POWER STATES AND
CURRENT/POWER DRAW
The Modul 80-S has the following power states:
•
Sleep Mode:
the Audio Module’s control electronics
receive power but amplifiers and their power
supplies are turned off to save energy
•
Idle:
the Audio Module is fully functional and ready
to play sound, but no signal is applied
•
Max. Long-Term Continuous (Max. Cont.):
playing a
pink-noise signal with a 12 dB crest factor, at an rms
current that can be sustained indefinitely
•
Max. Short-Term (Max. Short):
maximum rms
current while playing an unclipped pink-noise signal
with a 12 dB crest factor for a limited time
Power Setup and Requirements
The Audio Module can be put in
“Sleep mode” using
HOLOPLOT
Control
.
Current draw for Audio Modules is dynamic and fluctuates
as operating levels and program signal change. It is
important to understand the current ratings of each
power state and how they affect circuit breaker and cable
specifications. Use the information provided below as a
guide for selecting the gauge of cables and the circuit
breaker ratings for the system’s operating voltage.
The current draw of the Electronics Package and the current draw of the
subwoofer amplifier module are not in phase. Therefore, current draw when
powering both from a single power source is different than the sum of the
values for powering each individually.
