The audio amplifier card deploys a state-of-the-art, Class-D digital audio power amplifier. It has very low power dissipation, generates minimal heat, and enhances battery life.

EMI is minimized through spread-spectrum and de-phase control techniques providing for optimum integration with diving systems.
