    1. When set to “Auto switch”, the sampling frequency is automatically selected according to the capabilities of the PC and USB-DAC connected externally based on the sampling frequency of the content.
    2. If you set "44100" etc., it will be played at the selected sampling frequency regardless of the sampling frequency of the content.

Even with a DAC that is not compatible with DSD 11.2 MHz, you can play sound by down-converting to DSD 5.6 MHz or less with a proper setting of PrimeSeat software. However, please note that it is out of our support for playing by down-conversion.

If you encounter problems like the sound being interrupted while playing by down-conversion, check the specification of the DAC you use and select a sound source with an adequate sampling rate and listen to it.

If you play sound by down-conversion, it is recommended that you open the “Audio setting” screen of PrimeSeat and set the “Buffer size” to its maximum value.
