Correct. Built in mic has gain on or off using the recording level switch. Front most of the three on the right side of the recorder. Press switch toward body of the recorder. It will announce AGC on or off.

The built in microphone is limited to just auto gain? _______________________________________________ Plextalk mailing list Plextalk@lists.hodgsonfamily.org https://lists.hodgsonfamily.org/listinfo/plextalk
