IMPORTANT SAFETY INSTRUCTIONS

This symbol indicates that there are important operating and maintenance instructions in the literature accompanying this unit.

Read these instructions. Keep these instructions. Heed all warnings. Follow all instructions.
Before making any connections, switch all the units in your system oﬀ at the mains.
Set the volume control at minimum when you switch on your system or change sources, and turn the level up gradually.
DO NOT use your ampliﬁer at full volume.
Ensure that all loudspeakers in the system are correctly wired.
DO NOT subject your loudspeakers to excessive cold, heat, humidity or sunlight.
Loudspeakers should not be placed directly facing other hi-ﬁ units, or share the same shelf or cabinet.
DO NOT place heavy objects on top of loudspeakers.
Some manufacturers forbid the placing of objects on top of their TV sets. Check your TV handbook before installing the speaker directly on your TV set. Consult your TV dealer if you are in any doubt.
DO NOT connect speaker terminals to the mains supply.
DO NOT dismantle the loudspeaker. There are no user serviceable parts inside it and you will void the warranty by doing so. Refer all servicing to qualiﬁed service personnel. Servicing is required when the apparatus has been damaged in any way, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
Caution: Changes or modiﬁcations not expressly approved by the manufacturer could void the user’s authority to operate this device.
Unpacking Your Loudspeaker
LX MKII Series loudspeakers come in diﬀerent shapes and sizes. If you are unpacking a ﬂoor stander, please remember that these units are heavy. We suggest that you have someone to assist you.
Lift the loudspeaker carefully out of the packing. DO NOT try and lift the loudspeaker using the protective bag. Unpack the accessories carefully.
If there is any sign of damage or if the contents are incomplete, report this to your dealer as soon as possible. Retain the packing for future safe transport of the product. If you dispose of the packing, do so with respect to any recycling provisions in your area.

WARNING: When an ampliﬁer is driven beyond its power output capabilities it will produce output capabilities it will produce distorted results which will quickly damage your speakers by overheating. Make sure that your ampliﬁer is not left unattended when playing, for example at parties, and turn the volume control down at the ﬁrst sign of sudible distortion.

General Information

Please read these instructions carefully before installing your loudspeakers. A few minutes studying this manual will ensure a superb performance from your loudspeaker for many years. Please attention to all cautions printed on the pages marked with this symbol.

Preparing Your Loudspeakers

The Mission LX-4 MKII, LX-5 MKII and LX-6 MKII ﬂoor standing models require ﬁtting with the included spikes before use. Use the screw provided to secure the plinths to the base of the speakers.
Make sure that the screws are fully tightened. After unpacking, the other loudspeakers need no further preparation.
Please remove the foam bungs from the bass port to the rear of the speaker. All LX MKII loudspeakers (except the LX-C1 MKII and C2 MKII) are reﬂex enclosures. The foam bungs are not generally required but they may be used to alter the bass parameters and damp resonances, especially when operating the loudspeakers next to walls etc.
Place a bung in each speaker port and adjust them in and out as needed, if they are required in your listening environment.
We advise retaining the bungs with your original packaging and manual.

Fitting the spikes

Warning: Be careful. Loudspeaker spikes are very sharp. When positioning the speakers avoid piercing any electrical cables.

Invert the loudspeaker and place the top on a soft surface.
Screw a nut on each spike.
Screw the spikes into the bushes ﬁtted in the base of the cabinet. Use the sharp end on carpet, or the domed end on hard ﬂoors.
Carefully return the loudspeaker to its normal position.
Ensure that the spikes do not pierce cables etc. under the carpet.
Adjust the height by screwing in or out one or more of the spikes until the loudspeaker is stable and level

Connecting Your Loudspeakers

Loudspeaker cable is polarity coded along one edge. Split the cable to a depth of about 25mm and strip 8mm of insulation from each wire. If the cable is stranded, twist the strands to make sure that no stray strands contact the opposing terminal. Terminal Panels & Connecting The Loudspeakers

Unscrew the terminal and thread the bare end of the cable through the cross hole ensuring there are no loose strands. Tighten securely.
Connect the red, positive (+) terminal of the left loudspeaker to the corresponding red, positing (+) ampliﬁer terminal. Connect the black, negative (-) terminals similarly. Repeat for all channels accordingly.

