Where are EQ settings in Synapse 3 or Razer App Engine?

I have recently purchased a Kraken X USB and want to tweak the EQ as it's currently really bassy out the box. I have seen threads with different EQ settings being applied in different ways (most look like they're being set in older versions of Synapse) but I literally have no idea where I can set these EQ settings? Can anyone shed any light on how I can change these EQ settings on the latest version of Synapse? Happy to get any additional software if needed!
