NATIVE DSD CONVERSION


All digital inputs on the DAC3 support native PCM or DSD conversion. From any input, DSD is transported with bit accuracy over DoP 1.1. DSD and PCM are both natively converted to analog. There are no DSD to PCM or PCM to DSD conversions to compromise the quality of the music. The DAC3 conversion system seamlessly switches between native PCM and native DSD conversion. DSD over DoP 1.1 is supported by many media players, and DSD downloads are now available from several sources.

DIRECT CONNECTIVITY TO POWER AMPLIFIERS


Benchmark DAC1, DAC2, and DAC3 converters are designed to directly drive power amplifiers and speakers. Benchmark converters feature adjustable low-impedance passive attenuators at the XLR outputs that can be used to optimize the interface to the power amplifier (or powered monitor). This unique Benchmark feature optimizes the gain staging between the DAC and the power amplifier. Proper gain staging cannot be overemphasised. When audio stages are properly matched, each component in the audio chain is able to operate at its optimum signal level, and the system performance is significantly improved.

A NEW REFERENCE - GOING BEYOND THE LEGENDARY DAC1 AND DAC2


The DAC3 is Benchmark’s newest 2-channel D/A converter featuring the new ESS Technologies ES9028PRO converter chip. The DAC3 converter has lower THD and THD+N noise than Benchmark’s DAC2 converter.

Benchmark’s DAC1 and DAC2 D/A converter families have been the reference to which other converters have been compared. It is rare to find a converter review that does not draw comparisons to the DAC1 or the DAC2. Benchmark converters are in daily use at many of the world’s finest recording studios and mastering rooms. Benchmark converters are also enjoyed by thousands of audiophiles. Benchmark has raised the bar again … the DAC3 defines a new reference.
