The Olympus DS-9500 is a digital voice recorder with ODMS Release 7 software designed to deliver convenient, secure, and versatile voice recording for office workers, interviewers, electronic news gatherers, and A/V technicians. Its dual-microphone setup incorporates selectable modes that modify the directivity and noise cancellation parameters to suit different environments. An integrated three-layer pop filter reduces wind noise picked up by the mic, which offers adjustable sensitivity and voice-activated recording. A 3.5mm mic input is provided for connection of a preferred external mic. Use the backlit 2.4" color TFT LCD, cursor pad, and programmable buttons to configure settings such as recording format, indexing, and more. The DS-9500 can record in PCM (WAV), MP3, DSS, or DSS Pro formats to the 2GB of internal memory or SD/SDHC cards up to 32GB in capacity. AES 256-bit encryption is offered with the DSS Pro format. Monitor through the built-in dynamic speaker or connect your headphones to the 3.5mm output. Files can be transferred over USB 2.0 or Wi-Fi.
