BA-3 Bluetooth Decoder Bluetooth 5.0 DAC AK4493 Hifi DAC Assembled QCC3008 Supports 16Bit 48K

BA-3 Bluetooth Decoder Bluetooth 5.0 DAC AK4493 Hifi DAC Assembled QCC3008 Supports 16Bit 48K

Description:
BA-3 Bluetooth decoder is designed by a professional team for music enthusiasts. This is an entry-level HiFi decoder. Unlike conventional Bluetooth decoder, BA-3 adopts a desktop decoding architecture, not a general mobile portable architecture.

With this Bluetooth decoder, you can enjoy music easily.

Technical Highlights:
- Reasonable layout: Stagger Bluetooth reasonably to minimize interference
- Source synchronous clock technology: Bluetooth IIS data transmission lacks a clock line, it obtains the synchronization clock with the IIS signal through technical processing
- Professional power supply: Up to 4-way AC voltage inputs, and 8pcs LDOs on the board are regulated to minimize mutual interference
- Desktop HIFI dedicated decoder chip AK4493EQ: AK4493EQ is a mainstream decoder chip, which is close to AK4497 in tone, and is commonly used in professional desktop decoders of various stations
- Pure straight LPF, no coupling capacitor, direct and transparent sound
- Independent op amps for left and right channels, high separation and accurate positioning

FAQ:
Q1: Can my mobile phone be compatible with BA-3 Bluetooth 5.0?
A1: BA-3 Bluetooth module uses QCC3008, supports for APT-X (16Bit-48K) and backward compatibility. For Android 9.0 and above, it supports for APT-X, HD, LDAC (have not tested for Apple)

Q2: Will BA-3 freeze during playing?
A2: Stuttering is not generated by the Bluetooth module, but by mobile phone. WIFI, Bluetooth, and 4G in most mobile phones share antennas. When playing online music files, especially when opening for APT-X and playing files above 30M, you will find that your phone is buffering data while playing software. At this time, it is recommended that users download music file to the mobile phone before playing, so that there will be no freezes.

Q3: What is the difference between BA-3 and other Bluetooth decoders?
A3: The technical highlights of BA-3 is the important difference from other Bluetooth decoders. Here we will introduce the source synchronous clock technology. Users who know the Bluetooth module know that the IIS signal of the Bluetooth module lacks the MCK clock line. Many businesses use low-performance DA chips at the expense of sound quality due to lack of technology. Another way is to use a desktop professional DA chip with an external clock. The external clock will cause the problem of not being able to synchronize the signal.

The power supply system is a major advantage of BA-3. BA-3 uses four channels of AC input and 8 channels of LOD to supply power separately. BA-3 outperforms general Bluetooth decoding scheme that shares a 12V DC input and then divides the voltage power supply. Thanks to the power supply advantages of BA-3, LPF realizes direct coupling. Compared with general Bluetooth decoders with output coupling capacitors, BA-3 is once again leading in terms of sound transparency, details, sound field positioning, and sound dyeing.

On decoders, another device that affects the sound quality is the DA chip. Generally, Bluetooth decoding is usually a low-performance non-mainstream chip, such as PCM5102. BA-3 uses the AK4493EQ mainstream desktop DA chip, which is obviously different in nature, especially in dynamics.

Q4: How is the sound quality of BA-3?
A4: The sound quality varies with each person's system and sense of hearing. Our sense of hearing: It is with a certain resolution but not thin sound, good detail performance, direct sound without excessive modification, wide sound field, sharp dynamics, and a little air.

Q5: Is there a big difference in sound quality between BA-3 and desktop decoders?
A5: There is still a slight difference from the excellent decoding product for XMOS-AK4493. The difference lies in the black quietness of the background. The main reason is that the Bluetooth module's jitter is larger than that for XMOS.

Q6: Are there any upgrades in the future?
A6: BA-3 has basically met the listening needs of HiFi fans, and at the same time, it has also started to prepare ES version Bluetooth decoder for ES fans. We will roll out a higher level of Bluetooth decoder BA-7 which will surpass many desktop decoders.
