The DATEQ DA-2120 is a stereo (2-channel), high-efficiency Class-D power amplifier, ideal for rack-mounted installations in commercial audio environments requiring moderate power for Public Address (PA) and conventional low-impedance audio systems.
Amplifier Type: Class-D design with a switching power supply, resulting in high efficiency (up to 85%), minimized heat, lower power consumption, and increased longevity.
Channels & Power: 2 independent channels, each delivering 120 W RMS.
Speaker Output Versatility: Supports both high-impedance 100 V line speaker systems and standard 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 is managed via Phoenix connectors, with individual gain control for each channel.
Filtering: Includes built-in high-pass filters that can be enabled or disabled via dip switches for system optimization.
Protection: Complete protection circuitry covering peak, short-circuit, overload, high temperature, clip, and DC faults.
Power Supply: Supports dual power inputs: AC (110–230 V) or DC (24 V).
