Trouble connecting Philips M1X-DJ to Ipad Pro (IOS 14.8.1)

Hi there! I’m new to this forum… Recently we were gifted a Philips M1X-DJ unit for my son. I would like to connect it to my Ipad Pro, but unfortunately, my ipad does not recognize the device… we use a MFI certified adapter to get it plugged in ( the m1x only has the old lightning connector), but no response whatsoever. It even can’t be used as just a soundbox… does anyone has any experience using these two systems together? The M1X seemed to work just fine with the former owners iphone… (with lightning connector…). My very old ipad also is able to stream sound to the device, but the old IOS will not allow us to install the djay app…

Thanks in advance for trying to solve this puzzle with me…
