Pre-Owned amplifiers in excellent condition - with just over 1000 hours on each unit

Crown’s I-Tech HD 12000HD offers amazing power, light weight and ease of use for touring sound applications. Crown I-Tech HD Series features a road-warrior-inspired front panel USB slot for load and recall of amplifier settings. Chief engineers can simply hand pre-loaded USB keys to entry-level staff who can now quickly, cost-efficiently and accurately configure entire racks by inserting the correct key and pressing the load button. A patent-pending intuitive front panel work surface with LCD display provides fast and easy menu-based system setup and full amplifier diagnostics.

Protected by a rugged 2U chassis, the I-Tech HD weighs in at a lightweight 30 lbs. (13 kg.) but its proven, Class-I output design packs a heavyweight punch to deliver massive amounts of power while generating minimal heat. Crown Audio’s patented Power Factor Correction (PFC) techniques allow I-Tech HD to draw current from the mains more efficiently, which in concert with the Class-I output enables I-Tech HD to provide the highest output voltage available and a clearly audible difference driving high-performance loudspeakers


  • Global Power Supply with PFC (Power Factor Correction) works anywhere in the world.
  • High power density, up to 9000 watts in a 2U chassis.
  • Highest output voltage in the industry (200V peak) provides clean transient peaks.
  • 3rd-generation patented Class I (BCA®) circuitry couples power efficiently to the load and provides low AC current draw.
  • Onboard high-definition DSP with 24-bit, 192 kHz Cirrus Logic SHARC A/D and D/A converters. Advanced IIR filters and linear phase FIR filters.

Crown I-Tech I-T4000 And Crown I-Tech I-T6000: The I-Tech Series At 125th AES 2008 02:25

Without even getting into its power or its front panel and menu features, the crowning achievement of Crown's I-Tech series, featuring the Crown I-T4000 and the Crown I-T6000, is that its able to reach across party lines and bring digital and analog together. In fact, in a live setting where a failure on either end could really cause disaster, analog and digital even have each other's backs, making sure that the I-Tech series amps run like well oiled machines.
