The DATEQ DA-240 is a single-channel, high-efficiency Class-D power amplifier, designed for commercial audio installations where a single, powerful output is required for Public Address (PA) or Hi-Fi systems. It is housed in a compact 1U (1 standard unit) 19-inch rack format.
Amplifier Type: Class-D with a switching power supply, providing high efficiency (up to 85%), lower power consumption, reduced heat, and an extended lifespan.
Channels & Power: 1 channel, delivering a rated power output of 240 W RMS.
Speaker Output Versatility: Offers flexible output for both high-impedance 100 V line speaker systems and low-impedance 8 Ω systems.
Standby Mode: Features an automatic standby function, which engages after one minute of no signal detection and instantly wakes up when audio is detected at the input.
Control: Balanced input via Phoenix connectors and dedicated gain control.
Filtering: Includes built-in high-pass filters that can be enabled or disabled via dip switches.
Protection: Comprehensive protection features, including safeguards against peak, short-circuit, overload, high temperature, and DC faults.
Power Supply: Supports dual power inputs: AC (110–230 V) or DC (24 V).
