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.
We would not recommend spending extra money to get the 192 kHz version if a 96 kHz version is available.
Our DAC2 D/A converter will provide exactly the same performance at either 96 kHz of 192 kHz. However, in most cases, many A/D converters (used to record the music in the studio) achieve better performance at 96 kHz than they do at 192 kHz. But, these differences will be very small.
