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 discothesiques, 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.

speaker positioning: stereo

For optimum results these speakers should be placed on rigid stands or wall brackets close to a 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. 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 - 30cm from the rear wall. The bass output may then be increased or decreased by moving the speakers closer to or further 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.

The metal protective grille attached to the Muso speaker is acoustically transparent, so the speaker may be used with the grille on or off, as desired. If the speaker grille is removed, please remember that the drive units are exposed and can be easily damaged by inquisitive young fingers.

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/consumer/home_entertainment/roomlayout.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, car 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
