Voice Recorder Sony ICD-PX470 Black:The Sony ICD-PX470 is an appealing solution to make cutting-edge recordings of various different kinds of sound. First of all, it is equipped with a very sensitive stereo microphone (the S-Microphone), which also adjusts to even the smallest sound sources. When you’re recording a single voice, Focus mode captures a narrow field of sound from one direction. Filter out low-frequency background noises when you record by engaging the low cut filter. Recording can be saved in the standard MP3 format as well as in the advanced LPCM standard in which the files are larger but capture much more detail. Make sure that the audibility of every word is captured using Clear Voice technology which cleans up the signal even more for improved clarity.The key features of the Sony ICD-PX470 digital recorderA sensitive S-Microphone stereo microphoneAdjust the microphone to focus on the direction requiredBackground noise reduction mode and voice highlightingRecording in LPCM or MP3 formats4GB of internal memory with up to 32GB via a micro SD card slotUSB port for direct connection to computer or notebook ...Parameters and Specifications:Memory:Built-in: 4GBBuilt-in microphone:Stereo microphoneRecord Format:MP3 / LPCMBattery Type:2 × AAAInterface:Headphone jackMicrophone InputUSB connectionMicro SD slotRecord function:Scene SelectionLow-cut FilterOptimised Voice RecRecorded voice recording (VOR)Record trackingPlayback and editing functions:Digital treble adjustment (speed control)Noise suppressionDigital Voice UpEasy searchTrack markingErase, Protection, PartitioningMove file, Copy fileDimensions:38.3 × 114.2 × 19.3mmWeight:74g
