REVIEWER’S GUIDE

Understanding the 24-bit/192kHz Capability
Digital audio quality depends on bit depth and sample rate. Bit depth refers to how
many bits of information are available to represent each sample, a factor that trans-
lates to dynamic range. Sample rate is how many times per second the sound is
sampled. The standard for today’s audio CDs is a sampling rate of 44.1kHz at a
resolution of 16-bits per sample. The Revolution 7.1 supports sampling rates up to
192kHz and resolutions up to 24-bits—the highest available in both the professional
consumer markets.
