wireless amplifier with digital output

How does the wireless system work?

By connecting our wireless stereo amplifier products to your home audio system, you can wirelessly stream any of your favorite audio sources, such as popular online music media (Spotify, Amazon Music(US only now), Tidal, Deezer, Qobuz, Napster, QQ Music...etc.). Online radio stations (Internet Radio, Tune In, iHeartRadio, QQFM) local music, USB storage devices and NAS. You can also use line in mode to input the sound of your TV, Video Game, receiver or CD player. The wireless system refers to the wireless console, which means that you can stream and control your audio source wirelessly, but the output side still needs to be wired to a properly configured device. Most common output devices that amplifiers connect to are passive speakers, you can refer to this video to learn how to connect the output to your speakers. And the wireless streaming protocols we support are Wi-Fi, Bluetooth 5.0, Spotify Connect, Airplay 1, DLNA, Upnp, QQ play and so on.

What devices can I apply with?

Before you purchase audio amplifier products for your home stereo system, you need to check if there is a corresponding interface. Take the A50 wireless amp for example, the A50 has a set of RCA in (line in) ports, so if the audio equipment you want to input has RCA out (line out) ports, you can wired your audio products to our amplifier via a 1-2 RCA cable or a 2-2 RCA cable, and the A50 package contains 1-2 RCA*1 and 2-2 RCA*1. The amplifier is usually wired to passive speakers, such as Bookshelf Speakers, Ceiling Speakers and on-wall speakers. Others will connect an RCA Out (line out) to their more powerful amplifier and use it with our wireless system for better sound performance and the convenience of wireless control. Also, you can connect your current vintage audio receiver to upgrade your home audio system wirelessly.

How many zones can I connect at once?

There is no limitation and it is based on your configuration. We recommend you set up with 10 units at once. To exceed 10 units or long range with distance, we advise you to wire with Lan to make the signal more stable.

  • George review for wireless stereo amplifier

    George from US

    "Great integrated amplifier for size and price. I currently have in my office next to my desk and worktable. Am currently using it with an old iphone 7 to Edifier speakers to produce a great sound. I also have used it with old Realistic passive speakers with good results."

  • ReaganDad review for wireless stereo amplifier

    ReagansDad from US

    "I extensively researched all the streaming amps. I ended up getting seven of these for a complete home streaming audio experience. I am not an audiophile. But I like all kinds of music. Myself, my wife, and my kids couldn't be happier with these. They were extremely easy to setup. "

  • Ted review for wireless stereo amplifier

    Ted from US

    "I purchased the A50 stereo amplifier from Amazon on September 13th 2019 because of its combination of WiFi, Bluetooth AND Airplay connectivity. After 8 months of use, I am still very impressed with the Arylic A50 and would recommend it to anyone who wants the convenience of all the services, quality of music output and the small size it takes up."

Ask a Question
  • Just purchased and installed the A50 off Amazon for my uncle to turn his system into Bluetooth and to deliver better highs. But I am unable to use the RCA out, nothing comes through it to his stereo. Is there a remedy to this? Also I wanted to know if this unit is compatible with the ACPWorkbench software so I can create a crossover internally to keep the sound crisp? I have the 2.1 board and I have to say, its pretty awesome making otherwise mediocre speakers sound close to high end. Keep up the good work
    the volume is different in different mode, etc Wi-Fi and BT ...., so please check if the volume is turn down to zero in APP, and A50 is not compatible with ACPworkbench ,
    and thanks for your approval
  • Does this model have bluetooth out to connect headphones? If not, is it possible to connect headphones through the line out?
    Sorry,A50 doesn't support as active device to connect other passive device, you can purchase an RCA switch to 3.5 mm adapter
  • Does it have standby mode? I mean, you can just start listening by using the app, and don't need to press power button at the remote
    We have save energy mode. when no music playing ,amp will shut off and wifi keep on .so you can listen right away when you need.
  • What is the app name?
  • The line out volume is fixed of variable? Can I use an external power amplifier on the line-out of A50 and control the volume level with the A-50 remote control?
    the line out volume is variable, you can adjust the level by IR remote or 4STREAMAPP, don't need to add an external power amplifier to control
  • Bluetooth Distance maximum for A50 ?for the preamplificateur S10 =30 Meters ........and for Up2stream Amp V4 = 10Meters
    30 meters with  antenna
  • Is it possible to stream TV sound from one s10 connected via aux input to a Mini V3 if not what do I need to be able to stream TV to multiple devices. Do I need to add SPDIF In Board or DAC Board sorry I'm a novice any help would be appreciated
    Yes, you can ,but stream in sync to another unit will have little latency .
  • Can i connect ja amazon echo show with Alexa to my Arylic A50 , so that my echo show can stream through WiFi /Ethernet to the A50?
    you can put put echo show source to A50 line in .then you can .
  • Can I connected this from my PC as source (via Bluetooth or line in) and stream to my Bluetooth headphones? Will the mic work via Bluetooth?

