AUDAC CAP248 2-Channel Class-D Power Amplifier 480W RMS 4 Ohm 1U Black

The AUDAC CAP248 is a professional 2-channel Class-D power amplifier designed for fixed installations and live sound applications. Delivering 2 x 480W RMS at 4 Ohm or 2 x 240W RMS at 8 Ohm, with bridged capability up to 960W at 8 Ohm, this 1U rack-mountable amplifier combines high efficiency with fanless convection cooling for silent operation. Its balanced Euroblock inputs and speaker outputs ensure reliable connectivity, while comprehensive protection circuits safeguard against DC, short circuit, overheating, overload, and limiting.

Advantages

High power density in a compact 1U form factor, fanless design for noise-sensitive environments, and robust protection features for long-term reliability. The Class-D topology ensures energy efficiency and minimal heat dissipation.

Suitable for

• Fixed installations in commercial spaces, conference rooms, and houses of worship
• Live sound reinforcement for small to medium venues
• Background music and public address systems
• Any application requiring high-quality, reliable amplification in a compact rack space
