    I just bought a Denon AVR2105 but I read something that worries me. I want it to switch component hi-def inputs.

    I see the component bandwidth is 30 MHz, but I read somewhere I need 50Mhz for 720p and 1080i. Am I going to have to return the amp? :(

    Please help..

    The Component Inputs/Outputs of the USA 2105 have 100MHz bandwidth. Be a bit strange if the UK/Euro version didn't, although it's manual does say 30MHz. Wonder if that's a mistake??

    Technically you can get away with 30Mhz bandwidth for HiDef but the higher the better.

    OK, thanks. Really appreciate the help :)

    Could you tell me what the symptons of not having enough bandwidth would be? Would there be a decrease in picture quality?

    The newer 2106 apparently has 100Mhz bandwidth on the component inputs (according to the website). I could swap my 2105 for the 2106 but it will cost me another £150 which I don't really have. Would it be worth swapping, considering that I bought it primarily for use with high-def component displays?

    It might be worth sending an email to Denon UK to clarify just exactly what the 2105's component bandwidth is (seeing as the US Model is 100Mhz, yet the UK/Euro Model manual says 30MHz).

    Thank you :) An interesting read.

    Unfortunately I don't have any high def sources that I can use to test it out.

    I just found something that says 720p requires 37Mhz, and 1080i is 50Mhz. I think 720p is good enough for me so I'll probably keep the amp. I'm sure something will make me change my mind when it's too late, but that's just my life :rolleyes:

    Thanks for the help!

    with lower bandwidth the picture may tear at the top of the screen when bright things are displayed (higher freq.). it happens to me with my CA Azur sometimes, but i think you'll get away with it :).

    Thanks everyone.

    Just to let you know, in case anyone is interested:
    I got everything set up and ran some 720p and 1080i games from my Xbox through the 2105 and could not notice any problems with the screen, so I'm happy.

    I did finally get an official response from Denon over a week after I contacted them, (maybe I should have called instead of emailing) and it was:
    After I had specifically asked them about the 2105 that I had just bought.

    Well, thanks to everybody on the forums for the info :clap:
