The “Gnome-P” recorder allows for long-term, high-quality stereo or mono audio recording with or without compression, using built-in or external microphones, to internal memory. Manual and automatic adjustment of the input signal level and starting/stopping recording (by signal level or at a set time) are possible. Operational copying of recorded information from the recorder’s memory to another digital medium is done in the form of WAV audio files (PCM 16-bit). The built-in battery is charged from an AC/DC 100-240 V/50-60 Hz network charger or from a computer’s USB interface.
Distinctive features:
-
High recording quality with minimal dimensions
-
Long recording duration
-
Resistance to electromagnetic interference
-
Digital signature to protect recorded information from modification
