  • The TASCAM HS-20 is a professional solid-state audio recorder and player, built for the needs of network-connected installations. Reliable recording and playback can be controlled, accessed, and scheduled from an internet connection, allowing remote access without visiting the site. 

    Recording and playback can be scheduled for automatic operation. A built-in FTP client and server are included in the HS-20, for either automated or manual file transfer and management. Record meetings, classes, or worship services on a regular schedule, then automatically upload the recording to a server and delete the recording, all without supervision. Or upload a new playlist for in-store music playback, including promotional announcements, all from a central location. 

    The HS-20 records to either SD Card or Compact Flash media, at up to 192kHz/24-bit Broadcast WAV formats. Balanced and unbalanced connections are available on the rear panel, as well as RS-232C Serial and Parallel connections for wired remote control. It's built on TASCAM's more reliable recording platform, designed for broadcast use.

    For automated recording or playback with network accessibility and control, TASCAM's HS-20 is the only choice.

    FTP client for uploading and downloading files to/from servers
    The included FTP client function allows the user to move files using a network computer, or from the HS-20 unit itself.

    Automatic uploading function
    After recording, the HS-20 can automatically upload recorded files to a designated server. This allows simple archive creation for recorded data. This is important for archiving regularly scheduled events like classes, lectures, worship services, and performances. Since uploading occurs in the background, recording and playback operations are not interrupted.

    SNTP client function enables accurate time setting
    The SNTP client functions of the HS-20 enable automatic synchronization of the date and time with an NTP server over the Internet. Automatic time synchronization can be set to occur whenever the unit is started, and every (24) hours.

    Event lists with time-based management
    Event lists enable the automatic playback of files such as background music and announcements - useful in retail stores and restaurants. Utilize the event lists for scheduled recording, playback, downloading and other events. By combining playback events with download events, audio files can be automatically retrieved from a server for playback. The HS-20 FTP server functions also enable centralized file management from a corporate headquarters to multiple locations - perfect for playing files simultaneously in a chain of retail stores.

    SD/SDHC and Compact Flash Recording Media
    In addition to Compact Flash cards (widely used in the broadcast industry), the HS-20 also supports SD and SDHC cards. The HS-20 was designed for solid-state recording - with no moving parts and immunity to vibration. This design ensures broadcast-level reliability and durability in any environment.

    Touchscreen TFT color display allows intuitive operation
    The HS-20 features a touchscreen color display. The graphical user interface is intuitive and easy to understand. Menus for inputs, outputs, and other settings are simple and on one screen. All parameters can be accessed by touching the screen and changing the settings. Compared to earlier displays that could only show small bits of information, this interface is complete and easy to use.

    Network Access via 1000BASE-T (Gigabit) Ethernet
    The HS-20 supports 1000BASE-T Gigabit LAN and uses FTP as its work protocol. It can be accessed from any system, including Windows, Macintosh and UNIX. Inclusion of FTP functions allows file transfers between CF/SD cards and servers. This enables various applications, including loading of files onto a transfer system. In addition, this also provides an environment for remote control over a network. These features contribute to making systems and workflows more efficient.

    VNC (Virtual Network Computing) is also supported, allowing a VNC viewer application to operate the system from a computer by viewing the screen shown on this unit's LCD.

    TASCAM Broadcast-Quality Operation and Reliability
    The HS-20 utilizes a real-time operating system for fast start-up time and system operation. Files are automatically saved during recording about every (25) seconds to prevent loss of data due to unexpected power interruptions. Even removal of a memory card during operation will not stop the system.
