A 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.

If " x " 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.

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 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 for connection.
