Hi,
My Android head unit has 2 Front channels RCA output only. I'd like to bypass the onboard AMP ( AC7315 I presume ) to drive an external 4-channels unit. I do not want to use an adapter to convert the internal AMP output to low level signals, so i was wondering if solder two shielded cables on the rear channels input pins of the AC7315 integrated circuit could give me the missing 2 rear RCA output.
Any idea/suggestions?
Thnx.

As the heads preferis units with connectors and then rca, rca wires or rca female directly embedded in the back ? I'm much of caraudio and gives me more security and also think give them more quality embedded back and not through such dubious connectors.
PS: I feel the language , but is a translation of google because I am Spanish .
Hi all,
I'm looking for a way to use my earphones with 3.5mm audio jack via the micro USB port. Ideally, without carrying around a bulky separate amp. I bought a small micro USB to 3.5mm jack cable but it doesn't do anything straight out the box.
I don't know if i just need some sort of software to get the cable I've already bought working, or if I need some other sort of hardware.
Reason for all of this - I managed to break my 3.5mm audio output (plugged it in to a cheap ebay car audio unit and have blown something). I have wireless earphones....but just don't like them as much as my original wired ones!!!!
Hopefully someone can help me out!!
Cheers
You will NEED external DAC and AMP.
Micro usb can only output digital signal.

You need a USB DAC. There a quite a few like FiiO Q1, AudioQuest Drangonfly, Oppo HA2-SE, Chord Mojo etc. Money is the limit
By itself micro USB does not transmit sound, it transmits a digital signal, you will need an additional USB DAC
Get a quality Bluetooth receiver. Here's a great one with apt-x low latency which is crucial for video.

PX6 MTCE CHS CANBUS TXD RXD WIRE
4GB 64GB
I have unit with two wires which I am not sure what to do with?
1- CABUS TXD / IR-IN
2- CABUS RXC
what is the function of these wires and how to use?
In addition, i have additional port for front and reverse camera which reads
1- Rear Camera Power
2- Front Camera Power
3- Front Camera In
4- GND
so i am right assuming that I can directly give 12v power from wire number 1? but I have to use the trigger cable (pink reverse no-20 in wiring diagram) to be plugged in separately into the reverse parking trigger in the canbus already fitted for aftermarket stereo, MOST Fiber/Amp Bypass!
Did you figure this out?

The txd and rxd are the wire for transfer data and receive data from the can system of the car. If your car does not have any original wires to connect them with, then you might need a canbus or you can try to directly connect them to your ODB connector for your car, it is normally below your steering wheel.
Hi,the digital audio output in both my Xiaomi Android tv & DVB-S set top box are coaxial. The DAC has only one coaxial input & one optical/toslink input.There is a switch to select either coaxial or optical.The optical input slot now has the blu ray player optical cable connected.
Is there a way to connect both coaxial outputs to this single coaxcial input in DAC ,preferably activating one coaxial spdif coaxial cable (with a 2 way switch) at any one time.
I came up with an idea but uncertain whether it will work.wire up Rca jack socket connectors with a RG 59 or RG 6 coaxial cable & connect a 2 way switch in between the two spdif out signal.The other end connects to an Rca plug.Its just like a Y cable but with a two way switch.
Do you think it is the right way or is it risky? Can the DAC be modified to add a Coaxial input.I don't want to damage the Tv.
If you guys have any other better solution ,please tell me .Thank you.

Is it possible to output audio to one of the USB cables to a DAC?
Or is it just impossible to output digital signal?
