The .1 is a bass channel, but it's not quite the same thing as a subwoofer channel. It's band limited but also has a 6dB gain difference from the main channels, so it can carry higher levels without saturating.
The AV amp, however, doesn't just route this channel straight to the sub - instead it may mix in low frequencies from the main channels and/or route some frequencies from the .1 channel back into the main mix. For this it does need the A/D converter. For what it's worth, the DSP-A1 does have pre-out/power-in jumpers, maybe I should try these - though that would mean using the SB3's digital attenuation which means it's not really a fair comparison. -- AndyC_772 ------------------------------------------------------------------------ AndyC_772's Profile: http://forums.slimdevices.com/member.php?userid=10472 View this thread: http://forums.slimdevices.com/showthread.php?t=35642 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
