Higher bit resolutions (that is, longer word lengths) translate into increased dynamic range — the degree of
variation between the softest and loudest parts of a signal you hear. CD technology uses 16-bit resolution; this
provides the equivalent of approximately 96 dB of dynamic range. Newer technology allows higher-resolution
signal of 20- and 24-bit. In theory, the dynamic range of a 24-bit signal is 144 dB, which actually exceeds the
capability of human hearing. The DMX-R100 utilizes 24-bit converters throughout and is capable of carrying
and passing full 24-bit signal without any compromise in functionality. Even if the final output of a project is
destined for 16-bit CD, there is a strong argument for using 24-bit resolution in the production stage so that
when the signal is converted downward (usually with the addition of dither, or low-level noise, to reduce audio
artifacts), maximum fidelity can be retained.
Another difference between a digital console and an analog one is that a digital console has the capability of
combining analog inputs with digital input signal, and, conversely, outputting a digital data stream as well as an
analog output signal. (See Figure 5)
