What is the difference between Up2stream Amp Mono and Up2stream Amp V4?

Actually these two are the same DIY audio amplifier module, but we have pre-set the mode jumpers on the audio module for the consumer's convenience. For example, if you want to buy a stereo amplifier board, we have pre-set the stereo mode for you. If you want to buy a Mono amplifier board, you will get the Mono mode pre-set when you receive it. Of course, if you want to switch modes later, it's very easy, just follow the instructions in the manual to move the jumper.

What is the difference between Up2stream Amp V4 and Up2stream Amp V3?

There is a difference with hardware update, which supports more features with our ACPWorkbench Audio effect tools. Like adjust L/R balance, L/R EQ settings etc. And we add more DIY pins like I2S and DAC output, so you have more options to connect more DIY modules.

    It is located in the top menu bar: Downloader -> Save configurations to Flash.
  • Hi, I am looking for a linear Power supply. Which Amperage is the best for the Up2Stream Amp 2.0 V4 ? I would like to use a 24v DC Supply. Best Regards Moritz Pott
    12V - 8 A MAX
    26V - 4 A MAX
  • How does this compare to the a50? Is it same but without the case?
    you can refer  to the compare table in our official website
  • Does any of your devices support Airplay2 ? Or if not are you planning to release one ? Thx
    There is no airplay currently,  we have plan to do 
  • You answered:"the device will auto change to line in mode when the AUX is plugged in" So do I need to Plug it in and out or can I keep it plugged in and it will auto detect the audio signal?
    It detects the Aux by physical electrical signal ,not audio signal
  • Hi, Can I use this board for a TV with a center channel, 2 front speakers and a subwoofer? (3:1) Thanks Bruce
    sure, you can use the Xout(subwoofer) pin in the board and then connect to amplifier, and two speakers connect to the board audio output
  • Hi, is it possible to drive 4Ohm Speakers with 24V-Power Supply?
    it is possible, but don't adjust to too high volume to protect your speakers
  • Hi, how can I setup a 2 way crossover filter for stereo loudspeakers, using ampV4 and the acpworkbench (I don't need a subwoofer). I think I can make use of the multi room setup. But should I use one ampv4 for the high frequency s for both channels and one ampv4 board for low frequencies? Or can I use one ampv4 board per channel? Or is there an other way. (I think that the frequency adjustments in the acpworkbench can only be made for both channels on the ampv4 board and not seperate for each channel on the board?)
    You can have one device outputting high frequencies and one device outputting low frequencies, but they must be set up separately, via acpworkbench
  • Hello, I want to connect a tv to line in/opt. Can it switch automatically to that input when audio is detected? And if I start streaming from spotify will it automatically switch over to network?
          the device will auto change to line in mode when the AUX is plugged in, but optical needs you to operate manually, and if you stream music form Spotify, the mode will change to Wi-Fi mode automagically 
    with best regards

Are there plans for a slightly more powerful amp, maybe 2x 75W to give those that will use 8ohm speakers a little more head room? How is volume controlled when the Aux In is used? Is it always controlled by the app? (i will try a record play connected to a pre-amp, then that will be connected to your amp, just trying to figure out where I will get volume control for when I play records) How do you change inputs without the remote? Primarily I'd like to know how to select the aux input when I start playing a record. Thank you,

    Yes, have plan for bigger power amp and new streaming services. 

    Line in and all other sources can be swtich via our remote controller or app .same for volume control 

