Product Description

Simple, Thoughtful Design

Perfectly suited for your desktop or a smaller space in your home or office, N22 is easy to connect to your Mac or PC with no software to install or settings to change. One easy to use dial turns the N22 on/off, and adjusts the volume, with no need for other buttons or knobs. N22 also includes a USB power port that’s perfect for powering Audioengine wireless adapters to stream your music wirelessly from your computer or iPod, or charging your smartphone.


Pair the N22 amp with Audioengine P4 passives (or any speakers) for a high-end mini desktop hi-fi music system. Connect your iPod, computer, and speakers or headphones for a compact and great-sounding personal stereo system. You can even connect a subwoofer to the variable line out and charge your iPod or smartphone through the USB power port. Two audio inputs are standard – RCA and mini-jack connectors – so you can plug in your computer, iPod or stereo directly.

See and Hear the Difference

Unlike many products, stuck in a cheap plastic box, the N22 is wrapped in real wood, and hand finished with the same satin black paint as our powered and passive speakers. The Audioengine N22 Premium Desktop Audio Amplifier sets a new level of audio and aesthetic quality and even further closes the gap between computer and home audio. Even if you’re not an audio enthusiast we guarantee you will still hear a difference!

Upstanding design
The vertical design of the N22 with its integrated stand allows the 22 watt/per channel stereo class A/B amplifiers to run cool through passive convection without a fan or massive heatsink. The N22 fits easily on your desk and doesn’t take up much space.

Discrete headphone amplifier
For headphone enthusiasts the N22 includes a high-performance, low-noise discrete amplifier which works well with all types of headphones and earphones.

USB power
The Audioengine N22 has a built-in power port for iPod charging while listening to your music. The USB connector allows you to charge and power your iPod, iPhone, Audioengine wireless adapters or any other USB powered product. USB is for power only, not USB audio or data transfer.

Variable line out
The N22 includes a variable preamp output so you can connect a subwoofer, external amplifier, or Audioengine wireless adapter and control the volume of the line-out from the front panel.

Simple operation
Both audio inputs on the N22 are active so two audio sources may be connected to the amplifier at the same time without the need for an input switch. A standby idle mode is also included to conserve power when you’re not playing music.

Wireless rear speakers
Use the N22 amp, Audioengine P4 passive speakers, and our W3 wireless adapter for a low-cost but great-sounding wireless rear channel setup for your home theater.

Macworld – N22 Review

“…bass was strong and tight, and high frequencies natural without artificial harshness. When I pushed the N22 to louder volumes, it continued to perform well.”

What type of speakers work best with the N22 amplifier?
The N22 is an efficient design and works great with any 4, 6, or 8 ohm passive speakers, including the Audioengine P4!

Will my low impedance (low Z) Grado headphones work with N22?
Yes, the N22 will work well with headphones or earphones with an impedance from 16 to 300 ohms.

When I connect a turntable to my N22, why is the volume is extremely low?
Some turntables may not have a built-in preamp and you would need to add an external phono preamp to bring the instrument level signal of the turntable to line-level. Some turntables may have a built-in preamp but have a switch on the back for either “line” or “phono,” such as the Music Hall USB-1 or the Audio Technica AT-LP120; the switch would need to be selected to “line” in order to work directly with the speakers.

Can I increase the length or change the speaker wire between the N22 and each speaker?
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.

Can I connect a subwoofer to the N22?
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.

Is it possible to use the N22 amp to power the rear channels of my surround system?
Yes, the N22 amp + P4 passive speakers + W1 or W3 wireless stereo adapter will make a great-sounding wireless rear channel setup.

Can I take my Audioengine N22 to another country with a different voltage?
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.

Is it OK to remove the stand attached to the N22 and place the amp on it’s side?
The N22 needs to be kept upright with the stand attached for proper cooling.

Can I leave the N22 power on all the time?
Sure, the N22 has a power-saving idle mode that activates after you stop playing music. If I plug in headphones will the N22 mute my music playing through the speakers? Yes, plugging in headphones will bypass the speaker output so audio will play through your headphones only.
