Cabinets

To minimize unwanted resonances and distortion, Audioengine cabinets have thick high-resin MDF walls with extensive internal bracing. Heavy internal sound-damping material is used to reduce unwanted sound reflections inside the cabinet. All cabinet edges are rounded which look great and reduce high-frequency diffraction effects on the front baffles. The A1 cabinet contains tuned, front-port slots.

Furniture Grade Finishes

The A1 cabinets are in versatile, grey finish offering a modern compliment to any small space or desktop.

Custom Components

Audioengine designs and manufactures our own tweeters, woofers, and other critical components. In other words, these are not “box built” speakers with off-the-shelf parts but custom-designed to our specifications. What we do not fabricate directly in our factory we have made to our designs (parts such as transformers, magnets, and wiring harnesses, for example). The cabinets, drivers, bass port designs, amplifiers, and crossovers are all painstakingly tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires much less power than passive speakers and a separate integrated amplifier or similar A/V components.

Based On Studio Monitor Designs

Studio monitor speakers are used by producers and engineers in recording and production studios. They are designed with a theoretical flat frequency response which allows the engineer to create a final mix in such a way that the recorded music will sound good on most other speakers. Although Audioengine speakers are not designed to be up-close “nearfield” studio monitors, we do carry over much of the same higher-end technology, components, and design philosophy for all Audioengine speaker systems.

Efficient Integrated Design

The speaker cabinets, drivers, innovative bass port designs, amplifiers, and passive crossovers are all critically tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires less power than passive speakers and a separate integrated amplifier or similar A/V components. We build all this goodness into the left speaker cabinet to make it super-easy to connect your smartphone, tablet, computer, TV, network player or any other audio product.

High-quality Bluetooth Audio

The Bluetooth built into the A1 Wireless speakers features aptX coding which is an advanced Bluetooth audio codec with very impressive sound. And even if your phone or tablet does not have aptX, the A1 Wireless Bluetooth solution is backwards-compatible with SBC and AAC codecs, so you can wirelessly stream music from any Bluetooth-enabled device and still enjoy all your music. High-fidelity Bluetooth aptX that really works and sounds great.

Extended-range wireless. Most Bluetooth implementations have very limited range, typically within just one room. But with careful signal management circuitry and antenna tuning, we offer a superior solution that has up to 3 times the range of standard Bluetooth for multi-room use, with no degradation in audio quality.

16 bit DAC
The A1 Bluetooth receiver utilizes the PCM 2704C DAC, known for extremely-low quantization noise in the audio band, with a built-in analog low-pass filter that removes the high-frequency components of the noise-shaping signal.

Amplifier Design

The amplifiers in powered Audioengine speakers are located in the left speaker and are a conservatively-rated class D analog monoblock design. This is a more traditional speaker/amplifier marriage which provides excellent quality audio and greater flexibility. All circuit boards for the power and preamp sections are vertically mounted for maximum mechanical shock protection.

Driver Designs

Audioengine uses audiophile-quality, ferrofluid-cooled silk dome tweeters with neodymium magnets. Silk tweeters hold up well under high power and the edge-driven design gives very smooth response. The woofers are aramid fiber woven glass composite with rubber surrounds. Aramid fiber is obviously very strong, which means the woofer retains its shape when being driven at high levels.

Shielding

Both drivers are directly video shielded and allow the user to place the speakers within a few inches of a video monitor. This shielding also offers protection for hard-drive digital music players.

Troubleshooting

A1 Troubleshooting Tips

The following troubleshooting tips can help diagnose and correct most concerns with the A1. We have attempted to make this list as comprehensive as possible, so some of these may not apply to your issue, but please go through each tip.

If the power indicator on the A1 is not illuminated, try these tips:

  1. Make sure the AC power cord is connected to the power supply unit and to a working AC power outlet.
  2. Check that the cable at the other end of the power supply is correctly connected to the rear panel of the left speaker.

