Console Display Quick Guide
The standard console display has these parts:
●
Program bus levels using two or four bar graph meters
●
Digital Clock
●
Event Timer
Figure 3-9 shows a dual meter display. A quad meter adds two meters, Program 2 and Program 3 levels,
in between the Program 1 meter and the Auxiliary meter. You can order the NetWave-16 and NetWave-24
consoles with either a dual or a quad meter display. The NetWave-8 console is only available with a dual
display.

Bar Graph Meters
A 10-character alphanumeric display below each meter identifies the displayed signal by name (Program 1,
External 1, Cue, and so forth). The left meter shows the Program 1 bus on both a Dual and Quad meter.
On a Quad Meter, the two middle meters show the Program 2 and Program 3 buses. The right meter
(Auxiliary) shows the levels of the source selected using the Aux Meter buttons on the Monitor Control panel
(Figure 3-6). Note that the Auxiliary meter can also automatically show levels of the cue bus whenever cue
is active (a feature set or disabled using a Monitor & Output board setup switch).
Figure 3-10 shows a detailed view of a bar graph meter. The meter is calibrated in dBFS (decibels Below Full
Scale Digital) with the far right end of the meter showing 0 dBFS, the maximum output level of the console.
In analog terms, 0 dBFS is equivalent to an analog output level of +24 dBu. Thus, the -20 dBFS bar (the last
green LED segment in the middle of the meter) is equivalent to a 0 VU setting on a mechanical VU meter. A
-20 dBFS signal on the meter results in a +4 dBu analog program output.
Figure 3-10. RMXdigital Bar Graph Meter
The bars from 0 to -30 dBFS represent a 1 dB level change between bars. From -30 to -57, each bar
represents a 3 dB difference in level. Bars are green from -57 up to -20 (equivalent to a 0 VU level on a
mechanical VU meter). From -19 to -3 the bars are yellow. Peak signal levels should always fall within this
range. The 0, -1, and -2 bars are red to indicate the signal is dangerously close to digital clipping.
To prevent digital distortion on the outputs, the red bars should rarely, if ever, light up—especially the 0
bar—as it indicates the signal is at, or is attempting to go beyond, Full Scale Digital (the absolute maximum
digital signal possible).
The NetWave meters, by default, display levels using Peak & Average Mode where a solid bar graph shows
the Average level, with a single lit bar, typically 6 to 10 dB higher than the top of the Average bar graph,
showing the peak level of the signal. The meters can alternately be set to the Average-only Mode where a
