Polk Audio PSW250 instruction manual Option #4, Only

HOOK-UP OPTIONS

OPTION #4

(PSW450 Only) – Not recommended for use with RM6200 and RM6600 systems. The PSW450 offers a “switchable high pass filter” at 80Hz for those situations where you choose to limit the lower bass content directed to your front left and right speakers. The benefit can be greater dynamic range from the front left and right speakers because they are not being asked to produce any bass frequencies below 80Hz.

This hookup would be the same as Option #1, but with the switch turned to “80Hz.” See fig- ure 6. Consult your dealer or Polk Audio cus- tomer service if you have questions about the use of this feature.

AC POWER CONNECTION

AND AUTO ON/OFF

PSW250, PSW350 and PSW450 models sold within North America are designed to be con- nected to 110-120 volt AC outlets.

Units destined for countries outside of North America that use 220-240 volts are factory preset for 220-240 volt operation. If you do not know your local supply voltage, consult your Polk Audio dealer before connecting the amplifier to the supply or to your other hi-fi components.

AUTO MUTE CIRCUIT

The PSW250, PSW350 and PSW450 feature auto on/off circuitry, marked “auto” on the power switch, that automatically turns your subwoofer on when it senses a program sig- nal. 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 sub- woofer in the “on” position.

ADJUSTING THE

PSW250/PSW350/PSW450

•For RM6600 and RM6200 adjustments please refer to their owners manuals.

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

•Low Pass—This control adjusts the fre- quency 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 con- trol 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.

•Phase Switch—Have someone else 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 optimum phase tuning.

MAINTAINING THE APPEARANCE OF PSW SERIES SPEAKERS

Your new speaker cabinet is made of a rugged material that can be dusted or cleaned with a moist cloth. Avoid harsh detergents and cleaning fluids, they can permanently damage your speakers’ finish.

TECHNICAL ASSISTANCE OR SERVICE

If, after following the hook-up directions, you experience difficulty, please double check all wire connections. Make sure that your elec- tronic equipment is operating correctly by hooking up another speaker to the speaker output. For example, if you are not getting sound from the left channel speaker, connect the right channel speaker to the left output. If you still get no sound from that side, the problem is in your amp, receiver or source electronics. Should you isolate the problem to the speaker, contact the authorized Polk Audio dealer where you made your purchase. Authorized Polk Audio dealers are the best source for advice and assistance.
