PACKAGING CONTENTS

The Opus AMR650 V2.0 is an A-BUS™ compatible ceiling­mounted speaker pair for use where an installer wishes to avoid the
complication of a separate keypad and speakers. It uses the
Octopus MCU300 as the hub or connects to an Opus sub-zone
output etc.

The AMR650 V2.0 consists of one active speaker with a stereo
power amplifier and other electronics built-in (AMR650-A ); and one
passive speaker (AMR650-P).

Please take the time to read this guide fully as it contains important
information and should be retained for future reference.

INTRODUCTION

AMR650-A

AMR650-P

Your speakers are an example of superior design and
craftsmanship. These suggestions will help you care for them so
you can enjoy them for years.

Keep the speakers dry. If they get wet dry immediately. Liquids can
contain minerals that can corrode electronic components.

Keep the speakers away from dust or dirt, which can cause
premature wear of parts.

Wipe the speaker frame occasionally with a damp cloth to keep it
looking new. Do not use harsh chemicals, cleaning solvents or
strong detergents.

CARE AND MAINTENANCE

4

It is advisable to plan all aspects of installation in advance of work
beginning, preferably with the house/flat building schematics if
available. Great care should be taken to ensure that all building
regulations are followed. When deciding upon a ceiling placement,
care should be taken to avoid joists, load bearing beams etc

Before cutting ceiling loudspeaker holes it is suggested that the
area is tested for clearance by making an L-shaped probe from
strong wire (eg a coat hanger), drilling a small hole in the target
area, inserting the probe and slowly turning. Any obstructions will
be immediately obvious, and the target area can be moved to a
more suitable position.

When placing the AMR650 V2.0 speakers, thought should be given
to positions which give the best desired sound coverage
throughout a room, while not interfering with existing or planned
light fittings or joists. Also, locate loudspeakers taking into account
location of furnishings for optimal stereo reproduction.

When mounting speakers flush to a ceiling or wall, ensure that
enough depth/clearance is available in the respective cavity. A
clearance of at least 80mm is necessary when mounting an
AMR650 V2.0.

Remove the round cardboard pad from inside the supplied
template (see below). Use the template to mark the position for the
mounting hole at the selected location. Cut the mounting hole with
a drywall or keyhole saw.

1. Remove the grille by inserting a small hook or similar small
implement into one of the grille openings, then pulling on the
grille. For the AMR650-A, carefully disconnect the IR connector
lead before proceeding.

2. Fit the clear plastic painting mask provided when painting the
speaker surround to avoid getting paint getting on the speaker
cone.

3. Spray-painting the grille will prevent blocking the grille holes with
paint. For the AMR650-A unscrew the IR window assembly
before spray painting. Do not paint the silver IR window on the
AMR650-A Active speaker. If you do not wish to not paint the
silver badge on the AMR650-P Passive speaker, cover with
masking tape.

After the paint dries, remove the paint mask and replace the grille.

Adjusting the CN17 and CN14 jumpers together switches the
speaker between some stereo and mono modes. Two mono modes
are available, see page 10 for further details.

123

No current function.

The AMR650-A has six ‘Push-on Jumpers’ (shown below - see
opposite for PCB location) that select between different modes of
operation. Incorrect positioning will prevent the AMR650 V2.0 from
working properly.

Fader

Turns Fader function on and off. See page 11 for futher details.

Local

Switches between LIM300 local and AMR650 V2.0 onboard option.
See page 10 for further details.

Opus/A-BUS

Swtiches between Opus Enhanced mode for use with Octopus
hubs, and normal A-BUS mode.

For use with an Octopus MCU300 A-BUS hub the jumper MUST be
in the OPUS position. For use with standard A-BUS hubs and
amplifiers from other manufacturers (or as a sub-zone to a MCU500
based system) the jumper MUST be in the A-BUS position.

