I-Tech
HD Series offers amazing
power, light weight and ease of use for touring
sound applications. Unlike other amplifi ers, it
includes onboard high-defi nition DSP, an LCD
control screen, and a built-in network
connection.
Modern power amplifi ers 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 amplifi ers 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 amplifi er.
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 effi ciently to the load
and provides low AC current draw.
• Onboard high-defi nition DSP with 24-bit,
192 kHz Cirrus Logic SHARC A/D and D/A
converters. Advanced IIR fi lters and linear-
phase FIR fi lters.
• Pushbutton presets simplify setup. Custom
presets for various loudspeakers can be
down loaded.
• AES/EBU digital audio input.
• EtherCon
®
Ethernet con nector for HiQnet™
control or CobraNet digital audio transport.
This “Single Plug” connection allows HiQnet
protocol and CobraNet digital audio through the
same CAT 5 cable.
• Analog and digital thru connectors.
• LCD Control Screen is used to adjust the
amplifi er’s attenuation and muting, confi gure
the amp, set up and view error monitoring, and
recall DSP presets to reconfi gure the amp for
various applications.
• Comprehensive array of indicators provide
accurate diagnostics: Power, Data, along with
Ready, Signal, Clip, Thermal and Fault for each
channel.
• AC mains indicator in power switch glows
green when AC power is present.
• Front-panel USB connector accepts a USB
drive to transfer presets from the drive to the
amplifi er DSP, and vice versa.
• 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 specifi cations.
