5. 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).

6. Dynamic range (dB) - DNR is a measure of the difference between the highest and lowest portions of a signal. Normally a

THD measurement at 60dB below full scale. The measured signal is then corrected by adding the 60dB to it. (e.g. THD @

-60dB= -32dB, DR= 92dB).

7. THD (dB) - THD is a ratio, of the rms values, of Distortion/Signal.

8. Stop band attenuation (dB) - Is the degree to which the frequency spectrum is attenuated (outside audio band).

9. 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.
