Tips for making better recordings
While making recordings is very simple with the D1000X, there are a few things to think of in
order to obtain the highest quality.
The recording level indicator, shows the actual signal level at the analog-to-digital converter
(ADC). The indicator consists of eight LEDs. There are five green LEDs for the lower signal
levels, two yellow LEDs for higher levels and one red LED indicating that the maximum
signal level has been reached or exceeded. If the maximum signal level is exceeded, the
recorded signal will be distorted. Obviously, this condition should be avoided.
The input gain control located on the front panel should be adjusted to keep the level indicator
in the green and yellow areas. It is recommended to set the input gain control at a relatively
low gain. This will keep the noise at a low level, resulting in a high dynamic range.
If the heterodyne or frequency division signal is monitored through the loudspeaker, this
sound will also be recorded by the detector, even if the sound source is the original signal (a
MIC recording is made). Enabling the highpass filter will attenuate these signals as well as
other low-frequency signals, but will not eliminate them completely. For this reason it is
recommended to use headphones rather than the built-in loudspeaker while making the
recordings. When the loudspeaker is used, always use a low Volume setting. Since the
D1000X microphone is very sensitive, it is possible that the heterodyne or frequency division
signal is recorded at a low level even if headphones are used.
In many cases, you may not wish to save every recorded file. Choosing PROMPT as Save
mode will give the option of saving or erasing the file immediately after the recording has
been made. Another way to do this, which is quicker if you know that you will want to keep
most of the recordings, is to use the AUTO Save mode and manually erase the few files that
you do not wish to keep. Manually erasing the last file is made with the ESC key when the
detector is in the standard mode.
If you wish to erase sound files on the CF card, use the ESC key on the detector to erase
single files as described above or format the card in the detector or in a PC to remove all files
on the card. Erasing files manually from the computer, while the CF card is in a card reader
should be avoided. In order to erase all files on the card, the preferred method is to format the
card.
