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
practically 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.
Connecting to a sound source
Check that your amplifier/sound processor/receiver is
switched off before connecting Muso. Failure to do this
may result in both speaker and amplifier damage.
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) terminals on
Muso. Similarly, connect the negative terminal of the
amplifier (normally coloured black or labelled with
‘–’) to the black (negative) terminals on Muso.
After connecting
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.
Rubber mat
We recommend you sit the Muso speaker on the
rubber mat supplied. The mat fits inside the recessed
area of the speaker base and provides a stable, non-slip
surface that helps to acoustically decouple the speaker
from its support.
Detachable speaker cover
Although the metal front grille is effectively acoustically
transparent, some users prefer speakers with an ‘open’
appearance. The cover is secured by four magnets and
can be easily detached and replaced.
In removing the cover (and during storage), be careful
not to bend or twist the grille as it is a precise fit with
the speaker. The tweeter unit has a metal guard to
protect it, but take care not to damage either drive unit,
or place any object in the port opening.
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.
If the Muso speakers are to be shelf-mounted,
remember to sit the speaker on the rubber speaker mat
supplied
.
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.
