Unpacking

Your Audioengine N22 amplifier was carefully tested and inspected before packaging and shipping. After unpacking please check for any damage. It is rare that any damage occurs during shipping, but if this does happen contact the shipping company immediately. We recommend that you keep the original carton and packing material.

Setup and Operation

Step 1 – Placement
Set the N22 amplifier on a solid surface and make sure there is plenty of ventilation and space around the amplifier top and bottom. The integrated stand is not designed to be removed as the N22 uses a passive convection system for heat dissipation. Keeping your N22 upright with the stand attached is important for optimal ventilation and to keep your N22 running cool.

Step 2 – Connecting the Speaker Wire
The N22 is a stereo power amplifier that will power one pair of passive speakers between 4 and 8 ohms. To connect N22 to your speakers you will need 2-conductor stranded speaker wire, which is included. The N22 uses high quality, five-way gold plated binding posts that will accept heavy gauge bare wire, banana plugs, spade lugs, or pin terminators. If you use your own speaker wire we recommend using at least 16 gauge wire and using the same length of wire from the amplifier to each speaker. It’s also a good idea to turn off your amplifier before connecting power, audio sources or speakers.

Preparing the Speaker Wire

1. Separate the last 3” of each speaker wire conductor.
2. Strip ½” of insulation from the end of each wire.
3. Twist the exposed copper strands with your fingers 3 or 4 times so the strands stay together.

Note: As you make your connections, be sure to connect the positive (+) terminals on your amplifier to the positive (+) terminals on your speakers.
Even if your wire does not have (+) or (-) markings, most 2-conductor
speaker wire has printing on one side to help you differentiate between the wire pairs.

Using Bare Wire

1. Use your thumb and finger to unscrew the binding post connectors on the back of each speaker.

2. Insert each speaker wire into the holes on the side of the binding post connectors, observing proper polarity.
   

3. Retighten the binding posts with your fingers.
   

4. The stripped portion of the wire should be secured firmly in each connector.

5. Make sure that none of the speaker wire strands have come in contact with an adjoining terminal.

6. Repeat steps 1 and 5 to connect speaker wires to the amplifier.
   

Step 3 – Connecting the Power Supply
Be sure that the volume/power switch on the front panel is in the OFF position by rotating it counterclockwise until you hear a click.

Connect the cable with the round end from the power supply to the N22 rear panel power connector. Note that this connector is “keyed” so line up the arrow on the cable end with the arrow on the rear panel. Please do not use excessive force on the connector and use only the power supply provided with the amplifier.

Connect the AC power cable from the power supply to a power outlet and verify that the indicator light on the power supply is illuminated. We recommend using a high-quality surge suppressor and/or AC line filter on all electronics equipment.

Step 4 – Connecting Audio Sources
Using the appropriate audio cable (3.5″ mini-jack and/or RCA cable), connect your audio source (computer, iPod, etc.) to the N22 audio inputs.
One of each cable type is included with your amplifier.

Step 5 – Operation
Turn on the N22 volume/power knob and set the volume control to an initial setting of about 3 o’clock. The front panel power indicator will be illuminated.
Turn on your audio input source and adjust the volume to your desired listening level.

Note that 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. We recommend using the volume control on each audio source to adjust the overall system volume.

Other Features

Headphone Out – For headphone enthusiasts the N22 includes a high performance, low-noise headphone amplifier which works well with all types of headphones. Even if you don’t connect speakers to your N22 the headphone amplifier will make your iPod or computer sound better through headphones. Keep in mind that permanent hearing loss may occur if earbuds or headphones are used at high volume so be sure to set the volume to a safe level.

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.

USB Power – The USB power port allows you to charge and power your iPod, iPhone, Audioengine wireless adapters or any other USB powered product through the USB connector on the rear panel. Note that this is for power only, not USB audio or data transfer.

Cleaning

We don’t recommend using any solvents or cleaners on Audioengine amplifiers, cabinets, or speakers. Just wipe down with a soft, dry cloth.

Troubleshooting

Power supply indicator is not illuminated|

• Check to see that the AC power cord is securely connected to the power supply and to an AC power outlet.
• Check that the AC power outlet is supplying power.

---|---
No Sound|

• Recheck speaker wire connections from the amplifier to each speaker.
• Verify that the amplifier and your source components are turned on.
• Check that the AC wall outlet is on and working.
• Check that the cable from the power supply is connected to the N22 and the power supply indicator is lit.
• Check that the volume/power knob on the front panel is turned on and not set to minimum volume.
• Check that your audio sources (iPod, computer, etc) are turned on and not set to minimum volume.
• Check that the cables from your audio sources are working and are properly connected.

Sound through one speaker only|

• Recheck all speaker wire connections on the speakers and the amplifier.
• Check that the cables from your audio sources to the amplifier are properly connected.
• If using a computer, verify that the audio output balance setting is centered.

Lack of bass or poor imaging|

• Check the polarity of the speaker wires on the amplifier and both speakers.
• Check the EQ or sound settings on your audio source.

Sound Distorted|

• Decrease the volume of the input audio source and increase the volume of the amplifier.

Hum

Adding a new component such as your N22 amplifier can bring out hum or buzz that may not have existed before. Your first assumption may be that something is wrong with the component but this is generally caused by a “ground-loop” in your system. Consider these tips for possible solutions:

• First try moving all components to the same electrical circuit or AC outlet.
• If the hum or buzz is still present, power off all gear and remove the mini-jack and/or RCA audio cables to and from the N22 amplifier.
• Turn the N22 back on and check for hum. If the noise is still audible try plugging the N22 power cable into a different AC outlet.
• If the hum goes away while the audio cables are still disconnected, the noise is likely coming from another component in your system. Connect each component back one at a time and the one that causes the system to hum is likely the culprit.
• A common ground-loop source is from cable TV or satellite cables. If the hum or buzz persists after trying the previous tips, disconnect the coaxial cable from your cable box, TV, or DVR and if the hum goes away the cable is the cause. In this case you can get a ground-loop isolator from your local electronics store. These are inexpensive and easy to connect inline with your video cable.
• Sometimes something as simple as a portable heater or dehumidifier will add noise into your wall wiring that could be picked up by your audio gear. A dimmer switch on a halogen lamp, a wireless internet router, or wireless phone near the amplifier, for example, could also all be possible culprits.

The best overall solutions are to use an AC line filter, plug the unit into a different AC circuit, or in the case of noise introduced by a wireless router, for example, move it further away from your audio gear.
