Support: A2+ Wireless Speakers

Questions & Answers

  • Question:

    How can such small speakers have so much clean-sounding, deep, tight bass?

    Answer:

    One of the reasons Audioengine active and passive speakers have such amazing bass in such a small package are the designs of the bass ports on each speaker. These aren’t just holes or slots in the cabinets, but specifically shaped openings with tubes designed with precise calculations. The result is incredible low end with minimal audible air turbulence. These are effectively mini-subs built into each speaker, allowing Audioengine speakers to be used with or without a separate subwoofer. It's also worth mentioning that we don’t use any enhancement circuits to add fake bass, so what you’ll hear is real bass- low and clean.

  • Question:

    Is it true that speaker placement really can make a difference in sound quality?

    Answer:

    There are different theories, but rooms and tastes are different so it's tough to specify a "correct" placement. We suggest you experiment with different locations to see what works for you. As a general rule of thumb for the best sound stage balance, the speakers should be equidistant from side walls and a different distance from rear walls. Our front-ported speakers (such as the A2+, A2+ Wireless, HD3, and P4 speakers) do not need any rear panel clearance for better bass but recommend keeping them a few inches from the rear wall for adequate ventilation.

  • Question:

    Can Audioengine speakers be used outside?

    Answer:

    Absolutely! It's tough to protect speakers and electronics from extreme changes in temperature and humidity. Due to that, we don't recommend the permanent installation of our speakers outdoors. It's fine though (encouraged even) to bring them outside with you all day, and our speakers are simple to set up and take down, making them perfect for this!

  • Question:

    Do I need a separate receiver for Audioengine powered speakers?

    Answer:

    Nope! Audioengine powered speakers have amplifiers built-in. This means you don't need any extra equipment, other than a source to play music on (smartphone, tablet,  computer, CD player, turntable, etc). Just plug your source directly into the inputs on the rear panel of the left speaker with the included cables, or connect to them via Bluetooth, and voila! You're listening to music!

  • Question:

    Will the sound be affected if I place the left (active) speaker on the right side and the right speaker on the left?

    Answer:

    Swapping sides will not have any negative effect on the soundstage or quality/clarity of the speakers. This will simply give you the reverse of what the artist intended for you to hear.

  • Question:

    Are two separate stereo speakers better?

    Answer:

    We are firm believers that two quality speakers will always sound better than one or more speakers together in a single cabinet, regardless of the amplifier or sound enhancing technology used. There are some decent one-piece speaker systems that simulate stereo and surround sound from a single source but most fall short as they can’t accurately duplicate a wide sound stage with imaging as complete and rich as Audioengine speakers.

  • Question:

    Do Audioengine speakers have an auto-sleep, idle, or auto-power-off function? Can I leave them on all the time?

    Answer:

    Yes they do! They are equipped with a power-saving circuit that turns off the speaker's final stage amp. This idle mode activates right after you stop playing music. Due to this power-saving function, it's perfectly fine for the speakers to stay on all the time!

  • Question:

    Can I use a subwoofer with Audioengine powered speakers?

    Answer:

    Even though Audioengine speakers have big and tight low end (which will easily fill a room and rival floor standing speakers many times their size), you can also connect an external sub if you wish. You can do so by connecting your Audioengine speakers to your sub's line-level output, or you can even add our W3 wireless adapter for a wireless subwoofer!

  • Question:

    Why do I have to plug one speaker into the wall?

    Answer:

    Audioengine powered speaker models have a built-in power amplifier in the left speaker so you won’t need a stereo receiver or other extra components for power.

  • Question:

    Can I increase the length or change the speaker wire between each speaker?

    Answer:

    Sure. For the best audio performance we’ve included 6.5 feet of 16 gauge wire with each powered speaker system but any "stranded" speaker wire will work. The speaker binding posts on the back of each cabinet will accept bare stranded wire, however you can also use wires terminated with spade lugs, banana plugs, or pins.

  • Question:

    Can Audioengine speakers be placed on their sides?

    Answer:

    Yes, and we recommend that you position each so the tweeters are facing outward.

  • Question:

    Will Audioengine speakers work with a PC or Mac?

    Answer:

    Absolutely! Use the computer's headphone output, soundcard, or DAC audio output from your Mac or PC directly into Audioengine speakers and you're good to go. PC, Mac, laptop or any computer.

  • Question:

    Is it OK to connect Audioengine active speakers to my stereo receiver or integrated amplifier?

    Answer:

    Because Audioengine active speakers already have an amp built in, you never want to connect it to the amplifier output of a stereo amp or AV receiver that would typically connect with bare speaker wire or banana plugs. If you want to use an existing AV receiver as an input switcher and that system has preamp outputs (these would typically be RCA), you could connect these to the RCA inputs on your Audioengine powered speakers.

