DETAILS

The AUDAC CAP448 is a robust 4-channel Class-D 100V power amplifier designed for multi-zone commercial audio installations.

The AUDAC CAP448 is a high-performance quad-channel 100V power amplifier engineered for reliable audio distribution across multi-zone systems. Delivering 4 x 480W of continuous power, it is an ideal choice for larger installations in schools, offices, retail stores, public buildings, and hospitality environments where dependable 100V amplification is required.

This amplifier forms part of AUDAC’s CAP series, built with a no-nonsense design philosophy centred around simplicity, durability, and efficiency. Each channel offers individual gain control and a selectable 400 Hz high-pass filter, giving installers practical flexibility when tailoring zone performance. Balanced XLR inputs with link-through connectors allow for easy integration with audio matrices, mixers, or additional amplifiers.

Powered by a switching PSU and Class-D output stages, the CAP448 ensures high efficiency and low heat generation. A temperature-controlled fan keeps the unit operating reliably, while a comprehensive protection circuit safeguards against overload, DC faults, short circuits, overheating, and signal clipping. The solid 19” 2U rack-mount steel chassis ensures a long service life, even in demanding commercial environments.

Output connections are provided via 4-pin Euroblock terminals for secure, professional installation. With the ability to drive four independent 100V output zones, the CAP448 provides a dependable foundation for distributed audio systems of all sizes.
