Power amplifier LD Systems IPA 412T
LD Systems IPA 412 T is a professional four-channel power amplifier that will provide high-quality sound in any installation, be it a hotel lobby or a conference room. The 70 / 100 V outputs of the IPA 412 T installation power amplifier are equipped with torrid core transformers, and the 4 ohm outputs are completely transformerless, guaranteeing the highest possible sound quality. The DSP processor is equipped with a parametric equalizer with a library of presets, a matrix mixer, the ability to select a priority source and delay. Despite this feature set, the IPA series power amplifiers are easy to use. All the most important functions are visible via LED indicators on the front panel of the amplifier. HPF/LPF filter presets can be activated directly on the device using DIP switches. A slot on the rear panel accommodates optional expansion cards: the Ethernet card offers comprehensive configuration and control via software, while the Ethernet + Dante card also offers connectivity to a wide range of devices, allowing the IPA 412 T to be integrated into a Dante network and handle more complex applications. Scalability and future-proofing are the biggest advantages of the IPA series.
