Hear every detail: sound your best with the new digital voice recorders from Sony

Press release   •   May 29, 2013 12:18 BST

From rehearsal room to boardroom – two new digital voice recorders by Sony ensure that each note and every word are heard with CD quality.

Slipping easily into a pocket or bag, the slim, light ICD-SX1000 and ICD-SX733 are perfect recording partners when inspiration strikes.

Both models feature a new three way S-Microphone System that picks up music, meetings and memos with pinpoint precision. ‘Stereo’ mode ensures smoothly-balanced, hi-fi quality recording of instruments and voices – great for band rehearsals and song-writing sessions. Or switch to ‘Zoom’ and focus precisely on interview subjects located on the other side of the room.

The range-topping ICD-SX1000 is capable of high-resolution recordings at 96.1kHz/24-bit, capturing solo instruments, ensembles or voices with exceptional clarity.

The SX1000 also adds Sony’s S-Master Full Digital Amplifier that reproduces the subtlest nuance of every performance. Originally developed by Sony for hi-fi and home cinema products, S-Master technology has been optimised for mobile devices, reducing digital distortion for smoothly detailed studio-quality sound.

A choice of eight Scene Select modes on both recorders ensures optimum clarity, whatever you’re recording. Pick ‘Music’ for a wide, balanced frequency response with every instrument heard clearly. Select ‘Voice Memo’, ‘Meeting’ or ‘Interview’ for clearly-intelligible speech without annoying low-frequency booms, pops and rumbles.

A generous 16GB of on-board storage (ICD-SX1000) gives space for almost a week’s worth of non-stop recording (159 hours at MP3 192 kbps). Need more space? Slipping in an optional microSD or Memory Stick Micro (M2) card expands recording memory further to ensure you’re never lost for words. The inbuilt lithium battery offers plenty of stamina for those lengthy jamming sessions, recording non-stop for up to 19 hours between charges (Linear PCM 44.1kHz, 16 bit).

Both recorders also double as handy music players, replaying files in MP3, AAC, WMA and WAV formats. Just load up with your favourite tracks and enjoy through the supplied stereo earphones or on-board speaker.

Sound Organiser PC software comes as standard and simplifies transferring, editing, managing or burning your files to CD.

The new ICD-SX1000 and ICD-SX733 digital voice recorders from Sony are available in the UK from May 2013.
