DAE-1100/llOOA digital audio editor
This unit is used with a PCM-1630 digital
audio processor and a BVU-BOODB or
DMR-2000/4000 recorder, to provide fully
automatic digital-to-digital,
high-precision audio editing.
The unit
also features a search dial for quick
access to an edit point, an edit rehearsal
function and a review function.
DTA-2000 digital tape analyzer
This unit is designed to output error data
of PCM recorded tapes to a printer
according to the status signals from a
PCM-1630 digital audio processor.
1-4. PRECAUTIONS
1-4-1. On Power Supply
The unit is designed to operate on 100,
120, 220 or 240 V ac.
Before connecting
the unit to the power source, check to see
that the unit's operating voltage is
identical with the local power line
voltage.
The voltage selector is located
on the rear panel.
If the voltage selector
must be reset, proceed as follows.
Remove the voltage selector cover with a
screwdriver, pull out the selector and
re-insert it so that the correct voltage
figure appears on the cutout of the
selector.

l-4-2. On Ventilation
Good air circulation is essential to
prevent internal heat build-up in the unit.
Place the unit in a location with adequate
air circulation.
The ventilation holes
must be unobstructed to operate the unit
properly and to prolong the life of its
components.

1-4-3. On Operating Temperature Range
Do not install the unit in a location near
heat sources such as radiators or air
ducts, or in a place subject to direct
sunlight.
The temperature range for
correct operation of the unit is as
follows.
Operating temperature:
o
0
c
to 40°C (32°F
to 104 °F)
Temperature for which performance of the
unit is assured: 5°C to 35°C (41°F to
95 °F)
1-4-4. On Warm-up Time of the Unit
After turning the power on, wait for more
than 30 minutes to warm up the unit before
operating it.
1-4-5. On Analog Inputs and Outputs
When the ANALOG INPUT and OUTPUT connectors
of the unit are to be used in an unbalanced
connection, be sure to connect the "cold"
pin with the "ground" pin.
If the "hot"
pin is connected with the "ground" pin, a
de electric potential may arise and affect
the characteristics.
l-4-6. On Composite Digital (Video) Inputs
and Outputs
The unit is equipped with two types of
composite digital inputs and outputs: BNC
type connectors (COMPOSITE DIGITAL INPUT
and OUTPUT) and S-pin multi-connectors
(COMPOSITE DIGITAL) •
For inputs, the
COMPOSITE DIGITAL INPUT A connector and the
COMPOSITE DIGITAL A connector are connected
in parallel inside the unit, and the
COMPOSITE DIGITAL INPUT B connector and the
COMPOSITE DIGITAL B connector are connected
in parallel.
Be sure to use only one type
of connector at a time.
If
both types of
connectors are used at the same time and
signals are input to these connectors
simultaneously, the signals will interfere
with each other.
(The COMPOSITE DIGITAL
INPUT A connector and the COMPOSITE DIGITAL
B connector, or the COMPOSITE DIGITAL. INPUT
B connector and the COMPOSITE DIGITAL A
connector can be used simultaneously.)
For
outputs, simultaneous use of a pair of BNC
connectors and a pair of S-pin
multi-connectors is possible.
l-4-7. On Short-circuit Protection
The circuit power supply section
incorporates a short-circuit protection
system which cuts off the output voltage
when the power supply section is
short-circuited.
When the short-circuit
protection activates, turn off the power
immediately.
Wait for more than 30
seconds, then turn the unit on.
The output
voltage will be restored to normal.
