Surround Modes
When using the Entra Point Five HTS in a Dolby Pro Logic* home
theater system, make sure the receiver's center channel mode is
set to "Normal." When using the system in a Dolby Digital or DTS
home theater system, make sure all speakers are set to "Small" .
Some Dolby Digital-equipped receivers/processors offer different
setup options for each source or surround mode, e.g., CD-stereo,
videotape, Dolby, Pro Logic. In each case, follow your equipment's
instructions to ensure that the subwoofer output is turned on and
that the speakers are set to "Small" in each mode.
Power On
Plug your subwoofer's AC cord into a wall outlet. Do not use the
outlets on the back of the receiver.
Initially set the subwoofer's Level control
position.
Turn on the subwoofer by pressing the Power button
rear panel.
Turn on your entire audio system and start a CD or movie sound-
track at a moderate level.
Important Note: The Entra Sub includes an Auto-On/Auto-Off
circuit. During periods of normal use, the power switch should
always be left on. It should only be turned off during extended
periods of nonoperation, e.g., when you are away on vacation.
Adjust Gain
Turn the subwoofer's Level control
sound emanates from the subwoofer, check the AC-line cord and
input cables.Are the connectors on the cables making proper
contact? Is the AC plug connected to a "live" receptacle? Has the
Power button
been pressed to the "On" position? Once you
have confirmed that the subwoofer is active, proceed by playing a
CD, record or cassette. Use a selection that has ample bass
information.
Set the overall volume control of the receiver/processor to a
comfortable level. Adjust the subwoofer's Level control
you obtain a pleasing blend of bass. Bass response should not
overpower the room but rather be adjusted so there is a
harmonious blend across the entire musical range. Many
users have a tendency to set the subwoofer volume too loud,
adhering to the belief that a subwoofer is there to produce lots
of bass.This is not entirely true. A subwoofer is there to enhance
bass, extending the response of the entire system so the bass
can be felt as well as heard. However, overall balance must
be maintained or the music will not sound natural. An experienced
listener will set the volume of the subwoofer so its impact on
bass response is always there but never obtrusive.
Crossover Adjustments
NOTE: This control will have no effect if the Direct Input is used.
If you have a Dolby Digital or DTS receiver/processor, the Low-
Pass Frequency is set by the receiver/processor. Consult your
owner's manual to learn how to view or change this setting.

until
Low-Pass Frequency Adjustment control
control determines the highest frequency at which the subwoofer
reproduces sounds. For the Entra Point Five HTS, it is recommended
that this control be set at 120Hz.
Phase Control
The Phase switch
determines whether the subwoofer
speaker's piston-like action moves in and out with the main
speakers, 0˚, or opposite the main speakers, 180˚. Proper phase
adjustment depends on several variables such as room size,
subwoofer placement and listener position. Adjust the phase
switch to maximize bass output at the listening position.
Final Positioning
After correctly connecting the Entra system and verifying that
both the subwoofer and all satellite speakers are playing, it is
time to optimize the system for your particular listening room.
Earlier, you placed the subwoofer in its general location. Finding
the exact location for optimum performance sometimes only
involves moving the speakers up to a few inches in any
direction. We urge you, therefore, to experiment with placement,
if possible, until your speakers deliver their full potential.

AINTENANCE AND
The satellite and subwoofer enclosures may be cleaned using a
soft cloth, dampened with water only, to remove fingerprints or
to wipe off dust.
The grilles may be gently vacuumed. Stains may be removed
with an aerosol cleaner, following its instructions. Do not use
any solvents on the grille.
All wiring connections should be inspected and cleaned or
remade periodically.The frequency of maintenance depends on
the metals involved in the connections, atmospheric conditions,
and other factors, but once per year is the minimum.
If a problem occurs, make sure that all connections are properly
made and clean. If a problem exists in one loudspeaker, reverse
the connection wires to the left and right system. If the problem
remains in the same speaker, then the fault is with the loud-
speaker. If the problem appears in the opposite speaker, the
cause is in another component or cable. In the event that your
Entra Point Five HTS ever needs service, contact your local
Infinity dealer or Infinity directly at 1-800-553-3332 (USA only)
or www.infinitysystems.com for a service center near you.
