Accuphase DG-68

Accuphase

Accuphase luo jännittäviä, maailman ehdotonta kärkeä olevia ja huipputeknologialla varustettuja laitteita mutta ei ehdolla millä hyvänsä. Siksi, vaikka Accuphase mielletään vahvasti teknologiasuuntautuneeksi yhtiöksi, erityisen siitä tekee sen uniikki yritysfilosofia ja ihanteet.

Accupase ei tähtää, eikä ole koskaan tähdännyt, yrityksen nopeaan laajentumiseen (oma pääoma ja yrityksen vakavaraisuus ovat tärkeämpiä), ei alennu kilpailemaan pelkällä hinnalla (pienet malli- ja valmistusmäärät mutta huippulaatua), ei tee äkkikäännöksiä laitesuunnittelussa (jokainen malli on tuotannossa vähintään neljä vuotta ja keskimäärin huomattavasti pitempään), valmistaa vain luotettavia kestäviä, korjattavissa olevia ja turvallisia laitteita, sellaisia jotka tuottavat silmälle iloa myös laitteiden sisälle katsottaessa! Se on myös sitoutunut eettisesti kestäviin markkinointikäytäntöihin.

Accuphase DG-68 -taajuuskorjain

In 1997, Accuphase introduced a product which revolutionized the concept of the graphic equalizer and made headlines in the audio world: the Digital Voicing Equalizer DG-28. Follow-up models in the DG series brought further improvements which garnered more praise and led to the recognition of the Voicing Equalizer as an indispensible component of the ultimate audio system

The Voicing Equalizer from Accuphase brings together two
major functions, namely sound field compensation for optimizing the acoustic properties of the listening room, and a graphic equalizer for adjusting individual frequency bands and thereby controlling the tonal quality of the music being played. A supplied precision microphone is used to measure the acoustics of the listening room and enable the automatic
creation of the sound field as desired by the user. The graphic equalizer function then enables further fine tuning and flexible tonal adjustments. As the word ”Voicing” also has the meaning of ”tuning”, the product was named with the idea of tuning the listening room

The fifth generation DG-68 is the result of a major redesign of the operational aspects of the Voicing Equalizer, making it even easier to explore its highly sophisticated capabilities. The dedicated DSP chip employs latest signal processing technology to effortlessly handle the input from both analog and high-resolution digital sources. A wide complement of digital and analog input and output connectors provides unprecedented versatility for various connection types, and the highly advanced A / D and D / A converters ensure dramatically improved sound quality and performance both on the analog input and output side.

The DG-68 incorporates three complementary functions.
The desired function can be selected easily with one of
the four large buttons on the HOME screen (there are
two choices for Voicing). The various buttons and graph displays that are shown for each function can be directly manipulated with the supplied stylus pen. For fine-tuning adjustments, the up / down / left / right cursor buttons at the right side of the front panel will also come in handy during input.

The Voicing function involves measuring the acoustic
characteristics of the room using a microphone and then
providing compensation to achieve ideal music reproduction
conditions. The user can choose between two adjustment methods for Voicing. With AUTO VOICING, the entire process is performed automatically for superior operation convenience. MANUAL VOICING gives the user full control over each item, enabling manual adjustment while checking the results.

The Equalizer allows adjusting the tonal result by selectively boosting or attenuating the level of the music signal in specific frequency bands. The DG-68 offers an amazing 80 bands covering the frequency range up to 100 kHz. By controlling the level in these bands, any desired frequency response can be created. While listening to actual music, use the stylus pen to draw a response curve. Being able to make adjustments visually while checking the audible result makes all the difference.

A spectrum analyzer makes it possible to display the actual frequency components of the music being played. The DG-68 divides the frequency spectrum into 35 bands, reaching up to 50 kHz. The level of each band is analyzed and shown on screen. When using the Equalizer, the Analyzer lets the user first check the spectral frequency distribution of the music, to determine where adjustments will be most effective.
