While recording, the selected file type will be indicated by an icon above the
corresponding microphone VU meter on the dashboard:
(ultrasonic WAV),
(acoustic WAV), and/or
(ultrasonic ZC).
SELECT THE MICROPHONE
The options available for the microphone change depending on the
Acoustic sample rates let you choose between:
•
Monaural recording, using the acoustic microphone connected to side A;
•
Monaural recording, using the acoustic microphone connected to side B;
•
Stereo recording, using acoustic microphones connected on both sides.
Ultrasonic sample rates only permit monaural recording from the ultrasonic microphone
connected to side B.
ACOUSTIC RECORDING SETTINGS
Gain
Gain changes the amplitude of the recorded microphone signal. You can adjust the gain of
each of the two acoustic microphones independently, in increments of 3dB up to +15dB. Use
the up/down arrow buttons to select
Gain
and then use the left/ right arrow buttons to
choose the gain that you want, a higher dB represents an increased amplitude.
A higher gain setting will pick up more sounds, but the recording will become distorted when
there are loud noises. Typically, 3dB is the recommended setting.
Handy tip:
When using two acoustic microphones, you can set one channel to a low gain
and the other to a high gain to record both loud and quiet sounds with good quality.
Otherwise, make sure the gain settings for side A and B are equal.
Maximum File Time
The maximum file time represents the maximum length of a file and can be up to 1 hour.
When a recording is triggered, the recorder will record files up to the specified length in time
