Designed to solve many instrument recording and DI problems, the Smart Deluxe DI System is a unity gain toolbox allowing one-to-many distribution of instruments or timecode. It frees you from ground loops, sound degradation, and other problems inherent in driving long cables.

Conceived at Real World Studios to solve the problem of a guitarist wanting to play in the control room, and yet have amplifiers set up in a live room several hundred feet away. Prototypes were also used at Virgin/ EMI Townhouse and Manor studios. Since then producers and artists such as Tom Lord Alge, Peter Gabriel, Paul Weller, and Tears for Fears have bought systems.
 
Four systems were used to cure problems for Peter Gabriel's live show, where two stages had to be inter-connected with 300 feet of cable carrying guitar signals from radio packs to FX pedals, and then back to amps on the main stage without degradation (allowing each stage to be patched independently).
 
The system comprises a TRANSMIT box and RECEIVE box: the TRANSMIT box has a high impedance input and line driver, which will drive long cables to the RECEIVE box.This feeds the DI/splitter giving two isolated outputs. (In the Deluxe version, there are two DI/splitters in both the TRANSMIT and RECEIVE boxes, giving 8 isolated outputs)
 
In addition, the RECEIVE unit has a speaker simulator input so you can plug the speaker output of an amp in for 'dirty' DI sounds with or without a speaker connected. All the DI/splitters on both boxes have break jack inputs and can be used as separate DI's if desired, as well as earth lift switches to stop hum problems. This means there are a total of 8 outputs with the Deluxe version (2 on the normal system); a line driver and receiver; and a speaker simulator.
