     The high performance PC has taken the living room by storm as high performance home theater PC builds continue to become an integrated part of your home entertainment setup.  The recent release of C-Media's CMI-8788 chipset brings the same high quality sound processing technology found in a top end home audio setup right to your PC.  HT Omega's Claro brings you the CMI-8788 at a very attractive price.  Let's see just what this sound card brings to the table.

     HT Omega may be a new name to many of us but they are a US based company specializing in multimedia hardware and peripherals.  New or not, the list of supported sound formats is most impressive.

     HT Omega also does a nice job of displaying information about the most desirable of these sound formats on the back of the packaging.  In a market dominated by the X-Fi cards the Dolby technologies offered in the Claro compete directly with Creative's cards costing twice as much.  With this focus on sound quality over PC gaming; both the Claro and HT Omega's Striker 7.1 cards offer an exciting option for crystal clear high end audio.

     The C-Media Oxygen HD CMI8788 chipset is the core of the Claro bringing a true wish list of audio formats to the table in a true 8 channel super high performance PCI audio processor.

     "The CMI8788 is a high quality PCI 32-bit multi-channel audio processor that 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. It supports up to 12 outgoing channels and 8 ingoing channels. The 12 outgoing channels are composed of 3 playback DMAˇ¦s, which are multi-channel DMA (32 bits, 8 channels, 192k), S/PDIF DMA (32 bits, 2 channels, 192k), and front panel DMA (16 bits, 2 channels, 48k). The 8 ingoing channels are spread in 3 recording DMAˇ¦s (32 bits, 192k), namely recording A, B, and C DMAˇ¦s. The architecture of recording is a unique point of CMI8788 that makes the recording become the most flexible for the users. The details of the recording mode selection will be explained in the later sections.

     The CMI8788 can co-work with all the popular codecs nowadays from I2S codecs with over 120dB quality to the usual AC97 codecs. This ability gives customers the flexibility to design their products. The I2S, AC-Link, 2-wire master bus, and SPI interfaces are used to transfer audio data and control data between the CMI8788 and codecs. To facilitate the connection with the existing home audio electronics, the CMI8788 has incorporated the S/PDIF transmitter and receiver with 192k sampling rate in it." ~
