Isolated guitar splitter / Di box

    Are you looking for a compact guitar splitter box with a high impedance input and two independent transformer galvanically isolated outputs? A combination of a splitter y-box which distributes guitar signal to two amplifiers and a powerful DI box for recording with your PC or in a studio? This is your best choice! N-audio Isolated guitar splitter / DI box is a great unit which combines both features and gives you the flexibility to use in different combinations.


    The N-audio Isolated guitar splitter / DI box has a high impedance input which is designed to connect your guitar, bass guitar, synth or any line level signal sources like the output of a guitar effect, a preamp, line level output from your PC audio interface or line level output from your mixing desk. There is also an extra output indicated as Link which is useful to connect another Isolated guitar splitter / Di box or for use as a direct output. Unlike typical transformer isolated guitar splitter this unit has two independent galvanically isolated outputs: Output A and Output B placed at the bottom of the guitar splitter. The heart of this guitar splitter is a high-quality audio transformer, which electrically isolates the two outputs, eliminating the possibility of ground loops and gives you an excellent common mode rejection ratio (CMRR). Each output has independent On-Off switch which turns on and off the output and ground lift switch with 2 positions: Lift and ground. Output B also has a phase reverse switch to prevent out of phase signal when two guitar amplifiers are used.

As a guitar splitter for two (or more) amps or combos
