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.
