I-Tech 4x3500HD Four-channel, 4000W @ 4Ω Power Amplifier

Crown I-Tech 4x3500HD Amplifier

The I-Tech 4x3500HD is Crown’s flagship high-powered tour sound amplifier, designed for ultimate flexibility, efficiency, and precision. It is the industry’s first amplifier to feature four fully routable inputs (Analog, AES3, and CobraNet™) to any of its four outputs, making it ideal for touring, large-venue, and professional live sound applications. Each channel is equipped with OMNIDRIVEHD™ processing, including LevelMAX™ limiters and support for linear-phase FIR filters, as used in JBL V5 loudspeaker tunings. Combined with Crown’s patented Class-I technology, the I-Tech 4x3500HD delivers consistent, uncompromising power output across all channels.
