Precautions
• Do not place a container with liquid or small metal
objects on top of this unit. Liquid or metal objects
inside this unit are a fire and electrical shock hazard.
• Do not allow water to enter this unit or allow the unit
to become wet. Fire or electrical shock may result.
• Connect this unit’s power cord only to an AC outlet of
the type stated in this Owner’s Manual or as marked
on the unit. Failure to do so is a fire and electrical
shock hazard.
• 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 car-
pet.
• 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.
• Should this unit/AC adapter/power supply be
dropped or the cabinet be damaged, turn the power
switch off, remove the power plug from the AC outlet,
and contact your dealer. If you continue using the unit
without heeding this instruction, fire or electrical
shock may result.
• If the power cord is damaged (i.e., cut or a bare wire is
exposed), ask your dealer for a replacement. Using the
unit with a damaged power cord is a fire and electrical
shock hazard.
• Do not remove the unit’s cover. You could receive an
electrical shock. If you think internal inspection,
maintenance, or repair is necessary, contact your
dealer.
• Do not modify the unit. Doing so is a fire and electri-
cal shock hazard.
• When rack-mounting the unit, allow enough free
space around the unit for normal ventilation. This
should be: 10 cm at the sides, 15 cm behind, and 30
cm above.
• For normal ventilation during use, remove the rear of
the rack or open a ventilation hole.
• If the airflow is not adequate, the unit will heat up
inside and may cause a fire.
• This unit has ventilation holes at the top, bottom, and
rear to prevent the internal temperature rising too
high. Do not block them. Blocked ventilation holes
are a fire hazard.
• Hold the power cord plug when disconnecting it from
an AC outlet. Never pull the cord. A damaged power
cord is a potential fire and electrical shock hazard.
• Do not touch the power plug with wet hands. Doing
so is a potential electrical shock hazard.
• The digital circuits of this unit may induce a slight
noise into nearby radios and TVs. If noise occurs,
relocate the affected equipment.
• XLR-type connectors are wired as follows: pin 1:
ground, pin 2: hot (+), and pin 3: cold (–).
Rack Mounting Caution
If the unit is rack mounted and transported regularly,
for example, when on a tour, we recommend that the
rear of the unit be supported by fitting a pair metal
brackets, one each side. The following drawing pro-
vides the information necessary to make such brack-
ets.
Note that only one bracket is shown here and the
bracket for the other side must be bent in the opposite
direction.

Thank you for choosing the AI8 analog input box, or the AI8-ML8/AI8-AD8/AI8-ML4AD4 analog input
unit, specifically designed for the Yamaha PM1D digital audio mixing system.
The AI8 inputs signals to the DSP unit DSP1D/DSP1D-EX engine (controlled via the CS1D control sur-
face). Up to ten AI8s can be connected to each DSP1D/DSP1D-EX.
Be sure to ask an authorized Yamaha service engineer to install the card and set up the unit.
Never perform installation and setup by yourself.

INPUT UNIT ID indicator
This indicator displays the ID number of the INPUT
connector of the DSP unit DSP1D/DSP1D-EX con-
nected to the AI8. If an error occurs in the connection
to the DSP1D, or if the unit does not lock to the word-
clock signal, one of the following error indications
appears.
Error message
E1
: The AI8 is connected to the OUTPUT connector
of the DSP1D/DSP1D-EX. Connect the AI8 to the
INPUT connector.
E3
: A cable is disconnected from the OUTPUT A, B,
or C connector on the rear panel, or the connec-
tion is made incorrectly. If the connection is
proper, replace the cable.
UL
: The unit does not lock to the wordclock signal.
UC
: The control signal is not being received correctly.
“

”:(two dots and the ID number of the OUTPUT
connector on the DSP1D/DSP1D-EX)
Illuminating or flashing dots mean that the AI8 is
connected in Mirror mode from the DSP1D/
DSP1D-EX.
If “

” lights up continuously during Mirror
mode operation, the CONTROL PORT switch
(
4
) setting matches the setting controlled from
the CS1D and the system is operating normally.
If the control signal from the CS1D has changed
the setting during Mirror mode operation and it
does not match the CONTROL INPUT PORT
switch (
4
) setting any more, this indicator
changes in the following order.
“” means that the control signal from the
CS1D has changed the setting to “A.”
“” means that the control signal from the
CS1D has changed the setting to “B.”
During this time period, you can connect or dis-
connect the cable from the unselected output
connector.
If you set the CONTROL PORT switch so that it
matches the setting made via the control signal
from the CS1D, “

” lights up continuously.
B
PHANTOM MASTER switch, indicator
This switch is used to turn the phantom power on and
off to all the headphone amplifiers of the input con-
nectors (for which the phantom power is switched on)
on the AI8 that has the LMY2-ML analog input card
equipped with the headphone amplifier. When you
turn on the switch, the indicator on the left of the
switch lights up.
C
POWER ON/OFF
Use this switch to turn the power to the AI8 on and
off. When the power is turned on, the INPUT UNIT
ID indicator lights up.
D
CONTROL PORT switch
This switch enables you to select a port used to con-
trol the AI8 via the DSP unit DSP1D/DSP1D-EX.
Select from OUTPUT A, B, and C to receive the con-
trol signal for switching between channels A and B on
the LMY2-ML analog input card, or turning the
phantom power on and off.
During Mirror mode operation, the control signal
sent from the CS1D has priority, and the CONTROL
PORT switch is disabled. In this case, the INPUT
UNIT ID indicator shows the status. For more infor-
mation, refer to
1
INPUT UNIT ID indicator.
E
OUTPUT connectors A, B, C
These connectors are used to output multi-channel
digital audio signals. The same signal is routed to all
three connectors. Be sure to use the included genuine
Yamaha half-pitch 68-pin cable for connection.
Optional genuine Yamaha cables in a variety of
lengths are also available.
F
WORD CLOCK IN jack, ON/OFF switch
The WORD CLOCK IN jack is used to provide the
word clock to the AI8 from a connected external
device or a clock generator. Use a BNC cable with an
impedance of 75
Ω
for connection.
The WORD CLOCK ON/OFF switch is used to termi-
nate the word clock connection. Basically, if the AI8 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.
G
WORD CLOCK OUT jack
The WORD CLOCK OUT jack is used to provide
word clock from the AI8 to the connected external
device, such as a clock generator, digital MTR, and
DAT recorder. Use a BNC cable with an impedance of
75
Ω
for connection.
