Mission 77 Series Loudspeakers User Instructions

Welcome to Mission!

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.

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.

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

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 strands together.

Bi-Wiring & Bi-Amping

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.

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.

If your loudspeakers are wired correctly, the sound should be full with

clean treble and a deep, rich bass.

Ancillary Equipment

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.

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.

Unscrew each 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

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.

Please pay attention to all cautions printed on the
