Introduction to Benchmark DAC3 HGC

Discover the Benchmark DAC3 HGC, the pinnacle of Benchmark’s DAC line, setting new standards in digital-to-analog conversion technology. Built upon the legacy of the acclaimed DAC1 and DAC2, the DAC3 incorporates state-of-the-art features and innovations to deliver unparalleled audio performance for both professionals and audiophiles alike.

Reference Performance and Advanced Technologies

Superior Conversion Quality The DAC3 employs the latest ESS Technologies ES9028PRO converter chip, offering significantly lower Total Harmonic Distortion (THD) and THD+N noise compared to its predecessors. This ensures exceptional musical detail and precise stereo imaging, making it a preferred choice in top recording studios and mastering rooms worldwide.

UltraLock3™ Jitter Attenuation Benchmark’s proprietary UltraLock3™ system ensures all inputs are isolated from interface jitter, providing precise clock synchronization and eliminating artifacts that can degrade audio quality. This advanced jitter attenuation system locks with unprecedented speed and accuracy, enhancing clarity and fidelity.

Quad 32-bit Balanced D/A Conversion Featuring a unique 4:1 summation of four balanced 32-bit D/A converters per channel, the DAC3 achieves industry-leading performance with reduced noise and distortion levels. This innovative design elevates signal-to-noise ratios and preserves audio integrity, setting new benchmarks in audio fidelity.

Enhanced Features and Functionality

Advanced Digital Processing The DAC3 boasts a 32-bit digital processing system with 3.5 dB of headroom above 0 dBFS, preventing DSP overloads common in other converters. It supports native PCM up to 192 kHz and native DSD64 conversion, ensuring uncompromised playback quality.

Hybrid Gain Control (HGC) Benchmark’s proprietary HGC system combines active analog gain control, passive low-impedance attenuators, and digital gain control for precise volume management without introducing noise or distortion. This ensures optimal signal purity and dynamic range, enhancing overall listening experience.

Integrated Headphone Power Amplifier (HPA2™) The DAC3 includes Benchmark’s renowned HPA2™ headphone amplifier, delivering high-current, 0-Ohm drive to ensure maximum performance with any headphones. Dual 1/4″ headphone jacks provide versatility without compromising audio quality, making it ideal for critical listening sessions.

Versatile Connectivity and User-Friendly Design

Multi-Mode Asynchronous USB Audio System Supporting USB Audio 2.0 and DSD playback, the DAC3’s USB subsystem features asynchronous communication to minimize jitter and support high-resolution audio formats up to 192 kHz. It offers plug-and-play convenience with MAC systems and includes a driver for seamless integration with Windows.

Comprehensive Connectivity Options The DAC3 includes a range of inputs including coaxial, optical, and AES/EBU, along with digital pass-through capabilities for integration with home theater systems. It features bi-directional 12V trigger functionality for automated control and a home theater bypass mode for seamless integration into multi-channel setups.
