Характеристики
tube single end ampplifier
This product supports BT5.0. Low transmission delay, support for a variety of lossless format transmission, the mostcritical is the output plus TI advanced decoding chip PCM5102, than the general toy level of the BT board regardless of
level, detail, high and low frequency extension is much better!
The product supports A2DP, AVRCP, HFP, AAC, I2S, etc., adopts 16M SPI FLASH memory chip.
The decoding part adopts the latest PCM5102A decoding core of American BB Company. It is a 24-bit stereo audio digital-to-analog conversion chip (DAC) with a dynamic range of 112dB, distortion-93db, direct output of 2.1V RMS audio voltage, high frequency without glitch. The low frequency is strong and the dive is good.
Be sure to note that the F50 tube can also be inserted into the tube seat if the tube is switched to 180 degrees. During
installation, note that the glass protruding part corresponds to the foot of the tube seat with two slots