If the power supply light is on but you are experiencing an audio-related issue with a wired connection, try these tips:

  1. Verify that the volume/power control on the rear panel is not turned all the way down or powered off (we recommend setting the volume to at least the 10 o’clock position)
  2. Check that the volume level of your audio source components or devices is not set to minimum volume or powered off.
  3. Check speaker wire connections from the left (powered) speaker to the right (passive) speaker. Confirm this by removing the speaker wire from on each speaker and reconnecting.  Also check the speaker wire polarity by verifying that the wires are going to same terminals on both speakers.
  4. Check that the cable from your audio source to the speakers are properly connected. Confirm this by unplugging the audio cable and then reconnecting.
  5. Decrease the volume of the input audio source and increase the volume of the speakers.
  6. Try using different audio input sources and/or devices to see if the problem follows.
  7. If you are using a computer with your A1, make sure the volume is up on your media players, internet radio, master control, device volume, etc. and the balance control is centered.

If your input source has its own EQ, please make sure the low end is at a moderate level, as having too much bass can cause distortion.

  • If you are using a wireless adapter, preamp, or external DAC with these speakers, remove them (temporarily) and connect the audio input source directly to the speakers.
  • Move your speakers to a different location to see if something is causing interference in the current setup.  Something as simple as a wireless internet router, cordless or mobile phone, or halogen lamp near the speakers can cause interference.

A1 troubleshooting tips – Bluetooth

  1. Verify that the A1 is connected to power and that the front volume knob is turned clockwise past the detent position (you should feel a click).  If you haven’t already, power-cycle your speakers by switching them off and back on.
  2. If your A1 is already connected to a device via Bluetooth, the Bluetooth pair light on the back panel of the left speaker will be on and solid (note that if your A1 has been idle and not connected to a device for more than 2 minutes, the Pair light will automatically turn off).  Tap the Pair button and it should begin blinking (or pair to your A1 using your source device, and the LED will go from off to on and solid).
  3. Try playing audio from more than one application on your phone/tablet, or computer.
  4. Check to make sure your source device (computer, tablet, phone, etc) is running the most up-to-date version of software available. For Mac OS users, be sure to check the App store to see if there's a newer version of Mac OS you could be running.
  5. Try disconnecting from and forgetting the A1 through your device’s Bluetooth settings, and re-pairing to the A1.
  6. Try using a different source device with your A1 to see if the issue follows.  Also be sure to test your A1 using the analog input as well.
  7. If possible, try your A1 in a different location to see if something is causing an issue in the current setup.  Something as simple as a wireless internet router, cordless or mobile phone, or halogen lamp near the speakers may be causing interference in your setup.

FAQ's

Absolutely!  Our speakers are safe to place sideways and, from our experience, sound great. When doing so, we recommend that you position each so the tweeters are facing outward.

The speakers we offer that are designed to have a remote control are the A5+ Classic, A5+ Wireless and HD6.

The following systems do NOT support a remote control:  512, A1, A1-MR, A2+, B2, HD3, HD4.

There can be only 1 active pairing at a time.

No, there are no firmware updates or special drivers needed unless you own our A1-MR multi-room speakers or our B-Fi multi-room wireless streaming device.

If a firmware update is released for the A1-MR or the B-Fi, you will be notified of the update the next time you open the Audioengine Control App.  If an update is needed, simply click "update" on the DEVICES page next to the product that needs to have the firmware update applied.  The app will handle the rest of the process from there!

Standard plug-n-play drivers that are provided by your computer's OS are utilized when using the USB input on our A2+, HD3, and HD4 speaker models.

And all of our Bluetooth speakers/products are 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.

                             Applicable to our A1, A2+Wireless, B2, A5+Wireless, and HD6 speaker models

Turn on the speakers using the power switch located on the rear panel.  The speakers will automatically go into Bluetooth "pair mode" and the Pair button on the back panel should start flashing.

  1. On your source device (phone, tablet, laptop, etc), turn on Bluetooth and go to Bluetooth preferences.
  2. Select "Audioengine (your speaker model)" from the list of available devices to pair and connect.  The Pair indicator on the back panel should now be solid. Play your music and adjust the volume levels on the speakers and your device.

To add additional devices put the speakers back into pair mode by disconnecting them from your device or by pressing and holding the Pair button until the pair indicator starts flashing.

Our speakers can wirelessly connect to only one device at a time, however it will remember up to six different devices.

If your A1 or A1-MR speakers sound distorted, are buzzing, or just don't sound quite right, we'd recommend the following troubleshooting steps:

Start with power cycling your speakers by turning them off and then back on.  From there:

  1. Determine if the distortion is due to your source by disconnecting all source devices from the speakers.
  2. Please make sure all of your connector cables are in working order. Try different cables as well as a different source device.
  3. Please try using the stereo mini input and Bluetooth (or WiFi in the case of the A1-MR), one at a time, to see how the speakers react.
  4. Make sure it is not a power issue by trying a power outlet that is on a different circuit.

