SGI 15v Applications

Using the Radial SGI in the studio

The SGI is the perfect interface for studio recording. Now, you can sit in the control room and play guitar and actually hear what is coming through the monitors while you play. Simply connect the guitar into the SGI-TX, run a balanced cable to the SGI-RX and crank to your hearts content!

Using the Radial SGI on stage

The SGI delivers a ready solution for large stages where high impedance guitar signals are often affected by the capacitance long cables or noise due to lighting systems. The SGI balances the signal and delivers it without noise or artefact. Perfect for isolation cabinets, under stage amps or remote 'quiet' rooms.

A solution to complex routing systems

The SGI is a wonderful tool that can be used to help manage complex setups on stage. You can route the signal from the wireless receiver to the pedalboard, then use a second unit to drive the signal back to guitar amp and drive signals as far as you need to go without noise.
