P/SP-1500 Owner's Manual 11
Volume
You can adjust the Volume from the remote control or on the front panel. The on-screen and front panel
displays indicate the volume level in decibels relative to THX Reference Level and all active channels will
flash for three about seconds each time you change the volume. The volume keys are also used in
conjunction with the Cal and Trim functions (see page 14 and 16).
Input Level Controls and Input Overload Indicator
These remote control adjustments limit the amount of signal sent to the surround processor from your
source components to maximize headroom. You can attenuate the Input level from its maximum of
0 dB to a minimum of -12 dB. Any time the input circuitry is being overdriven, the P/SP-1500 displays
Over on the front panel display and in the upper right hand corner of the on-screen display any time
there is an overload. Set the Input level so the overload indicators flicker only with the highest peak
levels. If the Over indicators flash frequently, reduce the Input level accordingly.
Input Selectors
You can select any of the seven inputs from the remote control or on the front panel. When you select an
input, a green LED on the front panel will illuminate corresponding to the selected input The
on-screen display will show the selected input, mode and input level.
Processing Modes
There are seven processing modes available with your P/SP-1500. All seven modes are accessible from the
remote control while the four most used processing modes are also accessible on the front panel.
Dolby Pro Logic
You can select the Dolby Pro Logic mode from the remote control or on the front panel. This mode
accurately decodes Dolby Surround encoded material to provide multi-channel playback including
dedicated center and surround channels. Most video releases of major movies and many television
programs, compact discs and video games are Dolby Surround encoded. You may use the Dolby Pro
Logic mode on a wide variety of non-encoded material with good results. Most stereo recordings will
produce surround effects to varying degrees, and center channel signals such as vocals will emanate more
naturally from the center channel. All output channels are operative in this mode.
THX Cinema
When you select the THX Cinema mode on the front panel or remote control, the P/SP-1500 engages
proprietary Lucasfilm circuitry along with Dolby Pro Logic processing. These THX processing circuits
include re-equalization, timbre matching, and de-correlation. THX Cinema processing greatly enhances
the film experience by equalizing excess treble mixed into many soundtracks and optimizing the
performance of surround speakers. If you are using THX Home Cinema speakers, you will probably want
to engage the THX Cinema mode for the playback of most film soundtracks. You can choose the THX
Cinema mode from either the remote control or on the front panel.
