•
BRIDGE [ON] button
If this is enabled, the amp will be in BRIDGE output mode.
In BRIDGE mode, adjacent odd-numbered and even-numbered channels are bridge-connected to operate
as a high-power amp.
•
CHANNEL SLEEP [ON] button
If this is enabled, the amp of that channel will sleep. By putting unused channels to sleep, you can
conserve electrical power and reduce excessively high temperatures.
This is different than the Auto Sleep setting in the "Properties" area of the "Project" sheet.
•
"LOAD MONITORING"
Here you can make settings for monitoring the speaker output impedance in order to determine whether
the output has been interrupted by an electrical short, breakage, or speaker malfunction. By outputting a
pilot tone, the impedance can be detected in a stable manner without relying on the audio signal output.
This is not shown for channels that are specified as a Hi-Z connection.
◦ [ON] button
Switches LOAD MONITORING on/off.
◦ OSCILLATOR [ON] button
Specifies whether a pilot tone is output.
A pilot tone from an external input can also be used to detect the impedance.
◦ OSCILLATOR [Level] knob
Specifies the output level of the pilot tone.
◦ IMPEDANCE [Detection Freq.] knob
Specifies the frequency for which impedance is detected. The [Impedance] field below shows the
measured impedance.
◦ IMPEDANCE [High Threshold] knob/indicator
Specifies the upper threshold of impedance that is measured. If the specified value is exceeded, it
