Accuphase, distributed by Advance Audio Australia, unveils the DC-500 digital processor and the DG-78 digital voicing equaliser, both aimed at bringing high-end performance and advanced system control to more accessible price points within the brand’s ecosystem.

The DC-500 digital processor functions as a high-performance DAC, featuring coaxial, TOSLINK and USB-B inputs alongside balanced and single-ended outputs. Positioned as a more accessible entry point into Accuphase digital conversion, it sits at roughly half the price of the DC-1000 while retaining core architectural principles used in the flagship model.

Internally, the DC-500 employs eight ESS Technology DAC chips operating in parallel for PCM and DSD processing, alongside an active noise-cancelling filter designed to reduce noise floor performance.

While it shares the same connectivity and processing philosophy as the DC-1000, the DC-500 differs in physical design and construction, including a reduced chassis footprint and the absence of the timber exterior finish found on higher-end models. The multi-chip parallel DAC approach remains consistent with its established design methodology used across its digital processors.

Alongside the DC-500, Accuphase has introduced the DG-78 digital voicing equaliser, a successor to the DG-68 designed for high-resolution room correction and system tuning. The unit provides both digital and analogue inputs and outputs, supporting integration across a wide range of hi-fi systems.

The DG-78 retains the three core operating modes found in its predecessor: ‘Voicing’, which uses DSP-based room correction derived from in-room measurements; ‘Equaliser’, which allows users to manually adjust and store multiple tuning profiles; and ‘Analyser’, which provides real-time frequency response visualisation during playback.

The updated model replaces the DG-68’s pressure-sensitive interface with an electrostatic touch panel that can also be operated via stylus, alongside a redesigned internal circuit layout aimed at improving overall performance.
