The board also comes with many internal connectors. CD, video and modem connectors are available, as is a CD S/PDIF connector to take digital audio straight from the CD/DVD drive. Of other commonly available audio cards, only the SoundBlaster Live! Platinum has this connector. The Santa Cruz also accepts hardware wavetable add-on boards, such as Turtle Beach's Cancun FX Roland-certified expansion. There is a mysterious expansion connector on the back of the board. Probably so Turtle Beach can add daughter cards for higher-end products.
