QUESTIONS & ANSWERSAsk a Question
Здравствуйте. Будет ли подключен сервис "Yandex music" ?
Currently ,you can only play yandex music via bluetooth or airplay .
Hello, can it decode DSD files?
Most of current streaming product with multiroom can not support DSD, our future highend products will support that .
Existe a possibilidade de se usar um Display LCD 16x2 na interface GPIO para exibir status como Nivel de Volume, Graves e Agudos e entrada selecionada?
Currently ,not ,we may have future DIY product support that .
When connecting audio in and out and not streaming to other devices, how much latency will there be? For music I can deal with latency, but I wan't to use the speaker near my PC for gaming as well.
If you switch audiosource in one unit and do not restream to other unit use ,there will be no latency from line in .
Does this unit have a USB digital output or toslink output?
No .We may design an DAC and SPDIF board with highend components ,launch around May, 2020.
Can connect a fire he tablet and use Amazon music hd?
Amazon music will be supported soon ,within Jan .2020
Currently ,you can only do via bluetooth or airplay .
Can I use either iTunes or Amazon music on my iPhone and will multi room work?
Yes, all music played in our system can be restreamed to other devices from us .
Is it possible to develop a custom UI for this board? Is there an API somewhere to be accessed?
Yes, we offer OEM/ODM services . If you checck the product page, there is download catagory ,you will find API there.
What setting in the app do you use to play music from a NAS or network share on your network with flac and mp3 files available?
Firstly ,we only support NAS with DLNA function .You can enter APP>>My music>>my home sharing .
How do you convert the i2s to a digital input used on another system with digital input (like receiver with digital coax in?)
Currently ,up2stream series i2s is output . We have plan to launch A50 Pro which will comes with opt in or HDMI arc in . For up2stream diy boards, we will think about add i2s in pin in the future version .
any idea it will suppot TWS/Apt-X
Using our app,you can do stereo pair ,similar to TWS ,but better audio quality and no pair distance limitation . For aptx, pls check our S50 pro ,our highend models will support aptx HD
Hello! Is there an option to add a physical digital volume adjustment? Let's say a volume knob attached to the unit and when you turn it you see the volume update on the app. Also maybe the same for playback control? I don't want to rely on the remote. Thanks!
We will launch an board for volume ,buttons things in 2020, around April .Thanks for your suggestions. !
What is the format of the IIS signals, 16 bits and 44.1 KHz? If so, can it be changed, for example to 16 bits and 48 KHz? Thanks,.
Hi, yes you are right. It is 16 bits and 44.1 kHz, that is the standard format and can't be changed.
Up2stream Pro WiFi&Bluetooth HiFi Audio Receiver Board : Is this device capable of transmitting an audio input (analog of digital) from a tuner over the LAN-home-network to wifi-speakers ? Thank your for answering.
If you source is analog signal ,Up2stream pro can support restream to other unit in sync from us.
How well does the synchronization of the stereo pairing work? Would it be more accurate than, to say a number, about 15 microseconds? Would it be also possible to pair 2 mainspeakers and a multisub array of 2 - 5 subwoofers?
The latency is around 20micro seconds. Most of music lovers can not tell that . For subwooers , we may have 2.1 board in the future or audio receiver board with subwoofer synchronization firmware . Both product will launch around Q1 ,2020 .
when can we expect a upstream pro model with 16x2 display, IR remote and physical button (Momentary switch) and coaxial out option. This will replace my need to build network players using the raspberry pi
we will launch a new complete model mid of Dec,2019. a highend streaming preamplifier, wifi ,aptxhd ,opt out ,coax out ,line in x2 ,remote ,usb, lan ,ESS DAC, AKM ADC ,the only thing not there is display .you can wait for that .
Hi, are you going to support AirPlay 2?
Airplay2 require add MFI chipset and certification ,from our check ,it will add the cost $100+ .we have airplay1 right now ,and on pc itunes support multiroom control ,for cellhpone, you can use our app for multiroom control .
we don't see an reason to do that right now .
Could there be an update option to enable bluetooth on every boot?
Our system will remember your playback setting last time ,that means if you use bluetooth last time ,it will be bluetooth all the time and don't require to swtich in app or by remote controller.
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 remeber 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.
