EXPERIENCE THE NORDIC SOUND

Experience the Nordic Sound
In the middle of Sweden right next to lake Hjälmaren lies Örebro. It is known for
its live music scene, rich nature and beautiful city centre with the majestic castle
towering the many restaurants and the buzzing night life. This is where we design
and engineer Dynavoice.
The Dynavoice logo is a seal of quality. It guarantees that what you now have in
your possession comes from a passion for music and sound with you, the listener,
in focus.
Through our different products you will discover ’the Nordic Sound’, a warm and
powerful, yet detailed and natural sound that over the years has become synony-
mous with Dynavoice.
We want you to discover new details in your favourite songs, and experience new
dimensions when you re-watch your favourite movies with a Dynavoice
multichannel sound system. We love what we do, and we want you to hear and
feel our passion and dedication through our speakers.
Thank you for choosing Dynavoice, and enjoy listening to the Nordic Sound.

Unpacking
When you unpack your new Dynavoice speaker, please do it with care. In case the product involves
heavy lifting or if it is too big for one person to handle – make sure to have assistance, we do not
want you to break the product or yourself.
When life happens and you move to a new home, you will want to take your Dynavoice products
with you. The easiest way to do this is in the original packaging so if possible - keep the box and the
packing material.
The box contains:
Before you start
This amplifier is designed to be matched with a pair of Dynavoice floor standing speakers or book-
shelf speakers (please consult your local Dynavoice dealer for information regarding matching
speaker models with your amplifier). It is important that you do not block any ventilation or place
the amplifier inside any small, non-vented spaces. All other instructions regarding hazardous
placement can be found in the Important Safety Information.
Your amplifier has been tested at our factory before being sealed up inside the packaging, even so
we recommend you to go easy in the beginning. Make sure that everything was included in the box
and that you have made the right connections before turning on the amplifier.
The remote control requires 2x AAA batteries, make sure that there are no obstructions between
the amplifier and the remote signal.
The included Bluetooth antenna needs to be fixed in place, more about this can be found further
on in this manual.
Always make sure that your amplifier is turned off when you connect your speakers. Dis-
regarding this advice may cause a sudden audio spike that can permanently damage your
speakers.
To get the best experience possible from your new Dynavoice amplifier we recommend you to use
high quality cables throughout your entire system.

Connecting your amplifier
Below you will find some examples on how to connect your speakers to your new Dynavoice ampli-
fier. These are some basic type of connections, please consult your local Dynavoice dealer if you
feel unsure.
Single-wiring
The standard way to connect your speaker is following the positive (+) and negative (-) markings on
the speaker to your amplifier creating a single-wiring connection. This connection is necessary on
the models with a single connector terminal, and optional on a model with a bi-wiring terminal.
When you use a single-wiring connection with a bi-wiring terminal, keep the shorting bars in place.
