Accuphase DG-58 Digital Voicing Equalizer

The DG-58 is the fourth generation digital voicing equalizer, developed using Accuphase's unique advanced digital signal processing technology.

It has two new simple voicing courses that allow automatic measurement and correction with simple operation, and a custom voicing course that allows thorough sound field correction to achieve your favorite sound.

The basic operation screen uses a large, high-definition wide color LCD display, and the functions can be operated with a stylus pen. The function of inputting the desired frequency curve by drawing it directly on the screen has been greatly improved, allowing for easier and faster operation.

This product revolutionizes the concept of sound field correction, and although it is a large-scale equalizer, it allows easy and graphical adjustment with a very simple operation system.
