Sound  field  simulation

The  surround  processes  already  described  require
programme  material  which  is  encoded  using  the
appropriate  system,  but  the 

DD 1535 R 

also  offers  a

facility  to  enhance  the  spatial  effect  available  with
conventional unencoded stereo recordings (CD, MC, FM
radio etc.).

These 

sound  field  simulations

  are  based  on  an

accurate  analysis  of  the  room  acoustics  of  a  number  of
popular room and hall types.

The digital signal processor of your decoder is capable of
simulating  and  reproducing  the  characteristic  sound  of
these venues.

For  example,  if  you  select  the 

HALL

  setting  while

watching  a  rock  concert  on  television,  you  will  have  the
illusion of sitting in the middle of the audience.

Please  note  that  it  is  important  to  set  the  sound  field
which  is  appropriate  for  the  material  to  which  you  are
currently  listening.  It  makes  no  sense  at  all  to  select  a
sports  stadium  if  you  intend  listening  to  a  concert  of
chamber  music,  or  an  intimate  club  atmosphere  for  a
rock concert.

Your 

DD 1535 R 

can generate the following sound fields:

 Disco 

This  sound  field  is  particularly  suitable  for  providing  an
even  spread  of  sound  over  a  dance  area.  The  sound
signal  is  reproduced  with  equal  power  by  the  main  and
surround  loudspeakers,  without  echo  or  delay.  The
strongly  concentrated  sound  produced  in  this  way
generates  an  immediate,  energy-charged  atmosphere
which is a great choice for any party.

Note:

With the Dolby Digital EX / DTS ES decoder the signal is
also reproduced by the centre and back speakers.

 Hall 

A  resonant  concert  hall  with  reflections  from  all
directions. Ideal for reproducing a large orchestra, or the
live atmosphere of a large rock concert hall - an excellent
choice for highly dynamic rock music.

 Opera 

This  program  combines  the  complete  spectrum  of  clear
voice reproduction with the full sound reproduction of an
orchestra,  without  any  unnatural  echo.  For  better
orientation  the  room  sound  is  restricted  slightly  towards
the rear.

 Arena 

Sound image with a narrow presence in the front region.
Commentators  and  dialogues  are  localised  on  the
screen.  The  rear  resonance  provides  the  impression  of
the public in the stadium. This sound field is also suitable
for TV shows and music transmissions.

 Club 

The  characteristic  cellar  jazz  club  atmosphere,  with  a
pattern  of  sound  reflection  which  is  dominated  by  large
floor  and  wall  surfaces.  Also  good  for  simulating  small
halls.

 Church 

Simulation  of  the  acoustic  conditions  of  a  large  church
with  a  long  resonant  period.  This  sound  field  is  the
perfect choice for sacred organ music.

 MCH-IN 

If  the  MCH-IN  input  is  assigned  to  the  active  source.  In
this  case  the  sound  signal  of  the  Multi-channel  input  is
used.
