SGI Guitar Interface System

Studio Guitar Interface System

The SGI is a high performance line driver system for guitars that takes an unbalanced instrument signal and allows you to drive it as far as 100 meters (300ft) without noise.

Balanced line driver for guitar and bass

Send signal over 100 meters (300ft) without loss

100% discrete class-A circuit with Drag control

Delivers natural tone to off-stage amplifiers

Take your tone further

The SGI sends guitar signals across long distances without signal loss or noise, while retaining the original tone of the instrument. In the studio, it allows the guitarist to sit in the control room and connect to a distant guitar amp. On stage, the SGI can be used to play the guitar amp using off-stage isolation cabinets or it can be used to manage guitar signals to and from wireless systems, pedalboards and amplifiers. The SGI consists of two boxes: the SGI-TX transmitter and the SGI-RX receiver. The connection between the TX and RX is made using a standard balanced XLR microphone cable. To use, you simply plug your guitar into the SGI-TX input and connect your amp from the SGI-RX output and you are set to go. The SGI does all of the balancing, buffering and impedance matching for you.

SGI Specifications

Looking at the SGI specifications is both worthwhile yet deceiving. On one hand, looking at specs such as noise or signal handling will determine the quality of the interface. On the other hand, evaluating application specific devices like the SGI needs to be done by considering the source. A guitar for example tends to be a mid range device with a relatively low output. Ultimately… it comes down to how it actually sounds. And the SGI sounds great!
