Parrott Translator™

For highest speech recognition accuracy, a factory-adjusted current mirror amplifier provides large microphone signal swing without distortion. High pass and low pass filtering assures optimum voice frequency response. Isolation network prevents legacy sound cards from voltage starving the microphone. Batteries may be added to overcome low DC mic bias in certain notebook computers. If batteries are needed, the Translator housing will accept two AA cells; battery life will exceed 15 months.
