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).

Wordclocks

NOTE

NOTE

In a system that features multiple digitally-connected devices, all digital devices must be synchro­nized when digital audio signals are transferred from one device to another.

Even if the devices use matching sampling frequencies, if their audio processing timing is not
synchronized, they might not receive signals correctly, and audible noise, glitches or clicks may
occur. Synchronization is achieved using a wordclock (a clock signal that synchronizes all digital
audio signals in a system).

In a typical digital audio system, one device operates as the wordclock “master” and transmits a

English

wordclock signal. The other devices operate as wordclock “slaves,” synchronizing to the word­clock master.

To connect the i88X to external devices via mLAN, in mLAN Auto Connector or mLAN Graphic
Patchbay, select a device to be the master, then set the other devices as slaves. The i88X can
operate at a sampling frequency of 44.1 kHz, 48 kHz, 88.2 kHz or 96 kHz as either the wordclock
master or slave.

Using the i88X as the wordclock master in an mLAN network
(Using an ADAT-compatible device as the wordclock master in an mLAN network)

1. On the ADAT-compatible device connected to the i88X, specify the ADAT-compatible
device as the wordclock master.

2. Set the [OPTICAL SELECT] switch on the front panel to ADAT DOUBLE or ADAT NORMAL
(page 10).

3. In mLAN Auto Connector or mLAN Graphic Patchbay, assign the i88X as the wordclock
master in the mLAN network.

Using the i88X as the wordclock slave in an mLAN network

In mLAN Auto Connector or mLAN Graphic Patchbay, assign an mLAN device other than the
computer or i88X as the wordclock master.

Use an ADAT-compatible device or digital device (if it is connected to the i88X) to assign
the device as a wordclock slave.

For information on setting the sampling frequency and wordclock, refer to the Installation Guide,
or to the mLAN Graphic Patchbay Online Manual, or the owner’s manual for your ADAT-compat­ible device.

For information on system requirements and settings for making mLAN connections, refer to
the separate Installation Guide and mLAN Graphic Patchbay Online Manual.

Saving mLAN connection settings to the corresponding mLAN device

When you make mLAN connections on the computer, the connection settings will be automati­cally saved in the corresponding mLAN devices. Therefore, if you used mLAN Graphic Patchbay
to configure a network that excludes a computer, the next time you use the network, you will be
able to activate the network just by turning on the power to the network’s mLAN devices (with­out starting the computer).

About connections with external devices when using the i88X with a computer

When using audio devices, musical instruments and computers at the same time, there is bound to
be some noise in the system, the amount of which depends on the connections. Knowing how to
minimize noise is extremely important when designing and setting up a studio.

As advanced as the i88X is, it too is susceptible to noise. Various types of noise may be generated
and recorded to your audio sequencer, depending on the power sources/grounding scheme and
how the various devices are connected.

There is no ideal way to completely eliminate such noise. However, one can decrease noise by iso­lating the cause and applying a suitable remedy. Below are a couple of examples that may apply.

• High-pitched buzzing or whirring operation noise in the computer

This is caused by operation noise of the computer leaking to other devices through the mLAN
cable or audio cable, and may be caused by improper grounding of the power source.

• Low humming noise

Noise of this type is generally due to improper grounding of the power source.

English

NOTE

The noise may differ depending on the circumstances (specifications of each device and loca­tions of use).

If problems like these happen, try the following measures to minimize the noise.

NOTE

If the noise disappears when turning down the volume of the i88X and/or if the noise persists
even when disconnecting the mLAN cable or turning off the computer, other reasons for the
noise are likely. Refer to the Troubleshooting section in the Owner’s Manual.

1. Use balanced cable connections when connecting analog audio.

By using proper balanced connections, you can minimize the noise.

NOTE

This may have no effect depending on the specifications of the connected device.

NOTE

Microphones and Adjusting the Input Level

Signals input at INPUT 1-8 jacks are routed to mLAN output channels 1-8 respectively. If you have
selected any pair from channels 1/2 through 7/8 for monitor output, you can monitor the corre­sponding input signals from MASTER L & R and MASTER PHONES (page 17).

This section describes connecting musical instruments and microphones to the INPUT 1-8 jacks and
adjusting the level of input signals.

To connect devices to INPUT 1 & 2, set the [(HI-Z)/LINE/MIC] switch to a setting that is appro­priate for the connected devices (page 8).

