The PCI Express CM8828 TXCO stereo HD Audio sound card PRO is a high quality multi-channel audio processor that not only an Intel HD Audio specification compatible audio single chip, but also can be a controller which can connect HDA codec. 

It supports up to 10 outgoing channels and 6 ingoing channels. The 10 outgoing channels are composed of 2 playback DMA’s, which are multi-channel DMA (24 bits, 8 channels, 192k), Headphone out & S/PDIF DMA (each 24 bits, 2 channels, 192k). 

The 6 ingoing channels are spread in 3 recording DMA’s (up to 24 bits, 192k). It can be built in the home audio electronics or personal computer to provide high fidelity sound and become a professional audio processing center in your life.
