Description
The ARC Audio Cu 4.4 is a four-channel Class A/B reference amplifier for premium front-stage, active, bi-amplified, and multi-speaker systems. It is rated at 110 watts RMS per channel into 4 ohms, 175 watts RMS per channel into 2 ohms, or 350 watts RMS from each bridged channel pair into 4 ohms.
The amplifier supports four-channel, three-channel, and two-channel system configurations. ARC Audio's Copper Series design incorporates ULF (Ultra-Low Feedback) signal architecture and TTB (Thermal Tracking Bias) technology. Microprocessor-controlled internal cooling manages operating temperature, while the crossover-bypass function supports direct operation from an external DSP.
