Accuphase Laboratories, Inc. (originally known as Kensonic Laboratories, Inc.) is a Japanese manufacturer of high-end electronics. Accuphase Laboratories was founded in 1972 by disgraced Kenwood Corporation engineer Jiro Kasuga. Kasuga did not agree with Kenwood’s position in the approach to the development of equipment; many of its developments never reached mass production due to commercial unprofitability for the corporation. After a series of negotiations with Kenwood management, Kasuga creates the Kensonic brand, where it lures several leading engineers from Marantz and Luxman companies.

The name Accuphase was made up of the prefix “ACCU” – from the word accurate, “accurate”, and the word PHASE, “phase”, which is the most important characteristic in sound reproduction technology. This trademark is very suitable for the company’s products, since it reflects this and other important characteristics and penetrates the very depths of sound reproduction technology.

In the endless struggle for better quality, which requires a very high level of production organization, it was decided to abandon assembly line methods. In this regard, production volume is limited, and Accuphase brand products can only be purchased in some specialized stores. Accuphase equipment is not subject to the whims of fashion, since it is created, first of all, for the sake of truly high fidelity sound reproduction. This is the main reason why these products have not become the subject of mass production.

The Accuphase DG-58 digital equalizer now raises the bar again. This is a 4th generation product that reflects the state of the art in signal processing technology developed by Accuphase. The user experience has also been improved with two Simple Voicing courses for automatic metering and compensation, as well as a Custom Voicing course that gives users the ability to implement a specific acoustic concept with extensive control over all aspects.

Most operations are controlled via a widescreen HD color LCD panel. This makes using the included stylus a pure joy, allowing the user to create any response they want simply by drawing on the screen. Accuphase DG-58 takes the concept of intelligent leveling to the next level and at the same time remains simple and intuitive to operate thanks to its clean and uncluttered graphical interface.

Ease of operation has also been enhanced, with two courses of “Simple Voicing” for automatic measurement and compensation, as well as “Custom Voicing”, giving users the ability to implement a specific acoustic concept with extensive control over all aspects. Most operations are controlled via a large, high-resolution, widescreen LCD screen. Accuphase DG-58 takes the concept of smart equalizer to the next level, while remaining simple and easy to operate with a clean and uncluttered graphical interface.

Accuphase DG-58 – digital multi-band equalizer gives complete control over the sound. This equalizer allows for fully digital processing of signals from any sources, including SACD; it has functional modules for sound field correction (Voicing) and sound field creation (Equalizer). It can store 20 preset characteristics in its memory. In spectrum analyzer mode, the DG-58 displays the frequency components of a music signal in real time. The equalizer is equipped with high-speed 40-bit floating point signal processors that implement a sophisticated signal processing algorithm. Operating the device is intuitive and easy.