Positioning Your Loudspeakers

Floor Standing and Bookshelf Loudspeakers

Mission LX-4 MKII, LX-5 MKII and LX-6 MKII ﬂoor standing loudspeakers should be placed on the ﬂoor (ideally on spikes). Mission LX-1 MKII, LX-2 MKII and LX-3 MKII bookshelf loudspeakers should be mounted on rigid stands, ideally spike coupled to the ﬂoor.
Height is important: A stand should place the top of a speaker at ear level to a seated listener. Shelf or bracket mounting is second best. The distance from the wall can profoundly aﬀect loudspeakers’ sonic performance. If your speakers are too close to the wall the bass will boom and sound will be coloured. Moving them into the room may increase clarity but tends to reduce the bass output
When positioned correctly, the high frequency response is smooth with well-deﬁned, powerful bass. Start with the speakers about 300m from the wall and 1.8m apart. The distance from each loudspeaker to the side wall should be at least 500mm. Vary the distance between the two loudspeakers and the distance from the wall until you get a perfect stereo stage. If your loudspeakers are wired correctly, the sound should be full with a clean treble and a deep, rich bass.

Centre and Surround Speaker

Your centre loudspeakers (LX-C1 MKII and LX-C2 MKII) should be positioned on a shelf above the TV monitor or in a console or stand below the TV set. If you place the unit directly above the TV, ensure that the shelf or support can stand the weight and the assembly is stable. Ensure the loudspeaker is positioned centrally between the left and right speakers and is connected to the centre channel output of your ampliﬁer. Check your ampliﬁer handbook or consult your dealer if you are in any doubt.
If you are using a CRT TV (older style Cathode Ray Tube TV), do not position speakers within 450mm of a TV screen. The surround speakers (LX-3D Surround MKII) should be placed above head height and either to the side or behind the listening seat. They may be stand or bracket mounted on the side walls or on the rear walls but always behind the listener.
LX-3D can also be used in vertical channel home cinema, such as Dolby Atmos and DTS: X systems for the height channels. In this case the LX-3D can be placed on top of the front speakers, with the drive units facing upwards.

Tuning and Phase

Phase: To check the loudspeaker phase, check the polarity of your speaker wire at the terminals of the loudspeakers and at the loudspeaker terminals of the ampliﬁer. The conductor colour should always be connected the same way around. If your loudspeakers are connected correctly, you will hear a full sound with clean midrange and a deep, powerful bass.

Fine Tuning: All the loudspeakers, except the centre loudspeakers (LX-C1 MKII and LX-C2 MKII), are reﬂex enclosures. Although these will not normally be needed, foam port bungs are provided which may be used to alter the bass parameters and damp resonances, especially when operating the loudspeakers close to walls or corners. Place a bung in each speaker port and adjust them in and out as needed. (Note, the foam ﬁlling for the ports in Centre channel speakers should not be removed)

Home Theatre Topics

Loudspeaker Positioning
Front Loudspeakers: The front loudspeakers are placed on either side of the TV monitor, 2 to 3 metres apart. The speakers should be angled slightly so they are aimed towards the listeners.
Rear Surround Channels
We recommend placing the surround speaker in a high position, behind the listeners head. If the rear wall is more than 1 metre behind the listening seat, an alternative position is on the side walls. If the walls are a long way from the listening seat, consider stand mounting the loudspeakers.
Centre Channel
Most of the dialogue comes from the centre loudspeaker. Speech should appear to originate from the actors mouths. Operating height is important. Ideally the front and centre channel speakers should be at the same height. The front of the cabinet should be level with the TV screen.

Setting Speaker Sizes
When used with a subwoofer, digital AV processors usually require you to set the size of the loudspeakers for good bass management. This is usually ‘Large’ or ‘Small’. For the LX-1 MKII, LX-2 MKII, LX-3 MKII, LX-3D MKII, LX-C1 MKII and LX-C2 MKII, these the loudspeakers should set to ‘Small’. Depending on the performance of your subwoofer you may set the LX-4 MKII, LX-5 MKII and LX-6 MKII to ‘Large’ or ‘Small’.
Loudspeaker Maintenance
Use a cloth to clean your cabinet and very occasionally a slightly damped cloth to remove ﬁnger marks, etc. If necessary clean the grilles carefully in place with a soft brush.
