AUDAC PMQ240 Four-Channel Power Amplifier 4 x 240W @ 4 Ohm Class D

Four-channel Class D power amplifier delivering 4 x 240 W RMS at 4 ohms, engineered for demanding commercial audio installations. Its high efficiency and low heat dissipation make it ideal for continuous operation in restaurants, retail spaces, conference rooms, and houses of worship.

Advantages

The PMQ240 combines robust power with compact 2U rack-mount design. Forced convection cooling with a temperature-controlled fan ensures quiet, reliable performance. Comprehensive protection circuits—DC, short circuit, overheating, overload, undervoltage, and overvoltage—safeguard both amplifier and connected speakers. Balanced XLR inputs and Euroblock outputs provide professional connectivity, while the bridge function allows flexible configuration for higher power zones.

Suitable for

• Multi-zone background music systems in hospitality venues
