SPEAKER PLACEMENT

CINEMA SET UP GUIDE
Typical Loudspeaker Placement

Figure 1 illustrates the most generally accepted speaker locations for a home the-
ater system. Although there are an infinite number of set up options using Figure
1 as a template will certainly provide a great starting point. Experimentation with

slightly different speaker locations may provide improved performance in your
specific listening environment.

The front left and right speakers should form a 45 degree triangle using the center
seating position as the apex.

The surround speakers should be placed beside the listening area, and pointed
towards each other. It is also recommended that the speakers be 2-3 feet above
the listeners head.

Left/Center/Right Front Speaker Height

One of the most important parameters for the left/center/right front speakers in
a home theater system is height. Figure 2 shows the ideal arrangement of the
speakers in relation to the viewing screen: all three speakers are aligned on the
same horizontal plane. This establishes a firm image height when special audio
effects are panned from one side to the other, such as a speeding car moving
across the screen. When a large discontinuity occurs between the heights of the
center front channel and the left/right front speakers, as depicted in Figure 3, the
visual image of the moving object becomes confused and somewhat unnatural
due to shifts in image height.

CARE AND MAINTENANCE

Your speakers are designed to work with a wide range of electronic components.
As little as 20 watts per channel can provide enough power for most applications.
If you have a large room or prefer louder listening levels, more power may be
required.

Caution: When choosing an amplifier, do not exceed the power
rating of the speaker. If you hear very high levels of audible dis­tortion you are exceeding the capabilities of the system. Damage
can occur from this distortion, turn the volume back down until the
distortion disappears.

Use the following guidelines to maintain the appearance of your speakers. Use
a soft, damp cloth to clean the speaker cabinet. Avoid using harsh detergents or
cleaning fluids. Remove the grills to vacuum and remove dust. Do not vacuum
any of the speaker components, permanent damage could occur.

OUTPUTS

SUB

Refer to Figure A

1) Power Switch: This three position switch controls the power status of the sub­woofer.
Off: Turns the unit off.
Auto: Places the unit in the standby mode, in this mode the subwoofer will auto­matically turn on when an audio signal is applied to either the high or low level
inputs.
On: Turns the unit on regardless of whether a signal is present or not.

2) Subwoofer crossover: This rotary control adjusts a variable low pass filter to
set the upper frequency at which the output of the subwoofer begins to roll-off.
Continuously variable from 40Hz to 180 Hz, it matches the upper frequency char­acteristics of the subwoofer to the low frequency response of the main stereo
speakers. Recommended setting 180Hz.

3) Line level input: These RCA phono jacks accept a line level full range signal
from the preamplifier output of a receiver or preamplifier. This full range signal is
processed and amplified to power the subwoofer.

4) Speaker level input: These spring loaded terminals for speaker wire accept a
stereo, speaker level, full range signal from a receiver or power amplifier. This
signal is processed and amplified to power the subwoofer.

5) Fuse: For continued protection replace fuse with same type and size listed.

6) Level control: This rotary control adjusts the level of the subwoofer and is used
to balance its volume with that of the main stereo speakers.

7) Status LED: This two color light emitting diode shows the status of the sub­woofer electronics. "Red" indicates that the amplifier is plugged in and the power
switch is either off or in standby mode with no input signal present. "Green"
indicates that the amplifier is operating with signal present at the input from the
preamplifier, receiver, or power amplifier.

8) Speaker level output: These terminals supply full range signal to the front satel­lite speakers.

WIRING AND CONNECTIONS

Turn off all power to your subwoofer and other equipment before making
any connections.
