how can i utilize the icbm if i want use the 7.1 inputs on the rx-2500? there are only the usual front center surround outputs on the dvd-750 yet i plan to utilize r&l front-center-r&l surrounds-r&l rear surrounds and POSSIBLY rear center speaker(the 2500 has the capability of even adding two!more presence speakers for a total of 9 channels) and of course a powered sub-the icbm manual doesnt really address this unless i consider the 750 a processor and the 2500 a 7 channel amp but even then there doesnt seem to be enough inputs outputs to do this even with y connectors unless iam reading the icbm manual wrong-help!i"m about to buy all the above but if it cant be done then ill drop dowm several models and just get a 5.1 receiver thaks rwb
