Integrated Networking
IQ
®
Network provides the most powerful amplifier
control and monitoring available, and it’s tightly
integrated into I-Tech. I-Tech amps connect directly
to IQ Networks, providing Crown’s legendary IQ control over
industry-standard Ethernet hardware. Using mature, off-the-shelf
technology, Crown’s TCP/IQ
TM
protocol ensures reliable, easy to
implement, and inexpensive network connectivity.
CobraNet digital audio options are available with Crown’s proprietary
“one-click” solution that integrates both TCP/IQ and CobraNet digital
audio with a single network connection.
I-Tech puts you in the digital domain...
Attenuation:
Displays attenua-
tion in dB and on a bar meter.
Example Basic Controls
CH1 Input Sensitivity:
Sets the
input sensitivity of Channel 1.
Preset:
DSP settings tailored for
a specific application.*
Peak Voltage Limiter:
Sets output
voltage limits, from 0 to 200 VOLTS
PK
.
Example Advanced Controls
Pink Noise Generator:
Adjust the
noise level from 0 dB to -100 dB
(off) in 0.5 dB steps.
Monitor:
Select thermal head-
room, AC line voltage, load, error
log, operating hours, amplifier
firmware version, date code, or
serial number.
I-Tech’s front panel LCD screen provides two valuable benefits
never before seen on a professional amplifier: fast and easy
menu-based setup and full amplifier diagnostics.
Basic menu controls include Bridge, Y Input, Recall preset, LCD
contrast, and Input sensitivity. Advanced menus include
Attenuator limit, Attenuator link, Clip limiter, Output voltage lim-
iter, Output power limiter, Pink noise generator, Monitor, Input,
Max input, Power-up options, and more.

*I-Tech comes with JBL VerTec tunings preloaded into presets.
Integrated DSP
Crown engineers took advantage of the best-available
technology and years of expertise to build a DSP section
specific to I-Tech—one that performs with the audio quality
you have come to expect from the best outboard analog
signal processing components.
I-Tech’s powerful DSP is also easy to set up, with your custom
settings and factory-designed tunings easily loaded and recalled
via onboard presets. By designing the DSP specific to I-Tech, with
the latest technology and through careful attention to detail, Crown
engineers designed a DSP section that achieves a level of accura-
cy and ease of use that is simply not possible with outboard DSP
processors.
