  • 2.1 amplifier review from Stefan

    Stefan from DE

    "I already own an amplifier from Arylic (Amp v3). This allows me to integrate the subwoofer into my sound system via Wlan (wireless!). The whole thing is called Multiroom-Mode and works excellent and reliable."

Ask a Question
  • I have 2 x 2.1 amps and a A50 connected together via Eero mesh WiFi router. All of the amplifiers are as close as I can make them to the WiFi antennae however they are connected to different mesh nodes. Your App says I have 2-5% signal and I hear is occasional cracking which is ridiculous. I am trying to replace a Sonos system and dearly hope you system will work. Am I to understand that your system does not work with mesh wifi systems?
    To explain for the multiroom mode of the device. There's 2 modes to create multiroom.
    1, router mode, and the audio data will go through the router from master to slave, and this mode will be used only when both of the devices are connected with ethernet.
    2, direct mode, the master device will create an access point, and the client device will connect directly to this AP of  master, so if the 2 devices are not close enough, it would be a problem. And this mode is used to support to connect as much clients to the master as possible. If going through the router in wireless, the network would be badly affected as 2.4G WIFI bandwidth is not good enough for the audio streaming.
    For your condition, if you can connect both device to ethernet, then it should be OK.
    And some progress for your reference, we're now pushing the module vendor to develop a way of always creating the multiroom with router mode, no matter connected with ethernet or wifi, and by using audio compressing technology to save the bandwidth. This will compensate some audio qualities, not too bad and it will keep about 128Kbps MP3 quality, and should be enough, as the multiroom mode is always used for the background music. It's in progress, but not so quickly to release.
  • What is the type of the DSP used? I like to know the DSP capabilities. What filter types are available and what is the tuning range of f0, gain and Q of each filter that can be set? Most likely the DSP manufacturer also has this listed in the datasheet.
    MVSILICON bp1064,it has 10 filters ,fc's range is 24-24000, gain is -12 - 12dB,the Q  range is 0-30
  • I would use 2.1 Amp to drive TV soundbar. Is there any way to to connect TV and Amp 2.1 via Optical cable? Do you provide control plate which can be mounted on the back of soundbar and allows confortable connection?
    You can use our spdif out accessory board, and use acpworkbench to change the default spdif input into spdif output, because our amp board is in the default spdif in mode
  • Up2stream Amp 2.1 doesn't come with Wifi antena? the only way to conect the board is through ethernet? why just come with 1 antena (I assume is the bluetooh antena) and not with 2 antes like other boards ?
    Yes, 2.1 just comes with wifi internal antenna ,for bluetooth ,we used on board antenna. also kept iPEX connector for external antenna extension ,but need to buy optional .
  • If I understand correctly the 2 (out of 2.1) stereo channels have a high pas filter to filter out low frequency, can this filter be turned of if I don't have a subwoofer connected? Would this be possible with the ACPWorkbench Audio Effect Tool software?
    You can make it by acpbenchwork .
  • Boa Noite adquirimos a placa Up2stream mais ou menos uns 6 meses e somente hoje tivemos a oportunidade de testar ... ok colocamos a placa para tocar sem a atualização do Firmiware ... tocou de maneira linda ... realmente uma placa diferenciada som muito fluido ... e após atualizar o firmware para a última versão , percebemos uma piora na qualidade , como uma compressão de sinal e o som que era lindo e que nos encantou perdeu a magia ... existe como voltar com o firmware antigo ?
    Sir, we already fix this issue by firmware update. pls try .
  • Hallo Kann ich einen Subwoofer ohne Frequenzweiche betreiben? Kann ich die Übernahme Frequenz an den Drehreglern einstellen?
    no, with the rotary knob you can't. But with acpworkbench you can set any parameter eq on each channel
  • Is it possible to change the volume with any dlna App and also with the volume knopp? I'm able to setup the startup volume? Markus
    Volume of this board support control from app, dlan app ,remote controller or volume knob on the board.
  • Would it be possible to move the crossover for the sub a bit higher than 200Hz? Could it be done in the ACPWorkbench?
    with acpworkbench, yes it is possible.
  • I´ve read a lot about upcoming features, but i am not shure what is functioning right now and what not... I´m planning to Make a 3way Setup with the 3channels of the amp and then i want to pair it to a stereo Pair wirelessly and maybe use it with cabels... so there is a buch of questions... Can i edit the Channels with the software as a crossover so one amp only takes on input channel and split these to the Speakers as crossover? with EQ and stuff? Like a DSP? How am i able to pair 2 amps? Could that be permanent? Do i have to use the app for that - all the time? i want to use airplay and spotify connect. would that be possible in stereo pair mode? - As i read i think atm not everything ist working right? will there be an update on these units so i can buy and the update firmware - when would that be possible? If you plan a new AMP when will it come out to realize such a system? Sorry fort all that questions at once...
    yes, with amp2.1 and acpworkbench, you can use it to drive your 3 way speaker, you can set to output mode with left/right/stereo, and apply eq on each channel. And you can use multi room function to pair 2 device into a stereo system, you need to group it with app first and the they will work in group in the future, even after next power on. The current system support this features already.
  • I would like to control player with home automation software (Home Assistant). Does the device have a network (wired or WiFi) available API to allow control without a phone?
    Yes, network control API is available in our download page in our website.
  • Hi Folks, it lists micro USB as an input from a computer. What type of micro USB this is 2 or 3? Need to connect iMac to this - therefore USB A to Micro USB B version 2? Correct? When will you come up with ACPWorkbench for IOS/Mac?
    USB 2.0 type A to Micro B, no IOS/MAC version ACPWorkbench in plan yet .
  • Hello, is it possible to connect two amps without having wlan? I want to build two speakers for outdoor parties.
    You can use LAN
  • Hi, how does the board handle input switching between analogue in, blutooth and wi fi? Is there any kind of input sensing?
    Our app and remote control have all the option there ,you can swtich easily .
  • Do you consider to provide to up2stream users the functionality of adding manually the speakers(by providing the IP address) ? In case of a routed network, the speakers search fails. Currently, the only way of controlling the playback status is via http, using a complicated URL.
    Sir, we're working on it :)
  • peut on utiliser le arylic up2stream amp 2X50 +100 en mode 2.0 avec juste une seule paire d'enceintes et avoir toute la bande passante? Merci.
    Yes, with the ACP tool, you can adjust the filters manually.
  • Does this support airplay 2?
    No, It just support airplay1,but with our app ,you can do multirooom and multizone control ,that means you can play differet music from different source to different room ,or play same music in sync in all room ,or you can group different room into several zone, play different music in different zone .
  • Dear. Please , the dual and Mono out has some filters : Low pass for Mono out and Hi-pass for stereo out? If yes, what is the frequency point
    Dear, the AMP2.1 board does have a high pass filter on the stereo output, and a low pass filter on mono output. the default frequency is 110Hz, and you can long press the Treble/Bass knob to adjust with 30Hz step, and ranges 50Hz to 200Hz. (Treble to increase, and Bass to decrease)
  • Is it possible to make the stereo output into dual mono? I'm planning to build a single channel active speaker.
    Yes, we 're developing this feature right now .Hope we can have it ready within this year .
  • Hi, which connector do you use for the WLAN and Bluetooth antenna?
    IPEX type
  • Hi - regarding the Up2Stream AMP2.1 - is my understanding correct in that a passive subwoofer would be okay given the AMP2.1 also has an amplifier for the subwoofer? - using an iphone, is it possible to connect to the AMP2.1 using Apple Airplay and then stream music over WiFi LAN. Or is it necessary to download and use the 4STREAM App? - can the AMP2.1 also be used without a subwoofer? Cheers, Lars

