The I-Tech 4x3500HD amplifier is the industry's first high-powered tour sound amplifier featuring four inputs, Analog, AES3, and CobraNet?, fully routable to any one of 4 outputs. Each channel features a complete compliment of OMNIDRIVEHD? Processing, including the acclaimed LevelMAX? Limiter Suite, and support for linear phase FIR filters as used in the latest JBL V5 loudspeaker tunings. Combine that with Crown's patented Class-I technology delivering uncompromising power output across all four channels, and it's easy to see why the I-Tech 4x3500HD is the flagship tour sound amplifier from Crown.
