Preparing Your Loudspeakers

The Mission LX-3, LX-4 and LX-S floorstanding models require fitting with the included plinth and 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.
Preparing the Floorstanding Loudspeakers (LX-3, LX-4, LX-5)

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

Conventional Loudspeaker Connections
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 strand together.

Terminal Panels & Connecting The Loudspeakers
Mission LX loudspeakers use a twin terminal connection panel. Only LX-2+ use a four terminal panel which can be bi-wired for improved performance. The HF terminals connect to the treble section of the speaker and the LF terminals to the bass. As supplied,  the treble and bass terminal pairs are connected via removable metal straps. These should be removed for bi- wiring installations.

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-3, LX-4 and LX-5 loudspeakers should be placed on the floor (ideally on spikes). Mission LX-1 and LX-2 LX-2+ should be mounted on rigid stands, ideally spike coupled to the floor.
Height is important: A stand should plate 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 300mmfrom 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 LX-C centre loudspeakers should be positioned ontop of the TV monitor or on a shelf in a console below the TV set. If you place the unit directly on top of the TV, ensure that the cabinet can stand the weight and the assembly is stable. Place the stand on a  stable surface and place the LX-C on the stand. Ensure the stand is central to the speaker cabinet. Check your TV handbook or consult your TV dealer if you are in any doubt.
The surround speakers should be placed above head height and 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. Do not operate them within 450mm of a TV screen.

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 round. 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 LX-C 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 next to walls etc.
Place a bung in each speaker port and adjust them in and out as needed.

5.1 System connections
The front left and front right channels are bi-wired to provide the best fidelity.

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’. With the exception of the LX-1 and LX-2, LX-2+ all the loudspeakers should set to ‘Small’.  Depending on the performance of your subwoofer you may set the LX-3 to ‘Large’ or ‘Small’.

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.

A/V Processor Connections
Your subwoofer has been designed for optimum performance with a digital processor. If your A/V processor has a line level or LFE subwoofer output you should use this connection. You will need to purchase a single screened RCA phono lead from your dealer. Connect this lead to the LFE input of the subwoofer as shown.
Alternatively, you may use a split mono lead from the processor to Line Inputs of the subwoofer.
In this case the input level at the subwoofer will be slightly higher.

Stereo Line Output Connections
If your amplifier has a spare preamplifer output or a stereo subwoofer output, connect the subwoofer as shown. You will need a stereo screened RCA phono cable.

Pre Out – Main in Connections
If you use a stereo pre and power amplifier, or an amplifier where the pre and main amplifier cab be separated, connect the subwoofer as shown. There are two alternative methods.
You will need two screened RCA ‘Y’ adaptors and two single RCA phono cables.
Remove the Pre-Main links on your amplifier. Connect the socket (common) of an RCA ‘Y’ adaptor to the Left Channel Pre Out socket on the amplifier and the other leg to the Left Channel Main In socket. Connect the remaining plug on this combination to the  Left Channel Line Level input on the subwoofer. Repeat this for the Right Channel.

OPERATING YOUR SUBWOOFER

Check that all connections to the subwoofer have been properly made and that the main volume control is at minimum. Plug the supplied power cord into the mains socket on the rear panel.

Initial Settings
Volume Control: Set the subwoofer volume control to the minimum before proceeding.
Crossover Control: Adjust frequency to integrate LX-l0SUB subwoofer with your system requirement.
Phase Switch: The Phase switch should be initially set to 0°.

Switching On
Plug in the mains plug and switch the power on. Now switch the subwoofer on with the rest of your system.
When switched on, the power indicator light will glow and the subwoofer will be operational.

Basic Tuning
Volume Setting: Play a programme with extended bass and set the system volume to a resonal level. Adjust the subwoofer volume control to produce the desired level of bass. The bass should be even and an extension of the main loudspeakers. Do not set the  control too high or you will swamp the sound with too much bass and clarity and definition will suffer.

Phase Switch: If the bass is indistinct or lacks depth, the Phase switch may need adjustment. Set the switch to 0° and listen carefully to some music with extended bass. If there is insufficient bass output from the subwoofer set the Phase switch to 180°. Select the  position which produces the most natural, extended bass.
Crossover Adjustment: This adjusts the blend between the subwoofer and the main speakers and enables the system to be set up for optimum bass performance. The higher settings are for use with small bookshelf loudspeakers, the lower setting for large  floorstanding models. If you choose too low a setting with small speakers, there will be a ‘hole’ in the bass response; too high a setting with large speakers will result in the upper bass becoming bloated. Again the subwoofer should be an extension of the main loudspeakers.
Auto-Sense Switch: This feature reduces the power consumption when there is no music signal. When the Auto-Sense Switch is on, the amplifier will be activated immediately once an audio signal is detected at the inputs, and it will turn into the mute status  when no signal is detected for about 20 minutes, which lowers the power consumption. This feature can be made invalid by setting this switch to off.

Mains Operation
When the system is not in use for extended periods, we suggest you switch off the subwoofer to protect it from switching noises caused by domestic appliances, etc. The best practice is to switch the complete system on and off from a central point. Bear in mind  that if you play the system with the subwoofer switched off you will get no bass!
Always turn the main volume control to minimum when you switch the system on or off.

Loudspeaker Maintenance
Use a cloth to clean your cabinets and very occasionally, a slightly dampened cloth to remove finger marks etc.
Although the grilles may be removed. these speakers have been voiced to sound at their best with the grilles on.
We do not advocate removal of the grilles: if necessary clean grilles carefully in place with a soft brush.

Service Centre
Should a fault occur with your loudspeakers, please pack it correctly, using the original packing, so you can ship it safely. Product for service should be returned to the appointed dealer from whom you purchased the product. If you experience difficulties or there  is no mission dealer in your area, contact the Mission distributor or the office below.
