Overview
|
|
|
NTP-3000 is a single chip full digital audio amplifier including power stage for stereo or 2.1channel amplifier system. NTP-3000 is integrated with versatile digital audio signal processing functions, high-fidelity fully digital PWM modulator and two high power full bridge MOSFET stages. NTP-3000 receives 2channel serial audio data with sampling frequency from 8kHz to 192kHz. It delivers 2 x 30W in stereo mode or 2 x 15W + 1 x 30W in 2.1channel mode without heat sink. Combining use of built-in mixer and biquad filters can make additional preprocessing like bass management, loudness control, loudspeaker response compensation and preset parametric equalizer possible. |
