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?

• 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

may be reduced and its limit exceeded. Reduce the number of mLAN devices connected to the network, or

disconnect some devices as necessary.

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

■ Distorted sound

• Is the [GAIN] control set correctly? ...................................................................................Refer to page 16.

• 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.

• Make sure audio data was recorded at an appropriate level.

■ Noise is audible

• Is the latency setting of the mLAN Driver appropriate?

...........Refer to “mLAN Driver Setup” and “ASIO mLAN Control Panel” in the Installation Guide.

• (For Windows) Setting Hyper Threading to off in the BIOS settings may solve the problem.

• 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.

• If the speed of your computer's hard disk is slow, problems may occur during recording and playback.

• If you connect/disconnect the LAN, USB or the cables to the mini jacks terminals on the Macintosh you are

using when using mLAN, some noise may be caused and/or data may be cut off. Make sure that you do

not insert or unplug any connections when using mLAN.

• Is the number of audio channels appropriate? The amount of audio channels that can be used simulta-

neously differs depending on the computer capacity and speed.

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

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

• Is the sampling rate (wordclock) appropriate? A high sampling rate can be the cause of the noise depend-

ing on the computer capacity and speed.

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

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

• Make sure that the appropriate number of devices is connected to the computer. Connection of too many

devices may cause noise, depending on the capacity of the computer.

• Are there any noise-producing devices (such as those containing power inverters, etc.) near the cables?

Move all cables away from any possible noise sources.

• Make sure the mLAN cable is not damaged. Cables that do not satisfy IEEE1394 standards may cause noise.
