WEEE NOTICE

Note: This mark applies only to countries within the European Union (EU) and Norway.
This appliance is labeled in accordance with European Directive 2002/96/EC concerning waste electrical and electronic equipment (WEEE). This label indicates that this product should not be disposed of with household waste. It should be deposited at an appropriate facility to enable recovery and recycling.

VOLUME CONTROL

This control affects the output of your subwoofer, and should be set at lowest level before turning the power on. Volume can be increased until desired level is achieved. For 2-channel applications, you should adjust the volume to match the output of your speakers.

UNPACKING

Place the package on the floor or table top with the box flaps up. Cut the tape with a utility knife to open the package. Fold the carton flaps back and carefully slide the subwoofer and packaging from the box, or turn the box over with flaps open and remove the box. Stand the subwoofer and packing upright, making sure the subwoofer is right side up, and remove the packing material.

CONNECTING YOUR SUBWOOFER

Ensure that the subwoofer is unplugged from power source (wall outlet) before making any connections to your amp/receiver.

LFE CONNECTION

Connect RCA connector from LFE output on your amp/reciever to LFE input on subwoofer

LEFT/RIGHT PREAMP OUT

If there is no LFE output on your amp/receiver, you can use the left and right preamp outputs to connect to the left and right inputs on your subwoofer.

POWER SWITCH/AUTO/ON

The POWER ON switch near the bottom of the panel supplies power to the sub amplifier. When the AUTO/ON switch is in the AUTO position, the subwoofer will automatically turn on when it senses a signal. The subwoofer will automatically go into standby mode after 15 minutes with no signal. When this switch is in the ON position, the subwoofer will remain on.

CROSSOVER

This control affects the upper frequency limit of the subwoofer. The control range is 40-180 Hz, along with a disable (LFE) setting. The slope of the low pass filter is 12 dB/octave. For connection to an A/V receiver, the low pass should be set to LFE. For 2-channel applications, it should be adjusted to blend with the bottom roll-off frequency of your loudspeakers.

VOLUME CONTROL

This control affects the output of your subwoofer, and should be set at lowest level before turning the power on. Volume can be increased until desired level is achieved. For 2-channel applications, you should adjust the volume to match the output of your speakers.

PHASE CONTROL

This control delays the signal being processed through the amplifier. For connection to an A/V receiver, it should be set to 0 degrees. For 2-channel systems, it should be adjusted to obtain optimal transition between the loudspeakers and the subwoofer, and best sound stage

ROOM POSITION

The placement of your subwoofer can add a significant difference to the performance of your home theater system. Low frequencies are omni directional, but best performance results if you place the subwoofer in the corner, as this will increase the level of bass output. You can experiment with different configurations, or even add multiple subwoofers to your system (see diagram).

NOTE: When cleaning your subwoofer, avoid the use of abrasives, solvents, or harsh detergents. Windsor subwoofers have a long-lasting vinyl finish that should only require dusting or cleaning with a dry cloth. Gently use the brush attachment of your vacuum cleaner to remove any dust or particles from the surfaces of your subwoofer
