PreRecord Buffer ‡ – drop-down box for setting the duration of the FlashMic’s pre-record
buffer in second increments from zero (off) to 0 seconds. (Set to OFF in example) See
section on
PreRecord Buffer
, page 34 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 for more information.
High Pass Filter ‡ – FlashMic includes a 00Hz dB/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”.