    A50 Bluetooth is receiver, not sender ,so it can not do the work you asked .

    For future highend model or we may think about add it or make a optional board for this feature.

  • Hi, can I use the Line out for a powered subwoofer?
    Yes, you can .
  • Hi, is the arylic a50 powerful enough to drive my bose acoustimas 3 (2 satellite speakers and 1 passive subwoofer)?
    A50 power is 50WX2CH 4ohm and with active sub support. 
    For passive sub, you need our AMP2.1 board .
  • Can it be connected to an integrated amplifier?
    Yes, you can .A50 have line out ,it can be an line out source as well.
  • How to I select tracks from USB source?
    Via our android or ios app .
  • Hi, I have now bought the A50, to be connected with my old (and still good) Marantz stereo, and a wireless speaker, a GGMM E5. I have succeeded connecting A50 to my stereo, and both A50 and E5 to my WiFi. I can now stream music online (via 4stream app) to be played on my old stereo, also simultaneously on E5 by pairing it with the A50. Happy so far. However, after many efforts, I fail to play music from my Stereo (CD, Vinyl) to the new speaker, to be carried to other rooms. To get there, I connected my CD to A50 via line in. Then I can play the CD on the old stereo via A50 (via line in mode, so there is obviously a signal), but when pairing the new wireless speaker in multimode on 4stream, everything goes mute. The main reason I bought the A50 was to play music from my old stereo anywhere in the house via WiFi. Not working so far, so not really happy. Your support would be much appreciated.
    It's GGMM issue ,because most of brands in the market can not maintain the software ,that 's one issue other device have. 
    Sync between our device is ok, same feedback from other users.  You have 2 option .
    1. ask they modify software. 
    2. replace GGMM speaker by our amp board .
  • Does the device send music via bluetooth, too? For instance, is it possible to send music to wireless headphones via bluetooth?
    It's for home audio ,you can user your phone ,run our app ,and stream music via network to our system , no distantce limtation ,very good sound .
  • Can you use the speaker outputs and the rca preouts connected to a powered subwoofer at the same time to create a 2.1 system?
    Yes, you can use in that way .
  • I have a house boat with 5 set of Stereo speakers and a network router. When I pull away from the dock I can still connect to the network, but it does not have internet connectivity. I know I can connect via Bluetooth and control one device, but can I still connect via the network without interent and group devices?
    If there is an router there, you still can control and group,but music source would be from local ,such from your phone storage.
  • Is there an update on your new high-end model which was planned to launch in 2020?
    Yes, spec will be higher than SONOS AMP
  • Is it safe to operate the A50 without speakers connected such that I can use it as a wireless interface for larger stereo system with its own amplifier.
    Yes, A50 have pre-out as well to work as a streaming source .
  • Can the A50 be used outdoors if protected from rain, inside an enclosure?
    Sure. if you could get a protection case for it .
  • If I have 5 of these centrally located, how do I control the power to them individually to be able to power each 'zone' on/off? Is the remote control IR/RF/BT/WiFi? Do they each have unique codes/pairing etc? Is there any auto power on with input signal and off with idle time? Thanks.

    You can search some youtube video to see the details how it works .

