Hi Jack

Perhaps I've been unclear, but downmixing is not the same as downsampling. In your case, downmixing is reducing 6 channels of sound into two, whilst retaining the original bit rate and sampling frequency (ie 16/48 for decoded BD discs).

Downsampling would be taking , say, 96kHz material and changing it to 48kHz.

So in your system, you want the G68 to do the job of changing 6 channels into two. The HD621 will actually upsample the 6 channels' worth of 16/48 content from BD discs (or DVD-A discs) to 24/96 and it will apply apodising as part of that process.

Hope that's clearer.

Cheers
