[When each individual channel is displayed on the fluorescent display after the initial value
has been set]
• The 5th indicator (segment) from the bottom of the selected channel's level meter lights up after
completion of the initial value setting. This value is the reference value.
• The level indicator goes up and down in response to the current value. The meter shows a short state
of speaker line in the range above the reference value, and an open state in the range below it.
• Current impedance status of the selected channel can be checked in the text display area.
Current value: Displays the ratio of current impedance to the initial one in real-time.
This indicator remains unlit when the speaker line is not connected. The display
range is 0 to 9999 and over. A blank is displayed if no initial setting is or could
have been performed.
