Symptom Possible causes Possible solution
Power does not come on. Time between turning the power on/off is too short. Wait about 20 seconds after turning the power off before turning it back on again.
No sound.
Routing is not appropriate.
On the HOME screen, if there is a signal in the INPUT meter but no signal in the SP Output Meter,
check if the signal is routed to SP OUT under ROUTER in the settings.
Level is low in DSP.
Check the INPUT level on the ROUTER screen, and raise the level if it is too low.
No sound, or intermittent sound. Too many Dante devices in the daisy chain for the current
latency settings.
With the default setting (1 msec), a single daisy chain can have up to 10 units. When connecting
more than 10 units, use an L2 switch (that supports Giga-bit Ethernet) to create branches in the net-
work.
Volume becomes low suddenly.
Protection function is active because the amp is too hot, trigger-
ing the limiter.
In such cases, “THERMAL” is displayed on the HOME screen. To reduce the amplifier temperature,
reduce the output level and improve the ventilation around the rear panel. Additionally, shield the
rear panel from direct sunlight.
Sound is interrupted suddenly.
Protection function is active because the amp became hotter,
triggering the mute function.
In such cases, “MUTED” is displayed on the HOME screen, and at the same time the [POWER] indi-
cator flashes. To reduce the amplifier temperature, reduce the output level and improve the ventila-
tion around the rear panel. Additionally, shield the rear panel from direct sunlight. The system will
recover once the temperature goes down.
The speaker units are damaged.
If there is no sound even though MUTED is not displayed on the HOME screen and there is a signal
in the SP Output Meter, the speaker units might be damaged. Please contact your Yamaha dealer.
