L1305 Portable 4.4 Balanced Output Headphone Amplifier TDA1305 Audio Decoder with Micro USB Cable and OTG Adapter

L1305 Portable 4.4 Balanced Output Headphone Amplifier TDA1305 Audio Decoder with Micro USB Cable and OTG Adapter

Advantages:
- Using the classic decoding chip TDA1305, the sound reflects consistent rounded style for Philips.
- CM108 with good compatibility, implements NOS mode to decoding chip, supports up to 48K PCM transmission.
- Adopting the NOS sampling method to further make the sound more natural.
- Using 8.4V lithium battery high-voltage power supply, it completely eliminates high-frequency interference caused by boost and negative pressure reversal.
- USB interface digital transmission, decoding circuit, headphone amplifier circuit, independent decoupling, wiring, etc. have been extensively optimized.
- Software decoding DSD audio.
- Battery version circuit referred to the RA1. Use four amplification circuits to form a 4.4 balanced output.