Applicable to our A1, A1-MR, A2+, HD3, HD4, A5+, and HD6 speaker models

If one of your speakers is not working (whether it be the left or right speaker), we would recommend the following troubleshooting steps:

Start by power cycling your speakers by turning them off and then back on.  From there:

  1. Check to make sure the speaker wire connecting the left and right speakers is connected according to proper polarity (Red to Gold, Black to Silver) on both ends.
  2. Please make sure all of your connector cables are in working order. Try different cables as well as a different source device.
  3. If you are using any other devices in line with these speakers, please temporarily remove them from your setup and connect the source directly to the speakers
  4. Please try using each available input, one at a time, to see how the speakers react. When testing via RCA swap the RCA jacks (red to white and white to red) to see if the issue remains in the same channel.

If the issue persists, please click on the following link and then click on the dropdown to submit an email to our Support team:

When doing so, please copy and paste the above troubleshooting steps along with the results of each and include this information when contacting us.

Yes, you still need to connect the active/left speaker to the passive/right speaker via the included speaker wire. The passive right speaker has no power source of its own and relies on the amplified signal coming over the wire.

You can use either a single LFE RCA cable or stereo white/red RCA cable.

Connect FROM your powered speaker's 'Subwoofer' output TO your subwoofer's 'Left' RCA input or the subwoofer's LFE input.

For stereo RCA cables, just use the left/white RCA cable, and leave the red RCA disconnected to prevent an accidental ground loop.

** Please note:  a 3.5mm/stereo mini cable will not work with the 'Subwoofer' output on the back of your A1/A1-MR speakers. **

If the Bluetooth pairing light is solid (any color), an active connection to another device has been established.  Under most circumstances, our Bluetooth speakers/B1 only supports a single active connection at a time.  So if someone else in your home has connected to your Bluetooth device/speakers, this could surely keep you from connecting another device to it.

There is no on/off switch with the our Bluetooth devices or speakers, so once it's plugged into power it's on. The Bluetooth LED light will blink and be discoverable for 5 minutes once powered on. If in that 5 minute window it connects to a Bluetooth source, the light will go solid. After the 5 minutes is up, the light will turn off and it will no longer be discoverable by new sources, but it will still be on. If the LED is off, any previously connected device can still pair to it at any time from their device. If you want to pair  to a new device, just tap the LED light once more and it will blink and be discoverable for another 5 minutes.  If your Bluetooth device/speaker is connected to something and you want to disconnect that particular device, you can hold the button down for a few seconds before it disconnects and goes back into the flashing cycle.

 

If the above does not help address the issue you are experiencing, we'd recommend going through the below list of troubleshooting tips:

If you haven’t already, power cycle your Bluetooth speakers/B1 by unplugging the power connection, and reconnecting it.

1) Please make sure all of your connections are complete; also, check that all of your connector cables are in working order. You will want to swap out some interconnects to test for this.

2) Try playing audio from more than one application on your source device (phone, tablet, computer, etc.)

3) Check to make sure your source device is running the most up to date version of software available. If an update is available, make sure you restart your device after the update is installed.

4) Try disconnecting from, and "forgetting" the Bluetooth speakers/B1 through your source's Bluetooth settings. Then, try re-pairing and connecting to the two.

5) Try using a different source device with your Bluetooth speakers/B1 to see if the issue follows. Try using the analog as well as the digital optical output, to see if you have this issue with both connections.

6) If at all possible, try your Bluetooth speakers/B1 in a different location and / or setup to see if something is causing interference in the current location. Something as simple as a router, cordless / mobile phone, halogen lamps, etc. near the speakers may be causing the issue in your setup.

 

Yes! We designed the A1 Speaker System for quick and easy setup. First, simply place the speakers in the desired location and connect the AC power cord. Hook up the included speaker wire from the powered (left) speaker to the passive (right) speaker. Then, connect your source device with either of the supplied cables. Additionally, you can connect wirelessly to any Bluetooth enabled phone, tablet or computer.

