t[PROTECTION] indicator
When the protection system is active, this indicator will light red. The protection circuit will operate in the following situa-
tions.
If the amplifier overheats and the output limiter operates
The speaker output will be attenuated if the heat sink of the amplifier section exceeds 80°C (80%), and will be muted if
the heat sink exceeds 90°C (90%). The [PROTECTION] indicator will light at 80°C (80%) or higher.
If the power supply overheats and shuts-down
The fan will rotate at high speed if the power supply section exceeds 90°C, and the analog circuits will shut down if it
exceeds 100°C. The [PROTECTION] indicator will light only if shut-down occurs.
The thermal meter in the METER screen and in Amp Editor indicates the heat sink temperature of the amp section.
The temperature of the power supply section is not shown.
If the load falls below 0.5 ohms
If a short occurs and the load falls below 0.5 ohms, the speaker output will be muted, and muting will be cleared approx-
imately 1 second later.
If DC output is detected
The speaker output will be muted, and the power supply section will shut down.
If the power supply malfunctions
The speaker output will be muted.
If ultra-high frequencies, overcurrent, excessive total current, or maximum current is detected
The speaker output will be compressed.
y[BRIDGE] indicator
This will light green if the amplifier mode is set to Bridge.
u[PARALLEL] indicator
This will light orange if the amplifier mode is set to Parallel.
i[MUTE] indicator
This indicator will light red if muting is turned on by the [MUTE] button or from Amp Editor. When the power is turned on,
the output signal will also be muted and the indicator will blink red until audio begins being output.
•Even if mute is off, this indicator will blink if Solo was turned on from Amp Editor, or when the output has been muted by
the protection circuit.
o[MUTE] button
By holding down the [MUTE] button for one second or longer, you can turn muting on/off for that channel. When muting
turns on, the [MUTE] indicator will light. By holding down the [MUTE] button when the Solo function is turned on from
Amp Editor, Solo will be defeated.
!0 [ALERT] indicator
This will light to indicate an alert related to the amplifier’s audio signal. If an alert for a specific channel has occurred, the
indicator of the corresponding channel will light; for other alerts, the indicators of both channels will light. At this time, the
alert message will appear in the upper part of the display.
!1 [CLIP] indicator
When the signal of the speaker output’s power amp section exceeds the clipping level, this indicator will light and the output
signal will be compressed.
!2 [SIGNAL] indicator
This will light green when the level of the signal being output from the [SPEAKERS] jack exceeds 1 Vrms (equivalent to
0.2 W into an 8 ohms load, 0.4 W into a 4 ohms load or 0.8 W into a 2 ohms load).
