I'm afraid I have to respectfully disagree with Wayn'e advice to you regarding the Y/C PLUS versus the Y/C++. First let's settle a very important misconception about the INTERNAL connections that the Y/C PLUS makes to the Toaster; The Y/C PLUS uses unshielded ribbon cables to connect to the COMPOSITE input taps that are on the edge connectors on the Toaster circuit board. These connections share the same signal path as the external BNC input connections to the Toaster. There is absolutely NO ADVANTAGE to using these edge connections as opposed to the BNC connectors. To the contrary, because the Y/C PLUS is using UNSHEILDED cables to pass the video signal to the Toaster, there is more likelyhood of interference to the video signal from adjacent components inside the computer such as the power supply and fan. Speaking of power supplies, smith Audio Visual recommends a larger unit than the one that comes standard on most Amigas for proper operation. Regarding Wayne's statement about the Farujia circuitry; The component the Y/C PLUS uses to do the comb filtering is nearly identical to that used by both the PCA from DPS and the Prime Image Y/C++. The Y/C PLUS board was indeed designed and manufactured by Farujia labs, but the comb filtering is "adaptive" just as the others are. I have compared chromanance and luminance specifications using test equipment and industry standard test patterns on the Prime Image unit as well as the Y/C PLUS and could not determine any specific technical performance advantage for either unit. After all my comparison shopping, I chose the Prime Image unit because of the following advantages; Being an external unit, it didn't require power from my computer or take up valuable slots in my 4000. The Toaster's inputs are individually capable of using either Y/C OR composite via easy to reach external switches. The Toaster's program output is continuously available in three different video signals: Y/C, composite, and component (Switchable between MII and Betacam). Hope this info helps.