  • Can you program the name of the Bluetooth connection that shows up during pairing?
    For MASS order ,we can make the firmware with the bluetooth customer want .
  • Is there any chance to access the EQ settings for permanent adjustment including all sources? I know CSR chips are capable of basic DSP stuff like Compressor, EQ, etc.. Would be great, since it is way more complex to do it with passive components. If not, is there any solution where you can get a proper DSP (for example ADAU1701) inbetween the preamp unit and the Amp itself?
    We have an MCU on board, which includes DSP there .On app and remote controller, you can adjust EQ setting for all sources. You may check if it is enough for you .For ADAU1701,we may used it on future productcs .
  • Is it possible to use the Amp without the APP? Pair the Bluetooth device etc.
    For 1st time setup ,app is required ,after that ,if you don't want to use app ,you can use bluetooth ,airplay ,DLNA or remote controller ,which is not required to use with our app .
  • Is there a particular enclosure you would recommend for this board?
    You can choose the material that won't interfere with the signal.
  • I'm wanting to use 3-6 of these, each with a hardwired ethernet connection to my router/LAN, to create a multiroom system that is controlled from iPhone / iPad that connects to the network by WIFI. Spotify / Pandora / Amazon / similar streaming services will primarily be used, but will also hook one up to an existing stereo receiver (line in, line out connections) to have the ability to push legacy media (LP's, CD's, etc.) through the system. Doable? Also, what power supply do you recommend for this unit?
    It sound like a smart and mature idea. Luckily ,our system fit all demands well. 
    For receiver, i recommend you our S50 Pro .
    For power ,you may use our power supply or you can check if some in-wall central power suitable or not  ,such as meanwell .
    All our amp need is DC from 12-21V .
  • Is there any integration with Alexa to turn streams off or automatically play based on voice command?
    no .we would suggest you use our remote ,i think it's even easier than alexa ,which still need to do by several step and wait for around 30secs . our system is more designed to use with apps ,you can browser music and find the music easily .and you can also preset the content ,click one button to play the playlist you want .
  • Can you buy a larger power supply and share it amount a couple of the amps? If you get a 15 amp supply could it support 3 boards shared?
    if there is any central power ,can generate multiple 15V power suppply ,then you can make this work .we have customer project ,installed 20 pcs in a case .
  • Hi, Is this board capable to play the stream from rj45 interface(if this is connected în the same LAN with the audio server) ? Thank you!
    Sure. that's why RJ45 is there .you can also call our system network audio streaming system .
  • ís the 4-pins speak-out plug included in the package? if not, how to order it?
    Yes, it's included .You can use it right away when you get it ,if you have right power adapter.
  • What should be the current value in the DC power adapter ?
  • I'm wanting to setup a multi-room soundsystem using speakers I already have that's sourced from a pc and router. Can I connect this board to my network without using a phone app?
    Yes. it support bluetooth ,dlna ,airplay .all of these do not require our app to work with ,except for the 1st setup . For pc, you can use bluetooth or itunes 's airplay or dlna streaming to our system . or footbar is another option .

  • hi, i am planning to use this amp for in ceiling installation and thus i will not be able to turn power on and off everytime i start or quit listening to music. has the amp the ability to notice when the mobile app trys to connect to the amp and then switch power on or off? i can imagine that this problem could be easy solved via the remote control for ONE amp, but i will have around 6 amps in my house's ceilings because i wanna do multiroom. do i have to switch power on for every single amp via its remote control then?
    Our amp has power saving technology ,when there is no music playback ,it will go to power saving automatically and very low power consumption ,only keep the wifi running .When music coming back ,all system will come back right away .So you don't need to worry the power consumption and turn them off and in this way ,you can enojoy music rightaway everytime you play something .
  • Is it possible to set this board up as mono out? I want to build an active speaker where the tweeter i driven by one chanel and the woofer by the other.
    We will design MONO products in the future. It should launch Q1,2020.
  • What Amp/Chip does this use?
    This one using TI3116 works with our DSP together.  amp1.0 using STA326.
  • Hello there, Your products seems ideal for lots of projects. The earlier question was answered my half question. I hope if you make your amp board with 2.1 (subwoofer) speaker out would be more ideal for lots of projects. What is your solution for that now. Please. Thank you.
    Current Up2stream amp 2.0 board got line pin on the board, but required a little hardware DIY skill to use it .It can be used with active subwoofer.  For passive amp support ,we will have future model support that around beginning of 2020. 

