7.5. LOAD MONITORING
This constantly monitoring the impedance of the connected speaker, and displays an alert message if an
abnormal value is shown. You can check the impedance in the LOAD MONITORING page of the HOME screen.
NOTE
• Load monitoring does not operate in the following cases
◦
For a high-impedance connection
◦
When the amp is in standby mode
◦
When the channel is in the Channel Sleep ON or Auto Sleep On state
①
ON/OFF
If this is ON, the speaker’s impedance is detected.
②
OSC ON/OFF
If this is ON, an audio signal is output for detection.
NOTE
• Turn this OFF if a signal for detection is being sent from a device (e.g., mixer) connected before this
unit.
• If
①
is OFF, a signal for detection is not output even if OSC is ON.
③
OSC LEVEL
This specifies the level of the audio signal for detection.
NOTE
• Gradually raise the OSC LEVEL and check that the impedance value is shown in the HOME screen.
However depending on the characteristics of the speaker, there might be cases in which the
impedance cannot be detected even if the level is raised to the maximum.
• If you jumped from the HOME screen’s LOAD MONITORING page directly to this LOAD MONITORING
screen, you can move between them at a touch by alternately pressing the [
](back) key and the
main knob.
④
DETECT. FREQ. (DETECTION FREQ.)
This specifies the frequency of the audio signal for detection.
