Configuration
The CP-3 Configuration Menu allows a wide range of choices in speaker
placement and room setups to maintain optimal performance in almost any
room with virtually any speaker system. A table of these menu choices is
shown below.
80Hz HPF Turns on and off the High Pass Filter that removes low frequency
information from the left, center, right, side and rear outputs (12dB per
octave, -3dB at 80 Hz.) Turn ON if you are using THX-certified speakers.
You may also want to turn this control ON if you are using small satellite or
in-wall speakers throughout the system.
Center Select FULL if you have a full-range center speaker, or if you have
set the high pass filter ON.
Use SMALL if your center speaker cannot handle deep bass well. This will
automatically engage the Bass Split parameter in the Preset surround
modes that use the center, splitting bass out of the center channel and
directing it to the main left and right outputs.
Select NONE if there will be no center speaker in the system.
NOTE: The center output is only active in the surround modes, not in
Panorama, Ambience or Reverb.
Sides Select THX if THX-type surround speakers are used for the sides.
Select STANDARD if any other type of speakers are used, and NONE if
there are no side speakers in the system.
NOTE: THX -type surround speakers provide good diffuse envelopment
with only two speakers. Additional surround speakers will color the
surround information through comb-filtering effects. To prevent this, if
THX side speakers are selected in the Speaker Configuration menu, the
rear channels are muted in THX mode.
Rears Select the appropriate setting for the number of rear speakers in the
system. If you are using only a single rear speaker, or multiple speakers with
a single amp channel (mono), select ONE. This speaker should be connected
to the left rear output on the CP-3 rear panel. Select TWO if you are using
two or more rear speakers.
Subwoofers Select YES if you are using the SUBWOOFER output. (See
page 26.)
