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 problem, initialize the memory.
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 problem, initialize the memory.
20
OUTPUT CURRENT OVER [*]
Protection of the circuitry has been enabled in the
device because there is: 1) a shor t 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.
S i n c e c o n t i n u o u s h i g h - p ow e r o u t p u t c a u s e s h i g h
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.
S i n c e c o n t i n u o u s h i g h - p ow e r o u t p u t c a u s e s h i g h
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.
55
USB:I/O ERROR
Cannot read/write the USB flash drive properly.
Confirm that the USB flash drive you are using works
properly with a computer. Use a tested USB flash drive.
Refer to Yamaha Pro Audio global website (http://www.
yamahaproaudio.com/) for tested USB flash drive.
56
USB:STORAGE FULL!
The remaining capacity of the USB flash drive is not
sufficient.
Make sure the USB flash drive has enough free space.
58
USB:LOAD ERROR
The USB flash drive has been unplugged during
access. A failure has occurred in reading files from
the USB flash drive. Data in the PX amplifier may be
corrupted or lost.
Try again. The [USB] indicator flashes when the USB flash
drive is being accessed. Do not unplug the USB flash drive
during this time.
65
INCOMPATIBLE DATA LOADED
The recalled preset includes incompatible settings, so
the setting has reverted to the default. This also results
when a file stored from PX5/PX3 in Power Boost mode
has been restored.
