[QUOTE="DACMan1, post: 2431, member: 112"] Different remotes have different timing specs and packet sizes. The software from elector has a remote setup part, where you press the button on the remote and thn assign it to a function on the preamp. Its designed for RC5 remotes, but only one out of 5 remotes I tried works at all. What remote are you configuring it for? One of the advantages of using 2 PGA's in differential mode is that you can the better PGA2311 and still have adequate voltage swing (4.2Vrms before distortion increases) to not need another gain stage. I don't think the DAC you use is balanced?, so you could use a DRV134 or a OPA1632 to do conversion to balanced. I use a OPA1632 for unbalanced inputs, then convert them before they go to the PGA. It should be easy to modify most amps to accept balanced inputs with just a couple of extra resistors. [/QUOTE]
