3:1 PARALLEL CONVERSION STRUCTURE
The conversion system in the DAC3 DX achieves a 4.77 dB signal to noise improvement through the use of 3:1 summing on the main output bus. The ES9028PRO D/A is an 8-channel 32-bit converter. In the DAC3 DX, three channels are summed in the analog domain to form each of the two output channels on the main bus. The remaining two channels provide the aux bus outputs
The 3:1 summing also improves the THD. The non-linearities in individual conversion channels are averaged across the four summed channels and incoherent non-linearities are attenuated by up to 4 dB.
The ES9028PRO has two distortion compensation systems that independently remove most of the 2nd and 3rd harmonic distortion in the D/A converter. Benchmark's ultra-clean analog output stages allow these systems to be fully leveraged in the DAC3 series. To the best of our knowledge, no other D/A converter has lower THD than the Benchmark DAC3 series.
The DAC3 DX is Benchmark's newest 2-channel D/A converter. When compared to the legendary DAC1, the DAC3 series has lower noise, lower distortion, and improved accuracy. The DAC1 and DAC2 series converters have become the reference standard in many of the finest recording studios and mastering rooms. The DAC3 defines a new reference.
DAC3 converters deliver outstanding musical detail and precise stereo imaging. They employ an advanced high-headroom digital filter design, and a high-sample-rate Asynchronous USB Audio interface. All inputs are fully isolated from interface jitter by Benchmark's new UltraLock3™ jitter attenuation system.
Internal digital processing and conversion is 32-bits, and includes 3.5 dB of headroom above 0 dBFS. Three balanced 32-bit D/A converters are summed together to form the main output bus. Two channels are reserved for the auxiliary RCA output bus.
he DAC2 DX uses digital connections (USB, Optical, Coaxial, or AES) to bypass the low-quality built-in converters that are included in many audio products.
