Small Box Suitable Everywhere-Feiao BTA30 HiFi Bluetooth Transceiver Evaluation

Hello ~ Ladies and gentlemen, we have met again. H sauce has finally finished the papers and so on. We can finally start to share some interesting things with you again (broken thoughts: the papers are finished, and the manuscripts piled up one after another are riding on our heads again, meowed...). So today, let's take a look at today's main character-Feiao Fiio BTA30 HiFi Bluetooth Transceiver, which is suitable everywhere ~

then let's take a look at unpacking first ~

BTA30 body shell is made of high-strength aluminum alloy material, and the texture can be said to be quite good. Compared with the metal frosted texture, the body BTA30 is matched with a bright acrylic top version, and shows the brand logo and two "small silver labels" certified by dual Hi-Res Audio, which is low-key and not low-key. In terms of accessories, the instructions, warranty card, data line, RCA signal line, etc. have nothing to say, but the attached foot pad can be very humanized, with emphasis on praise ~

you can basically see it out of the box, so let's talk about the configuration and functions of BTA30 in detail ~

configuration, BTA30 is equipped with high-pass CSR8675 low-power Bluetooth chip, which supports Bluetooth 5.0, 24bit audio processing and 120MHz DSP. At the same time, BTA30 is also a desktop Bluetooth decoding/SPDIF system with an independent high-performance DSP chip, namely CT5302, which can upgrade digital audio to 192k for better listening experience. In addition, in order to give full play to the transmission performance of the CSR8675, the external gain antenna of BTA30 can achieve the effect of faster connection speed and more stable transmission. The analog part of BTA30 is specially equipped with an independent DAC chip, AKM AK4490, which supports native 384k and DSD hard solution. Compared with the DAC of Bluetooth of similar competitors, it can be said to be a qualitative improvement. The op amp part adopts OPA1662, and at the same time, a thin film capacitor is added to adjust the sound, making the high frequency part more transparent. In terms of interface, BTA30 has RCA analog output interface, optical fiber output interface, optical fiber input interface, coaxial output/input interface, Type-C USB interface.

Close-up of BTA30

function, BTA30 provides three modes and four functions, namely, Bluetooth reception (RX), Bluetooth transmission (TX), Bluetooth interface and DAC decoding. Bluetooth reception supports LDAC/aptX/aptX HD/AAC HD Bluetooth format, and LDAC can support 96k/24bit audio transmission. Bluetooth transmission supports LDAC (optical fiber/coaxial input only)/aptX HD/aptX LL/SBC Bluetooth transmission format. When BTA30 is used as pure decoding, coaxial input can support 192k/24bit and DSD64 hard decoding. Optical fiber input can support 96k/24bit;USB input can support 48k/16bit. For the first time, BTA30 has added the volume adjustment method of professional audio products to desktop Bluetooth devices. It has no partial tone (accurate control through ADC curve reconstruction), fast adjustment (analog output and digital output can be adjusted), remote control through Feiao Music APP, and fixed output amplitude can be set on Feiao Music APP

PS: Bluetooth transmission and reception support one-to-two. The volume cannot be adjusted in USB DAC mode. The indicator colors of BTA30 are different in different Bluetooth encoding formats. They are SBC blue, AAC blue, aptX LL green, aptX HD yellow, aptX purple, and LDAC white.

the hardware part is finished, then what remains is the usage scene part of BTA30. Apart from the conventional scenes of transmission and reception given by the government, such as the old stereo can be connected to BTA30 to Bluetooth stereo and the CD player can be connected to BTA30 and then to Bluetooth headset. What was the scene that made H sauce determined to start with BTA30 to solve the problem? Let me tell you ~

H sauce thinks the best "posture"

scene: a certain audio Bluetooth protocol is low, so Bluetooth cannot be automatically connected back. in addition, the sound quality under Bluetooth connection is obviously worse than that of wired input (3.5 single-ended/optical fiber) and in-machine playback.

solution: connecting BTA30 can solve the problem of automatic connection. in addition, mobile phones and other devices can be connected to BTA30 through bluetooth and input to a certain audio through optical fiber, which can improve sound quality and even increase frequency.

: according to the solution ideas to solve the above existing problems, at the same time, because the audio also has a USB data interface, after trying, it is found that BTA30 can be directly supplied with power through this interface, and then the function of automatically turning on the audio BTA30 and connecting the mobile phone can be realized by setting the car mode through Feiao APP.

summary: solving the problem of common scene restrictions can also simplify the operation steps and perfect ~

So on the whole, no matter how perfect the equipment at hand is, H sauce personally thinks that BTA30 can be skillfully integrated into it, and it can also expand more usage scenarios. There are no problems with cars and so on. However, due to the well-known AKM factory fire, AK4490 cannot be purchased. At present, this version of BTA30 has been discontinued and only a small amount of stock is flowing in the market, interested friends should hurry up and buy it to earn ~ but it seems that BTA30 Pro, the upgraded version of BTA30, is already on the way, but it is not clear when the configuration and when H sauce will be listed. In short, buy it early and enjoy it early ~

finally borrow an official sentence ~ that is, there is no reason to own BTA30, if necessary, it is also ready for you ~ then attach the official highlight summary ~
