Ask a Question
  • If I start streaming to it on Spotify via Wi-FI or via Bluetooth will it switch automatically to Wi-Fi/Bluetooth, or the input mode has to be chosen manually?
    It can change to Wi-Fi mode from BT OR INPUT MODE  automatically, other situation you must switch mode manually
  • Hi, We have noticed during our tests of Up2steam Pro v3, Up2stream Amp 2.1 and Up2stream Amp V3 that in the ACPWorkench tool the Parametric EQs on the separate Channels are locked (not accessible) with the Up2steam Pro v3. There is only main Music EQ accessible. Can they be unlocked?
    The main adjustment is in the second tab, which in theory is all unlocked, of course to make sure you get the last firmware of preamplifier
  • Can I Use 'SPDIF In Board' and Volume Knob Board with Up2stream Pro V3 board ?
    Yes, they are not conflict
  • I can't activate the Spdif Out Up2stream Pro V3 with 4Stream. I connect the SpDif out with the seven pin cable but nothing happened. How could I activate the digital outputs
    The spdif out is active in default, you don't need to do more operation, you can try to only connect the spdif and VCC and GND pins to exclude the cable's problem
  • How do I use this as a standalone Bluetooth receiver without it being on a LAN?
    you can swtich all sources via app or remote controller,or button on the board .
  • Hi, the board is standard I2s out and coax out, i read it is possible to change direction in ACP. Is it possible to stick with I2S out but reverse Coax/optical board as input?
        you can concern about purchasing out SPDIF IN expansion board, and change the direction of SPDIF through ACPWORKBENCH,becuase the direction of SPDIF is IN in
    default situation
  • Can it switch a relay card via GPIO to switch off an active amplifier if no sound? can I then program it via ACPWorkbench?
    yes, you can select OUT option as the trigger to give signal to you active amplifer after setting in acpworkbench
  • I have this board and the SPDIF input add-on board, and ACP Workbench still locks out the SPDIF input when I select RX or TX. How do I get this enabled?
    you need to change the set in second tag 
  • What is the circuit to connect an encoder for the volume control to the GPIO header? How is using this header different than using the 11 pin connector volume control pins?
    because the GPIO header is reserve for diy, you can select some mode in acpworkbench  , volume knob expansion board is a one option of them ,  key pin in 11 pins connectors, you will setup the resistors  refer to the diagram
  • Tem algum display ou tela que possa ser usado no up2strem pro v3 ? Obrigado
    We will soon be releasing a 128*64 screen, which we have already done on the s50 pro +, so stay tuned!
  • I am considering purchasing the pro v3 version for a boom box retrofit to add usb, sd, bluetooth, and wifi. It seems there isn't really a way to fully control this without a WiFi connection. I would like to connect this with an arduino to enable full functionality and also integrate a screen while I'm not tethered to wifi. Will the uart api be coming soon?
    hello, the method of uart control is been  developing, the progress of the projects is over 60%
  • How can I activate the SPIDIF-IN board? I tried connecting it via the flat ribbon cable labeled "For Mini V3/Pro V3" but the Input doesn't show up in the 4Stream-App
    The default setting is for spdif out .If you need to use it as spdif in ,you need to get acpbench from us and change the definition of the I/O to spdif in ,then you can use it .
  • I have my music all stored in a QNAP server. I'm able to access the music using their QMusic app. Does this device support QMusic or can it access the folders in my QNAP server?
    We support NAS with DLNA features. you can try ,if not work , you can return to the webshop .
  • can I use the Up2Stream Pro RJ45 Ethernet cable to stream audio?
    Sure. via wifi ,lan ,bluetooth all are ok .

    you can try our spdif out board ,wire to up2stream pro .

    the micro usb can be worked as usb digital audio in . 

  • Does UP2Streem Pro work with free version of Spotify or do I need spotify premium to use UP2Streem Pro
    Spotify connect wireless streaming require spotify premium acocunt ,it's their policy .
    IF you want to use free account ,you can connect our system via airplay or bluetooth .
  • I see V3 Act as USB DAC via micro but question is - whether play on external DAC plugged via USB?

    V3 can work as USB DAC, you only need connect your PC directly to our micro usb port and play music .

    This source can be also playbacked in sync to other units .

