I thought this came up before. Far as I know they are the same. I can’t tell any difference but haven’t done a test. That would mean that QU Pres are the same since boxes work with it. That’s what I love about AH. I can use my AR2412 084 and AB168 with my QU16 or GLD80.
Someone told me the preamps in the stagerack AR2412 sound a but more “relax” than the onboard ones. But I can’t immediate hear a difference. Even with a DPA D:Facto lineair mic on a extreme lineair P.A. system. So, I would like to have a confirmation of an expert. So do I understand it well that Nicola A&H confirms that the preamps of the onboard GDL mixer are the same in quality as the ones in the stagerack AR2412?