    It is a 2.1 amplifier, you can drive an stereo passive speaker and an passive subwoofer.
    You can use airplay or our app to stream your libarary .
    For first-time setup ,you need our app ,after that, if you use just airplay ,you can use without it .
    Surely ,if you don't connect a subwoofer ,it can be an 2.0 amp as well. 

  • Does the 2.1 Channel Upstream amp work with the IR Remote Control?
    Yes, all board work with our IR remote .
  • If using Digital in from a NAS Library, can the music be served to other devices like the Mini V3?
    Our device can recognize DLNA streaming ,for your NAS, we can not be sure, you may have to try .
  • Dear Support Team! What power can die 5v Output handle? And, can it be, that the + / - marking on the board is the wrong way around? Regards Christoph
    It's kept for our accessory board use, which will be on sale in Sep. The mark is wrong way ,we already fixed on new batch .
  • hello, what is the cross over frequency for the .1 amp ? can it be adjusted in ACPWORKBENCH ? How ? regards
    Long press the bass knob ,you will enter to LOW PASS filter .
  • Hello, is it possible to swap the 2,4GHz Wifi Module to a 5GHz one? Thanks
    It only require using 2.4G for set up on first time ,after that, your phone can connect to 5G to control our device .
    We will think about adding 5G on future highend model ,it will increse the cost .
    btw, sonos also just have 2.4G .
  • Can I use an Arduino to connect to the HTTP API via the 10/100M ethernet connection to get / send parameters, while the Up2stream device still connects to the lan / internet via 2.4G wifi?
    Yes, our Arduino can works like a pc system . it should work .any device send command via our ap ,our system will do .
  • Dear all. Why is the Android only working in portrait mode? I am using a tablet, which is permanently mounted on the wall in our living room to control all wireless devices. Unfortunately the 4stream app is quite unusable in portrait mode when the tablet is mounted in landscape orientation. Will it be able to use the app also in landscape orientation in a future version?

    Currently ,not ,but will support that in future. We will also launch a tablet ,both can be used in vertical or landscape .our app will detect .

    Under developing right now .

  • Can this be used as a USB sound card? It lists the microUSB as an audio input but there is no other mention of that feature.
    Yes, it can be used in that way .we will try to check our content and update that.
  • What's the diference 2.1 vs Up2Stream amp V3, What´'s the chip amp of the 2.1. The input of the 2,1 amp chipset is digital?
    Both TI 3116 chipset .For digital in ,we will sell an SPDIF in board soon to work with it .
  • What power supply is recommended for this? do you sell them?
    You can use power supply from 12V - 24V.
    We sell a 24V 4.16A power supply, but if you want maximum output power, you will need to use a 24V 8A power supply.
    Remember, do not go over 24V or you will damage the board.
