Pro-Logic II chip???

[Gamereviewgod]

After searching for about an hour, syphoning through god-knows how many sites, and reading a whole lotta press releases, I believe there is a "chip" upgrade for my reciever to accept Pro Logic II. It currently handles 5.1, DTS, and Pro Logic. For the life of me I can't find this so called "chip" anywhere. Hell, I don't even know exactly what it is that I'm searching for.....

It could very likely be a firmware upgrade that would be done at the service center for your brand of receiver. Call the company and ask them.
