Transmit over long distances without worry. The Radial SGI Studio Guitar Interface System is a premium line driver and features both a transmitter and receiver for transmitting an unbalanced guitar signal over 100 metres without noise. Ideal for both studio and stage use guitarists can connect to distant guitar amps or off-stage systems. Operating as a unity gain device the SGI includes discrete Class-A circuitry for excellent sound free from ground loop noise. The SGI transmitter provides level and impedance conversion automatically with a balanced signal for user-friendly operation. The receiver then converts the signal back into a hi-Z instrument level for pedalboards and amplifiers. With Drag Control the system allows guitarists to replicate the tone of their instrument as if through a tube amplifier.
