Hello all,
I am building a pair of 4 channel amps and a single channel amp for car audio use. Each of the 4 channel amps uses one of these 260-2 units, and the single channel will use a 480-1. This is my first time building amplifiers, and I have plenty of questions about many things, but the roadblock I have currently is doing the differential to single ended input conversion. The car audio DSPs only have single ended output, unfortunately, so I ordered the 1612 OP amps to add to the boards. The user's guide is not very clear, unfortunately, as they show the U1 and U2 sockets, but not U3 and U4, where the op amp and resistor are added. Further complicating the matter is that U1/U3 and U2/U4 are not identical, so it is unclear to me based on the guide what exactly I should be doing. Like I said, this is my first time and maybe it is clear what needs to be done by those with more experience. I am attaching a photo of the sockets, would someone be able to circle and draw arrows where I should be moving the resistors?
Thank you!
