METER PANEL QUICK GUIDE
Each meter panel has a Clock, three Stereo Bargraph Meters, and an Event Timer.
CLOCK
The clock expresses time in Hours:Minutes:Seconds in either 12- or 24-hour display format. See page 2-5 for
information on setting the clock and for the clock board’s DIP switch functions.
EVENT TIMER
The event timer displays time in Minutes:Seconds:tenths of seconds. See page 2-6 for information on setting
the timer board’s DIP switches and page 3-11 for the event timer control functions.
BARGRAPH METERS
Three horizontal stereo bargraph meters display Program 1, Program 2, and either Cue or a source selected on
the Meter Switcher mdoule. The first two meters, from the left, provide separate level monitoring for the Program
1 and Program 2 buses. The third meter, Meter Switcher, shows the cue bus level (when Cue is active), or a
selected source (an external input, the Send bus, the Telco Record Base Mix, Program 3 or Program 4) as set by
the Source Selector buttons in the Aux Meter section of the Meter Switcher module (see page 3-11).
Each bar segment, from 0 down to -30, represents a 1 dB level change between bars. From -30 to -57, each bar
represents a 3 dB difference in level.
The bars are green from -57 up to -20. The -20 level is equivalent to a 0 VU setting on a mechanical meter. With
a properly set up console this results in a +4 dBu analog output (analog outputs can be level trimmed, however).
From -20 up to -3 the LEDs are yellow. Levels should normally peak in this area.
The 0, -1, and -2 bars are red to indicate the signal is dangerously close to clipping. To prevent digital distortion
on the outputs, the red bars should rarely, if ever, light up—especially the 0 bar since this indicates the signal is
at, or beyond, Full Scale Digital (the digital clipping point).
