    Accepts Sample Rates up to 48 kHz
    7 Biquad Filter Sections per Channel
    Dual Dynamic Processor with Arbitrary Input/Output Curve
        and Adjustable Time Constants
    0 ms to 6 ms Variable Delay/Channel for Speaker Alignment
    Stereo Spreading Algorithm for Phat Stereo™ Effect
    Program RAM Allows Complete New Program Download
        via SPI Port
    Parameter RAM Allows Complete Control of More Than
        200 Parameters via SPI Port
    SPI Port Features Safe-Upload Mode for Transparent Filter
        Updates
    2 Control Registers Allow Complete Control of Modes and
        Memory Transfers
    Differential Output for Optimum Performance
    112 dB Signal-to-Noise (Not Muted) at 48 kHz Sample Rate
        (A-Weighted Stereo)
    70 dB Stop-Band Attenuation
    On-Chip Clickless Volume Control
    Hardware and Software Controllable Clickless Mute
    Digital De-emphasis Processing for 32 kHz, 44.1 kHz, and
        48 kHz Sample Rates
