Stereo Instrument Line Driver
The SGI Stereo is a line extension of our high-performance stereo line driver system for guitars. It takes a pair of unbalanced instrument signals and allows you to drive them up to 100 metres (300ft) over a single standard Cat5 Ethernet cable without noise or signal loss.
- Balanced stereo line driver for guitar pedals, pedalboards, or amp modellers
- Send signals up to 100 metres (300ft) without loss or noise
- Premium Jensen transformers for optimal sound quality
- Delivers natural tone to off-stage amplifiers
- Transmits analog audio over a single, economical Cat5 Ethernet cable
Take your tone further in stereo
The SGI Stereo is an updated two-channel version of our innovative SGI system. Featuring locking RJ45 Ethernet connectors (compatible with Neutrik etherCON locking connectors), the SGI Stereo allows a single Cat5 Ethernet cable to be used to connect the TX to the RX. This allows guitar players with stereo rigs to connect to dual amplifiers in a remote location, such as an amp room in a studio or when amplifiers are placed remotely on large stages. The system can also be used with a facility’s existing Ethernet infrastructure, which is beneficial for home studios and any applications where rooms are wired with Ethernet cables but no analogue studio tie lines.
How it works
The SGI Stereo consists of two boxes: the SGI Stereo TX transmitter and the SGI Stereo RX receiver. To use, simply plug your pedalboard output’s ¼“ cables into the TX Left/Right inputs, the TX to the RX via a single standard Cat5 Ethernet cable, and the Left/Right ¼” outputs of the RX to your amplifiers. The SGI Stereo TX uses a discrete buffered circuit to drive your signals over long distances, while the SGI Stereo RX captures the stereo signal and converts it to the appropriate impedance to feed your amplifier(s), while retaining the original tone.
SGI Stereo TX Additional features
The TX unit is now equipped with Left/Right ¼” Thru output jacks for sending unbalanced signals to local amplifiers or a direct box, eliminating the need to unplug from the SGI TX when connecting to nearby amps. If a connection is made to the Left Thru jack but not the Right Thru, both the left and right channels will be summed together on the Left Thru output.
SGI Stereo RX Additional features
The SGI Stereo RX unit is equipped with a 180° Polarity reverse switch for the Left Output, which can be used to correct signal cancellation for amplifiers wired out of phase, as well as independent Ground Lift switches for each channel.
Jensen transformer equipped
The SGI Stereo Line Driver system features premium Jensen transformers: two in the SGI Stereo TX and two in the RX. In addition to helping with isolation to prevent hum and buzz from ground loops, Jensen transformers 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 Stereo system helps achieve a wider, flatter frequency response, lower noise and distortion, improved dynamic range, and a greater signal-to-noise ratio, allowing you to deliver audio cleanly across long distances without altering your original signal and tone.
Economic cabling & Pedalboard friendly
The SGI Stereo 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 on a pedalboard. You can use any power supply from 9V to 18V, and both centre-pin positive and centre-pin negative polarities are accepted. The SGI Stereo also employs analogue audio over Ethernet, which requires no digital conversion and allows you to use a lightweight, economical standard Cat5 Ethernet cable to run long distances between the transmit (TX) and receive (RX) units easily, eliminating the need for XLR cables. It also allows you to connect using existing building Ethernet infrastructure to send signals between rooms without long cable runs.
SGI Stereo Applications
Using the SGI Stereo in the studio
The SGI Stereo 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 your guitar or pedalboard via two ¼” instrument cables to the TX, run a single standard Cat5 Ethernet cable to the RX, and crank to your heart’s content!
Using the SGI Stereo on stage
The SGI Stereo is a ready-made solution for large stages where high-impedance guitar signals are often affected by the capacitance of long cables or noise due to lighting systems. The SGI Stereo balances the signal from your pedalboard and delivers it without noise. Perfect for isolation cabinets, under stage amps, or remote 'quiet' rooms.
A solution to complex routing systems
The SGI Stereo system is a wonderful tool for managing complex setups on stage. You can also use an original SGI to route the signal from a wireless receiver to your pedalboard, then use a pair of SGI Stereo units to drive your stereo pedalboard output to remote guitar amplifiers and drive signals up to 100 metres (300 ft) without noise.
