The BA-2250 Model LDA Amplifier is specially designed for professional installations where efficiency is a relevant factor. Thanks to its class D amplification technology and its switched power supply, it achieves an energy consumption efficiency of 85%, dissipating less heat and occupying only a 19 '' rack height. The BA-2250 has two 250 W rms channels, protected against short-circuit and overload, which thanks to its flexible design, allows both high-impedance public address installations at 100V and low-impedance stereo at 8 ohms. Each channel integrates a high-pass filter and an automatic stand-by per noise door, whose operation can be activated from the rear of the equipment.
