I just got a digital combo amplifier and the only outputs it has are USB and a headphone jack. I am trying to record it by using a 3.5 mm to dual 1/4 inch adapter and plugging it into my interface. The USB out does not work well because I already have an audio interface.
My question is do I need to engage the Instrument level button on my interface?
I am not familiar with how line/inst level and things of that nature work. I read somewhere that impedance can affect sound quality. I want the best quality I can get although this isn't the optimal setup.
Hope this is not too confusing, Thanks.
