Introduction to the Benchmark DAC3 B

The Benchmark DAC3 B stands at the pinnacle of digital-to-analog conversion technology, representing the basic model in Benchmark’s acclaimed DAC3 series. Designed with uncompromising audio purity in mind, it delivers unmatched performance suitable for professional studio applications and audiophile environments alike.

Superior Audio Performance

Built upon the foundation of Benchmark’s renowned DAC2 series, the DAC3 B incorporates cutting-edge technology centered around the ESS Technologies ES9028PRO converter chip. This ensures exceptionally low Total Harmonic Distortion (THD) and THD+N noise, surpassing its predecessors and setting new standards in digital audio clarity.

Features and Specifications

  • ESS ES9028PRO Converter: Delivers pristine audio fidelity with lower THD and improved signal-to-noise ratio.
  • Advanced Digital Processing: Supports 32-bit internal processing with 3.5 dB of digital headroom, preventing DSP overloads and maintaining signal integrity.
  • UltraLock3™ Jitter Attenuation System: Ensures minimal jitter artifacts, achieving precise phase accuracy in just 6 milliseconds.
  • Quad 32-bit Balanced D/A Conversion: Summing four 32-bit D/A converters per channel reduces noise and distortion, offering unparalleled audio performance.
  • Asynchronous USB Audio: Supports high-resolution 192kHz playback and native DSD conversion, ensuring seamless integration with computer-based audio systems.

Studio-Grade Transparency

Benchmark DAC3 converters are celebrated for their transparency and neutrality, making them indispensable tools in professional studios worldwide. Unlike competitors that add coloration to audio, the DAC3 B faithfully reproduces recordings with unparalleled accuracy, preserving the artist’s intended sound.

Enhanced User Control and Integration

  • Remote Control: Includes IR remote compatibility and a control-lock feature for preventing unintended adjustments.
  • Integration Flexibility: Supports 12V trigger functionality and optional rack-mount installation, optimizing system integration in various setups.

Comparison with Previous Models

The DAC3 B builds upon the success of its predecessors by introducing active harmonic compensation, faster signal switching, and enhanced frequency response. It retains the familiar form factor and features of the DAC2 series while elevating performance to meet the demands of modern digital audio applications.

Ideal Applications

Ideal for critical listening environments and high-end home audio setups, the DAC3 B ensures that every nuance of the music is faithfully reproduced without distortion or alteration.

Conclusion

Embodying Benchmark’s commitment to excellence, the DAC3 B sets a new benchmark in digital-to-analog conversion. Whether in a professional studio or a discerning audiophile’s listening room, it provides a gateway to the purest form of audio reproduction available today.
