Ground noise rejection
Signal-to-noise ratio (dB) = SNR is a measure of the difference in level between the full scale output and the output with no
signal applied. (No Auto-zero or Automute function is employed in achieving these results).
Dynamic range (dB) = DR is a measure of the difference between the highest and lowest portions of a signal. Normally a
THD+N measurement at 60dB below full scale. The measured signal is then corrected by adding the 60dB to it. (E.g. THD+N
@ -60dB= -32dB, DR= 92dB).
THD+N (dB) = THD+N is a ratio, of the rms values, of (Noise + Distortion)/Signal.
Channel Separation (dB) = Also known as Cross-Talk. This is a measure of the amount one channel is isolated from the
other. Normally measured by sending a full scale signal down one channel and measuring the other.
