LM1875 Amplifier 30W*2 Bluetooth 5.0 Amplifier Amp 2-Channel Assembled For 3-6.5" Speakers

Features:
- LM1875 chip meet various HiFi needs. The sound overshadows that of digital power amp and features fullness and warmer sound quality.
- Adopting optimized circuit, LM1875 circuit features wide frequency band, fine sound quality and stable midpoint.
- Output Power: 30W*2
- Compatible Speakers: 3-6.5"
- High-End Appearance: Panel and shell are made of aluminum alloy with words processed by laser engraving. It is not easy to get rusty or out of shape.
- Powerful Power Reserve: A-core non-break point type transformer ensures lower noise and quiet ambience and layering. 2pcs HiFi audio capacitors are designed for speakers, featuring fine layering and excellent low-frequency performance.
- Bluetooth 5.0: Ensures stable, high-speed connection and further transmission distance, consuming less power.
- Easy Connection: Connect to your cellphones, desktop PC, tablet PC, with lossless transmission and CD-level sound quality.
- Multiple Protections:
  DC Protection System: Automatically detect the internal circuit condition of the machine, automatically disconnect the circuit and your speaker to ensure that the speaker is always working in a safe state.
  Anti-Shock Delay System: Prevent speaker from being impacted at the moment of power-on, and remove chirping sound generated by the power-on.
  Over-Temperature Protection System: When temperature exceeds the safe range, it can automatically reduce current and output to protect the whole machine.
- Quality Guaranteed: In the design and testing process, the amplifier has been tested and calibrated many times, ensuring the machine's indexity and consistency.
- High-End DAC Chip: It is a 24-bit stereo audio DAC chip, with a dynamic range of 112dB, distortion of -93db, and direct output of 2.1V RMS audio voltage. Not fuzzy at high frequencies, powerful low-frequency performance. With advanced PCM5102 decoding chip, output enables outstanding high- and low-frequency extension.

Sound Characteristics:
- Low Frequency: Powerful low-frequency performance, flexibility, good density
- Intermediate Frequency: Human voice is round, natural, fine
- High Frequency: Good extension, rich overtone, transparent sound. Not fuzzy at all.
- Dynamics: Clear layering, like the feeling of being at the scene
- Treble, Middle & Bass Sound: Warm and pure

High-End Components:
- The core of LM1875 board uses QCC3008 chip, which supports for A2DP, AVRCP, HFP, AAC, I2S, etc. 16M SPI FLASH memory chip is used. It supports for APTX.
- Pure copper binding posts for speakers and gold-plated RCA connectors are resistance to abrasion and oxidation.
- Japanese potentiometer features ultra-low error, good touch feeling, long service life.
- Red oxygen-free coppers are added to the output to eliminate interference clutter, purify the sound quality, and enables more natural sound.
- High quality capacitors. The sound of quality capacitors are transparent and clear. Low-frequency sound is solid. Intermediate-frequency sound is powerful, with clean sound background and good layering. High-frequency sound is mellow and highly analytical.
- British capacitors enables sweet sound and fine layering.
- Japanese 25A rectifier bridge, low internal resistance, fast speed, which is very helpful for low frequency.
