Two, product configuration introduction:
1. Imported independent DSP audio decoding chip, high and low sound adjustment. Support MP3/WMA/AAC/AAC+/ALAC/FLAC/APE/WAV and other formats lossless playback, support FLAC and other lossless audio decoding. Sampling rate up to 32bit /192K. Gentle and exquisite timbre, strong sound field, full of strength, detail performance is very excellent, let you enjoy the master level music feast.
2. Built-in high-speed transmission Bluetooth module, support Bluetooth 5.0 protocol, transmission up to 24-bit/48KHZ, let you enjoy the wireless experience of non-destructive sound quality fun
3. Independent DAC decoder. High performance audio DAC CHIP ES9023 from ES company is adopted. This is the industry's leading SABRE digital-to-analog conversion technology, sampling rate up to 192KHZ/24bit more exquisite sound, high frequency performance is clear, strong low frequency performance. The ES9023 uses a proprietary Hyperstream architecture and time-domain jitter cancellation technology to achieve record-level sound quality with a dynamic range of up to 112dB
4. The front drive adopts two imported NE5532 op amp as differential input. Power bandwidth: 140KHZ, conversion rate up to 9V/US, it is a high performance low noise operational amplifier, more drive ability, highlights better low noise performance. The tone color is full and transparent.
5. NE5532 is a perfect combination with TPA3251. Push the 150Wx2 speakers to perform most vividly. The TPA3251 uses a high-end feedback design and unique high-speed gate drive error correction (PurePath Ultra-HD) technology to deliver ultra-low audio distortion and superior sound quality, with class D technology to achieve unmatched sound quality. When the horn is connected to 4-ohm load power up to 2x175W, output; When the horn is connected to 3-ohm load power up to 2x220W,D output; The amplifier's efficiency is up to percent 90. That's a high standard.
6. After the output of imported supplement red ring inductor and Germany imported WIMA684/250V correction supplement capacitor WA90 can be perfect.
7.U section double microphone design, professional tuning, high fidelity reduction technology, continuous frequency, no noise, anti-interference, anti-noise. Dual frequency AC enhanced receiving antenna, stable receiving, receiving distance up to 50 meters
