The I-Tech 4x3500HD is a high-performance four-channel touring amplifier built for large-scale live sound and installed systems requiring maximum power and control. It features a true Ethernet backbone for fast, reliable networking, along with a color LCD for onboard diagnostics and preset management. Integrated SLM (Sweep Load Monitoring) provides advanced system-level diagnostics, while a front-panel USB port allows easy preset transfer. Performance Manager software simplifies configuration and system-wide control, and extensive connectivity options—including analog, AES, CobraNet, HiQnet, and Ethernet—offer unmatched flexibility.

Powered by BSS OMNIDRIVEHD DSP with both IIR and linear-phase FIR filters, the amplifier delivers precise processing and exceptional sound quality. LevelMAX peak voltage and RMS limiters work together for smooth, accurate performance, while patented Class-I (BCA) circuitry ensures high efficiency and low AC draw. With a universal global power supply (100–240VAC), professional-grade connectors, and robust energy reserves, the I-Tech 4x3500HD is engineered for demanding touring and mission-critical audio applications.
