signal loss or degradation. Radial SGI� In Detail SGI Development With the advent of affordable digital recording, musicians at all levels are gaining technical competence and adopting a more active role throughout the recording process. Add to this the comfort of having everything at arms length in a single room studio and the natural evolution to the project studio and then to multi-room facility, it is easy to see how a new breed of musicians is now emerging: These artists have learned to work �behind the glass� and make spontaneous decisions by reaching for a guitar, bass or a keyboard, all the while monitoring the performance in the control room through the reference monitors. This is driving a new creative relationship whereby the artist is making engineering and production decisions along side the studio technocrats. The only time they exit the control room or play with headphones is when they are playing instruments that are acoustic and recording with open mics or when playing instruments that are simply too loud to be in the same room such as electric guitars. The Radial SGI Studio Guitar Interface provides a simple and affordable solution that lets the guitarist plug into the SGI and drive the guitar signal over standard XLR mic cables to a far-away isolated room and listen to the sound over the studio reference monitors. Being able to monitor the performance �live� makes it easier to dial-in the perfect sound for a given track, thus saving valuable studio time. Dub-ins are now easier to re-record as the guitarist can now control the recorder and assign new tracks without having to relay information over an intercom. With the Radial SGI in your system, recording just got a whole lot easier! But this is just the beginning� On live stages, noise typically encountered when using long, high-impedance cables is now eliminated. Add the Radial JD7 Injector to your system and you can now run multiple amps and effects at the same time. Combine the SGI with a Radial J48 direct box on bass guitar and now you can mix the sound of the bass amp and the direct feed to create thicker, fatter tones. Because you are no longer limited to being in the same room as the amplifier, all kinds of new possibilities open up� and just maybe, this will add a little creative spark to the performance. Now isn�t that what music is all about? SGI Features The Radial SGI is made up of two modules: The SGI TX transmitter and the SGI RX receiver. These are connected using standard balanced twisted pair cable, thus enabling the SGI to be used in any studio or stage environment. Both are made from 14 gauge steel using Radial�s unique I-Beam construction and protective book-end design. This ensures the Radial SGI will continue working for years even when tossed around in adverse conditions. A full-bottom rubberized pad has plenty of �stay� while providing both mechanical and electrical isolation while providing a protective barrier that will not scratch your Pro-Control. The SGI-TX Transmitter Module: When using the SGI, the guitar connects to the SGI TX transmitter. This is a 100% discreet class-A active driver that employs the same front end and circuit topology found inside the popular Radial JD7 Injector. Class-A circuits are the preferred choice o audiophiles as they retain the natural characteristics of the instrument by eliminating zero-cross distortion which in turn reduces harmonic distortion, inter-modulation distortion and phase shift. To counter any effect of the circuitry, the SGI is equipped with Drag Control, our innovative load correction circuit that reintroduces the natural relationship between the guitar and amplifier that would otherwise be lost. Power is supplied by a 15VDC external supply for added headroom over 9V systems. Both transmit and receive modules are equipped with isolation transformers to eliminate buzz and hum caused by ground loops. The Radial SGI-RX Receiver Module: When in use, the amplifier is connected at the receive end using the SGI RX. This module is completely passive thereby not requiring local power. The transformer receives the signal and is wired �in reverse� to counteract any ringing that may be induced at the input side. Smart. This also eliminates ground loops, a common problem when connecting equipment using different electrical circuits. Using the SGI The SGI is truly plug & play easy to use. The unity gain circuit simply relays the input level to the output for a natural tone. To use the SGI, start by making sure the guitar amplifier is off. Connect the SGI TX and RX modules together using a standard XLR cable. Connect the DC supply to the SGI and the LED on the front panel will illuminate to show power is present. Connect the guitar and amplifier, turn the amp on and play. For best results, we suggest that you start with a clean tone and set the Drag Control to 50% or 12 o�clock and then adjust to suit. More drag will result in a darker tone, while less drag will reduce the load on the pick-up and add sparkle.
