MartinLogan Depth [16/24] Home theater

It had long been the practice of stereo buffs to connect

their television to the stereo system. The advantage was the

use of the larger speakers and more powerful amplifier of the

stereo system. Even though the sound was greatly improved,

it was still mono and limited by the broadcast signal.

In the late 1970's and early ‘80's two new home movie formats

became widely available to the public: VCR and laser disc.

At the same time video screen sizes began increasing.

By 1985, both formats had developed into very high quality

audio/video sources. In fact, the sonic performance of some

video formats exceeded audio-only formats. Now, with

theater quality sound available at home, the only element

missing was the "surround sound" presentation found in

movie houses.

Fortunately, "Dolby" and "DTS" encoded material (which

include almost all movies) have the same surround sound

information encoded on home releases as the theater films.

All that is required to retrieve this information is a decoder,

additional speakers, subwoofer(s) and amps to reproduce it.

Home theater is a complex purchase and we recommend

that you consult your local MartinLogan dealer, who is well

versed in this subject.

Each piece of a surround system can be purchased sepa-

rately. Take your time and buy quality. No one has ever

complained that the movie was too real. The following list

and descriptions will only give you a brief outline of the

responsibilities and demands placed on each speaker.

Front Left and Front Right

If these speakers will also be the same two used for your stereo

playback then they should be of very high quality and able to

play loud (over 102 dB) and reproduce bass below 80 Hz.

Center Channel

Many experts believe this to be the most important speaker

in a home theater system, as almost all of the dialogue and a

large portion of the front speaker information is reproduced

by the center channel. It is important that the same manu-

facturer of the front speakers design the center speaker and

that it is recommended for use as a center speaker. This is

not the place to cut corners.

Surround Speakers

We recommend that the surround speakers play down to

70hz. The surround, or effect speakers contain critical infor-

mation. In films, sound effects are vital to the director in

delivering a complete experience and the rapid technical

increase in the discreet capacity of these effects channels has

made their quality vital. This is equally true in music play

back because of the emerging high definition, multi-channel

music only formats. Full range instruments, voices and ambi-

ent queues are being routed to the effects channel. In the

past, some may have suggested that this was the place to

save money by purchasing small inexpensive speakers. If you

choose to do so, be prepared to upgrade in the future.

Subwoofer

With any good surround system you will need one or more

high quality subwoofers (the .1, in a 5.1 channel surround

system). Most movie soundtracks contain large amounts of

bass information as part of the special effects. Good sub-

woofers will provide a foundation for the rest of the system.
