SS-CDR250N
Networkable Solid-State/CD Audio Recorder
Flexible formats, multiple media, and automated FTP transfer
Smart Recording and Playback
for Professional Environments
The SS-CDR250N is a networkable solid-state/CD 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 or in MP3 and audio CD formats to CD via a slot-loading drive.
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.
Ethernet connection for remote control and file transfer by FTP
By connecting the recorder to an Ethernet network, you can make use of the built-in FTP functions to upload recorded files to a specified server or download files for playback. Since the unit also acts as an FTP server, files on the unit can also be accessed from a computer.
With SNTP support, the SS-CDR250N can automatically update its internal clock at regular intervals over a network, so that timer events can be executed accurately.
Event list for time-based automation
Event lists can be used to auto-play audio files for background music and announcements – useful in retail stores or restaurants. Apart from playback, they can also schedule recording, downloading and other events.
By combining playback events with download events, audio files can be automatically retrieved from a server for playback. This can also be used for centralised file distribution from a corporate headquarter to multiple locations – perfect for playing files simultaneously in chain stores, for example.
Dedicated control app
With SS250 Control, Tascam offers a freely available dedicated control app that enables you to remotely control the recorder’s transport functions, access menu settings and monitor levels in realtime from your Android or iOS tablet or smartphone. You can also use the app to lock the buttons on the unit’s front to prevent operation from the unit itself when it is located in a public place, for instance. And the app shows icons to inform you when files are being uploaded or downloaded by FTP.
Applications for Windows and macOS computers are also available for free download from the Tascam website.
Backup and relay recording using two SD cards and a USB medium
When using the BACKUP option while recording, the unit stores audio files on both selected media in parallel. You can select from the menu which of the remaining media is used for the backup.
When using the RELAY option while recording, the unit uses multiple media in succession to allow continuous recording for long periods of time.
To further help you secure your valuable recordings, the unit automatically saves and closes recording files every few seconds to safeguard against data loss in case of a power outage.
XLR, RCA, AES/EBU, SPDIF – what else would you need?
The SS-CDR250N offers a variety of audio inputs and outputs to integrate into virtually any environment. You can choose from analogue XLR or RCA inputs and outputs or use AES/EBU (XLR) or SPDIF (Coaxial) to connect to digital equipment. You can also enable 48-volt phantom power in the menu to use the XLR inputs with condenser microphones.
Q-SYS Control (integration under development)
Currently under development, this plugin will integrate the SS-CDR250N with the Q-SYS Platform using the optional Tascam IF-E100 Ethernet card. This will allow full playback control to be accessed directly from the Q-SYS user control interface.
Transport functions, source selection and file navigation can be accessed through Q-SYS without touching the hardware, thus streamlining operations in commercial AV environments such as conference centres, hospitality spaces and houses of worship. The official Tascam plugin will be available via the Q-SYS Designer software.
