I-Tech Series Power Amplifiers
Operation Manual page 7
1 Welcome
The Crown ® I-Tech Series offers amazing
power, light weight and ease of use for touring
sound applications. Unlike other amplifiers, it
includes onboard DSP, an LCD control screen,
and a built-in network connection.
Modern power amplifiers are sophisticated
pieces of engineering capable of producing
extremely high power levels. They must be
treated with respect and correctly installed if
they are to provide the many years of reliable
service for which they were designed.
In addition, I-Tech Series amplifiers include a
number of features which require some expla-
nation before they can be used to their maxi-
mum advantage.
Please take the time to study this manual so
that you can obtain the best possible service
from your amplifier.
1.1 Features
• Global Power Supply with PFC (Power Fac-
tor Correction) works anywhere in the world.
• High power density, up to 8000 watts in a 2U
chassis.
• Highest output voltage in the industry (200V
peak) provides clean transient peaks.
• 3rd-generation patented Class I (BCA ® ) cir-
cuitry couples power efficiently to the load and
provides low AC current draw.
• Onboard DSP with 24-bit, 96 kHz Cirrus
Logic A/D and D/A converters.
• Pushbutton presets simplify setup. Custom
presets for various loudspeakers can be down-
loaded.
• AES/EBU digital audio input. Ethernet con-
nector accepts RJ-45 connector for HiQnet™ or
TCP/IQ networking.
• Analog and digital thru connectors.
• LCD Control Screen is used to adjust the
amplifier's attenuation and muting, configure
the amp, set up and view error monitoring, and
recall DSP presets to reconfigure the amp for
various applications.
• Comprehensive array of indicators provide
accurate diagnostics: Power, Data, Bridge,
along with Ready, Signal, Clip, Thermal and
Fault for each channel.
• AC mains indicator in power switch glows
green when AC power is present.
• Light weight due to aluminum chassis, spe-
cial internal construction and switching power
supply.
• Thermal management controller and two dis-
crete thermal zones with variable-speed fans,
forced-air cooling.
• Advanced protection circuitry guards
against: shorted outputs, DC, mismatched
loads, general overheating, under/over volt-
age, high-frequency overloads and internal
faults.
• Three-Year, No-Fault, Fully Transferable
Warranty completely protects your investment
and guarantees its specifications.