You can insert an effects processor via the INSERT I/O jacks into analog input channels 1 and
2 (INPUT 1 & 2).

2. Connect the musical instruments and microphones to the INPUT 1-8 jacks.

3. Adjust the [GAIN] control for the INPUT jacks to which you connected the musical instru­ments and microphones.

4. Adjust the [MASTER VOLUME] control and the [MONITOR VOLUME] control.

INPUT 1 & 2 jacks:

In order to record at the optimal level, adjust the [GAIN] controls so that the [PEAK] indicator for
each input flickers briefly when you play at your loudest level.

INPUT 3 - 8 jacks

Observe the input level meters of your DAW or audio sequencer while adjusting the [GAIN] controls
to raise the level to a point just before the signal starts clipping.

16

Direct Monitoring

Through the MASTER L & R jacks and the MASTER PHONES jack, you can directly monitor signals
input at INPUT 1-8 jacks or COAXIAL or OPTICAL DIGITAL STEREO INPUT jacks.

When an audio input signal, such as a guitar or vocal signal, is output through the computer,
latency (delay) may occur. However, this Direct Monitoring function enables you to monitor a sig­nal before it is output to the connected computer, and thus avoids latency in the monitoring signal.

NOTE

If you wish to record to the DAW your vocal or musical instrument performance accompanying
the DAW’s background tracks, while listening to the sound through the i88X, turn off the mon­itoring function on the DAW. Otherwise, you will have to listen to a delayed sound (from the
DAW) and to a non-delayed sound (monitoring sound from the i88X) at the same time, result­ing in a garbled sound.

2. Using multiple mLAN devices

Connect the mLAN (IEEE1394) connector on the IEEE1394-compatible computer and the mLAN
(IEEE1394) connector on the 01X Digital Mixing Studio and on the i88X using IEEE1394 cables.
In mLAN Graphic Patchbay (refer to the mLAN Graphic Patchbay Online Manual), route the
audio and MIDI signals between the computer and the i88X and set up the wordclock.

This system enables you to make best use of the 01X Digital Mixing function (up to 28-channel
digital mixing). Using eight A/D inputs on the 01X and eight A/D inputs on the i88X enables you
to transfer 16-channel analog audio data to the 01X. Eight D/A outputs on the i88X are avail­able, as well as MONITOR OUT (stereo) and STEREO/AUX OUT (stereo) on the 01X. These ana­log interface and the i88X COAXIAL and OPTICAL DIGITAL STEREO jacks expand analog and
digital input and output on the 01X.

English

NOTE

Sampler

The number of available input and output channels may vary depending on the specific mLAN
devices connected. For the best performance, it is recommended that you connect up to four
mLAN devices (including a computer) in a network. If the network contains an mLAN device
that is only compatible with a low transfer rate (200 Mbps (S200)), the number of devices and
channels available for connection will be reduced.

Troubleshooting

If you encounter a problem...

If you hear no sound or a strange sound, first check the items described below and take appropriate
action. If the problem persists, consult your Yamaha dealer.

■ No sound or very low volume level

• Are speakers or headphones connected correctly?

English

• Is your amp and other external devices turned on?

• Is the signal from the external device being input?

• Are all the level settings (of any tone generators, playback devices and the application itself) appropriate?

• The connection cable from the external device may be broken.

• Is the wordclock setting correct for both the i88X and the external device(s)?

............Refer to “Connecting a Computer to an mLAN device via mLAN” in the Installation

Guide, and “Wordclock Settings” in the mLAN Graphic Patchbay Online Manual.

• (For Windows) Is mLAN (mLAN Driver) set to “ON”? From the task bar, right click on the mLAN Manager

(mLAN icon).

• Are the other settings of mLAN appropriate? ........Refer to “Unable to communicate via mLAN (page 23).”

• If there are more than four devices (including a computer) on the network, the limit of the IEEE1394 BUS

bandwidth may be exceeded.

• The limit of the IEEE1394 BUS bandwidth may have been exceeded. Check the current bandwidth using

mLAN Graphic Patchbay, and disconnect some devices if necessary.

.......................................... Refer to “Menu Bar” in the mLAN Graphic Patchbay Online Manual.

• If there is an mLAN device that supports only S200 on the mLAN network, the IEEE1394 BUS bandwidth
