Pioneer KRP-M01 Digital Media Receiver for KRP 500 / 600

I don't know that but maybe 3 hdmi output for south asia region...for 4 hdmi output for Europe
region....that's my best guess...I got the 4 hdmi so for Europe region but still can be use for
any KRP500/600 panel....

The potential flexibility advantage of going for an external media receiver immediately becomes apparent with the 500A's connectivity. For the KRP-M01 receiver is stuffed with connections to cater for pretty much every scenario. There are four HDMIs, for instance (three on the rear, one on the front), a USB input, a front-mounted D-Sub PC port, two common interface slots, three SCARTs, an optical digital audio output, a component video input, an Ethernet port, and a satellite connector alongside the normal antenna connection.

My KRP-M01 has "PURE" mode....same as stated in www.trustedreviews.com

"
Probably the most ‘dreamy' feature for AV purists, though, is the 500A's new Pure AV mode. This basically bypasses as many of the usual video processing shenanigans between the source and the screen as possible, enabling the picture to look almost precisely how it appears at source. We have absolutely no doubt whatsoever that provided it works well, this purist's feature will sell a healthy number of 500As all by itself."
