ntp7515D chip parameters:
1. It has 24Bit, 96KHz high-quality audio data processing and supports Hi-Res audio system. Other brand power amplifier products basically only have 48K data processing capabilities.
2. APEQ patented technology, when the frequency band is limited, other frequency bands can be independently improved to give full play to the maximum performance of the speaker (corresponding products: NTP8204, NTP8214, NTP8824).
Use ordinary chips: As the volume increases, the point with a relatively large EQ gain will easily trigger the DRC threshold, causing the volume to be unable to continue to rise. If the DRC threshold is relaxed, the part with a large gain will easily be distorted and the speaker will easily break. sound.