Yes. In addition to aptX, and the default Bluetooth codec SBC, the A1 supports other high-quality audio codecs, like AAC, for devices that do not support aptX.

No. The A1 offers wired or wireless playback for extended range streaming via aptX Bluetooth. It can additionally connect to your turntable, computer or TV with a standard AUX cable (3.5mm, 1/8", mini TRS, etc.).

    • If it's on and solid, this means the A1 is powered on, and currently connected to a Bluetooth-enabled device.
    • If it's on and blinking, this means the A1 is powered on but not currently connected to a device.
    • If it's off (and A1 is powered on), this means Bluetooth is in standby and not connected to a device. The A1, however, is still visible to your device, so simply connect using your device and it will automatically wake up.

Yes. The A1 will work with both the Audioengine W3 Audio Adapter and the B-Fi Mulitroom Music Streamer.

The A1 offers high-definition aptX Bluetooth with an extended range of up to 100 ft.

No. The A1 is a premium powered, plug and play stereo system that will easily connect to any Bluetooth enabled phone, tablet or computer in seconds. After a quick setup with the included power cord and speaker wire, immediately start streaming music from your favorite music services (TIDAL, Spotify, Pandora, Amazon Music and more) or directly from your music library.

The A1 is a high-performing, low latency stereo system with high-definition aptX Bluetooth. Seamlessly stream movies and YouTube videos without any significant or noticeable lag between video and audio.

Yes! With the A1, use any Bluetooth enabled phone, tablet or computer to wirelessly stream all of your favorite music services, including TIDAL.

Your Bluetooth connection works by projecting the sound from your phone. So, if your ringtone volume is on, that sound will come through Bluetooth too. This is a simple fix by changing the phone's ringtone settings to either vibrate or silent.

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 speakers to a good volume and then adjust from your source moving forward. Every setup is different, so some experimentation will be necessary to find your preferred settings.

Though overall latency can be affected by some external factors (including things like signal strength, how well the source device's manufacturer has implemented it's Bluetooth, and even simply from being physically further away from the speakers) Audioengine Bluetooth products have very low latency when compared to most Bluetooth receivers, 30ms or less.

Here are some tips you can use to minimize any latency issues you may run into with your Bluetooth setup:

1) Try restarting both your device as well as the speakers (by switching them off, and back on, with the power switch on the rear of the speakers).

2) Check to make sure your source device is running the most up to date version of software available.

3) Try disconnecting from and forgetting the your Bluetooth speaker or device through your source’s Bluetooth settings, and then re-pair to your Bluetooth speaker/device.

4) If you have multiple apps or windows open when the delay occurs, try closing all of the apps that are not currently in use.  The more multitasking your system is having to do, the greater the potential delay in audio when using Bluetooth -- this would apply to both your smart phone and computer.

5) When using your iPhone, we've found that resetting your network settings can help improve the overall functionality of Bluetooth with your device -- including the latency.

Setting up your Bluetooth turntable with your Bluetooth-ready Audioengine speakers/components should be simple! First, you would also need to make sure your Audioengine Bluetooth device is on, in pair mode (LED light flashing), and near the turntable. Next, you would need to use the pairing button to send the turntable into pairing mode. Depending on the turntable, you will need to either press and release the turntable's pair button or press and hold it; for example, on the Audio Technica AT-LP60-BT you would need to hold the turntable's pairing button for about two seconds, until the light flashes different colors. Once the turntable is in pairing mode, it will search and connect to the nearest available Bluetooth device. Once the turntable if paired and connected to your Audioengine Bluetooth device, the pair light on the receiver should turn solid.

If you’ve connected your turntable to your speakers and the volume is low, one of two situations may be happening:

If you have a turntable with a built-in phono preamp, such as the Audio-Technica ATLP120 or the Music Hall USB-1, the output may be in the wrong setting. Double check and make sure the switch is set to “line” instead of “phono.” Be careful to keep the volume of your speakers low as it can be quite loud if you had to switch it to "line".

Your turntable could also not include a built-in phono preamp, such as older turntables. If your turntable does not include a built-in preamp, you will need to add an external preamp to bring the signal up to a line level signal. We don’t have any recommendations on a particular brand or model preamp to use with this setup.

You can have two sources connected at the same time with no need to flip any switches, simply play audio from the source you wish to hear. Though, if you are using multiple sources you may be able to hear both inputs playing simultaneously.
