2. Zero Bit Detection
A circuit in a D/A converter that monitors the digital audio bit stream. upon encountering all bits low, or zero bits, the output of the D/A is disconnected from the preamp. This improves the signal-to-noise ratio specification.1

3. Zero Crossing-An analog waveform consists of two alternating voltage polarities (positive to negative to positive...etc.). The point where the polarity changes from positive to negative, or vice versa, is called the zero crossing. When looping a wave or editing two waveforms together, this is the ideal location for the splice as the levels of the two waves are both at zero. This eliminates the possibility of clicks or pops created by mis-matched levels, and makes for a smooth sonic transition.
