Theater Compensation
Theater compensation provides special equalization
within any of the selected DSP modes. Most theatrical
soundtracks are mixed on large dubbing stages for play-
back in large movie theaters. When these soundtracks are
played back in your home, they may appear to have too
much treble, sounding harsh and “bright.” Theater com-
pensation modies the audio signal to reduce these char-
acteristics and make the soundtrack reproduction more
natural sounding.

Dolby Pro Logic II Cinema and DTS-ES NEO:6 Cinema
include a form of equalization of their own to address the
same conditions. When using these modes the addition
of theater compensation may cause excessive reduction
of the upper frequencies. However, you may wish to
experiment with different soundtracks to nd what sounds
best to you.
Important Note: Theater compensation is not recom-
mended for music modes, as the equalization added is not
normally needed.
Analog Level Input and Peak Indicator
Not all consumer products (CD players, DVD players, etc.) reach
a 2V RMS output, therefore the analog input level needs to be
adjusted to meet such requirement before being processed.
Adjustments are made in 1dB steps from -15dB to +10dB and do
not affect any of the analog direct inputs.
Should the input signal overload the analog to digital
convertor, the word “peak” will start ashing after “anlg
peak ind:” until the user turns down the input signal via
the master volume knob or left/right selector (when in the
system cong menu).
