Crown Audio CT4150 Four-Channel 125W Power Amplifier
The CT4150 delivers compact, efficient amplification in a single rack unit with virtually silent operation—no cooling fan means clean audio in noise-sensitive studio environments. DriveCore™ technology fuses the drive stage directly into the power output stage, achieving over 90% efficiency while maintaining the sonic character of a refined Class AB design. Built for recording studios and production facilities requiring four independent channels of transparent, reliable amplification for monitor mixes, powered speakers, or subwoofer management.
Audio Performance & Efficiency
Each of the four channels produces 125W @ 4 ohms and 125W @ 8 ohms, with a Signal-to-Noise Ratio of 110 dB and distortion specifications of <0.05% THD and <0.05% IMD. The amplifier maintains ±0.5 dB frequency response with >70 dB crosstalk rejection, ensuring clean channel separation and transparent audio reproduction across the full spectrum—critical for accurate monitoring and mixing decisions.
Studio Integration & Connectivity
The 1 RU chassis (1.75″ × 19″ × 15.19″) integrates four independent channels into a compact footprint weighing just 10 lbs, with inputs and outputs via 3-pin and 2-pin Phoenix Connectors. Convection cooling eliminates fan noise, while the universal power supply and 15A IEC connector support international studio setups; the amplifier remains stable across 2–16 ohm loads.