Gather pairs, trim and carefully

insert into RJ45 plug:

Crimp wires in place using a

professional quality crimping tool

to ensure a secure connection:

1. Using a single Cat5e cable, connect the AMR650-A to the
MCU300 via an RJ45 plug at the Master Control Unit, and the 8­way colour-coded punch down connection at the AMR650-A.

The RJ45 hub connection should be wired to EIA/TIA568A
standard as shown.
The Cat5 connection from MCU to the AMR650-A should not
exceed 30 metres/100 feet.

2. The AMR650-A is then connected to the AMR650-P using either
Cat5e cable terminated at 8-way colour-coded punch down
connections (all 8 cores must be connected) or using a run of
standard speaker cable.

Only one method of connection between the active and passive
speaker is necessary.

Note: Use a professional quality punch down tool to ensure secure

punch down connections.

1. Before mounting, ensure that the four fixing screws are
slackened off so that the red mounting dog-legs can move freely.

2. Move each red dog-leg foot to the LEFT into it’s holding slot, and
then insert the speaker into the mounting hole.

3. Using a cross-head screwdriver, slowly turn each fixing screw
clockwise. This will move the mounting dog-legs out of their
slots.

4. Tighten each fixing screw until the mounting dog-legs grip the
ceiling.

MOUNTING THE AMR650 V2.0

Stereo/Mono mode

The default mode for the AMR650-A is stereo, but there are two optional
mono modes:

1. Mono 1 Mode (1 channel mono)

In instances where it is desired to fit only one speaker (ie in a small room
such as a bathroom), the AM650-A (active) speaker can be set to mono
mode, and the AM650-P (passive) speaker not used. The active speaker
then reproduces both left and right signals combined. Starting from the
default jumper positions on the AMR650-A, the CN17 jumper stays on the
RIGHT end pins and the CN14 jumper moves to the LEFT end pins - see
page 7.

2. Mono 2 Mode (2 channel mono)

In instances where two speakers will be installed but due to physical
placement stereo imaging will not work effectively (ie in an L-shaped room
or corridor etc), the speaker pair can be set to mono mode. The speakers
then both reproduce left and right signals combined. Starting from the
default jumper positions on the AMR650-A, move the CN17 jumper to the
LEFT end pins and the CN14 jumper stays on the RIGHT end pins - see
page 7.

Local Source Input

It is possible to install a piece of source equipment to be used local
to the room that contains the AMR650 V2.0. This might be a games
machine or CD player in the bedroom, for example. The are two
ways of connecting a local source:

1. Octopus LIM300 Wallplate

The LIM300 wallplate has a line input and and IR output socket for
IR control of the local source via the AMR650 V2.0. See dedicated
literature for installation instructions. Local Jumper MUST be set to
left and centre pins - see page 7.

2. AMR650 V2.0 onboard local input

A local source can be connected directly to the AMR650 V2.0. IR
control of the source can only be done ‘line-of-sight’ in this case as
the AMR650 V2.0 does not have an IR output. Connection to the
local input socket on the AMR650-A should be via screened audio
cable, terminated at a suitable faceplate. Local jumper MUST be
set to centre and right pins - see page 7.

ADVANCED FEATURES

11

Preamp Output

A preamp output is provided for optional driving of an auxilary
stereo amplifier or active subwoofer etc. Connection from the
preamp should be by screened audio cable. If utilising the preamp
output facility you may wish to activate the Fader function. This will
allow you to balance the relative output levels between the AMR650
V2.0 and the auxilary component. Move the Fader jumper switch on
the AMR650-A to the the centre and right pins - see page 7.

Independent 24V local power supply

The AMR650 is powered directly from the MCU300 via the Cat5
cable. If your installation has very long cable runs from the MCU300
to the AMR650 V2.0 (greater than 30M) the AMR650 V2.0 must be
locally powered instead. This simply involves plugging an Opus
PSA65U power supply into the local power socket on the AMR650­A.
