Definitive Technology DI55R Speaker System User Manual


 
Your Mythos STs have a set of speaker level (high level) 5-way binding posts
and in addition, each speaker has an LFE input. This input can be used with Dolby
Digital* and DTS* 5.1 (6.1, 7.1) decoders to separately feed the discrete “Low
Frequency Effects” channel into each subwoofer (which then combines with
the low bass present separately in the left or right channel signals). Unlike a
conventional system, where the subwoofer is driven only by an LFE subwoofer
signal, the Mythos STs are much more sophisticated and are driven by the left or
Your Mythos STs should sound good right out of the box; however, an extended
break-in period of 40-60 hours or more of normal playing is required to reach full
performance capability. Break-in allows the suspensions to work in and results in
fuller bass, a more open “blossoming” midrange and smoother high frequency
reproduction.

a sonic point of view. Speakers may be angled in toward the listening position
or left parallel with each other. Angling the speakers in (pointed directly at the
listener) will result in a somewhat brighter, clearer sound with a sharper focus
and a more solid central image (generally, we recommend this), while leaving
the speakers parallel with each other will result in a less bright, warmer sound.
Positioning Mythos ST as Rear/Side Surrounds
When used as rear or side surround speakers, Mythos ST may be located on
the side or behind the listeners. When used on the sides, take care never to locate
the speakers forward of the listeners. If the speakers are placed on the rear wall,
it is suggested that they be positioned fairly wide apart if possible. (For instance,
if there is a couch in the center of the rear wall on which the listeners will sit,
try to position the speakers wider apart than the couch.)
An optional “spiking” kit has been provided should you desire to “spike” your
loudspeakers. “Spiking” your loudspeakers will provide much greater stability
when placing your loudspeakers on carpeting. It will also, according to many
experts, result in an overall improvement in sonic performance. Care should be
taken when using spikes as they may cause damage to wooden or other floors
which are susceptible to being scratched. Definitive Technology is specifically not
responsible for damage which may result from the use of spikes.
The spike kit contains five spikes. To install, unscrew the non-marking tips
from the centers of the five leveling feet and screw the five spikes in their places.
Then, with the help of another person, lift the speaker upright and lower it to
