DAC3 DX keitiklis (DAC)
3:1 PARALLEL CONVERSION STRUCT
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.
SONICALLY NEUTRAL
All Benchmark converters are designed for maximum transparency. This transparency is absolutely essential in the studio monitoring chain. DAC3 converters are ideal for critical reference-quality professional systems. In home applications, the DAC2 delivers the sonic signature that was created in the recording studio.

A NEW REFERENCE - GOING BEYOND THE LEGENDARY DAC1 AND DAC2
Benchmark’s DAC1 and DAC2 series converters 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 DAC2. The DAC1 and DAC2 have been some of the best-selling 2-channel reference-quality converters and are in daily use at many of the finest recording studios and mastering rooms. Benchmark converters are also enjoyed by thousands of audiophiles. Benchmark has raised the bar … the DAC3 defines a new reference.
