  • TOA Digital Amplifier technology redefines the very concept of amplifiers.

    The power supply unit is the heart of the amplifier.To ensure consistently high performance and reliable operation, TOA engineers have given the DA Series a system that provides power independently to each channel. This testifies to TOA’s attitude to product development, which is always totally motivated by the desire to provide high-quality products that offer worry-free use.
