SRS Labs' TruBass(TM) Technology Licensed By Hitachi For World's First 32-Inch HDTV-Ready Plasma TV

SRS' TruBass Selected by Hitachi to Produce Rich,

Bass Performance for World's First 32-Inch Plasma TVs



Apr 04, 2001, 01:00 ET from SRS Labs, Inc.

    SANTA ANA, Calif., April 4 /PRNewswire/ -- SRS Labs, Inc. (Nasdaq: SRSL),
 a leading provider of innovative audio and voice technology solutions, today
 announced that Hitachi, Ltd. (NYSE:   HIT) has licensed the Company's
 proprietary TruBass(TM) technology and is featuring the technology in the
 world's first HDTV 32-inch plasma TVs.  TruBass will enable Hitachi customers
 to benefit from rich bass sound for home theater enjoyment through the
 television's small speaker system which is only 9-centimeters deep.  Normally,
 such small speakers could not reproduce these low frequencies.  By adding the
 patent-pending TruBass enhancement technology, Hitachi's television can
 utilize harmonics contained in the original sound signals received to deliver
 much deeper tones to the listener.
     Hitachi has been using SRS technologies in products since 1996 and will
 release its first model with TruBass in this new HDTV series, W32-PD2100, in
 Japan on April 10th and a second model with a built-in BS (Broadcast
 Satellite) digital receiver on June 11th.  The monitor units used in the
 plasma TVs developed for the Japanese market have been designed for worldwide
 use.  Looking to the future, Hitachi intends on using the European market as a
 launching pad for plasma TVs.
     Hitachi's goal was to develop a 32-inch HDTV PDP, small enough for home
 use, which could also handle the high resolution of BS digital HDTV
 broadcasts, which started last year.  SRS Labs' TruBass allows the speaker
 size to remain small while producing a big bass sound.  The W32-PD2100 TV is
 the first in the series.  Hitachi is also planning to introduce a 37-inch HDTV
 plasma TV.  Hitachi expects to continue to expand its lineup of PDP-based TV
 products to meet the needs of the new era of digital HDTV broadcasting.
     "SRS Labs' TruBass technology is a key feature in our television
 products," said Mr. Ikuo Yuki, General Manager, Hitachi, Ltd.  "Our customers
 can now enjoy deep, rich bass though our slim plasma televisions.  TruBass
 gives us a design advantage that allows us more flexibility in our product
 design and increases our audio reproduction quality.  We no longer require
 large enclosures or large speakers to reproduce low bass tones."
 
     About TruBass(TM) Technology
     TruBass(TM) is a remarkable audio enhancement technology from SRS Labs
 that provides deep, rich bass to small speaker systems without the need for a
 subwoofer or additional physical components.  TruBass circuitry actively
 monitors the low-frequency content of an audio signal and optimizes the
 frequency and amplitude spectrum of the output signal to enhance bass
 perception.  The theory is based on the pipe organ theory that in summary
 states that one can use two harmonics contained in the original sound source,
 add them together and the listener will hear a lower bass tones that normally
 could not be physically reproduced by the speaker.  Therefore, this technology
 does not "over drive" speakers or push them beyond their physical limitations,
 eliminating any chance for distortion.
