Hi, guys. Igor has built an incredible mastering controller for me which uses the PGA2320 for gain control and I must admit it sounds amazingly transparent to my ears. Soon I intend to do a very careful blind shootout of it against my Cranesong Avocet, which as you may know uses relay-controlled switched resistors. Texas Instruments is particularly cagey about what sort of switches they are using to switch their resistors, but they certainly are a lot better than your "classic" 4066. Has anyone else here built any circuits using the PGA2320 and got sonic comments about this remarkable chip? It seems to me so far you'd have to have a VERY transparent monitoring chain to discern any issues with this chip. That's what I've got here, so I just have to switch between the Avocet and the PGA-based box and compare their sonics.Igor said:Helios EQ is not a bad idea at all. At least there's no any diy-able here.....
Well, let's go for Helios EQ. I will check what is possible to do with inductors and Elma switch.
The make-up amp on Helios card is not capable of driving the 600 ohm line. So, unbalanced? Line receiver/driver chips? Nope...
And....just as a thought, it can be done with Neve class A make-up amp (second half of BA-283) and 31267-like line input trafo....
I thinking about fully automated summing mixer based on PGA2320 chips insteaad of faders. Bit complicated and costy...
Well, Helli've... Nevious....whatever....
