Enhanced Security

The DS-3400 is a digital voice recorder that records in the Digital Speech Standard Pro (DS2) audio format. It uses SD memory card flash memory as removable storage, so the user never has to leave the recorder with a transcriptionist - just leave the memory card. By using larger-capacity SD memory media (up to 16GB), the user has the option to dramatically increase the potential recording time of the DS-3400. The DS-3400 offers the ability to edit files in the recorder. File-editing options include appending files, overwriting a section within a file, or inserting recordings into an existing dictation file. Since the DS-3400 is also a mass storage device, it can be used as a USB "thumb drive" to transfer files from one computer to another.

The device also offers a Device Lock function to guard against unauthorized access. Once configured, a user-generated numerical password must be entered to enable the device. This provides a measure of protection in the event the device is left unattended or lost.

The bundled DSS Player Pro 5 for Windows® and DSS Player for Mac® software enable the downloading of dictation files to a computer, where they can be archived and where further file editing can be performed. The applications also enable file splitting and joining. DSS Player Pro 5 for Windows also provides an interface for voice-to-text applications such as Dragon NaturallySpeaking® Preferred.

The DS-3400 is an Olympus Professional Dictation Device. As such, technical support for the recorder and its associated software is provided solely by authorized Olympus Professional Dictation Products dealers.

    Simple but works very well

    Posted by Kendall Cortez on May 11th 2023

    As a journalist, I'm constantly on the move and needed a mic that recorded in good quality but was also compact. This mic is absolutely perfect, especially for this price. It's small and lightweight, making it easy to transport and use on the go. Despite its small size, the sound quality is excellent, allowing me to capture clear interviews and discussions on my laptop from wherever. I'd highly recommend this mic even just for regular use and not traveling, but if you travel and need a mic this is a perfect solution I'm so glad I found!
