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 TX uses a discrete buffered circuit to drive your signals over long distances, while the SGI RX captures the signal and converts it to the appropriate impedance to feed your amplifier while retaining the original tone.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003cimg src=\"https:\/\/www.radialeng.com\/wp-content\/uploads\/2025\/01\/SGI-Graphic-768x480-1-768x480.jpg\" class=\"img-fluid product-shot photo-gallery-popup p-left\"\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-12 col-sm-6\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003csection\u003e\n\u003cdiv class=\"container\"\u003e\n\u003cdiv class=\"row content-block\"\u003e\n\u003cdiv class=\"col-12 col-sm-6 order-2 order-sm-1\"\u003e\n\u003ch2\u003eJensen transformer equipped\u003c\/h2\u003e\n\u003cp\u003eThe SGI system now proudly sports premium Jensen transformers inside: one in the SGI TX and one in the SGI RX. These transformers aren’t just there to help with isolation to prevent hum and buzz from ground loops – they are a key part of the circuit that converts the signal at each end of the system. Using industry-leading Jensen transformers in the SGI helps achieve a wider, flatter frequency response, lower noise and distortion, improved dynamic range and a greater signal to noise ratio. All of this helps deliver audio cleanly across long distances without any alteration to your original signal.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.radialeng.com\/wp-content\/uploads\/2025\/01\/SGI-768x480-09-768x480.jpg\" class=\"img-fluid product-shot photo-gallery-popup p-right\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-12 col-sm-6 order-1 order-sm-2\"\u003e\n\u003csection\u003e\n\u003cdiv class=\"container\"\u003e\n\u003cdiv class=\"row content-block\"\u003e\n\u003cdiv class=\"col-12 col-sm-6\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003csection\u003e\n\u003cdiv class=\"container\"\u003e\n\u003cdiv class=\"row content-block\"\u003e\n\u003cdiv class=\"col-12 col-sm-6\"\u003e\n\u003ch2\u003eNow pedalboard friendly\u003c\/h2\u003e\n\u003cp\u003eThe SGI ships with an included 15V power supply to power the TX transmit unit, but it can also be used with standard pedalboard power supplies, making it easier to integrate onto a pedalboard.
