Over the weekend, I recorded this video in which I show you how to use your Hidizs AP80 High-Resolution Music Player as a High Quality USB LDAC Bluetooth Transmitter. It’s very simple to do and for the PC, it is just a USB Audio Class 2 device. The Hidizs AP80 is in charge of getting the audio that the PC sends to it and it then uses the LDAC Bluetooth codec to encode the music and transmit it to an LDAC-compatible Bluetooth Receiver.
Watch the video below:
Do you own the Hidizs AP80? Do you use the USB DAC feature? Let me know in the comments.
Video of the Hidizs AP80 using the LDAC Bluetooth Audio Codec
Today morning, it came to my attention that there was a new firmware update for the Hidizs AP80 Digital Audio player. I downloaded and installed it, and surprise! We have LDAC support now! This means that it can be used as an LDAC bluetooth receiver and should also work as a transmitted, altough I haven’t tested this mode yet.
To test the Hidizs AP80 LDAC functionality, I tried using my phone but for some reason it doesn’t work on either the HiBy R3 nor on the AP80. This may be a bug on the Samsung Android Pie beta software, or some sort of incompatibility in HiBy OS. Since this didn’t worked, I then proceeded to use my HiBy R3 as a transmitter and the Hidizs AP80 as as receiver. I logged in into Tidal in the R3 and tested the LDAC codec. It worked! Not only it worked, but the Sample Rate was also adjusted accordingly, meaning that standard 44.1Khz Tidal tracks will be transmitted and received at that very same sample rate. I also tested playing back one of a few Tidal albums that the R3 seems to decode in MQA and the sample rate again was adjusted to 88.2Khz
Here, you can see the HiBy R3 streaming a standard album and transmitting it via LDAC to the Hidizs AP80:
For my next test, I decided to plug in my R3 to my laptop and use Foobar2000 and Tidal in WASAPI mode. This makes the Hiby R3 a USB DAC -> Bluetooth transmitter. This also worked nicely:
I now have the perfect LDAC transmitter and receiver. There’s little delay, but the sound quality is better than using the standard SBC codec. Also it’s worth noting that when I used the HiBy R3 as a USB DAC and LDAC bluetooth transmitter in WASAPI mode, the sample rate was adjusted not only in the R3 but also in the Hidizs AP80, meaning if I’m using a sample rate of 44.1Khz in the PC, the same sample rate will be used in the Hiby R3 and Hidizs AP80. This is very convenient because there will be no downsampling performed. Also, the fact that the Hidizs AP80 also supports bidirectional USB, I could attach another DAC or Amp like the Hidizs DH1000 and enjoy high quality bluetooth sound.
It comes a time when I have to update my Windows devices manually because sometimes, on my Intel Atom machines, Windows Update fails to install a Windows Insider build. I know I’m not the only one who have had this happened. One thing one can do to solve this is to go ahead and download a Windows Insider ISO and then create a bootable micro SD card, with tools like Rufus. Now, the bootable part is not important, as I’m upgrading my Windows install rather than doing a clean install.
I used an 8gb MicroSD card that I have and used Rufus on my AMD Ryzen desktop machine. I then used my Hidizs AP80 in USB Storage mode to make the microSD card appear in the PC and format and prepare the card with the ISO. Once that was ready, I used the Hidizs USB-C to Micro USB cable that came with my Hidizs DH1000 (the Hidizs AP80 also comes with this cable) to connect the USB-C port of the AP80 to the Micro USB port of the tablet. From there, I was able to go to “This PC” -> The Micro SD card and launch the Windows 10 setup to begin upgrading my tablet. It is really nice that the Hiby OS that this DAP use has different modes when it comes to USB, because you can either use it as a Storage device or as a DAC.
Here’s the image where I have my AP80 connected to my tablet:
Today, I’d like to show you some photos of the Hidizs AP80. I really enjoy this Digital Audio Player since it produces a very good sound and it’s perfect for offline playback. Also, the FM radio sometimes comes in handy to listen to local stations.
Here’s some pictures of it:
Here’s the AP80 connected to the Google USB-C to 3.5mm dongle. It works straight out of the box. Simply connect it and enjoy the music. It also allows you to control the AP80 by using the headset buttons:
In this picture, you can see the FM Radio feature of the AP80. It needs to have a headphone connected to it since it uses it as an antenna:
Finally, here you can see a size comparison between the Hidizs AP80, Hiby R3 and Hidizs DH1000, from right to left:
I hope you enjoyed the photosof this little awesome player!
