Planning your system

When installing your Opus multi-room entertainment system, consideration
should be given to detailed advance planning. We strongly suggest you
read this entire manual before commencing any work.

MCU300 A-BUS®Master Control Unit

The MCU300 is located alongside source components which means you
have two MCU300 location options:

1. Locate MCU300 and source components in any convenient discreet
location with adequate ventilation within the home (such as an under­stair cupboard, service room or cabinet), or...

2. If it is desired to use the same sources for the Opus system as are being
used by a conventional stereo or surround sound system it is possible
to route source equipment through the MCU300 for output through
existing hi-fi or home cinema amplifiers whilst also distributing them to
the rest of your home via the Opus system.

Should this be required, your existing audio source equipment
would be first connected to the MCU300 and then routed from the six loop
out sockets on the MCU300 to the amplifier/receiver in your system via
high quality audio interconnect cable terminated at each end by
phono/RCA plugs.

Similarly video source equipment may be connected to the VSU300 and
then routed from the six loop out sockets on the VSU300 to the A V receiver
in a home cinema setup using phono/RCA cables designed for video use.

For this configuration the MCU300 should be located behind your existing
system.

The MCU300 is compact and can be mounted either horizontally, or
vertically, such as on a wall, and is powered by a dedicated power supply
(Opus PSU).

Try to ensure that the MCU300 and it’s source components are powered
from the same set of mains outlets.

It is suggested that you locate keypads:

• 138cm height from the floor finish (to
centre of keypad) or taking into
account light switch locations etc

• 25-35cm away from the outer edge of
any door frame or wall edge

• Away from direct, bright sunlight which
may affect infra-red performance

MCU300 location is
critical. See opposite
for details.

In a bedroom it is suggested that you
locate speakers above or close to bed
location for optimal stereo reproduction.

Locate speakers in all
rooms taking into
account location of
furnishings for optimal
stereo reproduction.

VSU300 Video Switching Unit

The VSU300 video hub works in conjunction with the MCU300 to provide
video signals to all connected zones, via 75 Ohm video cabling
(RG6/CT100 co-axial cabling can be used). Up to six video input sources
and a CCTV input may be connected and distributed, with their
corresponding audio signals routed through the MCU300 as one of its
dedicated six inputs.

The VSU300 may be mounted either horizontally or vertically in the same
manner as the MCU300, and power is provided by the MCU300 via a Cat­5e patch cable, so no extra power supply or mains socket is required.

When deciding upon a location for the MCU300 and VSU300 units
consideration should be given to space constraints, and power points for
the source equipment and MCU300, as well as integration into any existing
setups.

WCU300 A-BUS®Wall Control Unit

Simple and intuitive control is provided by the WCU300 A-BUS keypad.
Housed in a stylishly designed casing, the WCU300 fits into any wall and

is available with different finishes to compliment various decorative
schemes. Control of your source equipment, volume, bass, treble and other
functions can be performed by the WCU300.

Each WCU300 may be used as a main zone or sub-zone controller , with the
only difference being that the sub-zone must listen to/watch the same
source as the main zone.

Should extra amplification or an active subwoofer be required (to provide
more bass), a line level pre-amp output is provided on the back of the
WCU300.

AMR650 / OS165CC in-ceiling speakers

When placing the ceiling-mounted 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.

It is advisable to plan all aspects of installation in advance of work
beginning, preferably with the house/flat building schematics if available.

CCTV system connection

It is possible to connect a CCTV camera to your multi-room system. Refer
to the section on ‘Advanced system options’ for details. Please note that
extra cabling will be required in addition to that explained in the installation
notes.

Wiring to zones

Run a Cat-5e cable from the MCU300 to each wall control unit.
Fit a single-gang back box for each WCU300.
Run two standard speaker cables from the WCU300 to mounted

loudspeakers. If video is required, run 75 Ohm video cable (CT100/RG6
high-quality co-axial cable) from the VSU300 main zone connection either
directly to the video display, or to a wall-mounted panel fitted with a
suitable phono/RCA connector.

Cabling tips

Cat-5e cable should be run through the installation in electrical conduit,
either metal, non-metallic, rigid or intermediate, wherever possible. Should
conduit not be available or impractical, cabling running through frames or
beams must be a minimum of 25mm/1inch from the nearest edge of that
structure. If the frame or beam is metallic, then the cable should be
protected by a bush or grommet.

When routing cables around the installation, care must be taken to prevent
kinking and trapping. Any cable ties used must not be tightened any more
than is necessary to hold the cable in place.

Always re-check the colour code of the Cat-5e cable connections to ensure
they are correct.

Pre-installation notes

Please read these notes before commencing installation.

MCU300 A-BUS Wall Control Unit

A-BUS is a standard that allows some compatibility between different
manufacturers A-BUS multi-room products. The MCU300 can be switched
between Opus A-BUS or Standard A-BUS mode. The Opus A-BUS
position is for use with our own Opus WCU300 keypad and gives extra
functions. When used with other manufacturers A-BUS keypads it should
be set to Standard A-BUS or they will not work. The switch is located on
the rear of the MCU300 (see below).

Fix to a hard surface such as a cupboard surface, not to carpet or a soft­lined surface, as this will inhibit airflow through the unit. Do not situate in
close proximity to any installation which will produce excessive electrical
noise such as dimmer racks etc (these may interfere with the unit). Situate
within three metres of a power socket.

VSU300 Video Switching Unit (where specified)

Locate in close proximity to the MCU300 (maximum of five metres away).
Fix to a hard surface such as a cupboard surface, not to carpet or a soft­lined surface, as this will inhibit airflow through the unit.

Do not situate in close proximity to any installation which will produce
excessive electrical noise such as dimmer racks etc; these may interfere
with the unit.

