Description
The ARC Audio Copper CU4.4 is a four-channel Class A/B reference amplifier for premium front-stage, active, bi-amplified, and multi-speaker systems. It produces 110 watts RMS per channel into 4 ohms or 175 watts RMS per channel into 2 ohms. Each channel pair can be bridged to deliver 350 watts RMS into a 4-ohm load.
The four-channel layout can power front and rear speakers, a passive component system, or separate drivers in an externally processed active system. Its 10 Hz–75 kHz frequency response provides wide-bandwidth operation, while the selectable input configuration and bypassable front end allow the installer to use the onboard signal section or route control through an external DSP.
An adjustable 55 Hz–5.5 kHz crossover range supports multiple system assignments. The CU4.4 is a dedicated analog amplifier and does not include an internal DSP.
