Accuphase DG-78 Digital Voicing Equalizer at All Elite Audio
The Accuphase DG-78 represents a significant evolution in digital room correction and voicing technology. As the successor to the DG-68, it delivers refined tools for optimizing sound reproduction in real listening environments.
Core Capabilities
The DG-78 functions as a fully digital voicing equalizer with independent sound field compensation and equalizer sections. It analyzes room acoustics and applies precise corrections to achieve more accurate frequency response and imaging. A Smooth Voicing feature simplifies initial setup, while advanced manual controls allow detailed adjustments.
High-precision DSP processing handles input signals up to 384 kHz natively without downsampling. This preserves signal integrity across a wide range of digital sources.
Technical Upgrades
- A/D Conversion: Uses Asahi Kasei AK5578EN 32-bit converters in four-parallel configuration per channel, supporting high sampling rates for clean digitization.
- D/A Conversion: Employs ESS Technology ES9028PRO chips in eight-parallel operation with Accuphase's MDS++ architecture. This setup contributes to low distortion and high signal-to-noise performance.
- User Interface: Features a redesigned electrostatic touch panel with warm-toned displays for improved visibility and intuitive navigation compared to prior models.
Connectivity and Integration
The DG-78 offers comprehensive digital and analog inputs/outputs, including HS-Link, coaxial, and optical connections. It integrates seamlessly into high-end systems as a dedicated processor with its own A/D, D/A, and DSP stages.
Practical Benefits in a Listening Room
Room modes, reflections, and speaker placement often introduce uneven response. The DG-78 addresses these through targeted digital filtering, helping deliver tighter bass, clearer midrange, and more coherent soundstaging. It suits both stereo and multi-channel setups where accurate tonal balance matters most.
