Troubleshooting
Power does not turn on.
Did you firmly and securely connect the power cord?
Power shuts down suddenly.
Are the vents of the mixer blocked?
Since inadequate ventilation can result in overheating
the mixer, the power may be turned off automatically to
protect the system from overheating. Arrange the
ventilation for better cooling, then turn on the power
again.
No sound is heard.
Did you insert the line array speaker and spacers firmly
into the sockets?
If the speaker is not inserted into the spacers or socket
firmly, the connectors will not make sufficient contact
and no sound will be output.
Is the [PROTECT] LED lit?
If the internal power amplifier section is overloaded, the
amplifier will be muted to protect its circuits. The mixer
will automatically reset itself after a while.
Sound is distorted or noise is produced
Are the [LEVEL] controls of any relevant channels and/
or the [MASTER LEVEL] control set too high?
Is the [MIC/LINE] switch of the corresponding channel
set to MIC?
If the input level from the source is high, setting the
[MIC/LINE] switch to MIC may result in a distorted
sound. Set the switch to LINE.
Is the volume of the connected device too high?
Lower the volume of the external device.
Sound is not loud enough
Are the [LEVEL] controls of all relevant channels and/or
the [MASTER LEVEL] control set too low?
Is the [MIC/LINE] switch of the corresponding channel
set to LINE?
Turn the [LEVEL] control to the minimum (zero). Set the
switch to MIC, then slowly raise the [LEVEL] control.
Is the volume of the connected device too low?
Raise the volume of the external device.
Some settings can be controlled only from STAGEPAS
Editor.
Use STAGEPAS Editor to adjust the settings.
The high-range sounds and low-range sounds
are unbalanced.
Are the [EQ] controls raised or lowered too much?
Set the [EQ] controls to the center position.
Is the speaker properly outputting high-frequency range
signals?
If not, make sure that the line array speaker is firmly
inserted into the socket.
Cannot connect Bluetooth
The unit may be connected to a different Bluetooth
device.
Cut the current Bluetooth connection, and then connect
to the desired Bluetooth device.
You can use one Bluetooth devices to control the
STAGEPAS 1K, and a second Bluetooth device to play
Bluetooth audio remotely.
Your Bluetooth device may not support the A2DP
profile.
Use a Bluetooth device that supports A2DP.
Bluetooth audio sound cuts intermittently
The unit may be located in the vicinity of a device that
emits electro-magnetic waves at a frequency of 2.4GHz
(such as a wireless microphone transmitter, wireless
LAN device, microwave oven, etc.).
Locate the STAGEPAS 1K away from any device that
emits electro-magnetic waves.
If your Bluetooth device also features a wireless LAN
function, turn off the function, and use only the
Bluetooth function.
If a problem persists, please contact your Yamaha dealer.
