DJM 2000 No USB Audio output at 48hz on Mac

Hi All,

Hope someone can help.

Currently using 3 different Macs, 2 with Mojave and 1 with Captain Op system. Just purchased a DJM 2000, downloaded the latest Drivers, But as soon as I select DJM 2000 Output as the Output Device, it Refuses to work in the Default 48hz mode and freezes up.

After a day of trial and error I discovered it will only work if i reselect 44hz. 

From Pioneer: ASIO: Sampling frequency - 44.1 k/48 kHz, bit depth - 16/24 bits. A maximum of 4 sets of audio signals can be input to the DJM-2000.

Does anyone know if this is a Fault or know of a Fix ?

Look forward to any of your Help or Advice
