The [Weiss Engineering DAC205-MK2] is a compact digital-to-analog converter designed for both professional recording studios and high-end hi-fi systems, focusing strictly on pure conversion accuracy.
The key technical specifications and updates introduced with the MK2 version include:
Core Hardware & Audio Architecture
- DAC Chip: The updated MK2 version utilizes the ESS ES9028PRO chip.
- Parallel Conversion: It features 4 parallel D/A converters per audio channel (Quad-Parallel) to significantly lower the noise floor and enhance sonic clarity.
- Jitter Suppression: Equipped with an advanced internal jitter elimination circuit to eliminate signal timing errors.
- Output Impedance: The MK2 brings an optimized output stage down to a near-zero-ohm impedance. This allows it to drive demanding amplifier loads or long cable runs without signal degradation.
Connectivity & Formats
- Digital Inputs:
- 1 x RCA (Coaxial)
- 1 x TOSLINK (Optical)
- Supports S/PDIF or AES/EBU digital formats. Two digital sources can be connected simultaneously and toggled via the front panel.
- Supported Sampling Rates: Processes PCM formats natively from 44.1 kHz up to 192 kHz with up to 24-bit resolution. (Note: The optical input typically maxes out at 96 kHz).
- Analog Outputs:
- 1 x XLR Stereo (Balanced)
- 1 x RCA Stereo (Unbalanced)
- Gain Attenuation: Features two toggle switches on the back panel allowing a 4-stage output level adjustment (in 10 dB steps) in the analog domain to perfectly match the input stage of your amplifier.
Power & Physical Build
- Chassis Material: Silver anodized aluminum housing.
- Power Requirement: Powered via an external DC 6V to 9V power supply, with a power consumption of 5.4W. It can be optionally upgraded with Weiss’s PSU102 ultra-low-noise linear power supply.
- Dimensions: 10.5 cm (Width) x 16.5 cm (Depth) x 6 cm (Height).
