wordclock master” on page 10. You can select
the sampling frequency using mLAN Auto Con-
nector or mLAN Graphic Patchbay (page 20).
INT: The i88X uses the internal clock at
44.1 kHz.
ADAT: The i88X uses the incoming ADAT sig-
nal as the master clock.
mLAN: The i88X uses the incoming mLAN
signal as the master clock.
Lit green: The i88X locks to the word-
clock master.
Flashing green: The i88X is not locking to the
wordclock master.
C[mLAN ACTIVE] indicator
This indicator lights up when the i88X is operat-
ing.
The indicator turns off when an error occurs
during an mLAN operation.
When you click the [ID] button in mLAN Auto
Connector or mLAN Graphic Patchbay
(page 20) to identify the corresponding mLAN
device in the network, the indicator flashes.
The indicator also lights up if an mLAN
cable is not connected to the unit.
D[STANDBY/ON] switch
This switch turns the power to the unit on
or off (Standby).
Be sure to follow the procedures described in
“Turning the Power to the i88X and Connected
Devices On and Off” on page 12 when you
turn the power to the i88X on or off.
Even when the switch is in the STANDBY posi-
tion, a small amount of electricity is still flowing
to the unit. When you do not plan to use the
i88X for an extended period of time, be sure to
unplug the AC power adapter from the AC out-
let.
■About the OPTICAL SELECT Switch, MASTER CLOCK Indicators, and Wordclock
The function of the OPTICAL IN and OUT jacks (J) specified by the [OPTICAL SELECT] switch (7), and
which MASTER CLOCK indicator (B) will light up, varies depending on which mLAN device in the mLAN
network is being used as the wordclock master.
1. When the wordclock master in an mLAN
network is an mLAN device other than
the computer and i88X (that is, when the
i88X is using the incoming mLAN signal
as the master clock):
MASTER CLOCK indicators
The [mLAN] indicator lights up.
[OPTICAL SELECT] switch
DIGITAL:
The OPTICAL IN and OUT jacks function as a
digital stereo input and output.
ADAT NORMAL or ADAT DOUBLE:
The sampling frequency in the mLAN network
determines the operating mode (NORMAL or
DOUBLE). You can select either mode when
the OPTICAL IN and OUT jacks are used as the
ADAT input and output.
2. When the i88X is referencing the incom-
ing ADAT master clock signal and the
i88X has been specified as the clock mas-
ter in the mLAN network (that is, when
the i88X is using the signal from ADAT as
the master clock):
MASTER CLOCK indicators
The [ADAT] indicator lights up.
[OPTICAL SELECT] switch
DIGITAL:
The OPTICAL IN and OUT jacks function as a
digital stereo input and output, but the IN jack
is unable to receive the ADAT wordclock sig-
nal. Therefore, the i88X automatically switches
to its internal clock running at 44.1 kHz. (Refer
to Case 3.)
ADAT NORMAL:
The OPTICAL IN and OUT jacks function in
ADAT NORMAL mode.
ADAT DOUBLE:
The OPTICAL IN and OUT jacks function in
ADAT DOUBLE mode.
3. When the i88X is not receiving the cor-
rect wordclock:
MASTER CLOCK indicators
The [INT] indicator lights up, and the i88X ref-
erences its internal clock running at 44.1 kHz.
In Case 1, the [mLAN] indicator also lights up.
In Case 2, the [ADAT] indicator also lights up.
[OPTICAL SELECT] switch
DIGITAL:
The OPTICAL IN jack functions as the digital
stereo input. In this case, you can still monitor
analog inputs (from INPUTs 1-8) and digital
stereo input (from OPTICAL IN). Therefore,
you can monitor the sound from a musical
instrument or microphone connected to the
i88X without running the computer.
ADAT NORMAL or ADAT DOUBLE:
ADAT signals are unavailable, although you
can still monitor analog input (from INPUTs 1-
8).
