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 ZX-3, ZX-4 and ZX-5 floor standing 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 Floor standing Loudspeakers (ZX-3, ZX-4, ZX-5)

Attention:

Because the product is heavy, please arrange 1 or 2 persons to remove package.

1. Prepare a piece of towel or carpet as protection cussion.
2. Open the carton from the top , Put the carton upside down on the towel or carpet.
3. Remove the outside carton and the inside pack.
4. Put the product straight up and place it in the right place.

Spike Seats
A set of spike seats is provided to protect sensitive floors from possible damage. The loudspeaker should be mounted on the wide spikes and the spike seats should be placed under each spike as shown. Level the loudspeakers with the spike seats in place.

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 models in the Mission ZX 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 ZX-3, ZX-4 and ZX-5 loudspeakers should be placed on the floor (ideally on spikes). Mission ZX-1 and ZX-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 300mm 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 ZX-C1/C2 centre loudspeakers should be positioned on top 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 ZX-C1/C2 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 ZX-S 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.

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.

Positioning Surround Loudspeakers

ZX-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.

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 ZX-1 and ZX-2 all the loudspeakers should set to ‘Large’. Depending on the performance of your subwoofer you may set the ZX-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.
