Crown Audio I-T5000 HD Manuel D’Utilisation

Your Crown amplifi er provides extensive 
pro tection and diagnostic capabilities, including 
thermal level control, fault indicators, high-pass 
fi ltering, DC protect, AC under/over volt age 
protection, inrush limiting, and variable-speed 
fans with tachometer feedback. Microprocessor 
monitors fans, and signals an error via System 
Architect if fans are not operating.

If the amplifi er becomes too hot for safe 
opera tion, the TLC will engage the input 
compressor and the clip LED will illuminate. By 
compress ing the input, the amplifi er will not 
generate as much heat and will have a chance to 
cool down. The degree of compression is 
proportional to the amount of overheating. This 
feature allows the show to go on, rather than 
having the amplifi er shut down, and only occurs 
in extreme situations.

If the current draw of the amplifi er exceeds safe 
limits, this breaker automatically disconnects the 
power supply from the AC mains.

Thanks to its global power supply, the I-Tech 
amplifi er works anywhere in the world. There’s 
no need to reset an AC mains voltage switch, 
and no need to order a special model. The amp 
will work and meet all specs on 100V - 240VAC, 
50/60 Hz.

Crown’s Switching Power Supply minimizes the 
amplifi er’s weight.

Typical non-switching power supplies require 
large, heavy transformers in order to produce 
the required power at the output stage. These 
transformers must be large to operate at 50 to 
60 Hz (standard AC supplied by the power 
company).

By contrast, switching power supplies can oper-
ate with a much smaller (and lighter) 
trans former because they fi rst convert the AC up 
to a much higher frequency, thereby reducing 
waste. 

Power Factor Correction (PFC) controls how 
your amplifi er draws current from the AC mains. 
Instead of drawing high-magnitude cur rent 
spikes that reduce the capacity of your power 

distro (and couple noise into other sys tem 
components), PFC draws a smooth and quiet 
current waveform that is in phase with the mains 
voltage waveform. PFC allows you to reduce the 
size and weight of your power distri bution and 
improve the performance of your signal 
processors. 

Class I (BCA, Balanced Current Amplifi er) 
Interleave technology allows high levels of 
power output without all the associated heat 
found in a conventional amplifi er. This highly 
effi cient design also provides accurate, 
uncol ored sound with very low distortion and a 
high damping factor for tight, clean bass 
response. And it can deliver more power to 
reactive loads than conventional dissipative 
designs (com fortably driving the latest high-
technology transducers). Class I also reduces 
current draw of the AC mains, providing energy 
conserva tion.
