Welcome to Mission!
Bi-Wiring & Bi-Amping
The 77 Series is the latest in a long line of distinguished Mission loudspeakers. These technologically advanced loudspeakers will compliment the finest electronics and décor. Patented Aerogel membrane bass drivers and advanced neodymium tweeters are used throughout the range. A critically tuned suspension ring mechanically de-couples the tweeter housing from the rest of the cabinet. High-purity nickel-plated binding posts feature on all models.
Mission models 772 – 775 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 below, the terminal panel on the left is bi-wired; the panel on the right is conventionally wired. Note the shorting links.
Your Mission 77 Series loudspeaker system will bring you great listening pleasure for many years.

General Information Please read these instructions carefully before installing your loudspeakers. A few minutes studying this manual will ensure superb performance from your loudspeakers for many years. Please pay attention to all cautions printed on the pages marked with this symbol ..........................................
Unpacking Your Loudspeakers • • •
Remove all the staples and sealing tape from the carton. Carefully unpack each loudspeaker. Retain all the packing materials so that your loudspeaker can be repacked and shipped without damage.
Fitting Spikes – Models 773 - 775 Refer to Fig.1 and 2 on the fold out page. • • • • •
Invert the loudspeaker and place the top on a soft surface. Screw a nut on each spike and place a washer over the nut. Screw the spikes into the bushes fitted in the base of the cabinet. Carefully return the loudspeaker to its normal position. Adjust the height by screwing in or out one or more of the spikes until the loudspeaker is stable and level.
An outrider is provided for additional stability. To fit this unit: • • •
Place the outrider over the rear of the cabinet base. With the screws supplied, attach the outrider securely to the rear mounting bushes in the cabinet. Now attach the rear spikes to the bushes on the outrider. Install the front spikes and complete the installation as above.
Connecting Your Loudspeakers Terminal Panels Your loudspeakers use two or four terminals. When connecting a four-terminal panel conventionally, ensure that the shorting links are installed as shown.

Conventional Loudspeaker Connections
By using separate amplifiers for LF and HF drive units you can further improve performance. This is known as bi-amping. The illustration opposite shows one channel of a bi-amped system. Note that the amplifier inputs are linked.

Positioning Your Loudspeakers Refer to Fig 3. on the fold-out page. Mission 773, 774 and 775 loudspeakers should be placed on the floor (ideally on spikes). Mission 771 and 772 should be mounted on rigid stands, such as Mission ‘Stance’, ideally spike coupled to the floor. Height is important: A stand should place a loudspeaker’s tweeters at ear level to a seated listener. Shelf or bracket mounting is second best. The distance from the rear wall can profoundly affect loudspeakers’ sonic performance. If your speakers are too close to the wall the bass will boom and sound coloured. Moving them into the room may increase clarity but tends to reduce bass output. When positioned correctly, the high frequency response is smooth with well-defined, powerful bass. Start with the speakers about 20cm from the wall and 1.8 metres apart. The distance from each loudspeaker to the side wall should be at least 0.5 metres. Vary the distance between the two loudspeakers and the distance from the wall until you get a perfect stereo stage. A few minutes optimising you’re listening position will be rewarded with a soundstage limited only by the quality of your equipment.
Phase To check that your loudspeakers are in phase, check the polarity of your speaker wire at the terminal post on the loudspeakers and at the loudspeaker connector on your amplifier. The marked conductor should always be connected to the positive terminals.
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 together.
If your loudspeakers are wired correctly, the sound should be full with clean treble and a deep, rich bass.
Unscrew each terminal. Thread the bare end of the cable through the cross-hole ensuring there are no loose strands. Tighten securely.
Your loudspeaker cables have a noticeable effect on sound quality. After extensive research, Mission has developed Duet and Quartet, cables for standard and bi-wiring applications. Additionally, MISSION and CYRUS amplification provides outstanding fidelity with wide system dynamics and will optimise the performance of your loudspeakers.
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.

The Mission 77C Centre Channel Speaker
Product Service
The Mission 77C has been designed to reproduce dialogue in a Home Cinema installation. It is magnetically shielded and may be placed close to a TV set without causing interference.
Should a fault occur with your loudspeakers please return them as a pair, even if only one unit appears to be faulty. Please pack them correctly, using the original packing. 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 for your country or the Main Service Centre for your region. A list of the principal Mission Service Centres is at the rear of this instruction manual.
Attaching the Feet Peel off the backing paper. Firmly attach each foot about 25mm in from the corner of the base of the loudspeaker cabinet. Connections and Phasing Your Centre Channel loudspeaker must be connected to the Centre loudspeaker terminals of your AV amplifier or receiver. Follow the instructions in the previous sections for connections.
Setting up Audio Visual Loudspeakers Fig. 3 on the fold out page shows a typical AV set-up. Placement Your Centre loudspeaker will normally be sited on top of the TV monitor, or on a shelf in a console below the TV set. If you are placing the loudspeaker on top of the TV monitor, ensure that the monitor cabinet can stand the weight and that the assembly is stable. Some manufacturers forbid the placing of objects on top of their TV sets. Check your TV handbook before installing the 77 Series Centre speaker directly on your TV set. Consult your TV dealer if you are in any doubt. Sound Level It is important that the centre, front and rear speakers are set to the same sound level as perceived from the listening position. Follow your AV processor handbook instructions carefully, especially the section concerned with setting up relative loudspeaker levels.
Loudspeaker Maintenance Periodically tighten the fixings on the bass drivers to keep them secure. DO NOT touch high frequency drive unit fixings. Use a slightly dampened cloth to clean your cabinets and occasionally, a light spray polish to protect their sheen. Remove grilles before brushing them carefully with a soft brush.
