SGI™ Using & Applications

The following is a short form guide on how to use the SGI. For full details, please download the SGI User Guide by clicking here or on the icon at the right.

Over View

The SGI is basically a guitar cable extender that can be used with electric guitar, acoustic, bass and just about any instrument. It is designed for unbalanced instrument level use. The setup consists of two parts: a transmitter (SGI-TX) and the receiver (SGI-RX). The SGI-TX transmitter is active which means it requires a power supply while the SGI-RX receiver is passive, meaning that it does not require any powering. This allows it to be easily moved around the studio or stage without having to find an AC outlet. Simply power up the SGI-TX using the supplied 15VDC power supply and the SGI system will manage the rest for you.

Connections

The connection between the two modules is made using a standard XLR cable. This can easily drive runs as far as 100 meters (300 feet) or more. Simply connect the guitar or bass to the SGI-TX ¼" input and a guitar cable from the SGI-RX output to the amplifier and you will hear it come out of the other end. If you hear any noise, try lifting the ground by depressing the switch on the SGI-RX. Nothing can be easier!

Using the Drag Control™

In order to ensure the sound going to the amp via the SGI equals the tone when connecting your guitar 'direct', a special function called Drag Control lets you adjust the load on the pickup to simulate the feel and tone as if connected directly. Begin by setting the Drag Control to 12 o'clock. Turning the control clockwise will brighten the tone while turning it counter-clockwise will warm it up. The control is recessed so that it can be set and forgotten. Use a guitar pick or screwdriver to adjust. Once the tone sounds the way you want, you are set to go. It's that easy.

Using higher output instruments

Devices like active bases, keyboards and acoustic guitars with built-in electronics may also be used with the SGI. Because these are already buffered with their internal active circuitry, the Drag Control will have little or no effect. Be careful not to overload the SGI input. Simply listen. If you hear distortion, turn down the source and the sound will clean up nicely.

Using the SGI on a stage with wireless system

One of the common uses for the SGI is to connect it from a wireless receiver to the pedalboard. The reason for this is that on big stages, the distances can be quite far which can cause a lot of noise to be introduced from lighting systems and electro-magnetic fields when running high-impedance cables. Guitar techs will often connect the output from the wireless into the SGI which in turn will feed a distant pedalboard. A second SGI will sometimes be used from the pedalboard to feed the guitar amp.

Although the SGI was originally intended for use in the recording studio, today artists around the globe are using it on concert stages, in houses of worship and on Broadway theatre productions. It is easy to use and sounds great!
