The DATEQ DDA-48 is an extremely powerful, four-channel Class-D amplifier designed for high-demand, low-impedance (low-Z) professional sound reinforcement systems, permanent installations, and live performance applications.
Amplifier Type: Class-D design featuring a high-efficiency switching power supply (up to 95% efficiency), which significantly reduces heat output, power consumption, and rack space usage.
Massive Power Output: Delivers high power across all four independent channels for various low-impedance loads:
4 x 800 W into 8 Ω (rated RMS power)
4 x 1200 W into 4 Ω
4 x 1000 W into 2 Ω
Bridged Output: Channels can be bridged for even higher mono power:
2 x 1200 W into 8 Ω
2 x 1400 W into 4 Ω
Operation Modes: Includes a selector switch on the rear panel for configuring Stereo, Parallel, and Bridge modes.
Connectivity:
Inputs: 4 x balanced XLR connectors.
Outputs: 4 x balanced Speakon connectors.
Protection: Features complete protection circuitry for reliable operation under demanding conditions.
Form Factor: Housed in a compact 1U (1 standard unit) for efficient rack installation.