  • Question:

    How can I stream music from my computer to multiple Audioengine speakers or other stereo systems?

    Answer:

    Check out our W3 Wireless Adapter set. These adapters allow you to stream wireless audio from any program/website/player to our speakers and subwoofer.

    Apple's AirPort Express, the SONOS Connect, and Google's Chromecast Audio are other options that can be added to Audioengine speakers. Where the W3 is a self-contained solution, these products instead rely on your existing home network to send music to multiple speakers at once.

  • Question:

    Why do I hear my phone's notifications over Bluetooth?

    Answer:

    A Bluetooth connection works just like a wired connection, so you'll hear any sounds from your device that would normally play when using headphones, for example. The speakers' job is to project whatever sounds are being fed to them, which means when there are sounds you do not want your speakers to play, you have to manage it from the device that is making the sound. Most phone users will manage this by putting their ringer and notifications on silent mode, or if your device has the ability, choosing to play those sounds through the internal speakers rather than the the Bluetooth speakers.

  • Question:

    Why don't my speakers have more bass?

    Answer:

    If the speaker wire connections on one side are swapped, this can result in a sound that is "scooped" where the lower frequency sounds that are mostly equal between the left and right speakers are reaching you out of phase with one another. This can result in the speakers sounding like they are lacking in bass. To check for this, make sure that the speaker wires are connected to the same color 5-way binding post on each side.

  • Question:

    Where do I connect the ground wire from my turntable to the speakers?

    Answer:

    There isn’t a need to connect a ground wire as this is a connection that is needed between the turntable and it's phono preamp (whether the preamp is built into the turntable, or external).  When going from the very low level of a phono cartridge, it's easier to pick up noise when bringing this signal up to line level, and the ground wire helps with this.  On an internal preamp turntable, this connection is located inside the turntable. When going from the line level RCA out of a turntable with an internal phono preamp or the line level outputs from an external phono preamp to the inputs on your speakers, this connection is not needed.

  • Question:

    Are Audioengine products compatible with Bluetooth 5.0?

    Answer:

    Yes! We incorporate all the relevant functions and features from Bluetooth 5.0 that apply to our products! These features include; extended range, low latency (so that video and audio sync properly), as well as higher level aptX-HD, aptX, and AAC codecs (with the exception of our 512 portable speaker which supports SBC only). Keep in mind that the capability of the source is what controls the Bluetooth experience.

  • Question:

    Will the A2+ Wireless’s range work between more than one room inside my house?

    Answer:

    In most cases, Yes! The overall range you can expect will vary depending on the device you use with the A2+ Wireless, as well as things like the type of construction used in walls you'll be transmitting through. In our testing, most mobile devices like smartphones and tablets will have the best range, some of which can exceed 100 ft in good conditions, even through one wall. Laptops and desktop computers in our testing generally had less overall range with an average of around 70 ft in similar good conditions through a single wall.

  • Question:

    Do I need to install any special software apps or drivers for the A2+ Wireless?

    Answer:

    No extra software or drivers are needed. The A2+ Wireless is compatible with any device that supports Bluetooth, and the A2DP profile for streaming stereo audio. This includes most smartphones, tablets, and computers. For computers that don't include BLuetooth support out of the box, you can simply add a USB Bluetooth adapter.

    The same is also true for the USB connection on the A2+, which uses plug-and-play drivers provided by your computer's OS. The A2+ USB input is compatible out of the box with Windows and Mac computers, iPhones and iPads when using Apple's lightning USB 3 adapter along with a fast wall charger, and should work with most Android Smartphones and Tablets as well.

  • Question:

    If A2+ Wireless is paired and connected to my phone via Bluetooth, do I need to do anything else to play music?

    Answer:

    Once your A2+ Wireless is paired and connected via Bluetooth, then any app (TIDAL, Music, Spotify, etc.) will automatically play your music through Bluetooth.

  • Question:

    Will my music have a delay through the A2+ Wireless if I’m watching a movie or music video?

    Answer:

    Though overall latency can be affected by some external factors (including but not limited to signal strength, and even simply being physically further away from the speakers), Bluetooth on the A2+ Wireless generally has a delay of about 30ms (milliseconds) so you should be able to watch videos from Youtube, for example, and stream out the audio to the A2+ Wireless without any significant or noticeable lag between the video and audio.

  • Question:

    Can I connect multiple sources to the A2+ Wireless? Can I stream via Bluetooth and use the USB input at the same time?

