Product Description

From the Manufacturer

The Crown I-Tech Series offers amazing power, light weight and ease of use for touring sound applications. Onboard DSP (Digital Signal Processing) provides a wide array of signal processing (compression, limiting, filters, and so on). This greatly reduces the need for rack components and rack wiring. The DSP features 24-bit, 96 kHz A/D and D/A converters. All models in the I-Tech Series are compatible with the IQ Network and TCP/IQ networking. CobraNet input available in optional CN models, coming soon.

The IT8000 has a power rating at 20 Hz to 20 kHz of 3500W (2-ohm dual, per channel), 4000W (4-ohm dual, per channel) 2100W (8-ohm dual, per channel), 7000W (4-ohm bridge), and 8000W (8-ohm bridge).

Pushbutton DSP presets simplify the setup. Custom presets can be downloaded into the amplifier, making it easy to configure 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 provide amazing power: up to 8 kW continuous and 10 kW peak in a 2U rack space. They have the highest output voltage in the industry (200V peak), which provides clean transient peaks. The 3rd-generation patented Class I (BCA) circuitry couples power efficiently to the load and provides low current drain.

A front-panel control screen shows advanced diagnostics and status information. All controls are set from the front panel. A comprehensive array of indicators provide accurate diagnostics: Power, Data, Bridge, along with Ready, Signal, Clip, Thermal and Fault for each channel. An AC mains indicator in the power switch glows green when AC power is present.

Input connectors include analog XLR and digital AES/EBU. Analog and digital thru connectors are provided. Output connectors are Speakon and 5-way binding posts. Advanced protection includes a management controller and two discrete thermal zones with variable-speed, forced-air cooling.

This review is from: Crown I-T8000 Power Amplifier (Electronics)

I recently added the iTech 8000 to my live rig. I have EAW LA325 tops (2) and the LA128 subs (s). Running mono I have used the iTech 4000 for smaller gigs, I run one channel for the 325's and the other for the 128's. I have contracted to do some heavier dance events over the summer so I thought it was time to get the iTech 8000 to run my LA128 double 18" subs.

The great thing about these amps is the on-board DSP, I programmed the EAW EQ curves into the amp and did a little tweaking and it's about as close to perfect as you can get. After adding the iT8k my system has really come to life, and with dance music regularly having notes as low as E0 (20.6hz) my system faithfully reproduces even the lowest notes with unbelivable punch and clairty (thanks in part to a damping factor > 5000) .

To sum these amps up: in thirty years of doing live sound for bands, corporate events and such in clubs, hotel ballrooms, and on casino stages I have never used an amp that sounded better, ran cooler or was more reliable, flexible, or programmable than these new Crowns.

The hefty price doesn't seem all that bad once you hear one. I now carry less than half the amps I used to haul, my system sounds way better (than any other amp I have ever used) and I'll probably be using these for the next 20 years.

Bottom line: if you want the best sounding and most powerful amp on the market today there is only one choice, the Crown iTech 8000, BUY ONE!
