There is insufficient headroom, especially when EQ
boost is applied.
Use the EQ attenuator function to lower the level.
An input signal is being input, but there is no
monitor output.
Could the DIMMER be applied?
Could the MONITOR CH be assigned even though
its output port has not been connected to an external
device?
Signal is delayed.
Check whether the delay setting for each INPUT
channel and OUTPUT PORT is set correctly.
Rotating a MIX knob does not change the send level
to the MIX bus.
Is the TO MIX SEND ON/OFF button turned on?
Is the MIX [ON] key turned on?
Is the MIX bus set to VARI type?
If the send point is set to POST, could the fader have
been lowered?
Cannot save scene memory or various library data.
Are you attempting to save the data to a read-only
scene/library or a protected scene?
Could user level restrictions have been specified?
Cannot save to a USB flash drive.
Could the USB flash drive be protected?
Does the USB flash drive have enough free capacity
to save the data?
When formatting the USB flash drive, format it in
FAT32 or FAT16 format.
Could the recorder be playing back?
Cannot transmit or receive MIDI data.
Is the MIDI PORT selected correctly?
Are the transmission and reception modes and chan-
nels selected correctly?
Has an event corresponding to the particular Pro-
gram Change message been specified?
When you recall a scene, some channels/parameters
are not updated.
Could that channel or parameter be set to Recall
Safe?
Could FOCUS be set in such a way that the channels
or parameters will not be updated?
Could user level restrictions have been specified?
You turn on a CUE button in the EFFECT EDIT screen,
but it is automatically defeated.
This is defeated automatically when you switch
screens in the display.
When you recall a scene, it takes a certain amount of
time for the faders to stop.
Could you have specified a fade time?
The panel LEDs or LCD display are too dark/too
bright.
This can be adjusted in the SETUP screen.
Signal level of a specific frequency is low.
Could the EQ gain be turned down excessively?
Routing a signal through a GEQ or EFFECT will
delay it relative to other signals. If this signal is mixed
with another signal that is routed via a different signal
path, a comb filtering effect will cause the level of a
specific frequency to be decreased.
Cannot control an I/O device.
Are the rotary switch and DIP switches on the I/O
devices set correctly?
Does the channel being controlled match the chan-
nel on the I/O device?
Cannot control the QL unit from QL Editor.
Is the computer connected to the unit’s Network jack
correctly?
Is the network setting on the QL unit specified cor-
rectly?
For details on settings, refer to the QL Editor installa-
tion guide posted on our website.
Cannot control the QL unit from StageMix.
Is the WiFi setting in QL StageMix set correctly?
Is the unit’s Network jack on the QL unit connected to
the WiFi access point correctly?
Is the network setting on the QL unit specified cor-
rectly?
Refer to the QL StageMix Owner’s Manual on our
website.
In the LCD display, there are some black points
(unlit) or white points (always lit).
Unfortunately, this is a common characteristic of
TFT-LCDs. This is not a malfunction.
In the channel name display, because of the response
speed of the GR meter display on each channel’s
voice input and output, the indication may be weak
or different than expected.
This is a common characteristic of LCDs and not a
malfunction. Depending on the input source, this
phenomenon may be more pronounced.
