Communication Green: Loudspeaker online
Red: Information is not being received from the
loudspeaker (offline)
Mute Red: Muted
Gray: Muting Disabled/Not Muted

Channel Status Green: 0 < Voltage: Normal
Yellow: Voltage present without power (open driver
circuit)
Red: Limiting indication
Orange: Excursion indication
Gray: No voltage present at channel
Meter View
Meter View is a smaller, simplified version of Text View
(covered in the next section), with graphic meters for
informing you of power usage, voltage, fan speed, and
temperature. Figure 4.8 shows a MILO loudspeaker in
Meter View.
Figure 4.8. Meter View for a MILO loudspeaker
TIP: Unlike Icon View and Small Icon View,
Meter View does not provide the ability to
Mute, Wink or Solo a loudspeaker.
Using Figure 4.8 as a guideline, Table 4.2 explains all of the
monitoring capabilities available in Meter View for the MILO
loudspeaker.
Table 4.2 Monitoring Parameters in Meter View for the MILO
Loudspeaker
Parameter Function
Title Bar Displays the Speaker Title and/or Device Name
Amplifier
Limiting For each channel, the percentage of limiting on
the loudspeaker’s respective amplifier channels
Amplifier
Temperature Upper and lower heat sink temperature of the
amplifier
Primary/
Secondary Fan
Speeds Fan speeds of the amplifier’s cooling fans
Amplifier
Voltage For each channel, measures a range of 0-100
V. A small momentary bar marks peak voltage.
Segmented bar conditions are:
Green: 0 < Voltage < 50 V
Yellow: 50 < Voltage < 90 V
Red: 90 < Voltage < 100 V
No Bar: Voltage = 0
Entire Bar Yellow: Open driver circuit
Amplifier
Peak Power For each channel, the peak power in watts
Input Polarity Position of the loudspeaker’s Input Polarity
Switch:
+2: Polarity Switch set to Pin 2 Hot
+3: Polarity Switch set to Pin 3 Hot
Input Signal
Level Measures 0-10 V and indicates the following
conditions:
Green: 0 < Signal Level < 8 V
Yellow: 8 < Signal Level < 9 V
Red: 9 < Signal Level < 10 V
CAUTION: The Amplifier Limiting indicator
corresponds to the intensity of the LEDs on
the rear of the loudspeaker itself. In general, if the
Amplifier Limiting indicator is orange or red, the
loudspeaker may distort and may not operate in a
linear manner, and routinely driving a loudspeaker
at this level can shorten the lifespan of its
amplifier and drivers. Intermittent limiting or over-
excursion, however, will probably not result in sonic
degradation or damage to the loudspeaker.
Since each type of loudspeaker behaves differently
in response to limiting and over-excursion, consult
the loudspeaker’s operating instructions for more
details on its limiting capabilities.
