The Integra 4125DSP is a compact four-channel professional DSP power amplifier housed in a half-width 1U chassis. It delivers 4 x 125W into both 4 and 8 ohms and supports 70V/100V distributed audio at 2 x 250W, making it a tidy solution where rack space is tight.
Why This Model Matters
Part of Integra's Professional Amplifier Series, the 4125DSP brings integrator-grade DSP to the smallest footprint in the range. Built-in Klipsch speaker presets, EQ, limiters and compressors let installers tune and protect each zone, while a web-based GUI and optional ZC1 zone controller simplify setup and control.
