Crown Amp Rack for JBL Vertec 4886

This Crown Amp Rack – AudioRACK features two built-in I-Tech 12000HD amplifiers. Designed to work in conjunction with JBL VERTEC 4886 Sub Compact speakers. The Crown I-Tech Series offers amazing power, light weight and ease of use for touring. Onboard DSP (Digital Signal Processing) provides a wide array of signal processing (compression, limiting, filters, etc). This greatly reduces the need for rack components and rack wiring. The DSP features 24-bit, 96 kHz A/D and D/A converters. Also, 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.

Additional Benefits

Additionally, the Global Power Supply works anywhere in the world, and offers PFC (Power Factor Correction). Also 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. Also, boasting the highest output voltage in the industry (200V peak) 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. An AC mains indicator in the power switch glows green if AC power is present. Furthermore, analog and digital thru connectors are provided. Advanced protection includes a management controller and two discrete thermal zones with variable-speed, forced-air cooling.
