Quickstart Guide

N22 Quick Setup

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, ve-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.

If you are 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 lter 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.

Troubleshooting

N22 Troubleshooting Tips

The following troubleshooting tips can help diagnose and correct most concerns with the N22. We have attempted to make this list as comprehensive as possible. So, even though some of these may not apply to your issue, please still go through each one.

If the power indicator LED on the N22's external power supply unit is not on, then try these tips:

  1. Connect the AC power cord to the power supply unit and to a working AC power outlet.
  2. Plug the cable at the other end of the power supply into the rear of the N22.

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

  1. Verify that the volume/power control on the front panel is not all the way down or off.
  2. Ensure that your audio source is on and that the volume level is not too low.
  3. Check speaker wire connections from the amp to the speakers by removing the speaker wire from each speaker and then reconnecting. Also check the speaker wire polarity by verifying that the wires are going to same terminals on both speakers.
  4. Unplug and reconnect the cable(s) from your audio source(s) to the amplifier.
  5. Try decreasing the volume of the input audio source and increase the volume of the N22 amp.
  6. Try using different audio input sources and/or devices to see if the problem follows.
  7. Listen with headphones if possible to see if the issue is present there as well.
  8. Try swapping your left and right speaker to see if the issue remains in the same channel or if it follows the speaker.
  9. When using the N22 with a computer, make sure the volume is up on your media player, internet radio, master control, device volume, etc. and that the balance control is centered.
  10. If you are using a wireless adapter, preamp, or an external DAC with your N22, remove these (temporarily) and connect the audio source directly to the speakers.
  11. If your input source has its own EQ (equalizer), please make sure the low end is at a moderate level. Too much bass in your signal can cause some unwanted distortion.
  12. Move your N22 and 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 nearby can cause interference.

FAQ's

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!
