Level meter for easy setting of a reference
level
The level meter with a reference marker
function provides two types of signal level
indications for precise setting of
recording and playback levels.
Two pairs of composite digital (video)
signal inputs
The unit is equipped with two pairs of
composite digital (video) signal inputs, to
make it possible to select alternately
composite digital (video) playback signals
from two recorders.
Status connector
The status connector, which outputs error
data of PCM recorded tapes, makes it
possible to analyze tape errors when
connected to a DTA-2000 digital tape
analyzer.
Small power consumption
Newly developed LSis incorporated in the
logic circuitry reduce power consumption,
which enables adoption of a linear power
supply in the unit.
Optional printed circuit boards
Optional printed circuit boards make it
possible to extend functions of the unit.
• RAR (Read After Read! function
When the unit with an optional RAR board
(DABK-1630) installed is used with a
digital audio recorder which has a
read-after-read function (such as a Sony
DMR-4000 digital master recorder), the
playback has very high reliability. In
addition, with the RAR board installed, a
read-after-write function for dubbing and
editing can be used with this unit.
• Digital I/0 interface
When optional digital I/O boards
(DABK-1631) are installed, the analog
input/output connectors provide digital
input/output data which conforms to the
AES/EBU standards.
