Gnome P. User Guide
●
Set current date/time and recording parameters considering the recording conditions
(see 7.3.3). If you wish, enter (set) a PIN code to protect access to Gnome P settings
(see 7.3.2).
●
If necessary, attach external microphones (see 5.2).
Attention!
Before connecting the voice-recorder to a PC make sure that PC case is effectively
grounded. Connection to ground is strictly recommended if you intend to connect the voice-
recorder to a PC and external power supply and/or external signal source at the same time.
Attention!
It is not recommended to connect several voice-recorders Gnome P to a PC at one
time. Before connecting second voice-recorder you should disconnect the first one.
6.3. Recording
6.3.1. Recording hints
To obtain high-quality audio recording we recommend you to follow these guidelines:
1. It is not advisable to perform audio recording while the voice-recorder is USB-con-
nected.
2. Use stereo recording without compression at 16 kHz sampling rate if possible. Ste-
reo recording provides speech intelligibility even in noisy conditions.
3. Mono recording allows you to record longer sound signals.
4. To prevent useful signal loss, use Voice Activation mode only if input signal level is
stable.
5. Place microphones as close to the useful signal (speech) source as possible and as
far from the acoustic and electromagnetic noise sources as possible. The closer the
microphones are placed to the acoustic signal (speech) source, the smaller is rever-
beration (echo) and the higher is the gain level and speech intelligibility.
6. External microphones are more sensitive and at the same time can be easily con-
cealed (under a jacket lapel, shirt collar, on the cuff). During stereo recording extern-
al microphones should be placed at least 15 cm from each other.
7. Try to place the microphones in such a way as to avoid vibration, impact and rubbing
against other surfaces.
8. Avoid permanent contact of the voice-recorder box or external microphones with
rough surfaces (such as table plate, car, concrete structures).
9. Note that if mono recording is enabled, only left channel data will be recorded.
10. To conceal the sound recording process and/or avoid record suppression by special
devices (HF generators) it is advisable to use the internal microphone.
6.3.2. Manual recording start/stop
The recording process can be started/stopped both manually and automatically. To start
recording manually, set the switch on the recorder body (N2 in Figure 5.1) or on the remote
control unit to the ON position.
To stop the recording, set the switch to the OFF position accordingly.
6.3.3. Voice Activated recording
To perform voice activated recording, first enable “Voice Activation” in the “Record set-
tings” window of Sound Manager Gnome P software (see 7.3.3) and specify the required
VA start/stop threshold, then set the switch on the recorder body (N2 in Figure 5.1) or on
