Fundamentals of mLAN
mLAN is a digital network for music that was developed based on IEEE1394, an industry-standard
high-performance data communications protocol.
Digital music environments that do not feature mLAN require dozens of cables for various devices
and purposes, including MIDI cables and audio cables to route MIDI and audio signals. If you wish
to make changes to such systems, you must physically disconnect and re-connect these cables.
For example, adding another synthesizer to a system requires two MIDI cables and two or more
cables for audio (for stereo equipment). Making the appropriate connections may require special
knowledge of inputs, outputs, stereo settings, and perhaps connector impedance.
The larger the system, the more complicated and expensive these connections become, increasing
the likelihood of errors and difficulties. It takes time and effort to investigate such errors and their
underlying causes. You may have already experienced the unpleasantness of tracking various cables
through a spider’s web of connections.
English
mLAN simplifies cable connections by using only one type of IEEE1394 cable, thus enabling you to
configure extremely sophisticated systems. There is no need to re-patch cables to change routings
of MIDI and audio signals between mLAN devices.

■ 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 incoming ADAT master clock signal and the
i88X has been specified as the clock master 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 signal. 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 correct wordclock:
MASTER CLOCK indicators
The [INT] indicator lights up, and the i88X references 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).

These TRS phone type 1/4" output jacks (balanced) output an audio analog signal, which is
the combination of mLAN input channels 1 & 2,
and audio monitoring output selected via the
[SELECT] (7) switch on the front panel. The
nominal output level is +4 dBu (pages 16 and
17).
H OUTPUT 3-8 (TRS phone) jacks
These TRS phone type 1/4" output jacks (balanced) output audio analog signals from mLAN
input channels 3-8 respectively. The nominal
output level is +4 dBu.
I DIGITAL STEREO COAXIAL IN & OUT
jacks
These coaxial jacks (RCA pin connectors) input
and output IEC-60958 consumer format digital
audio signals. Connect these jacks to the stereo
input and output of a DAT recorder, MD
recorder, etc., using RCA pin cables for digital
audio.
J OPTICAL IN & OUT jacks
These optical jacks input and output digital stereo or ADAT audio signals. Use the [OPTICAL
SELECT] (A) switch on the front panel to select
DIGITAL STEREO, ADAT NORMAL, or ADAT
DOUBLE mode.
NOTE
The coaxial and optical digital stereo
input jacks feature a built-in sampling
rate converter (SRC), which enables
audio signals at different sampling frequencies to be input from connected
devices.
K MIDI IN & OUT ports
Connect MIDI equipment here. These ports
enable you to transmit MIDI messages between
a computer or mLAN devices in an mLAN network and a MIDI instrument connected to the
i88X.
L DC IN terminal
Connect the included AC adapter (PA-5D) here.
WARNING
Be sure to use the included adapter. Using an
AC adapter other than the PA-5D may cause
damage to the i88X, and may even pose a serious electrical shock hazard. Connect the
adapter to an AC outlet of the specified voltage.
M mLAN 1 & 2 connectors
These 6-pin IEEE1394 connectors enable you to
connect the i88X to an mLAN device or
IEEE1394-compatible (FireWire/i.Link) device.
The operation is identical regardless of which
connector is used (mLAN 1 or mLAN 2). If the
target device has a 4-pin connector, use a commercially available 4-pin to 6-pin IEEE1394
cable. Avoid creating a connection loop
(page 23) when connecting the devices.
NOTE
Yamaha recommends that you use an
IEEE1394 cable with a length of 4.5
meters or less.