    Answer:

    Yes, you can use multiple sources with the A2+ Wireless just fine. The analog inputs on the A2+ Wireless are always active. They will play at the same time as the Bluetooth or USB input. However, Bluetooth and USB share the internal DAC, so you can only listen to one at a time, and Bluetooth takes priority. If you're using USB for example, and start using Bluetooth, USB will mute and Bluetooth will take over. Depending on your source, if you pause or disconnect from Bluetooth the speakers may automatically switch back to USB after a few seconds.

  • Question:

    Is the A2+ Wireless compatible with TIDAL music streaming service?

    Answer:

    The short answer is yes! You can use TIDAL on any compatible source device (PC, Mac, iPhone Android, etc.). The A2+ Wireless is compatible with all of these devices as well since they almost universally also include Bluetooth.

  • Question:

    OK, so If I can use the A2+ Wireless with TIDAL, how come you're not listed on TIDALs website?

    Answer:

    From what we understand the devices listed on TIDAL’s website are network media servers with the TIDAL app already installed on their operating systems, that’s all. No difference in audio quality or anything else as compared to their downloadable app, just that TIDAL comes pre-installed on those devices. The only notable exception is that if you're listening to TIDAL on a computer, the only web browser that supports the full audio quality is Google Chrome.

  • Question:

    Does A2+ Wireless come with speaker grills?

    Answer:

    Our woofers are made of aramid fiber and the tweeter domes are silk. Both of these materials are very robust and can handle quite a bit of abuse. For our A-series speakers we decided against grill covers as they do tend to color the sound a bit. However, without speaker grills they are more cat and kid-friendly! If you do prefer speakers with grills, you can check out our HD3 speakers here:

  • Question:

    Can I use the A2+ Wireless with my iPad or iPhone via USB to bypass the internal DAC and get better sound?

    Answer:

    Absolutely! You will need to pick up Apple's Lightning to USB 3 Camera Adapter, which allows a USB connection to the iPad (and, as of iOS7, the iPhone). Then just hook up as you would from a computer. You can even charge your iPhone or iPad while you use it this way!

  • Question:

    I'm using a Turntable with my Audioengine speakers, and it gets noisy when I turn the volume up. What gives?

    Answer:

    This can sometimes happen when the speakers and turntable are placed on the same surface.  The vibrations from the speakers playing feedback into the turntables stylus, causing unwanted noise.  The best way to mitigate this would be to place the speakers on a different surface.  If that's not an option, we'd recommend trying out some isolation stands.  For larger speakers like A5+ and HD6, the ones made by Isoacoustics work well.

  • Question:

    Can I use the A2+ Wireless with other tablets or smartphones like Samsung Galaxy or Microsoft Surface?

    Answer:

    Yes! If your tablet or smartphone has a USB output and supports USB audio (refer to the manufacturers’ documentation), then it will work with A2+ Wireless's USB input. You'll most likely also need an OTG adapter cable to connect from your tablet to the USB input on the A2+ Wireless. These are generally available from the manufacturer of your tablet/smartphone, local electronic stores, or even online retailers.

  • Question:

    Should I use the volume control on the front of the A2+ Wireless or can I adjust from system volume on my computer?

    Answer:

    If the left speaker is in an easy to reach location, you can certainly use the physical knob to set volume. If not though, it's perfectly fine to set the A2+ to a good volume and adjusting from source. Every setup is different, so some experimentation will be necessary to find your prefered settings, but around 11 or 12 o'clock is a good starting place.

  • Question:

    Can I take my Audioengine speakers to another country with a different voltage?

    Answer:

    Yes, you can. The A2+ Wireless speakers use a switching power supply so it will automatically convert to the different voltage. The power cable is also detachable which makes it convenient to replace the AC plug with a different type if you don’t want to use an adapter plug.

  • Question:

    Do higher power output ratings for audio gear mean louder or better sounding speakers?

    Answer:

    Not necessarily. Audioengine speakers and amplifiers are very efficient, and designed together as a system so therefore we get more volume output than stereo receivers or amplifiers that might higher wattage or power numbers. Due to this tuning, we achieve big sound outputs with a fraction of the power required by other systems.

  • Question:

    Can you stream music wirelessly to the A2+ Wireless with an Audioengine wireless adapters instead of Bluetooth?

    Answer:

    Yes, an AC wall outlet near the A2+ Wireless is all you need to power the W3 or D2 wireless receiver.

  • Question:

    Can I drill holes in my Audioengine speakers and mount them to a wall?

    Answer:

    Due to the electronics, cabinet materials and finish, it's not a good idea to drill into your speakers; however, we have provided an integrated 1/4" threaded insert on the bottom of each cabinet to use with wall mounts. You can also use side clamping mounts, although mounts that clamp from the front and back may obstruct the bass port.

  • Question:

    Can I turn Bluetooth off?

