VR320 Digital Communications Logger

VR320 Digital Communications Logger

      The Eventide VR320 Digital-Audio Logger allows users to replace mountains of expensive, unwieldy reel-to-reel tapes with tiny, economical DAT tapes. It is ideally suited for full-time audio logging of public safety communications, 911 Emergency phone lines, air traffic control, calls to financial services firms, broadcast programming and other uses.

   It uses the latest DAT drive standard, DDS-2, to provide storage of 500+ hours on 120 meter data grade DAT tapes, divided among up to 32 channels. Shorter tapes of 90 meters can also be used, and more storage using DDS 3 is available optionally, as is optical drive capability. On playback, the VR320 searches by date, time and channel to locate any audio segment in under two minutes.

   The Eventide VR320 is available in one or two drive models. The two drive model provides maximum flexibility by recording on one drive while simultaneously playing back on the second. Or, the unit can be set to record two identical tapes simultaneously, creating a "start/stop" work tape and an uninterrupted archive tape. The second drive can also be automatically switched to start recording when the first tape is full, thus doubling unattended logging time to over 1000 hours.

   The VR320 is equipped with an internal hard disk memory module with a capacity of approximately 120 channel-hours (longer storage capacities are optionally available). the memory module can continue to record even if the tape is playing back an earlier segment. Upon resumption of tape recording, the memory module transfers to the tape the audio that was not recorded in real-time, thus maintaining the completeness of the taped log. For additional protection, the VR320 protects its data with a built-in Uninterruptible Power Supply, which allows the unit to continue recording through brief outages. This also provides a "data-safe" power down sequence should the power outage continue.

   The VR320 Digital-Audio Logger can be ordered with up to 32 input channels in groups of 8. Upgrades to additional channels from the 8 or 16 channel versions are as simple as plugging in optional I/O boards. The user can specify any combination of standard audio input I/O boards and boards that are optimized for interfacing with telephone systems.

   As an option, the VR320 can now be ordered with Exabyte 8mm drives in lieu of the standard DAT drives. These drives are capable of recording about 1000 channel hours on each tape, almost twice the capacity of 120 meter DAT tapes. Another option for added convenience is an inexpensive printer which the VR320 uses to automatically print its own tape labels, including beginning and end date and time.

   Eventide also offers a line of compact, economical 4-channel DAT-based recorder/players and playback-only decks which offer two-way compatibility with the Eventide VR320 and Dictaphone 9800 series 24-channel loggers. Any of the 24 channels on tapes recorded in these machines can be searched and played back on the Eventide 4-channel units - up to four channels can be played simultaneously. Tapes recorded on the 4-channel recorder can also be played back on the 24-channel Eventide VR240 and Dictaphone 9800 units as well. As well as our 4-channel VR204 recorder/player and VP204 playback deck, as well as the two piece desktop model VP244 playback unit.

   Eventide is a pioneer in the development of digital communications loggers. The proven technology and advanced features of the VR240 series make it the ideal choice for preserving important communications.
