The 2 matching op-amp sockets (JRC 2114 op-amp), referred to as "I/V" sockets and are used by the headphones
and the third socket is call the "buffer" socket.
And all three sockets are used for the line-out (RCAs).
Why they are all three dual channel? I have no idea, but you need to have two channels for each socket.
Technically it's better to use two single channel op-amps per socket (less crosstalk?).
I'm currently using 6 AD797BR (SOIC) single channel op-amps in my Essence STX, the AD797BRs are soldered to a dual SOIC to DIP-8 adapter.
DIP-8 is a socket (removable op-amp)
SOIC need to be soldered
Hey, I've got a question about Opamps
I'm a little confused why there are three. I'm guessing that the third one up front is for something specific to the white and red out.
Is it that one is for the left channel, and one is for the right? If so, that leaves me a little bit confused. I know that some Opamps are single channel and some are dual channel, and that this card requires dual channel opamps. Now, since there are two.. doesn't that mean single channels would suffice?
As you can probably tell, I'm a bit lost. If the Opamps are dual channel - why do you need two? Is there a difference between dual channel Opamps and stereo? If so, is that why there are two - for the stereo? If not - do they work together in a manner akin to SLI or something, alternating signal? (I literally have no idea how they work lol) Or, is it that the red/white out uses one, and the headphone out uses the other?
I'm also a bit curious about the third one - what exactly does it do? I know its something spesific to the White/Red out, but I don't know what exactly.
I'm willing to learn, but I'm finding conflicting sources and it's difficult to nail down an exact answer. I hope the question is phrased alright - It's mainly my confusion as to why there are two of the same Opamp, and the difference between single channel and dual channel opamps.
Currently I'm looking at getting myself two LME49720NA and a LM6172IN, and giving them a whirl to see if they suit my tastes.