  • Hi, how could I connect multiple boards like SPDIF IN, SPDIF OUT, DAC and volume knob all together to the same UP2Stream_Pro V3 module? Is it possible, or can I connect only one? Many thanks.
    For spdif ,you can only connect one ,due to limited GPIO ,but others are ok .
  • Hello, is there also a "mono" up2stream-device available? I'm planning to build a multiroom system in my house. In the bathroom there is only one speaker chassis (mono). Is it possible to make a "stereomix" or mono configuration with the up2stream modules? Is a single channel module planned?
    We have up2stream amp v4 planning ,which will support stereo and mono mode. You can get others firslty and mono later.
  • Do you have an API ready for UART management? Can I find out a list of commands for monitoring and control?
    Yes, http api available in our website >>download
  • Hi, Can i have 5 of them playing my music (streamin from a pc) (in different places) via ethernet and control them via some inteface from my pc? There is a small cafe chain here...
    would control by app a better option  ? app have more control . for pc, you can only playmusic via itunes .
  • How meny of UP2Streem Pro i can connect in one house I want to create 16 zone can I able to do it using this one?

    Normally ,our users will buy one amp for one room to work with one pair of in-ceiling speaker.Each room need one set of that .


  • Where are the UART connections on the Upstream Pro V3 (which pins) and what are the commands, BAUD rate etc. to control the device for example with an Arduino. Is that even possible ?
    Hi, we're now preparing a set of API for the UART interface. And you can get the feedback of the playing status, and also can send some controls to the board, like volume, next, prev, change source, etc. We'll still working on this, and hope to release in end of Oct. It would be a normal UART bus with 115200,8,n,1 and Arduino will be OK in sure.
  • I am trying to use physical buttons on Up2stream_Pro_V3. I have build a keypad using the schematic and the resistor values in the manual. The buttons Num1 and Num2 both trigger Preset 2, Button Num3 triggers Preset 4 and Num4 does not work at all. Are the resistor values in the manual correct? Are they very critical or should regular 5% resistors work?
    Hi, we've made a mistake in the manual that, there's an 10K pull-up resistor on board already. So please make sure to remove it on the board you make, and also the voltage tolerance range is a bit small in the firmware. We'll extend it in the new firmware which would be released soon. For now, you may try change another resistor or wait for the new firmware :-)
  • In your Q&A, you indicate: >>Can de pro v3 toggle a external relay so when the board is in standby my amp and dac board are powered off and when the pro v3 turns on the relay will witch and the amp and dac have power? Yes, it can do . if you don't know the way ,pls write an email to us ,we will aks our tech to guide you .
    Hi, we're now working on a firmware upgrading, and hope to release in the end of Oct. It will have a feature to set the PIN functions with tool ACPWorkbench. So you can assign a not used PIN for the output trigger. And it will output high level when have sound output, and turn to low level after 1 minuts no sound.
  • is there a way to use as pre amp 2.1 hpf and lpf for a sub?
    We do have a ACP tool to set separated EQ on each channel (Left and Right), but we do not have a standalone output for the sub. Will consider to add this in future hardware.
  • Is there an API to play a saved Preset List from eg Spotify?
    After you set the playlist to presets on Up2Stream boards, then you can play with HTTPAPI: http://DEVICE_IP/httpapi.asp?command=IOSimuKeyIn:002, this will play the preset #2, and param ranges from 001 to 010, stands for the 10 presets.
  • Can I send the Line-in signal captured by a Up2stream Pro to other Up2stream devices? Like a wireless signal transmitter.
    Yes. you can do that via our app .
  • Can you give this a fixed IP address?
    No, it currently does not support fixed IP address. To make it static, you have to bind the IP and MAC of device on router.
  • I am a little confused about the USB socket. It is listed as an input but some of the answers I f the Q&A section suggest it can also be used as a digital output to connect to an external dac, Is this true? If not, do you sell, or plan to sell, a product that allows you to output 192khz digital output to allow connection with a separate DAC?

    USB HOST is for playing music in the storage.

