Accuphase

Digital Voicing Equalizer

Since Accuphase's groundbreaking DG-28 redefined the graphic equalizer in 1997, the DG series has become an indispensable component for serious audio systems. The DG-78, the sixth generation in this lineage, pairs a 40-bit floating-point DSP with the latest A/D and D/A converter circuits to deliver advanced, high-precision signal processing for both analogue and high-resolution digital sources.

Key Features:

  • 40-bit floating-point DSP (Analogue Devices ADSP-21565) for high-precision full-digital signal processing
  • 4 parallel Asahi Kasei Electronics 32-bit A/D converters (AK5578EN) per channel
  • 8 parallel ESS Technology 32-bit D/A converters (ES9028PRO) per channel
  • ANCC circuitry in both A/D and D/A stages for reduced noise and distortion
  • Intuitive sound field correction via stylus pen on a high-resolution IPS LCD
  • Separate voicing and equalizer functions, each independently switchable
  • Wide connectivity: balanced/line analogue I/O plus HS-LINK Ver.2, coaxial, and optical digital I/O

With precise control over sound field and timbre, the DG-78 brings your system's true musical potential into focus.

Redesigned User Interface

The DG-78 features a revamped interface with warm-toned displays for better visibility and more intuitive operation. The display now uses an electrostatic touch panel, replacing the previous pressure-sensitive type, for smoother, more responsive control. Use the dedicated stylus pen or your finger for precise input — ideal for fine-tuning EQ curve settings.

Next-Generation Components

An ultra-high-speed DSP pushes filter precision to its absolute limit, while the DAC section incorporates ANCC circuitry to cancel distortion and noise. Every circuit section has been reviewed and optimized for peak performance.
