RECEIVER SET-UP / BASS MANAGEMENT

All surround receivers allow you to “customize” their performance depending on the size of your speakers. Refer to the owner's manual of your

receiver or surround processor to learn how this is done. To get the best performance from small “satellite/subwoofer” type systems, use the

following settings with the above hook-up method:

Front speakers -- set to “large”

Center speaker -- set to “normal” or “small”

Surround speakers -- set to “small”

Subwoofer -- set to “OFF” or “none.” (We know. Doesn’t make sense, right? Your system obviously has a subwoofer. But really truly, this is the

correct setting for the recommended hook-up method. By setting the front left and right speakers to “Large” and routing them through the sub-

woofer as instructed above, you deliver a full range signal to the subwoofer’s low pass filter. The low pass filter directs low frequencies and to

the subwoofer. Full range signal is passed to the front speakers, for perfect sub/sat blending.)

HOOK-UP METHOD #2 (FIGURE 8)

This method can be used with electronics that include a “SUB OUT” feature (Figure 8). It is not recommended for use with compact sub/sat

systems. Connect a single RCA cable from the “SUB OUT” of your electronics to the LFE input of the subwoofer. This input bypasses the sub-

woofer’s variable low pass filter and relies on the filter built into your electronics. If your “SUB OUT” is an unfiltered signal (check your owner’s

manual), use either left or right “Line Level Input,” to use the low pass crossover in the subwoofer. When using method #2, it is necessary to

adjust the settings of your electronics as follows: Front speakers = large or small depending on their output capabilities; Subwoofer = “ON.”

HOOK-UP METHOD #3 (FIGURE 9)

This method is for use with electronics featuring “PRE OUT” jacks—and may be used as a secondary hook up method for use with compact

satellite speakers such as Polk RM Series. Connect the left and right preamp output from your electronics to the left and right LINE LEVEL input

of the subwoofer. This may require use of RCA “Y” cables (not supplied) to hookup both the subwoofer and your power amplifier. When using

method #3, it is necessary to adjust the settings on your preamp/processor as follows: Front speakers = LARGE; Subwoofer = “OFF” or “NO.”

AC POWER CONNECTION AND AUTO ON/OFF (FIGURES 10, 11 & 12)

These PSW series subwoofers feature auto on/off circuitry, marked “auto” on the power switch, that automatically turns your subwoofer on

when it senses a program signal. When no signal is present, the circuit turns the subwoofer off after a few minutes. If you are concerned

about the brief delay between when the music starts and when the subwoofer turns on, simply leave your subwoofer in the “on” position. When

the power switch is set to “OFF” (PSW303 or PSW404) or “STANDBY” (PSW505) it consumes a low amount of power. If this is a concern, you

may want to leave your PSW system unplugged during extended periods of non use, such as during a vacation.

Note (PSW505 owners only): Your PSW505 has a detachable power cord.

SUBWOOFER ADJUSTMENTS (FIGURES 10, 11 & 12)

Your Powered Subwoofer offers a range of setting options. We recommend the following settings as starting points, but the setti

ngs that are

best for you depend upon your speaker placement, electronics and personal taste. After you’ve become familiar with what the settings do,

experiment with alternate options to find the method that works best for your system setup. You’ll find an informative article on “Subwoofer

Positioning and Adjustment” in the set up section at:

“ MAKING ADJUSTMENTS” OR “ FINE TUNING” (FIGURES 10, 11 & 12)

• For RM System adjustments please refer to their owners manuals.

• Volume—Adjust by ear using a wide variety of CDs and video sources. Adjust for deep, powerful bass without “boominess.”

• Low Pass—This control adjusts the frequency range over which the subwoofer operates. When using smaller main speakers, the upper

range of the control will probably yield the best results. With larger speakers, the lower end of the control range will probably sound best,

but always let your ear be the final judge. If male vocals sound “thin,” turn this control up until the voice sounds rich but not boomy. If

male vocals sound too “thick” or “chesty,” turn this control down until the voice sounds natural. NOTE: This control does not operate when

the subwoofer is connected with Method #2 (LFE Input).

• Phase Switch—Have someone switch between the two settings while you sit in your favorite listening position. Use music with good bass

and a deep male vocal. When you hear the best balance of deep bass and natural lower octaves of the male voice, you have achieved opti-

mum phase tuning.
