Introduction
Welcome to the Audioengine family and congratulations on
your purchase of the A2+ Premium Powered Desktop Speakers.
The Audioengine team is dedicated to bringing you the highest
quality listening experience possible and the A2+ is designed
with the same attention to detail and operational simplicity
as other Audioengine products. Our goal is to get you to your
music as simply as possible without all the“gadget tinkering”
that other products generally require. As with our other past
eorts, we thank all our customers and resellers for helping us
create another great Audioengine product!
Unpacking
Your Audioengine speakers were carefully tested and inspected
before packaging and shipping. After unpacking please
check for any damage. It is rare that a unit is damaged during
shipping, but if this does happen contact the shipping company
immediately. We recommend that you keep the original carton
and packing material for any possible future shipping.

Cleaning
Your A2+ speakers are designed for years of use with no
maintenance as long as you avoid exposure of the speakers to
moisture or high temperatures. The hand-nished MDF wood
cabinets are very durable and are easily cleaned by wiping down
with a soft, dry cloth. We do not recommend using cleaners or
solvents.

Placement
Place your Audioengine 2+ speakers at a comfortable listening
location with no obstructions at the front or back. If you nd
that raising them to an angle produces the best sound, this is
easily achieved by adding the DS1 Desktop Stands (available
separately).
We recommend at least 3 inches of clearance around the back of
the cabinet for good air circulation.

1. Use your thumb and nger to unscrew the connectors.
2. Insert each speaker wire into the holes on the side of
connectors.
3. Retighten the connectors with your ngers.
4. The bare portion of the wire should be secured rmly in each
connector.
Repeat the procedure to connect the other end of the speaker
wire to the other speaker. Check to make sure none of the
speaker wire strands have come in contact with a nearby
connector.
As the A2+ speakers have the power ampliers built inside, do
not connect the speaker terminals to the speaker outputs of a
stereo receiver.

Step 4 - Enjoying your Speakers
1. Turn on the rear panel volume/power knob and set the
volume control to about 3 o’clock.
2. Turn on your audio source and adjust the volume to your
desired listening level.
Two audio sources may be connected to the speakers at the
same time. To adjust the volume, we recommend using the
individual volume controls on each source.
We recommend using a high-quality surge suppressor and/or AC
line lter on all electronics equipment.
Basic Troubleshooting
If the LED indicator on the power supply is not illuminated:
- Check to see that the power cord is securely connected to the
power supply and to an AC power outlet.
- Check that the AC power outlet is supplying power.
If the speakers do not produce sound:
- Check that the cable from the power supply is connected to
the rear panel, and that the LED indicator on the power supply is
illuminated.
- Check that the volume/power knob on the rear panel is not set
to minimum volume or powered o (we recommend at least a
10 o’clock position).
- Check that the volume level of your audio source in not set to
minimum or powered o.
- Check that the wire from your audio source to your speakers
is properly connected (occasionally the 1/8” cable feels as if it is
inserted all the way, but is not).
If the speakers produce sound from the left speaker but not the
right:
- Check that the speaker wires are correctly connected between
the left and right speaker connectors.
- Check that the cable from your audio source to the speakers is

A2+ setup guide
12 13
properly connected.
If the sound is distorted:
- Decrease the volume of the input audio source and increase the
volume of the speakers.
