What is the VCVA (Variable Control Voice Actuator)?

In order to improve performance in long recordings, DS-150 is equipped with a voice activated recording function (called VCVA by Olympus). If incoming sound level is less than set level for more than 2 seconds, DS-150 automatically stop recording. When incoming sound level becomes more than set level, DS-150 automatically starts recording. VCVA sensitivity can be set for effective use in each environment. (When VCVA is on, the beginning of recordings might not be recorded slightly. Therefore to use a message for voice recognition, please set VCVA off.)
