The AUDAC CAP448 is a professional-grade quad-channel power amplifier engineered for multi-zone audio distribution systems in environments such as bars, restaurants, retail spaces, public facilities, and corporate settings. Delivering 480 watts per channel at 100V, it ensures consistent and dependable performance across four independent zones.
Constructed within a sturdy 19-inch, 2U steel chassis, the CAP448 is designed for durability and seamless integration into standard rack setups. The front panel features an AC power switch accompanied by a blue power indicator LED and channel operation indicator LEDs, providing clear visual feedback. Each channel is equipped with signal presence, clip, and protection LEDs, facilitating intuitive monitoring and diagnostics. The temperature-controlled fan maintains optimal operating conditions while minimising acoustic noise.

The CAP448 delivers high-quality audio amplification with minimal distortion, ensuring clear and consistent sound across all zones. Its straightforward design, featuring essential controls and indicators, simplifies both installation and operation.
Q: Can the CAP448 be used to power multiple speaker zones simultaneously?
A: Yes, the CAP448 is designed to independently drive four separate zones with 100V line outputs, making it ideal for multi-room or multi-area installations.
Q: What happens if the amplifier overheats or is short-circuited?
A: The CAP448 includes advanced protection circuits that automatically engage in cases of overheating, short circuits, or DC faults to safeguard the system and connected speakers.
Q: Does the CAP448 support daisy-chaining multiple units?
A: Yes. It offers XLR link-through connectors for each channel, allowing seamless expansion with additional amplifiers.
Q: Is it suitable for continuous use in commercial environments?
A: Yes, its efficient Class-D design, robust chassis, and fan-controlled cooling make it a dependable solution for 24/7 operation.
Q: Can I use the CAP448 with low impedance (e.g., 8-ohm) speakers?
A: The CAP448 is optimised for 100V line systems. For low-impedance speakers, alternative models from AUDAC's amplifier range should be considered.
