if you are unsure of your ability to provide a secure and safe fixing. You will need to
determine where to fit the bracket and the structure of the wall. If unsure, please
obtain the services of a competent qualified trades-person.

WARNING: Ensure that there are no water pipes, or electricity cables running
behind where the wall bracket is going to be secured. Work from secure steps
and avoid trailing wires.

Re-cycling

Correct Disposal of Waste Electrical and Electronic Equipment (WEEE) by User in Private
Households in the EU.

This symbol on the product or accessories indicates that they must not be
disposed of with your household wastes throughout the EU. To prevent
possible harm to the environment or human health from uncontrolled
waste disposal, recycle it responsibly to promote the sustainable reuse of
material resources. Instead it is your responsibility to dispose of your waste

Setting up and Positioning

Although position and suitability will have been considered prior to purchasing your
Radius

HD

, this section will guide you through the optimum positioning and setting up of your
loudspeakers. An illustration is provided on page 6 to assist you in ensuring your speakers
are placed in the optimum positions. For instructions on fitting your RadiusHD speakers
to a wall, please go to pages 7,8 & 9. Self adhesive rubber feet are provided to prevent
movement due to vibration when using the RadiusHD on a table/ equipment stand. The
R270HD comes supplied with rubber feet fitted into the plinth. Further details on these can
be found on page 10.

R one

HD

This cabinet simply needs to be placed either just below or just above your TV/ projector
screen. Ideally, it should be angled towards your listening position.

Positioning - Front Speakers

With the centre channel the tweeter is best pointed towards the listener’s ears to help direct
the sound and should be the first speaker you place in your home theatre room. The centre
channel’s job is to anchor dialogue and other on-screen sounds to the screen. Typically, As
much as 60% of a movie soundtrack comes through the centre channel .

The centre channel can be placed either above or below your TV screen, and as close as
possible. If positioned in a cabinet or sitting on top of the TV ensure that the front edge
is aligned with the front edge of the TV or shelf. Where possible, the height of the centre
channel’s tweeter should be close to the height of your front speakers’ tweeter — ideally,
within about 600mm.

When placing your Radius

HD

loudspeakers on the wall, around a plasma/ LCD TV, the left
and right speakers need to be between 22 & 30° to the left and right of the seating position,
with the tweeters at approximate ear level.

Positioning - Surround Speakers

Ideally, your primary pair of surround speakers should be placed to the left and right of
your listening position — either in line with it, or just behind it (90 - 110°). If you have a 6.1
channel or 7.1 channel system with more than two surround speakers, or if side placement
isn’t available in a 5.1 channel system, consider placement behind your listening position,
facing the front of the room (135 - 150°).

Surround speakers should be placed high enough so that the drivers do not fire directly at
your ears when you’re sitting down — one rule of thumb is to place them at ear level while
standing. If your surround speakers fire directly at your ears, they can overpower your front
speakers.

If your surrounds are mounted on the side walls on brackets (R45

HD

& R90HD), experiment
with aiming them. You may get good results from pointing them at the ceiling or toward the
rear corners of the room.

Surround speaker placement which is ideal for home theatre may not necessarily be perfect
for multichannel music listening, where a precisely focused rear soundstage is best. If both
types of listening are important to you, then you can position your surround speakers for a
compromise between the two.

Introduction

Congratulations and thank you for your purchase of the RadiusHD loudspeakers. We are
confident they will provide years of enjoyment and pleasure as only high quality components
have been used throughout.

Building on the overwhelming success of the original Radius Series, Radius

HD

brings
redesigned cabinet profiles, enhanced cabinet structure, improved aesthetics and improved
sonic balance and response.

The R270

HD

has received major performance enhancements in every area. We have
increased the cabinet volume, added an additional rear firing port and also added ballast
in the bottom of the cabinet. All of these new features combined to offer improved, tighter,
punchier bass response and extra cabinet stability.

The R45

HD

and R90HD come supplied with a wall fixing bracket. This enable upto 18 degrees

of movement in all directions.

We have also introduced a new product to the Radius

HD

Series, the R oneHD. The R oneHD
is a left, centre, right in one cabinet. Each channel is enhanced with it’s own braced
compartment and individually specified crossovers. Designed to fit below/ above your
TV where the centre channel would normally sit, additional left and right speakers are not
needed as the R oneHD houses all three in one.

Please follow this user manual carefully as it contains important information about positioning
and set up procedures. For further advanced information on system set-up, FAQ’s and
multi-lingual support please refer to our web site at: www.monitoraudio.co.uk

The R45

HD

has a thermal protection device in it. This helps to protect the drive unit
and tweeter from permanent damage. If the speaker stops working after a long
period of play, turn off the source for about 10 minutes, and retry.
