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, a 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, and you're listening to music!

The A5+ Classic was designed with the user's listening experience in mind and are not marketed as pro audio mixing monitors. However, Audioengine has its roots in the studio monitor world and the A5+ Classic is quite good for this purpose. We've had customers tell us they use these for nearfield listening and music editing with excellent results.

Yes, there are 2 audio inputs on Audioengine powered speakers so connect the Airport Express to one input and the variable output from your TV into the other. Both inputs are "open" or active so you can leave 2 audio sources plugged in at the same time with no need to flip any switches.

The A5+ Classic is not officially supported by any universal remotes. It is possible to use a third party remote, but that remote needs to support IR learning. This is a feature that allows a universal remote to learn commands directly from the remote we supply. The Logitech Harmony remote, for example, is supported by the A5+ Classic.

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, therefore we decided against grill covers for the A5+ Classic as they tend to negatively color the sound. Even though our speakers do not have grills they are still cat and kid-friendly!

This is normal; the volume control for the A5+ Classic is a digital encoder, and uses a micro-processor to attenuate the volume. The light on the front of the speakers should flash as you adjust the volume up and down; once the speakers have reached minimum or maximum volume, the light will remain solid and won't flash.

Nope. The 3.5mm stereo mini and RCA inputs run on the same analog circuitry and will sound equally awesome.

Yes, just switch the voltage selector on the rear panel to match the AC power in your country before powering them on. We recommend changing the fuse when using a different voltage.  For 220 volts, here's the value you would need:5mm x 20mm - 1.6 amps @ 250 volts - slow blow fuse. The power cable is detachable on our powered speakers which makes it convenient to replace the AC plug with a different type if you don't want to use an adapter plug.

Sure, for A5+ Classic you will need about 100-120W.

If the volume control isn't working like you would expect, try turning your A5+ Classic off and then back on. Since the A5+ Classic volume control is a digital encoder, it uses a microprocessor to attenuate the volume. Like most sensitive electronics if left on for an extended period of time, you may eventually experience unexpected operation so they may need to simply "reboot".

If the volume knob feels loose or the volume knob doesn't "click" when pressing it in, it sounds like the nut that holds the volume pot in might just be loose. This can be accessed and tightened without opening the speakers up. Try this:

1. Pull the plastic volume knob off the volume pot.  Depending on how tight it's on, you might be able to pull it off with just your fingers.  If not, look for something fairly flat and preferably plastic with soft edges to pry it with.
2. Use a deep well 10mm socket (or socket driver) to tighten the nut around the volume pots shaft.
3. Press the plastic volume knob back over the volume pot's shaft, and retest.

If you continue having issues after this, please open a support ticket here.

The A5+ Classic's USB port can provide around 500mA, which is standard for high powered USB 2.0 devices; however, both the iPad and the iPhone require around 1000mA to charge with the screen on (the iPad's included USB charger actually provides around 2100mA to speed up charging with the screen on).  If your iDevice is at a higher battery level it should work fine to plug it in to the A5+ Classic to maintain the battery while listening to music (with the screen on it will always show "not charging").  If the battery is low though, we'd recommend plugging it into the charger that came with it.

Our powered speakers are an all-in-one solution with no extra amps or components needed! All you need to do is unpack the speakers, place them where you want, and then plug in the AC cord. Next, connect the included speaker wire from the active speaker to the right passive speaker. Then plug in your music (iPod, CD player, computer, etc.) with the supplied cables and you're ready to go.

Sure, just connect the SONOS analog audio outputs to the A5+ Classic. Use our passive P4 speakers if you have a SONOS CONNECT:AMP.

Some turntables will need a preamp before being connected and others may have one built-in. With that in mind, it is best to check the turntable manufacturer’s website, the turntable’s user manual, or you can even try your turntable without the preamp first to see how it operates.

If the left speaker is in an easy to reach location, you can certainly use the physical knob to set volume. If not though, we generally recommend setting the A5+ Classic at around 50% and adjusting from source.

All you would need to do is connect the variable output of the A5+ Classic into the input of your sub using RCA cables.

You wouldn't be able to use a pair of headphones directly with the A5+ Classic; in order to use headphones with the A5+ Classic, you would need to include something with a dedicated headphone amp, such as our D1. All you would need to do is plug the D1 into your computer (either with an optical or USB cable) and connect the D1 from its RCA outputs into either of the inputs of your speakers.
