Fidelity D.I.
High Quality Real Sound Direct Injection Box

Unit in order to convert the signal

sent from instruments to the proper signal format

without changing the original gain,
also without distorting.

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 high quality 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.

Features

  • 2-channel Full-Active Circuit without deterioration of the sound quality.

  • Musically Sound Changing Filter using the high-quality film condenser.

  • Soft Edge Sound like a Tube

  • Compact size and Lightweight by aluminium case

  • Full Covered Functions of as the D.I.
