ENHANCEMENTS
• High Audio Fidelity
Ultra-low noise, wide band width amplifier circuit combined with noise suppression circuitry produces crystal clear speech. The amplifier’s Automatic Gain Control (AGC) circuit prevents audio signal distortion and enhances speaker protection and audio quality.
• Extended Battery Operation Time
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.
• Ultra-Low Electromagnetic Interference (EMI)
EMI is minimized through spread-spectrum and de-phase control techniques providing for optimum integration with diving systems.
