Lexicon Offers LOGIC7 UpMix Software for 960LProprietary algorithm permits upmixing of stereo sources to surround September 5, 2002
On the heels of the 960L Automation package, Lexicon has announced yet another software option: the
LOGIC7 UpMix Option. This new feature is included as standard in 960L's shipping from Lexicon with V4
software. It is also available as an option for all existing 960L's. The V4 software upgrade is free to all registered
960L users and necessary to add the new LOGIC7 option. Contact a Lexicon 960L dealer or Lexicon for more
details.
LOGIC7 is technology -- developed by Lexicon's Dr. David Griesinger -- for creating surround
signals from stereo sources. The
LOGIC7 UpMix Option generates 5-channel surround information from stereo inputs and features a wide front
image with surround channel envelopment. Surround channels are distinct (not monaural) and
maintain the full bandwidth of the stereo source, avoiding the use of simple filtering, which tends to produce an
unstable surround effect.
As in the case of other 960L algorithms, the LOGIC7 Upmix Option is fully configurable. Program elements, rolloff
and surround channel delay can be adjusted, and the sensitivity of the algorithm itself can be altered to suit
stereo source variations. Virtually all parameters are artifact free, allowing them to be used silently while running
the algorithm.
"LOGIC7 has been successful in several environments," remarked Buzz Goodwin, Lexicon's Vice President of
Sales. "It has long been a selling point of our consumer products, and has recently found a new audience through
its application in the OEM automotive market." He went on, "The 960L is designed to operate in surround
environments, and with an increasing amount of older material -- sometimes limited in spatial content -- being
remixed for surround release, LOGIC7 can be the key to bringing these recordings back to life
