SMSL SU-2 Desktop DAC (Apos Certified)
type: Product
description: SMSL SU-2 ES9039Q2M DAC The SMSL SU-2 is a compact, fully-balanced digital-to-analog converter designed for monitoring, desktop audio, and active speaker systems. It offers clean signal delivery, stable connectivity, and measurable performance: AES/EBU input, balanced XLR output, and a low-noise analog stage built around four OPA1612A op-amps. Fully balanced signal path The SU-2 is designed around a fully-balanced architecture, from digital input through analog output. Balanced XLR outputs reduce noise over longer cable runs and help preserve signal integrity when feeding active monitors or balanced amplifiers. AES/EBU connectivity for stable digital input An AES/EBU input provides a professional-grade digital connection with strong noise rejection and clock stability. It's great for monitoring chains and desktop systems where reliability matters. Coaxial and optical inputs are also available for broader source compatibility. High-performance ES9039Q2M DAC architecture The SU-2 uses the ES9039Q2M DAC chip, chosen for its low distortion and high dynamic range. Measured THD+N reaches as low as 0.00006 percent, with SINAD up to 123.5 dB on balanced output. Four OPA1612A op-amps for low-noise amplification The analog stage uses four OPA1612A operational amplifiers arranged in a symmetrical layout. This design prioritizes channel matching and low crosstalk. The result is stable linear amplification across a wide bandwidth, with consistent left-right balance and controlled noise. Clear visual indicator system The front-panel indicator array shows input selection, signal lock status, channel activity, and sampling rate at a glance. Sampling rate changes are briefly indicated, while left and right channel indicators respond to incoming audio. It is functional feedback, not decoration. Compact, desktop-friendly design The SU-2 measures 5.9 inches wide, 1.7 inches tall, and 5.2 inches deep (150 × 42.5 × 133.1 mm). It fits easily on a desk or shelf without crowding other gear.…
