1. Take heed of warnings and instructions
You should read all the safety and operating instructions before using this speaker. Retain
this handbook for future reference and adhere to all warnings in the handbook or on the
speaker.
2. Climate
The speaker has been designed for use in moderate climates.
3. Speaker placement
The speaker is designed for placing on a stand or wall bracket. It should be sited where
speaker leads do not cause a trip hazard.
4. Cleaning
The cabinet should normally only require a wipe with a soft, damp, lint-free cloth. Do not
use paint thinners or other chemical solvents for cleaning. We do not advise the use of
furniture cleaning sprays or polishes.

Welcome…
… and thank you for purchasing the Arcam Muso loudspeakers.
The Muso speakers are a compact design that use very high quality materials
throughout. The speakers have been designed to produce a stunningly accurate,
powerful and musical performance in a compact and elegantly understated cabinet.
We hope that your Muso speakers will give you years of trouble-free operation. In the
unlikely event of any fault, or if you simply require further information about Arcam
products, our network of dealers will be happy to help you. Further information can
be found on the Arcam website at www.arcam.co.uk.

Connecting to a sound source
Make sure that your amplifier/sound processor/receiver is switched off before connecting
the Muso speakers. Refer to your amplifier/receiver/sound processor handbook to identify
the speaker terminals and their polarity. For each speaker, connect the positive terminal of
the amplifier (normally coloured red or labelled with '+' to the red (positive) terminal on
the Muso. Similarly, connect the negative terminal of the amplifier (normally coloured black
or labelled with '-') to the black (negative) terminal on the Muso.
Turn the sound source amplifier volume down to minimum before switching on. Switch
the amplifier(s) on, select a source signal, then gradually increase the volume to the
required listening level.
Interconnect cables
We recommend the use of high-quality audio interconnect cables to ensure the best
performance of your system. All cables should be kept as short as possible. It is good
practice to make sure that any mains power supply cabling is kept as far away as possible
from your audio cables, to eliminate unwanted noise in the audio signals.

Speaker positioning: stereo
For optimum results, these speakers should be placed on rigid stands or wall brackets close
to the rear wall and at least 60cm from any side wall. As an alternative, these speakers may
be placed on a shelf or bookshelf, but the shelf must be of solid construction. The Muso
speakers should never be placed on the floor; or in corners.
The Muso speakers will give best results with the tweeters (the smaller of the two speaker
cones) at, or just below, ear height when the listener is seated.
The final sound will, of course, depend on the acoustics of the listening room, and
experimentation with speaker positioning and furnishings is definitely worthwhile. As a
starting point, we suggest that the speakers should be placed 2-3 metres apart with their
back 10-30 cm away from the wall. The bass output may then be increased or decreased
by moving the speakers closer to or away from the wall. Turning-in the speakers, so that
their axes cross just in front of the listener, may also improve the treble balance and stereo
imagery in some situations.

Speaker positioning: 5.1
The advice given here is a general guideline for setting up speakers. For useful information
on listening room layouts see:
www.dolby.com/us/en/guide/surround-sound-speaker-setup/index.html.
Room acoustics
Your room’s shape and how it is
furnished will affect the sound you
hear. For instance, too many bare
surfaces can cause reflections that
may add harshness to the sound.
Carpets, wall-hangings and curtains
can all help.
If you have a choice of listening
rooms, avoid one that is perfectly
square or has one dimension exactly
twice another. Such a room can
aggravate resonances that colour the
sound.
The closer you place a speaker to
corners and the intersection of wall and floor or wall and ceiling, the stronger the bass
output, which may over-emphasise the bass. Moving a speaker just a few inches can
sometimes make a big difference.
Speaker setup
Proper speaker placement is the key to the best home theatre sound (see diagram).
As a rough guide, speakers should be placed on rigid stands at about 10–30cm from the
rear wall and at least 60cm from any side wall. Speakers should never be placed on the
floor (unless they are floor standing speakers), or in corners. The speaker drivers should be
at, or a little above, ear level when seated. If possible, centre your seating area between the
surround speakers.
The final sound will depend on the acoustics of the listening room and experimenting with
speaker positioning is very worthwhile.
Subwoofer
The location of the subwoofer (Low Frequency Effects speaker) will affect the overall sound
quality. Placing the subwoofer next to a wall or in a corner will often boost efficiency and
give a cleaner low bass sound. However, all rooms react differently and we recommend
that you experiment with subwoofer positioning.

Care of your speakers
Running-in
In the same way as a new car requires a‘running-in’period, so do all loudspeakers. Your
Muso speaker may sound good when you first connect it, but with time it will improve
dramatically Expect about 50 hours use before the full potential of your Muso is realised.
Power handling
Arcam speakers are designed to reproduce recorded music under normal domestic
conditions. We do not recommend nor warrant them for commercial applications, such as
discothèques, public address, etc.
Bearing this in mind, these speakers will perform well and safely with hi-fi amplifiers rated
between 20 and 100 watts per channel. Care must be taken, however, to avoid amplifier
overload or‘clipping’. Apart from possible damage to the amplifier, this can (and does)
damage loudspeakers. In this respect, an overdriven low-powered amplifier is more likely
to cause damage than a properly used high-powered one.
Speaker stands/wall brackets
The more firmly a speaker is held, the better it will sound.
This is best achieved by using sturdy, metal, speaker stands or wall brackets. In the
case of stands, properly damped types that do not‘ring’when tapped with a pencil are
recommended. It is helpful to have stands with adjustable spikes or spacers to eliminate
rocking movements in the speakers. Suitable speaker stands or wall brackets are available
from your Arcam dealer.
Cleaning
To clean your speakers use a soft, slightly dampened cloth to wipe off any dust or dirt. Do
not use solvent-based or chemical cleaning products as these may damage the finish of
the speaker cabinet.
