PreRecord Buffer ‡ – drop-down box for setting the duration of the FlashMic’s pre-
record buffer in 1 second increments from zero (off) to 10 seconds. (Set to OFF in
example) See section on PreRecord Buffer, page 36 for more information.
Record Volume/AGC ‡ – If the AGC box is checked (as in this case), the Record
Volume drop down box will be greyed-out. With this setting, the AGC circuit is turned
on, and no fixed record level is set.
If the AGC box is unchecked, the Record Volume drop-down box permits setting of
the record level in 5dB increments from 5dB to 40dB.
See Adjusting Record Level, page 13 for more information.
High Pass Filter ‡ – FlashMic includes a 100Hz 12dB/octave high-pass filter
which can be switched in and out.
Backlight ‡ – the display panel backlight in FlashMic can be set to be permanently
on or off, or to “Energy-Save mode”, where the backlight illuminates for a short
period when a button is pressed. The battery life will be noticeably shortened if the
backlight is set to “Always On”.