  • Hello. Can i use this product (Up2stream Pro) to drive two mono amplifers, one connected to a woofer HP and the other to a tweeter HP, both in the same closed box ? Can i access to the multiband EQ parameters in the chipsets ? If yes, how many bands can we control ? Can i route the left or the right channels to both outputs ? Is there a crossover control between the outputs ? May be i need to use the IIS output and do this in a IIS input stereo amplifer (with crossover and EQ parameters features ? Thanks a lot for your reply. Jean-Pierre
    we have no interface for user to access the internal 5 bands EQ of chipset AP8064. So your last solution is the better choice, you can use Pro board as a music source, and connect the i2s output to a digital amplifier and then adjust the CF and EQ settings of amp chip to meet your requirement.
  • Hello, I’m planning on using a number of these on a large outdoor mesh network. What is the maximum number of units I can have...just looking to use one zone. Also do you know of anyway to stream a live microphone to use it like a wireless PA system
    We have no limit on the connected numbers right now . For sync playback ,we recommend 10 . We will develop model with microphone on the future model. Thanks for your advice. 
  • Two questions. Can this act as an access point when in a remote (no wifi) location? If yes, can you still stream music if your phone has service? What chipset is being used for the DAC? Burr Brown? Wolfson? AKM? Other?
    Our device or system have to work with Router or hotspot ,which can be without internet access. 
    DAC used is not a famous one ,but still sound good and with 24bit,1982khz decoding . We will have highend complete model in the future using ESS or AKM DAC. 

  • How well does TWS work with these boards? (also known as multicast or stereo sync) Do they retain sync after power loss, or does that have to be redone each time they lose power? I'm building two completely separate, portable, bluetooth speakers that will receive and play synchronized audio from a bluetooth source. One board for the left channel speaker, the other board for the right channel speaker - both as completely separate units, usually placed about 3m from each other. (I already have amplifier boards, power supplies and batteries of my own.)
    We do stereo pair by wifi ,but the music source can be all we supported ,such as wifi,blutooth ,airplay,spotify,dlna,line in even opt in if our unit supported. our system will remember stereo pair setting ,so if power on again ,if will do it automatically .
  • When you link multiple Up2Stream Pros, can you disable the wifi and bluetooth of the other devices? Also, is it possible to rename the bluetooth device? instead of having it show 'Upstream_D8B3'?
    WiFi will be hidden after connected ,or disabled if using LAN  bluetooth is off ,it broadcast and work when you swtich to BT model when you swtic that inside app . In the app ,you can change the room name, bluetooth name can not be changed right now .
  • Hi, I want to connect my Onkyo AV receiver to wireless rear surround speakers. Can I use these devices?
    IF you receiver got line in port ,then it will work .Imagine our device is a CD player,which already included thousands of CDs and you can control everything by apps !
  • Hi, Does the Up2Stream Pro also supports Stereo Pairing (via Wi-Fi)? Kind regards, Lode
    Yes, our all products support 2.1 stereo pair system
  • Hi, is it support Pioneer FlareConnect™?
    Currently ,it only support dlna ,airplay ,spotify connect or stream via our app .
  • Hi, Can this module also stream the line-input to other Up2Stream modules in a multiroom setup?
    Yes , line in ,usb ,bluetooth all can restream to other up2stream unit ,all our products support that .
  • Hi I want to build a media streamer for hifi (I have a NAD M51 DAC and I use Spotify). The Up2stream Pro WiFi&Bluetooth HiFi Audio Receiver Board seems like a good start but I wonder if the module is sufficient to feed a good DAC for high-end audio playback? If so, what does it take in terms of other components i.e transformers, connections, etc.?
    Yes, the biggest advantage for wifi streaming is fit the hifi demand . The components will make a little difference. Everybody have different definition about that. 
    I recommend you buy a basic model to try ,to feel yourself.
  • Hello, is it possible to controle the on_off, mute and volume with a API (smart home system) ?
    we have api for that ,except control on_off, for our amp model, we have auto energy saving technology ,when no music, then amp shut off .
  • Hello, what are the bluetooth codecs supported? SBC, APT-X, APT-X HD, LDAC?

    It's middle end bluetooth 5.0 with good sound performance. 
    but not CSR model ,which is not with those high-res codec .
    To play high-res files, absolutely,we recommend you use our app to stream via app .which is even better than APTXHD. 
    For future highend model ,we may use APTX HD chipset ,but price would be different .
    old models still can group with future new models.

Excellent value!

I bought this as a second Airplay source to my multi zone audio. I love that the volume can be controlled using whichever device is playing, without need for the app! Though it occasionally hiccups, I’m very satisfied and want to buy another one.

Thank you! Excellent device. The network has reviews and measurements of this board. Configured using the 4 stream application. Internet radio plays perfectly. With USB music reads, only I did not like how the device sorts files on a USB flash drive. I recommend!
