Make sure to maximize your audio source volume/s connected to the N22 and lower the N22 volume dial to minimize naturally occurring noise floor that can come thru the speakers when amplifiers are turned up high.

We take great pride in our products, and go through great lengths to ensure consistency and quality. For that reason, this item was randomly selected for an additional step of Quality Assurance.

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.

On the A2+ Wireless/HD3 models with an external power supply brick, first test it by plugging into wall power and observing the LED light on the brick to see if its solid, blinking, out. If it's blinking or out, the power supply is likely faulty.

If the light is solid, proceed to plugging into the speaker and observe the power supply brick LED once more. If it's blinking or out, there is likely an issue with the internal amp. Contact support if either has an issue.

This is actually normal behavior. It's is a tradeoff of using an analog potentiometer for the N22. Analog potentiometers are tactile, and don't require a microprocessor like a digital encoder would, but they sometimes do have some volume imbalance at lower levels. An easy solution for this is to raise the volume of your N22, and lower the volume at your source device.

Yes, plugging in headphones will bypass the speaker output so audio will play through your headphones only.

Sure, the N22 has a power-saving idle mode that activates after you stop playing music.

The N22 needs to be kept upright with the stand attached for proper cooling.

Yes, the N22 uses an external switching power supply so it will automatically convert to a different voltage when plugged in. 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.

Yes, the N22 amp + P4 passive speakers + W1 or W3 wireless stereo adapter will make a great-sounding wireless rear channel setup.

Yes, simply connect the full-range output of the N22 into your sub's line-level input. The sub and speaker volume can be controlled together by the N22 volume control.

Sure. We've included two 5-foot, 16-gauge speaker wires with the N22 but any "stranded" speaker wire will work. The standard-size speaker binding posts on the back of the amp will accept bare stranded wire, however if you want to terminate the wires we recommend using spade or pin-type terminals.

Yes, the N22 will work well with headphones or earphones with an impedance from 16 to 300 ohms.

The N22 is an efficient design and works great with any 4, 6, or 8 ohm passive speakers, including the Audioengine P4!