    Our system do not power off, so users can play music right away ,regrading power ,we have auto energy saving program ,once no music playback ,only keep network running ,very low power consumption .

    All sources can be controlled by app remotely .

  • Does the unit come with the 24V DC power supply? If so what country AC plug is it?
    yes, we have all types plug , will ship according to the country customer from ,or course, you can leave a note about type of plug you need when place order.
  • Are there any plans to upgrade the A50 to Bluetooth 5.0?
    The new A50 bluetooth is Blueotooth 5.0 now .it's already available in the store.
  • Can I play music in three to four different rooms using one a50 and a four zone speaker selector?
    You need 1 units for each zones. 4 zones need 4 units.
    You can refer to the page to see how our system works:
  • How many A50 devices are required for livingroom and a bedroom to have the multiroom capability, each room will have a left snd right speaker (rooms are no more than 125 sq ft)? Can you connect a smart tv wireless to the A50? Can you play the tv in the livingroom and separate music in at the same time using one A50 device?
    One room need one amp ,one amp can wire with one pair of stereo speaker .  For TV, we recommend you use SA100 ,which has OPT in ,just swtiching to opt in source when watch TV.  All your other demand is ok .For the whole network setup ,we suggest you use LAN, which is more stable .
  • Hello, does the A50support Bluetooth aptX? Kind regards, Ralf
    No .just bluetooth 5.0 .S50 pro support aptxhd .
  • Can I add up to 8 devices as a multi room
    hi Sir, yes ,we support even more, for play same music in sync in all room ,we recommend 10~20 depending your network infracture. if do not play in sync ,no number limits .
  • I have my music stored on an external, portable Hard Drive. Can this be connected directly to the A50 through the USB Port or does this need to be connected to my computer and streamed to the A50?
    Play from HDD, recommend using NAS or PC . You can stream wirelessly from your pc via itunes to our device or from NAS by our app .
  • how many sets of headphones/ earbuds could be used at the same time with this?
    It's a receiver ,if using network for streaming ,all your phones at home installed our apps can control our device. If bluetooth ,it can only controlled by one device .
  • If my speakers require 100W then I can not use the AMP2.0 correct? What are my options for in ceiling speakers that require 100W?
    Surely ,you can use AMP2.0. Normally ,in-ceiling speaker power stated there is peak power output . AMP2.0 can regular output 50WX2CH, peak power can go to even higher. I'm sure it will already give you a big loudness :)
  • is this device also Ariplay 2 combatible?
    Airplay2 will add cost more than $100 ,so we don't have plan to add that now . our apps support multiroom control ,also easy to use .
    for PC system ,you can use itunes to multiroom control as well.
  • Ciao a me serviva per trasmettere l'uscita analogica di un microfono in una stanza remota dove c'e' un'impianto di diffusione audio analogico entrambi i luoghi sono presenti la stessa wifi. qualcosa del genere ho trovato https://www.futurashop.it/filo-diffusione-audio-su-rete-ethernet-7100-ft1185m ma mi serve che usa la mia wifi grazie
    We can do the function as your described ,but will be some delay for the micphone voice ,if you 're ok ,then you can use it .
  • Which DAC chip used for A50? If it could't specify chip, just short performance specs(eg. 32-Bit, 192kHz) would ok. And What is difference A50 and SA100 ? I know SA100 has bigger amp power and more input(optical), output(subwoofer). As for me, I prefer SA100. But, A50 is much better in terms of shape, design. Do you have further plan for SA100?
    Most of our customer may hide this kind of device in the desk .
    But if you like A50 ,it's a good for a try .

    the DAC used inside is not a famous one ,all i can tell you is it can decoding 24bit,192khz and sound quality to CD quality .
  • What is the wattage of builtin amplifier (Speaker's Out) ?
    50*50W 4ohm
    30*30W 8ohm
  • Does the unit play MQA master tracks from Tidal?
    No, our future high end model may support that. Plan to launch in 2020 .
  • Hi, is the Arylic A50 airplay 2 compatible? Regards
    No,our system only support airpay 1 .
    My advice is to use our 4stream app because airplay will compress sound quality,our app won't.
