Frequency Response:.................................20-20,000 Hz + 0, - 1dB
Transient Response:............................Onset of steady tone: 1.6 dB
                                                 overshoot at 0.05 seconds,
                                settles to within 0.5 dB within 0.1 second.
Accuracy:............................+/-0.4 dB per step maximum, +/-0.15 dB
                                                           per step typical
Input Impedance:
  IN1:...........................................................1 Mega Ohm
  IN2:.............................................................100K Ohm
Sensitivity:...............................................See table below.
                           Sensitivities specified in the table are for the
                         threshold of the next to last LED to light (0 dB).
                               Lowest level LED thresholds are 18 dB lower.
