This Fidelity D.I. is a direct injection box

of studio quality to be converted to the

original sound balance signal faithfully

without impairing its signal. You can

express the faithful original sound

directly of individual instruments on low

noise and highquality at any situations of

the live-shows or the studio recordings.

Not Change the Gain of Original Sound
Not Distort the Sound Signal
Wide Response of the Input Impedance
Send the Pure and Natural Sound
Without Deterioration of Signal

I produced this Fidelity D.I.

based on these concepts.

Also you can use this Fidelity D.I. on

various musical instruments from

passive pickup of electric bass guitars

and electric guitars until a keyboard of

the line output by using the -20dB pad.
