MartinLogan Dynamo 500 [11/18] Heater

It had long been the practice of stereo buffs to connect their

television to a 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1980’stwonewhome

movie formats became widely available to the public:

VCRandlaserdisc.

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DVD’semerged

with the same surround sound information encoded on

home releases as the theatrical release. Additionally,

new high-resolution home-viewing formats such as Blu-ray

as well as high-definition content provided via cable or

satellite have evolved which include multi-channel encod-

edaudiothatisvirtuallymastertapequality.Allthatis

requiredtoretrievethisinformationisadecoderandaddi-

tional speakers and amps to reproduce it.

that you consult your local MartinLogan dealer, as they

are 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 give you only a brief outline of the

responsibilities and demands placed on each speaker.

Front Left and Front Right

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

playback,theyshouldbeofveryhighqualityandabletoplay

loudly(over102dB)andreproducebassbelow80Hz.

Center Channel

This is the most important speaker in a home theater

system, as almost all of the dialogue and a large por-

tion of the front speaker information is reproduced by the

center channel. It is important that the center speaker

beextremely accurateandmatewell withthefront

speaker, and that it is recommended for use as a center

speaker. This is not the place to cut corners.

Surround Speakers

Werecommend(alongwiththefilmindustry)thatthesur-

roundspeakersplaydowntoatleast80Hz.Surround

speakers contain the information that makes it appear that

planes are flying over your head. Some may suggest that

thisistheplacetosavemoneyandpurchasesmall,inex-

pensive speakers. If you choose to do so, be prepared

to upgrade in the future as discrete multi-channel digital

encoding is proliferating rapidly and the demands on sur-

round speakers have increased.

Subwoofer

large amounts of bass information as part of the special

effects. Good subwoofers will provide a foundation for the

rest of the system.