Pre-installation notes continued

AMR650 / OS165CC in-ceiling speakers

Standard installation would specify AMR650/OS165CC ceiling mounted
speakers which are matched to the Opus 300 system for optimum audio
performance. However , virtually any customer -specified speaker units may
be used.

Where ceiling or wall-mounted speakers are used, care should be taken to
ensure that all building regulations are followed.

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 pairs of AMR650/OS165CC speakers.

When deciding upon a ceiling or wall 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, so that the
target area can be moved to a more suitable position.

Also, locate loudspeakers taking into account location of furnishings for
optimal stereo reproduction.

Full details of installation, connection, operation and special features can
be found in the guide that accompanies the speakers.

Sub-zone connections

One MCU300 hub supports four main-zones and four sub-zones (eight
rooms in total). Each sub-zone output is tied to a main zone output and
always receives the same source as its main zone (A2 sub-zone output
always receives the same source as A1, B2 always follows B1 etc).

Sub-zones are used for instances such as en-suite bathrooms (the
bedroom being a main zone) where it is desired to to have an area that
automatically follows the same source as another but can be independently
turned on and off, has individual bass and treble etc.

Any main zone can have a sub-zone.

Advanced system options

Note: Full details of installation, connection, operation and special features
can be found in the guide that accompanies the LIM300 module.

The LIM300 Local Input Module (LIM) is an optional in-wall module that
allows the user to add additional local sources to those distributed by the
MCU300.

The local source may only be heard in the room where it is connected and
the corresponding sub-zone (if connected) and is not distributed to other
rooms. LIM300s can be fitted in as many rooms as are desired.

The LIM300 connects between the MCU300 audio hub and a WCU300
keypad using Cat-5/5e wiring. Each main zone can support two LIM300s,
giving you the option of listening to one or two local sources (eg.
Playstation, MP3 player). Each local source can be controlled through the
Opus remote and/or keypad.

Note: The MCU300 and WCU300s must be in Opus A-BUS mode in order
to use an LIM300.

Note: If you are running a sub-zone, this must always be wired via the
LIM300 in the same way as the main zone.

Connecting an external amplifier/active subwoofer to your
system

Should extra amplification power, or, an active subwoofer be required, a
line level pre-amp output is provided on the back of the WCU300.

Using high-quality audio interconnect cable, an external power amplifier
may be connected to the WCU300 pre-amp output screw terminals.

A fader function on the WCU300 can be used to adjust the level between
the speakers connected to the WCU300 and the external amplifier/active
subwoofer, so that the balance between the two can be adjusted.

CCTV

A CCTV system may be connected to the Opus 300 Multi-Room system.
Connect the monitor/TV video signal output to the VSU300 at the CCTV IN

socket located on the top surface of the unit allowing the live video feed to
be viewed in all connected zones.

If sound is also required, the audio signal output of the CCTV system may
be connected to the EXT/CCTV inputs on the MCU300.

If the CCTV system is to be remote controlled connect an IR-1 infra-red
emitter to the ALL COMMANDS output on the MCU300 and stick the

Linking units

For large installations which require more than four main zones and four
sub-zones, an MCU300 ‘linking’ facility is provided. Units are linked via a
Cat-5e patch cable to the ‘Hub Link’ in and out sockets on the top right
hand corner of each MCU300.

In order to share audio input sources with the first MCU300, the second
may be joined using Opus C39 audio couplers (see diagram). These
double-ended phono plugs simply connect the ‘Loop out’ sockets of the
first MCU300, to the ‘Audio input’ sockets of the second, allowing both to
access the same sources and distribute them to all available zones.

Up to four MCU300s may be linked together in this way, pr oviding audio for
a maximum of 16 main zones for the MCU300, or 16 main zones and 16
sub-zones for the MCU300.

VSU300 linking

Should video also be required in more than the four main zones and four
sub-zones provided by the VSU300, then these units may also be linked.
Each VSU300 must be connected to a corresponding MCU300 via the Cat­5e patch cable, in order to provide power and switching commands.

Video input sources may then be shared between both VSU300 units by
using Opus C39 couplers (see diagram). These double-ended phono plugs
simply connect the ‘Loop out’ sockets of the first VSU300 to the ‘Video
input’ sockets of the second, allowing both to access the same sources
and distribute them to all available zones.

Up to four VSU300s may be linked together with the corresponding four
MCU300s in this way, pr oviding video for a maximum of 16 main zones for

FAQs

1. What entertainment equipment can I connect?

The Opus 300 system is compatible with almost any type of hi-fi or video
separate.

2. What is the difference between a main zone and a sub­zone?

A sub-zone can only listen to the same audio source as is being listened
to in the main zone. The sub-zone has independent power, volume and
tone controls from the main zone.

3. How many rooms can a system serve?

Each MCU300 supports 4 main + 4 sub-zones. 4 MCU's can be chained
together supporting up to a maximum of 16 main zones and 16 sub­zones. If a larger system is required it is possible to have two or more
separate systems running independently giving unlimited expandability.

4. Can I use any Cat-5e cable?

Any type of Cat-5e can be used.

5. Do I have to use Opus speakers?

No, but it is highly recommended as the Opus speakers are optimised
and impedance matched to the keypad amplifiers.

6. How many remote controls can the system have?

There is no limit to the amount of remotes you can have. If required you
can have a remote in each room.

7. What advice can you give for keypad location?

When locating a keypad you should avoid putting in direct sunlight or in
close proximity to Plasma screens. Care should also be taken locating it
near to devices that produce electrical noise such as mechanical
dimmers. Positions of other wall controls/light switches should also be
considered.

8. Is there a maximum cable run from MCU to each WCU?

Yes, the maximum cable run is 30 metres / 100 feet.
