shock hazard.

•Be sure to connect to an appropriate outlet with a pro­tective grounding connection. Improper grounding
can result in electrical shock.

•Do not scratch, bend, twist, pull, or heat the power
cord. A damaged power cord is a fire and electrical
shock hazard.

•Do not place heavy objects, including this unit, on top
of the power cord. A damaged power cord is a fire and
electrical shock hazard. In particular, be careful not to
place heavy objects on a power cord covered by a car­pet.

•If you notice any abnormality, such as smoke, odor, or
noise, or if a foreign object or liquid gets inside the
unit, turn it off immediately. Remove the power cord
from the AC outlet. Consult your dealer for repair.
Using the unit in this condition is a fire and electrical
shock hazard.

I/O UNIT ID indicator

This indicates the connector number (the number of
the connector used to control the DIO8) of the engine
DSP unit (DSP1D/DSP1D-EX) connected to the DIO8.
If more than one connector is connected, either A or B
will be automatically selected as the connector for
control, according to the connection status of the
INPUT and OUTPUT jacks.
If there is a problem such as an incorrectly connected
DSP unit or if the word clock is not locked, this will be
indicated by one of the following error displays.

Error displays

E1

: The OUTPUT connector of the DIO8 is connected

to the OUTPUT connector of the DSP unit. Please
connect it to the INPUT connector.

E2

: The INPUT connector of the DIO8 is connected to

the INPUT connector of the DSP unit. Please con­nect it to the OUTPUT connector. (This will not be
displayed if the OUTPUT connector of the DIO8 is
connected.)

E3

: Either the cable connected to the INPUT or OUT-

PUT connector has become disconnected, or the
connection destination is incorrect. If the connec­tion is correct, try replacing the cable. (This will be
displayed only if both INPUT and OUTPUT are
abnormal.)

UC

: Control signals are not being received correctly.

Make sure that the power of the DSP unit is on.

These error displays indicate an error for the INPUT/
OUTPUT A connectors if the PORT B SELECTOR
switch is set to 5-8, and indicate an error for the
INPUT/OUTPUT B connectors if the PORT B SELEC­TOR switch is set to 1-4. Even if there is an incorrectly
connected connector, the error display will not appear
if there is another control connector that is usable.

UL

: The word clock is not locked. Make sure that the

word clock source is selected correctly, and that
the cable is connected correctly.

Note:

You can change the PORT B SELECTOR setting by
sending the control signal from the CS1D. At this
time, two dots (“. .”) light up besides the indicator
message described above.
If the PORT B SELECTOR switch setting on the
unit is different from the actual operation, one of
the following messages and the indicator message
described above will appear alternately.

• If the PORT B SELECTOR switches to slots 1-4:
“”

• If the PORT B SELECTOR switches to slots 5-8:

B

PORT B SELECTOR switch

Use this switch to select slots 1-4 or slots 5-8 to assign
the INPUT A/OUTPUT A connectors (referred to as
PORT A) and the INPUT B/OUTPUT B connectors
(referred to as PORT B).

If the PORT B SELECTOR is set to 5-8, slots 1-4 are

assigned to PORT A and slots 5-8 are assigned to
PORT B for input and output signals.

If the PORT B SELECTOR is set to 1-4, only PORT B

is available for input and output signals via slots 1-4.
In reality, slot 1-4 input signals are routed to OUT­PUT A, and the INPUT B signal is output to slots 5-8.
If you wish to route slot 1-4 signals to both OUTPUT
A and B, use this setting.

C

POWER ON/OFF switch

Use this switch to turn the power to the DIO8 on and
off. When the power is turned on, the I/O UNIT ID
indicator lights up.

D

WORD CLOCK IN jack, ON/OFF switch

The WORD CLOCK IN jack is used to provide word
clock to the DIO8 from a clock generator or a con­nected external device. Use a BNC cable with an
impedance of 75

Ω

for connection.
The WORD CLOCK ON/OFF switch is used to termi­nate the word clock connection. Basically, if the DIO8
is the last device of the word clock chain, or if nothing
is connected to the WORD CLOCK IN/OUT jacks, set
this switch to ON.

E

WORD CLOCK OUT jacks

The WORD CLOCK OUT jacks are used to provide
word clock from the DIO8 to the connected external
device, such as digital MTR or DAT recorder. Use a
BNC cable with an impedance of 75

Ω

for connection.

Caution:

If you are using the MY8-AT card to handle ADAT
format signals, synchronization may tend to be
lost easily depending on the device that is con­nected. For the most reliable synchronization, we
recommend that the word clock for digital audio
devices being used together be taken from a con­nector other than the ADAT-format connector,
such as this connector.
