If an accessory monaural microphone is plugged into the DS-2200 without setting the recorder to Monaural External Input, the accessory microphone will not work and the built-in recorder microphone will remain enabled.
To set a DS-2200 for use with a monaural accessory microphone, use the following procedure:
- Insert the accessory microphone plug into the recorder EAR/MIC jack.
- Open the recorder menu and use the REW or FF buttons to scroll to EXT. INPUT.
- Press PLAY.
- In the EXT. INPUT list, use the REW button to scroll down to MONAURAL INPUT.
- Press B>PLAY and then STOP to close the menu.
This setting must be entered every time a monaural microphone is connected or the recorder is powered up. Disconnecting the monaural microphone discards the setting. MONAURAL INPUT status cannot be saved as a default setting.
