yes, the center and sub channels are both mono, but the center channel will only work with 5.1 channel encoded audio(i believe that the sub channel does the same)-- that tells the soundcard to send a signal to the center channel.
it is also the same for the rear channels, but those need at least 4 channel audio to work. the front channel is the only pair that will work with all audio sources.
another way to get audio out of the card would be to use some y-adapters to split the stereo front signal output to the different amps.
