Professional Digital Recorder NS-16-004 — IntellThing

The tape recorder is fulfilled in strong metal tank and intended for one-channel and two-channel record of the audio information with compression on method ADPCM or without it.
As signal sources can be used built in and / or external electronic microphones, and also linear outputs of peripherals. Tape recorder power supply can be carried out from the built in accumulator or the external power supply.
Two LED indicators display operating modes and a state of a charge of the accumulator. Inclusion on record is made by the switch or under the timer program. Handle and data transfer on the personal computer is made on interface USB 2.0 by means of a package of the applied software.
