Operation
OPERATION
1. Press the Power button 1 on the
front panel to turn the unit on.
• To use the remote for power on/off it is
necessary to turn the unit on from the
front panel switch and to leave the switch
in the “on” position. The PT2500 may
then be turned off using the
Power but-
ton b on the remote. When the remote
is used to turn the unit “off” it is actually
placing the system in a standby mode, as
indicated by the amber color of the power
switch ring.

extended period of time it is always a
good idea to completely turn the unit off
using the front panel

or VDP the video signal for that input

MONITOR output
jacks ‹ and will be viewable on a TV
monitor connected to the PT2500. Make
certain that your TV set is set to the prop-
er “VIDEO” input to view the signal.

boost low and high frequency sounds to

Fletcher-Munson hearing curve).
Surround Mode Options
Surround sound processing enables four
separate audio signals to be transmitted
within the left and right channels of a
videocassette, radio or TV broadcast, or
video disc. Through a process known as
matrix encoding a separate center chan-
nel signal for dialog and a surround
channel for effects are encoded into the
stereo signal. When you see the Dolby
Surround
™ , Dolby Stereo ™ , DTS Stereo ™
or other similar logos on a movie or
broadcast this indicates that the program
has surround information.
When the program you are listening to
has encoded surround information, as
shown by one of the logos or brand
names described above, select the
ProLogic mode using the front panel or
remote Surround Mode Selectors
6h .
If a center channel speaker is used along
with front left/right speakers, but no sur-
round speakers are used, choose the
Dolby 3 Stereo mode 6h . This
combines the surround signal into the
front left and right channels to create a
greater feeling of presence and a more
expansive sound field than with conven-
tional stereo signals. Center channel dia-
log information will continue to be
heard through its proper place at center
screen.
When listening to conventional stereo
recordings or programs, those with sepa-
rate left and right channels but no inten-
tionally recorded surround information,
you may wish to experiment with the
surround modes to see which produces
the effect you prefer. Stereo recordings
often contain sufficient natural phase
differences so that the ProLogic or
Dolby 3 Stereo Modes are enjoyable,
despite the lack of true surround infor-
mation.
Stereo recordings may also sound more
expansive in either the
Theater or
Stadium modes. Selecting these modes
6h uses the front left and right
speakers for normal stereo, while the sur-
round speakers are fed a reverberated
sound. In order to provide for a wider
variety of sound field effects, the sur-
round channel delay available in the
Theater and Stadium modes is substan-
tially greater than that in Dolby
ProLogic.
NOTE: The center channel speaker is
not operational in the Theater or
Stadium modes.
