q [ ]/[ ] (power switch)
Turns the unit’s power (supplied from the AC IN
connector) on [ ]/off [ ]. If power is supplied from
the AC IN connector and this power switch is also on,
the front panel POWER INT indicator is lit.
CAUTION
Even when the power switch is turned off, a small amount of
current is flowing through the unit. When you are not using
the product for a long time, make sure to unplug the power
cord from the AC outlet.
NOTE
Rapidly turning the unit on and off in succession can cause
it to malfunction. After turning the unit off, wait for at least 6
seconds before turning it on again.
w AC IN connector
Connect the supplied AC power cord here. First
connect the AC power cord to the RSio unit, then insert
the power cord plug into an AC power outlet.
The supplied AC power cord features a V-lock
mechanism via a latch, which prevents the power cord
from coming off accidentally.
Insert the cable plug all the way until it locks in securely.
CAUTION
Be sure to turn the power off before connecting or
disconnecting the power cord.
Press the latch button on the plug to disconnect the
power cord.
e EXT DC INPUT connector
This is an XLR-4-32 type connector through which an
external power supply (+24V) can be provided as a
backup for the internal power supply of the RSio64-D.
CAUTION
Before connecting the external power supply, you must turn
off the power of this unit and the power of the external power
supply. Malfunctions or electrical shock may occur if you fail
to observe this caution.
NOTE
• This power supply cannot be turned on/off by the power
switch.
• If an external power supply is connected, the RSio64-D will
operate normally when the internal and external power
supplies are both on, as well as when only one of them is on.
• If both power supplies are on and one of the power supplies
fails during operation, the unit automatically switches to the
other power supply. The state of the power supply is shown
by the front panel POWER indicator.
r Grounding screw
Since the included power cord has a three-conductor
plug, this unit is appropriately grounded if the AC
outlet is grounded. In some cases, you may be able to
reduce hum and interference by connecting ground to
this screw as well.
t SLOT 1–4
Mini-YGDAI I/O cards can be installed in these slots.
Each of the four slots is equipped with an SRC.
y SLOT ACTIVE indicator
Indicates whether the slots are powered.
CAUTION
Do not insert or remove a Mini-YGDAI card if this indicator is
lit. Malfunctions or electrical shock may occur if you fail to
observe this caution.
