TASSSR250N - TASCAM SS R250N Networkable SS Recorder SD or SDHC or SDXC or USB FLASH 1U Image 2

The SS-R250N is a networkable solid-state recorder/player with a variety of remote-control options for professional applications like in broadcast studios or fixed installations. It records in WAV and MP3 format to SD/SDHC/SDXC and USB flash memory. Since the recorder is able to connect to an FTP server via a network, it can upload recordings automatically after a recording has been finished or download files for playback. Time synchronisation via SNTP is also possible.

With its dual SD card slots, the SS-R250N offers more security to your valuable files compared to conventional recorders. During recording, backups can be created on the second memory card, or the recorder switches to the second card as soon as the first card runs out of memory. The unit also closes files automatically in case there is a sudden power outage during recording to avoid loss of the entire recording session.

The SS-R250N can be controlled in a variety of ways: The RC-SS150 remote control offers a convenient interface with a colour LC display and 12 keys for flash playback. There is also a dedicated app available for iOS and Android devices that can control transport operations and various settings. Or you can integrate the recorder into existing environments using serial or parallel control.

For audio connections, the SS-R250N is equipped with balanced and unbalanced analogue inputs and outputs as well as SPDIF coaxial and AES/EBU digital I/O with sample rate converter. An optional Dante interface card offers two-channel input/output for Dante audio networks.
