Connecting CorneredInstallation guide
1. Connect the cable
2. Find the perfect spot
3. Mount the speakers
2 Connect the power cable
Note: Istall the power cable and optional line cable BEFORE mounting the
speakers to wall or ceiling! It is not possible to connect the power and line level
cables once the speakers have been installed.
•Install the power cable into the power socket in the rear of the cabinet
•The A3 allows you to connect a wired source in addition to the
Bluetooth connection. The speaker will automatically mix between the
inputs, giving the wired connection priority. So if bluetooth is
connected and the wired connection (a TV or like) is active, Bluetooth
will be disabled. When the sired connection is turned off, BT will be
enabled agian.

Getting started
A3 is an installable active speaker with
Bluetooth 5.0. Follow 3 easy steps to install
your new CORNERED speaker and soon you’ll
be cornered by sound in a class of its own:

The cable will come out in the middle of the front
• Connectto the Phoenix plug with left, right and ground as shown in

PlacementInstallation guide
• 3. Mount the speakers
The C3 is simply installed by screwing through the cabinet
• Remove the front cover (you’ll see the two mounting
holes above and below the speaker units)
• Place speakers in desired position
• Mark drilling positions on the wall by shading through the
2 mounting holes
• Drill holes in the wall and use 4mm rawlplugs and the
enclosed 3mm screws and washers.
• Reposition the speakers in desired position and mount
the screws
• Reinstall the front cover
Operation
Turn on the power by pushing the round switch in the top of the
cabinet. A blue LED light will come on and a voice will confirm
"Power on". Push again to power off.
Connect to Bluetooth by activating BT on your device, Search for
"CORNERED A3" and connect. A voice will confirm "Connected".
If you wish to send a BT signal from another device, disconnect (a
voice will confirm "Disconnected") and connect from the other
device. The Cornered A3 will automatically reset any BT
connection when powered off.

• The Line input will override BT when active
• The tube allows for cables with a maximum diameter of 10mm
•When connecting a passive speaker use speaker cables with a
wire thickness of min. 1,5mm2
• If the red amplifier output is connected to the black speaker input
(out of phase), the stereo imaging will be blurred, and the bass
output will be dramatically reduced
Important note:

Mounting in corners that are not exactly 90 degrees
Even if the corners in your home are not exactly 90 degrees, you can still mount your
new CORNERED speakers in the corner.
• Ifthecornerislessthan90degrees,simplyplacethespeakercabinetasdeepin
the corner as possible. This will leave a little space behind the cabinet and the
walls, but the speakers will still appear with a nice finish in the corner
• Ifthecornerismorethan90degrees,justmountthespeakercabinetontothe
side wall – and leave some air behind the rear of the cabnet. This will not be
visible from the front, and the speakers will still present themselves with a nice
finish in the corner

Daily use of your
speakers
Cleaning and maintenance
To keep up the good looks, clean the cabinet with a soft, dry micro-fiber cloth. The
front cover can be vacuumed and wiped carefully with a well-wrung, lint-free cloth
with a mild all-purpose cleaner. If you need to clean the speakers behind the front
cover, avoid wiping the dome tweeter as it can change the geometry of the dome and
reduce the sound quality significantly.
Disposing of electrical appliances
When eventually disposing of the product, do not mix it with general household waste.
There is a separate collection system for used electronic products in accordance with
legislation that requires proper treatment, recovery and recycling. Private households
in the EU member states, Switzerland and Norway may return their used electronic
productsfreeofchargetodesignatedcollectionfacilitiesortoaretailer(ifyoupur-
chase a similar new one). For countries not mentioned above, please contact your
local authorities for the correct method of disposal. By doing so, you will ensure that
your disposed product undergoes the necessary treatment, recovery and recycling
and thus prevent potential negative effects on the environment and human health.

Installation
Before installing
As CORNERED top-boxes are very light, make sure that the wall structure is solid and
can support the weight of the speaker before installing the speaker. Also, make sure
that you comply with all local health and safety regulations.
A one-person job
The low weight allows the products to be installed easily by one person. Drive units
aspeaker out and Phoenix input can be easily accessed behind the front cover,
which can be removed without tools in a matter of seconds.
Safety wire
In installation terms, the CORNERED top-boxes are ‘as much brackets as they
are speakers,’ so no safety wire is needed, just as you don’t need a safety wire
from the wall to a bracket.
Coverage
Wide dispersion even at high frequencies
CORNERED speakers are designed with emphasis on uniform and wide power
re-sponse. Special emphasis is placed on phase through the crossover point and
cone/dome geometry. As an example, the large surround of the tweeter dome
ensures very wide dispersion also at high frequencies.
