The two switches must be set to the same position for the subwoofer to receive a signal.

WIRELESS TRANSMITTER

WIRELESS SUBWOOFER

– The Wireless Subwoofer could be too far

away from the transmitter to receive a

sufficiently strong signal. Try moving it closer.

A Note Regarding Wireless Performance:

•Connect the left and right front preamp outputs to the left and right inputs of the transmitter.

•Adjust the settings on your receiver as follows: Front Speakers = LARGE

Subwoofer = OFF or NO

ADJUSTING YOUR SUBWOOFER

Note: When you set up your subwoofer for the first time, you will probably have to make adjustments several times before you hear what you personally like.

FINE TUNING YOUR SUBWOOFER

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

•Low Pass Filter Control: NOTE: This control does not operate when the subwoofer is connected with Option #1 (LFE Input). This control, which is located on the back of the amplifier, 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.

•Phase Switch: Playing music and sitting in your listening position, carefully listen for the point at which the subwoofer transitions to your main speakers. This is the crossover point, and this point should be below the frequency of a male human voice. Whichever phase setting sounds louder or fuller at the subwoofer’s crossover point

is the optimum setting. Sometimes no difference will be heard.

Like all wireless devices, your PSWi225 may be susceptible to RF interference from such sources as microwave ovens, WiFi computer systems, video game systems, cordless telephones, blue tooth systems, baby monitors and other devices. In particular, any devices operating in the 2.4GHz band may cause intermittent wireless connections between the PSWi225. It is also possible that your PSWi225 may affect other wireless systems. For the most part, you can avoid wire- less performance problems by physically separating these devices from your PSWi225. Maintaining a distance of several feet or more between your PSWi225 speaker and any wireless device should prevent any mutual interference effects. If you do notice any subwoofer signal dropouts take care to identify the root cause (most commonly having other wireless devices too close) and resolve accordingly. Any interference effects from a microwave oven will cease once the oven stops operating and may be resolved on a long-term basis by increasing the physical distance between your PSWi225 and the microwave oven.
