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 QX-3, QX-4 and QX-5 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 (QX-3, QX-4, QX-5)

ATTA CHING THE SPIKES

CAUTION: SPIKES ARE SHARP.
Make sure that there are no wires or hidden obstacles that could be damaged by the spikes in the immediate operational area of the speakers.
NEVER drag a loudspeaker on its spikes. always lift it. lf the item is heavy get assistance.
A mounting hole is located at each corner of the plinth. Thread a spike through each hole.
Tighten the collar finger tight so that the spike is secure but not locked inplace.
After all the spikes are attached, invert the loudspeaker and place it carefully on the floor.

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
Your loudspeakers use two or four terminals. When single wiring speakers use the connecting links as shown opposite.
Unscrew the terminal. 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, positive (+) amplifier terminal. Connect the black, negative (-)  terminals similarly. Repeat for the right channel.

Bi-Wiring
All floorspeaker models in the Mission QX Series can be bi-wired for improved performance.
Remove both pairs of shorting links and connect a cable to each pair of terminals, running them to a common connection at the amplifier output terminals.
In the figure to the right, the terminal panel on the left is bi-wired; the panel on the right is conventionally wired. Note the shorting links.

Bi-Amping
By using separate amplifiers for LF and HF drive units you can further improve performance. This is known as biamping.
Note that the amplifier inputs are linked.

Positioning Your Loudspeakers

Floor Standing and Bookshelf Loudspeakers
Mission QX-3, QX-4 and QX-5 loudspeakers should be placed on the floor (ideally on spikes). Mission QX-1 and QX-2 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 QX-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 QX-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.

Positioning Surround Loudspeakers

QX-S Surround Loudspeakers
The speakers should ideally be sited 600 mm-1.5 metres above the listening position and 2.5-3.5 metres apart, central to the listener and behind the listening position, preferably  on a rear wall. If the listening position is some distance from a rear wall, the speakers may be mounted on opposite side walls but always behind the listening position.
Ensure that the wall is sound and can support the product. Drill two 5mm holes in the wall 180mm apart. Fix a suitable No 8 round head screw firmly into each hole using  appropriate wall plugs. Leave a stub of 5mm protruding from the wall.

Connect the loudspeakers. Align the holes in the mounting brackets over the screw and carefully lower the unit onto the screws.The speaker should now be securely attached  with the spacers resting against the wall. Now connect the speakers to the amplifier.

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 QX-1 and QX-2 all the loudspeakers should set to ‘Large’. Depending on the performance of your subwoofer you may set the QX-3 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. Although the grilles may be removed, these speakers.
have been voiced to sound at their best with grilles on. We do not advocate removal of the grilles: if necessary clean the grilles carefully in place with a soft brush.

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.

CONNECTING THE SUBWOOFER TO THE SYSTEM

Control Panel of the QX-12SUB Subwoofer

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 QX-12SUB 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 oft

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.
