I-TECH SERIES
EXCELLENCE
T
he Crown
®
I-Tech Series offers amazing power, light weight and ease
of use for touring sound and installed sound applications. Onboard
DSP provides a wide array of signal processing, greatly reducing the
need for rack components and rack wiring. Onboard DSP features 24-
bit, 96 kHz A/D and D/A converters.
All models are compatible with the IQ
®
Network and TCP/IQ™
networking. Digital audio and IQ control signals connect to the amp
via a single cable (in CobraNet™-ready models). Pushbutton DSP
presets simplify the setup for various loudspeaker arrays.
The Global Power Supply works anywhere in the world, and offers PFC
(Power Factor Correction). It is a switching power supply for reduced
weight. I-Tech amplifiers have the highest output voltage in the industry
(200V peak), which provides clean transient peaks.
Features
• Global Power Supply 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.
• Onboard DSP with 24-bit, 96 kHz Cirrus Logic A/D
and D/A converters.
• Comprehensive array of indicators provide accurate
diagnostics: Power, Data, Bridge, along with Ready,
Signal, Clip, Thermal and Fault for each channel.
• Front-panel control screen with advanced diagnostics and
status information. All controls are set from the front panel.
• AES/EBU digital audio input. Ethernet connector accepts
standard network cables for TCP/IQ networking. CobraNet
input available in optional CN models (coming soon).
Analog and digital thru connectors.
