RTI 10-210860-18 DSP Matrix Amplifier AMP-4-125, 4-Channel 125W or 2-Channel 100V / 250W

Bring reliable, room-by-room audio control to commercial, hospitality and security-focused environments with the RTI AMP-4-125 DSP Matrix Amplifier. This pro amplifier combines flexible output modes and onboard DSP so installers can drive low-impedance speakers (4–16Ω) or transformer-coupled 70/100V lines with the same unit — 125W per channel in four-channel mode or 250W per channel in 70/100V mode. The AMP-4-125 accepts four balanced/unbalanced analog inputs plus a stereo S/PDIF digital input and provides fine-grain tuning with input/output EQ, delay, high-pass filters, priority and ducking for paging and monitoring scenarios. A compact 1U half-rack footprint with included rack kit keeps equipment closets tidy, while the RTI web GUI (LAN/Wi‑Fi) streamlines setup and ongoing adjustments. IP and GPIO control options make it easy to integrate audio with security, surveillance and building management systems for centralized monitoring and alerting. Ideal for hotels, retail, corporate and surveillance-driven installations — add the RTI AMP-4-125 to your next project for scalable, professional audio distribution.

• Flexible multi-zone audio that adapts to mixed low-impedance and 70/100V speaker systems for simplified installation and fewer devices
• Built-in DSP for per-zone EQ, delay, priority/ducking and presets so each area sounds optimized without extra processors
• Compact 1U half-rack design with included rack kit saves space in equipment closets while supporting up to four mono zones or two high-voltage zones
• Easy browser-based setup via RTI web GUI over LAN or Wi‑Fi speeds commissioning and reduces onsite programming time
• IP and GPIO control integration enables paging, monitoring and security system interoperability for surveillance and facility management
• Robust Class-D efficiency delivers clear power (125W per channel at 4/8Ω or 250W per channel at 70/100V) for reliable commercial audio performance
