Possible solution
01–06
SYSTEM ERROR
The device has not started up correctly.
Turn the power off, and then turn back on after waiting at least 6 seconds. If this
does not solve the problem, initialize the memory. Should this also fail, contact
your Yamaha dealer.
07
SP PRESET DATA LOST
The speaker preset file is corrupted.
Load the preset file again from a USB flash drive. If this does not solve the prob-
lem, initialize the memory. Should this also fail, contact your Yamaha dealer.
08
WRONG SP PRESET DATA
The speaker preset data in the device are corrupted. Failure
might have occurred in loading a speaker preset file from the USB
flash drive.
Load the preset file again from a USB flash drive. If this does not solve the prob-
lem, initialize the memory. Should this also fail, contact your Yamaha dealer.
20
OUTPUT CURRENT OVER [*]
Protection of the circuitry has been enabled in the device because
there is: 1) a short at a speaker terminal, amplifier terminal, or
wire; or 2) the amplifier load is excessive. (*: channel name)
Make sure that the speakers are not damaged and the total impedance is not too
low, and inspect the connection of the speaker cables.
21
AMP TEMP TOO HIGH
The temperature in the amplifier unit of has exceeded the allowed
limit. The output load is excessively high. This tends to occur
when the load of only channel A is high.
Since continuous high-power output causes high temperatures, lower the output
level. If the load is biased on the channel A, disperse the load by connecting to
the channel B or other amplifiers. Also, check whether dirt or a foreign object
could have clogged the cooling fan, and clean the fan itself if necessary.
22–24
LIMITED BY OVERHEAT
The amplifier temperature is excessively high, and so the limiter
for the output has been activated.
Since continuous high-power output causes high temperatures, lower the output
level. Also, check whether dirt or a foreign object could have clogged the cooling
fan, and clean the fan itself if necessary.
25
MUTED BY OVERHEAT
The amplifier temperature is excessively high, and so the output
level has been lowered.
Since continuous high-power output causes high temperatures, lower the output
level. Also, check whether dirt or a foreign object could have clogged the cooling
fan, and clean the fan itself if necessary.
26–27
POWER SUPPLY TEMP TOO HIGH
The amplifier temperature is excessively high, and so the cooling
fan has been set to the maximum speed and the limiter has been
activated.
Since continuous use may cause malfunction in the power supply unit, stop using
immediately, or lower the output level. Also, check whether dirt or a foreign object
could have clogged the cooling fan, and clean the fan itself if necessary.
33
SPEAKER IMPEDANCE TOO LOW [*]
The speaker impedance is excessively low. (*: channel name)
Make sure that the speakers are not damaged and the total impedance is not too
low, and inspect the connection of the speaker cables.
50
USB:COMPATIBLE DEVICES NOT
FOUND
A USB flash drive has not been installed.
Install an appropriate USB flash drive. Refer to Yamaha Pro Audio global website
(http://www.yamahaproaudio.com/) for tested USB flash drive.
51
USB:NO FILE SYSTEM
The file system of the USB flash drive is unreadable.
Use a USB flash drive formatted properly to FAT32 or FAT16.
52
USB:FILE NOT FOUND
The object file has not been found.
Make sure the relevant file is contained in the USB flash drive and try again.
53
USB:ILLEGAL FILE
Illegal file.
Replace with an appropriate file and try again.
54
USB:INCOMPATIBLE FORMAT
Incompatible file format.
Replace with an appropriate file and try again.
