i dont know

I pay for it but a nothe co. put it in

terrible design

i would not recommend this adapter at all. it has a built in line input gain which causes a ton of distortion in the system. after switching to the PAC equivalent my system sounds amazing as it should be. best way i can describe it is that when you plug a cellphone into a aux port and turn it way up you get the distortion at low levels and pretty much any level. that is what this device does.
