Function 1
Select record mode (see table below).
Function 2
Pre record buffer adjustable from 0 – 10 seconds in 2 second
steps.
Function 3
Record volume, set to either AGC (Automatic Gain Control) or a
manual figure 0 –100.
Function 4
High pass filter (12dB / Octave @ 100Hz) on or off.
Function 5
LCD display backlight – on or off.
Function 6
Enable configuration in DRM85. When set to ‘Yes’, EXPERT mode
is engaged and functions 1-5 may be configured from the mic itself.
If this parameter is set to NO, then all presets are fixed and none
of the above settings can be altered from the mic.
BWF/MPEG file information can be entered in the fields on the right hand side
of the GUI. This will then be written into the extensions in the audio file to enable easy identification of recordings.
The headphone volume is not controlled by the GUI and not stored in a preset. It can be manually adjusted from the mic via a
rotary control.
FlashMic Manager PC/Mac software (supplied) allows FlashMic functions to be configured and stored in 9 user presets.
Presets can be set-up and then downloaded to non-volatile memory in the FlashMic via its USB port.
