1. Cheap Conversor Digital-para-analógico
Two version:
8675+PCM5102A :board only or board+case
8657+AK4493:board only or board+case
support LDAC and APTX HD
LDAC supports 96KHz/24bit high quality audio up to 990kbps.
The Apt-X HD is up to 576kbps
Android 8.0 or higher system supports LDAC , the most accurate is to open the Bluetooth related settings to see which mode is supported, LDAC is supported. LDAC is not supported. Apt-X HD is generally supported.
LDAC has three modes:
1.sound quality priority mode (990kbps),
2.standard mode (660kbps),
3.connection priority mode (330kbps).
T he names of the three modes may be different on devices manufactured by different manufacturers. The sound quality priority mode allows the transmission rate to reach 990 kbps, enabling lossless playback of music. Generally, the mobile phone defaults to the priority mode, and you can set the sound quality priority mode yourself.
1.Bluetooth 5.0 8675 + PCM5102A decoding, support for LDAC and APTX HD . Real 5.0 module.
2. The PCM5102 is independently decoded, and the I2S protocol transmission is performed. It is much better than the Bluetooth playback board without decoding output. The decoding further improves the sound quality and resolution . Not a typical toy level Bluetooth audio output comparable. The signal-to-noise ratio is 112db, which directly outputs 2.1V RMS audio voltage. The high frequency is not burr, the low frequency is full, and the dive is good.
3.In order to have lower output impedance and good matching output, adopt the HIFI op amp AD823. This IC is used on the colorful classic player C4. The sound performance is clean and stable, the sound level is rich, and it has good control.