    Answer:

    When you power one of our Bluetooth products on, they will be available to connect to for just a few minutes. Although you cannot turn the Bluetooth off manually, if nothing pairs or connects within that first few minutes, Bluetooth will automatically turn off.  You would then just have to press the pairing button (or power the unit off and on again) to turn the Bluetooth back on when you're ready to pair or connect again.

  • Question:

    When using the USB input of the A2+ Wireless, what bit rate and bit depth should I set my system to?

    Answer:

    The A2+ Wireless internal DAC handles up to 48K transfer rate, and up to 16 bits bit-depth. Your system will generally default to these settings when you hook up the A2+ Wireless. If you mainly use 44.1K files, you might set this as the default in your system. Many system players like JRiver and Amarra will default to the proper bit rate automatically.

  • Question:

    How easy is it to set up A2+ Wireless?

    Answer:

    A2+ Wireless is an all-in-one system with no extra components needed except your phone or computer. Simply place the speakers where you want them and connect the power supply. Hook up the included speaker wire from the powered left speaker to the right passive speaker. Then connect your music source with the supplied cables - or go wireless with any Bluetooth enabled source device, like a computer, smartphone, or tablet.

  • Question:

    What if my source doesn't support aptX? Can I still use the A2+ Wireless and if so, how will it sound?

    Answer:

    You can absolutely still use the A2+ Wireless and it will sound great. AptX is a high-quality Bluetooth audio codec that works really well. In addition aptX, and the default Bluetooth codec SBC, The A2+ Wireless support other high quality audio codecs, like AAC for use on Apple iPhone and iPads, as well as Android devices that do not include aptX.

  • Question:

    What does the white indicator light on the A2+ Wireless rear panel mean?

    Answer:
    • If it's on and solid, this means the A2+ Wireless is powered on, and currently connected to a Bluetooth-enabled device.
    • If it's on and blinking, this means the A2+ Wireless is powered on but not currently connected to a device.
    • If it's off (and A2+ Wireless is powered on), this means Bluetooth is in standby and not connected to a device. The A2+ Wireless, however, is still visible to your device, so simply connect using your device and it will automatically wake up.
  • Question:

    Is the A2+ Wireless designed only for use with Bluetooth devices?

    Answer:

    The A2+ Wireless work excellent via Bluetooth, but they can also be used wired, with more traditional source devices like Turntables, CD players, or anything else with a standard analog audio connection like RCAs or 3.5mm stereo-mini. They also include a USB port for use with a Windows or Mac computer, as well as many Smartphones and Tablets with the right USB adapter cable.

  • Question:

    The sound quality of my computer's headphone jack isn't very good but I want to connect my Audioengine speakers. What do I do?

    Answer:

    The headphone outputs on many computers will sound great with the A2+ Wireless. Some do have poor audio quality though, so if this is the case for your computer, try connecting from the USB port to your with A2+ Wireless, or connect wirelessly via Bluetooth.

  • Question:

    The A2+ Wireless has a built in USB digital-to-analog converter (DAC), but can I also use a different DAC?

    Answer:

    While the DAC in the A2+ Wireless is better than what is built into most computers, adding a 24-bit DAC, such as our D1 or D3, would still be a benefit to audio quality.

  • Question:

    If I connect my turntable to the A2+ Wireless will it be necessary to purchase a phono preamp or can I simply connect the turntable directly to the A2+ Wireless input?

    Answer:

    Some turntables will need a preamp before being connected and others may have one built-in. Check the turntable manufacturer’s website or user manual. Some turntables may even include Bluetooth, in which case you can pair and connect them to the speakers wirelessly!

  • Question:

    When I connect a turntable to my A2+ Wireless, why is the volume extremely low?

    Answer:

    Some turntables do not have a built-in preamp and as a result, you will need to add an external phono preamp between your turntable and A2+ Wireless. Many turntables, however, (such as the Music Hall USB-1 or Audio Technica AT-LP120) have a built-in preamp and include a switch on the back for "line" or “phono”. For Audioengine powered speakers you want to select "line".

  • Question:

    If my speakers are in idle mode why can I still hear a faint hum or hiss if I put my ear very close to the speaker?

    Answer:

    Even though the final amp stage is shut down during sleep, the pre-amp stage is still powered up so a slight hiss is not uncommon. If you have an analog audio cable plugged in to the speakers but not into anything else, it's possible this could be picking up some noise as well.

  • Question:

    What if my speakers or subwoofer have a hum or buzzing sound?

    Answer:

    Hum or buzz in the speakers is usually caused by something external to the speakers which is coupling noise into the speaker system (either through the AC lines, cordless phone, wireless router, or directly from the source input). A common reason is that the entire system is set up such that a "ground loop" results. Basically, a ground loop occurs when the AC power grounds and the system signal grounds are not at the same electrical potential. Refer to our online Setup Guides for a list of things to try.
