Hello, speaking of VirtualDJ, have you experienced any issues with the sound level when using Prime 4? I have tested the demo versions of VDJ on both OSX and Windows, and the sound is very low. Even when I turn up the sound settings on the Prime 4, there seems to be an issue somewhere. I have looked at the sensitivity settings in VDJ, but the sound level remains significantly lower than with Serato, which has a normal sound level. I was considering switching to VDJ to use the phases and the 1210mk2 occasionally with the Prime 4, but currently, it’s impossible due to the significant loss in sound level and dynamics. I think that what we gain in screen improvement compared to Serato, we lose in sound quality. I looked at the VDJ forum on this issue, and I wasn’t the only one. Other users have also complained about the low sound level. Perhaps there is a difference between older and more recent versions of Prime 4. I am attaching a link to a topic that discusses this issue of low volume: VirtualDJ - VDJ 2021 with Denon Prime 4
