Cetacea Sound PAS I Presentation Audio System Owner's Manual - Manual (Page 9)

Set Up Instructions
The PAS works best when connected to standard “line level”
computer, LCD, and portable stereo equipment. Be careful
when using a headphone jack from these devices as the input
source. Most have very high distortion when the headphone
volume control is set above 3/4 turn. If it is desired to use the
headphone jack, the best method to adjust for highest quality
sound is to turn the PAS volume control all the way up and
then turn the headphone volume up just until distortion is
heard. Then use the PAS volume control to adjust for best
listening as required. Standard and portable CD players can
be used for demonstration as long as the bass boost is turned
off and the distortion is adjusted as just described. Some of
these portable players, as well as notebook computers, have a
lot of distortion that can be minimized by following these
methods.
Be especially careful of notebook computer sound software.
Set all software controls for volume, bass, and treble to their
midpoints and use the PAS volume control knob to adjust for
total system volume. Turn off all artificial sound effects like
SRS, Spatializer, and DSP’s.
The desktop speakers are designed to have the best frequency
response when placed on a large table or desk top. For best
results, this table top should measure at least .75 meters by 2
meters. If two smaller tables are used each should be at
least .5 by .5 meters. The desk top speakers have a 360 degree sound radiation
pattern. For best results, place them at least 1 meter away from
any vertical wall or surface.
The subwoofer should be placed on the floor near an
intersecting wall directly below and in-between the desktop
speakers. Because each room sounds different, the bass
volume control on the subwoofer may need to be adjusted to
the listener’s preference. In small rooms, the bass control is
usually set between 9 o’clock and noon.