  • Do you have an available remote control?
    Yes, Up2Stream Amp 2.0 and A50 both support remote controller . For board product ,remote is only available in pacakge price .
  • Does it have a volume knob? Or can you add one?
    Our system support remote controller and app controller .so we don't have volume knob.
  • Hello. Do you have a mounting plate for this amp board? It would be very difficult to install it in DIY project.
    We may launch plate amp in 2020. Currently ,you can try with some of small items firstly :)
  • The Up2Stream Amp 2.0 is nice product! Keep the high end specs, and this module will sell very well. Does the Bluetooth 5.0 possibly have CSR9675 decoding for HD audio? Thanks very kindly, Perry
    we will have complete model with those features soon !
  • Does the multiroom and stereo left/right pairing stay presistent in blueooth mode? My idea is, once I configure my home setup over wifi and connect to one up2stream module over BT will the other modules in other rooms also play and stay in sync or does that feature only work in wifi mode?
    Yes, all music played in our system can be restream to other unit , even in stereo pair mode.
  • Can I purchase all the multi-pin cables from you and at what cost? These are a real pain to find. Thank you.
    yes. we will list the pin cables soon ,those cable normally 1-2 dollars per pcs .
  • Can I purchase the 4-pin line-out from you to drive my subwoofer amplifier in parallel to this amp (driving the mid & tweeters), and at what cost? Thanks kindly.
    If you see our line out pin and know how to use it ,and your subwoofer with filter function ,then it will work .
  • Can it airplay peer to peer like in apple tv without a need for wifi router. I wish to use it in car.
    Yes, our system need a router to work with ,but the router without internet is ok to do airplay .
  • Hi, does this amp sync for multiroom over airplay with appletv or other airplay products? Thx.
    yes .any source our system is playing can be re streamed to other unit in sync
  • multiroom -how many rooms speckers connected with this amplifier
    We have no limit about multiroom connection numbers ,but for play in sync ,we suggest at most 10 rooms
  • Hello, I am interested in building a portable speaker, I have 2 bass of 40w, 2 medium of 20w and 2 twetter of 15w, it is possible to connect everything to the board
    Yes, you can set up them together and our power  output is 50W*2
  • Hello I bought the amplifier without the DC power adapter can I used any DC power adapter with 24 volt? any recommendation? Thank you.
    Yes, 12-26V is fine .
  • I want to build a 2.1 audio system for my deck. I have two sets of speakers and a subwoofer. I've read that timing is everything, and I'm looking for a DIY build where I can control everything digitally. I want to experiment with the 'crossover' frequency between the speakers and the subwoofer (80-100Hz has been recommended). Is this something I can do with your components? If so, what do I need?
    you can try up2stream amp board with line out ,not 2.0 version .
    speaker out connect to your 2.0 stereo system ,and line out to your subwoofer.

Upstream Amp 2.0

I just got it , connect it with my KEF LS50 speakers and works fine with my DLNA server , Tidal , Blutooth . The app is fast and user friendly . I connected it with 12 V 4 A adapter and the volume is a little bit lower , but tomorrow will buy 24-26 V 5 A power supply. Ideal for average user. It is not high end , but it is really good device. I'm very satisfied.

Amp V4

habe den ersten V4 bekommen und bereits verbaut. Einiges ist anscheinend noch verbessert worden gegenüber dem V3. Man kann das Volume jetzt links und rechts trennen. Ich finde, dass der Klang minimal strukturierter ist, was vielleicht auch nur Einbildung ist, oder an meiner Lösung liegt, dass ich nicht den verbauten Lautsprecheranschluss verwendet habe, sondern Polklemmen, also Bananenbuchsen verbaut habe. Ich würde gerne Fotos hochladen, wie ich das gemacht habe, aber das geht anscheinend nicht. Bin wieder sehr zufrieden mit dem Amp V4 und kann ihn nur empfehlen.

Good fee. There is where to develop, you can add a good DAC and a body... By the sound I can say only one thing-it sounds at the level of inexpensive external sound cards (compared to Creative Sound Blaster omni Surround 5.1).
