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.
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.
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.
