The new and improved Radial SGI features Jensen transformers for unmatched clarity and now works with a standard 9V power supply. Send your guitar signal over long distances with zero noise or tone loss. Perfect for studio or stage, the SGI handles control room-to-amp connections, off-stage isolation setups, or signals through wireless systems, pedalboards, and amps. With the SGI-TX transmitter and SGI-RX receiver connected via a standard XLR cable, balancing and buffering has never been easier.
