Tascam SS-CDR250 is Professional Audio’s “Editor’s Choice 2018”

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. Time synchronisation via SNTP is also possible.

With its dual SD card slots, the SS-CDR250N 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-CDR250N 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-CDR250N 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.


Backup and relay recording using two SD cards and a USB medium


When recording, the SS-CDR250N can use two SD cards and a USB flash drive to create backups or use multiple media in succession. A folder with the same file path as the current media will be created on the secondary media and used for backup and relay recording.

Backup recording can prevent you from unpleasant surprise

When using the BACKUP option while recording, the unit stores audio files on both selected media in parallel. Such backups can help you avoid trouble in case of problems with a recording medium. You can select from the menu which of the remaining media is used for the backup.

Relay function for long recording times

When using the RELAY option while recording, the unit uses multiple media in succession to allow continuous recording for long periods of time. You can even combine a dual-format recording (record in WAV and MP3 format simultaneously) with the relay function.

Automatic file closing

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.


SS-CDR250NXLR, 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.

SS-CDR250NIf you have a Dante network …

By installing a Tascam IF-DA2 Dante network card (available as an option), the SS-CDR250N/SS-R250N can easily be integrated into your Dante network. This card fits to an extension slot on the rear side and offers two channels of audio in both directions (in and out) at up to 96 kHz / 24 bits.

SS-CDR250NEthernet connection for remote control by Telnet and file transfer by FTP

By connecting the recorder to an Ethernet network, you can remotely control it by Telnet. Access is possible from any kind of system, including Windows, Mac and Unix. A network connection is also required to 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.

SNTP time synchronization

With SNTP support, the SS-CDR250N/SS-R250N can automatically update its internal clock at regular intervals over a network, so that timer events can be executed accurately.

SS-CDR250NExternal parallel/serial control

In addition to remote control and monitoring using the LAN function, external remote control using parallel and RS-232C serial protocol is supported. This allows the unit to be integrated into media systems and other environments.

SS-CDR250NRC-SS150 Dedicated wired remote control

The dedicated RC-SS150 remote control unit is also connected and power-supplied via the unit's RS-232C port. It has 12 flash start buttons arranged around a clearly readable TFT display and gives you access to playlists with up to 96 tracks. You can also change playback area and playback mode or settings like Repeat, Auto Cue, Auto Ready and Incremental playback.

Tascam SS250 ControlDedicated control app for Android and iOS

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.
