Use the Benchmark's XLR outputs and leave the internal jumpers in the factory setting as shipped. We always suggest the use of balanced lines, when available, to avoid any interference. With the active speakers' gain control setting all the way down, set the DAC1's volume at about 3 o'clock. Bring up the speakers' gain to about the loudest volume level you would listen. Then bring the DAC1 volume down to a comfortable level. This gives you good use of the Benchmark's volume control range.What happens when 196/24 files are played via the DAC1 USB?
How can I use two Benchmark USB DAC units at once?
In some cases, upsampling will improve the output of your D/A converter. The low-pass filters incorporated into the upsampling process will essentially replace the filters in your D/A converter. If the upsampling software has better filters than those built into the D/A, then you may see an improvement.
Caution: Do not remove the internal safety cover that encloses the AC power entry.
Note: The cover is designed to fit tightly against the side of the unit.
The ADC1 converters have the ability to provide 16-bit outputs on the auxiliary output while providing high-resolution outputs on all other outputs. The 16-bit output mode is always TPDF dithered. The auxiliary output can be set for 16-bit operation or 24-bit operation. All other outputs are always 24-bit.
The ADC1 converters also have the ability to output up to 3 different sample rates simultaneously. The USB, Main, and Aux outputs are independent. The sample rate of the USB output is controlled by the computer.
