Extremely small recorder, concealable almost everywhere
The REC-40D is a tiny digital micro recorder capable of working for long periods, even in extreme audio monitoring situations. Concealable almost everywhere, the device can record continuously for 40 days in a row before running out of its 32 GB memory (interchangeable Micro SD card supplied). This product has been conceived and marketed exclusively by Endoacustica Europe. It is designed to fully satisfy all those audio recording requests that have persisted over time. The recorder functions as a real "black box" for the recovery of audio data of specific relevance. The basic version of the micro recorder can be powered with direct current from 5 to 24 Volt, which makes it a versatile device to be used in static or mobile environments such as cars or trucks. The REC-40D can also be customized according to specific needs. For example, the power supply can be replaced with lithium batteries for an even simpler and faster installation. That’s just one of the many customizations that can be made by our technical experts. This is a plug-n-play product and starts recording automatically when powered.
High-performance Knowles Microphone
The highly sensitive Knowles microphone of the REC-40D micro recorder can capture sounds up to 12-15 meters away without losing quality and listening dynamics. The audio is recorded in MP3 format to offer immediate listening on any system or platform, without the aid of particular codecs or software.
Memory support with interchangeable Micro SD cards
The REC-40D mini voice recorder is equipped with a slot for inserting a Micro SD card functioning as memory storage. This ensures easy retrieval of information without removing the recorder from its installation location. Simply recover the memory card to immediately retrieve the acquired audio recordings, so you can listen and examine them later. The advantage of using removable memory cards instead of integrated memories is to make the device suitable to work 24 hours a day, 7 days a week without interruptions.
