Is the NETWORK connector on the MTX3 properly connected to your computer?
Have you specified the correct UNIT ID using the [UNIT ID] rotary switch and DIP switches 1 and 2
on the rear panel? Could the UNIT ID be conflicting with another device?

cally assigned according to the UNIT ID.

Could rear panel DIP switch 5 (PANEL LOCK) be set to “LOCK”? Change this to “UNLOCK” to
defeat the panel lock function. If you are still unable to operate the device, contact your Yamaha
dealer.

Are you using an appropriate cable, and is the MTX3 correctly connected to the DCP?
Did you power-cycle the MTX3 after connecting the DCP? The DCP will be detected when the
power is turned on.
Did you assign the DCP’s ID and parameters correctly in MTX Editor?
Is termination turned on for the last-connected DCP?
Could nine or more DCP units be connected? A maximum of eight DCP units can be connected to
one MTX3.
Could the total cable length from the MTX3 to the last control panel be exceeding 200 meters?
The DCP’s LEDs are dim Did you set the DCP’s LED brightness appropriately in MTX Editor?

Did you use an appropriate cable to make proper YDIF connections between the MTX3 and other
devices in the MTX system? Also, is the power to the YDIF-connected devices turned on?

uler?
Are playable audio files saved in the specified folder?

Are you using an SD memory card type and format that is supported? Refer to the “Specifications”
page, and use a supported card.
Is the SD memory card inserted correctly? Turn off the power of the MTX3, re-insert the card, and
then turn the power on again. If the [SD/ACT] indicator does not light and the card is not detected, it
may be that the card is damaged.
Preset does not switch at the time
specified by the scheduler
The MTX3’s clock is set by sending clock data from the computer via MTX Editor to the MTX3.
Make sure that the computer’s clock is set correctly.
Have you made the correct scheduler settings in MTX Editor? If the [SCHEDULER] indicator is not
lit or blinking, it may be that settings were not made correctly in MTX Editor.

An error has occurred. The alert number is shown in the front panel [PRESET] display; refer to
“Alert list” on page 21 to determine the content of the error and take the appropriate action.

cable.
