A BRIEF INTRODUCTION TO HOME THX

Incorporating a series of patented electronic and
loudspeaker developments, home THX is the ultimate in
sound for multi-channel home cinema systems. The system
was developed after it was realised that conventional audio
components could not satisfactorily reproduce movie
soundtracks in the home environment.

As well as more accurately reproducing the highly complex
and competing sound fields present in multi channel
soundtracks, home THX successfully adjusts audible tonal
and spatial anomalies. These are caused by the reproduction
of movie soundtracks, that are really designed for playback
in cinemas, in the more compact home environment.

THX Select was developed specifically for the smaller room,
calibrated to define reference level performance in
environments of about 2000 cu. ft.

THX Select gives you full confidence that each certified
component will perform as “the best in it’s class”.

GETTING STARTED

Connecting your MS500 THX Select System

Please do not compromise the performance of your system by using infe­rior quality cables. Mordaunt-Short recommends that high quality cables
of 16 gauge or higher be used. Your professional dealer will give you
good advice.

There are two pairs of terminals on the rear of every speaker which
permit bi-wiring if desired. For standard (non bi-wire) cable connection,
leave links in place and use either pair of terminals (fig. 1).

fig. 1

Observing polarity is of the utmost importance while connecting your
loudspeakers. Ensure that the red (+) terminals on your amplification
system are connected to the red (+) on the speaker, and black (-) on
your amplification system to black (-) on your speakers.

If your speakers are wired incorrectly they will be out of phase and sound
hollow and indistinct, with a weak bass. Re-check your connections for
correct polarity and reverse the connections if necessary

Bi-wiring sends the bass and treble frequencies down separate speaker
cables, resulting in a clearer, more focused sound. To bi-wire each speaker
loosen the upper pair of terminals and allow the binding post links to
disconnect (fig. 2). Use two runs of cable, or specific bi-wire cable,
between the amplifier and each pair of terminals

Important note

Always unplug all A.C. powered components before making any loud­speaker or component connections. This will avoid the risk of electric
shock or damage to your equipment.
