Safety Precautions
CAUTION: To reduce the risk of electric shock, do not remove the cover (or back). No user serviceable parts inside. Refer to qualified personnel.
WARNING: To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture. This device generates a fair amount of heat. Make sure nothing blocks the ventilation openings on the top and bottom of the unit.
The lightning flash with arrowhead, with in an equilateral triangle, is intended to alert the user to the presence of uninsu lated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electrical shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating maintenance (servicing) instructions in the literature accompanying the appliance.

Bass Level Control
Use this control to set the level of bass desired
Status LED
This will be green for "on" condition, amber for "standby"
Standby Switch
When in ON position, the amplifier will always be on. When in the
AUTO position, the amplifier will be in Automatic Standby Mode.
Crossover Control
An adjustable (40Hz to 140Hz) @ 18dB per octave low-pass crossover.
Phase Switch
This switch allows precise acoustic matching with satellite speaker systems whose output may be phase reversed. Try in both positions — use the position that results in the strongest bass output.
Crossover Switch
When in the NORMAL position, adjustment of the crossover can be made by the Crossover Control. If being fed a pre-filtered or THX signal, place the switch at the BYPASS position. (pages 5 and 9)

The outputs allow daisy chaining of multiple subwoofers, or as a return path back to the processor.
Low Level Input
Use the input to connect to the subwoofer or LFE line out from your processor/receiver.

Voltage Select Switch
Voltage switch for use in different countries. This switch will be set when you receive the unit. Change this setting only when you are sure your application requires it. For US, the switch should be set to the 115V position.
On/Off Switch
Use this switch to turn the amplifier completely on or off.
AC Input
Use the included power cord to connect your amplifier to a wall outlet.

Placement and Operation
Generally speaking, the best location for your new subwoofer is the front of the room, close to a corner (Figure 5). Every room has its own unique sound characteristics, and flexibility in the exact placement of the subwoofer is always desirable. The closer the subwoofer is placed to a wall and especially a corner, the more and deeper the bass response you will hear. However, in some rooms, corner placement can produce a
“one note” boomy effect. Under such circumstances the subwoofer may work better away from the corner. Experiment to find the best position in your room.

STANDBY
When used with the System 1200 or 2200, the Crossover control should be set at
Many surround sound receivers and processors offer a choice of crossovers, typically between 80 Hz and 120 Hz. If yours does, we recommend using the 100Hz setting when using small speakers such as those in the
System 1200 or 2200. Consult your electronics owner's manual for more details.
Higher crossover frequencies pass more bass but can sound boomy and may be more easily localized to the subwoofer. Higher crossover frequencies may be suitable, however, when using very small satellites that have no real low frequency performance. Settings lower than 80Hz should be employed if you are using larger speakers that have extended bass response. This way, the subwoofer will only reproduce the very lowest bass frequencies that are in the range where the large main speakers begin to roll off.
It’s generally undesirable to have the main speakers and the subwoofer overlap too much. Larger speakers means a lower Low-pass crossover frequency, smaller speakers means a higher Low-pass crossover frequency. Consult the manufacturer’s specified low frequency response for your main speakers to determine the appropriate Low-pass setting on your subwoofer. In the end, however, a little time spent experimenting will generally result in dramatically better bass response.
Care of Your Subwoofer
Your subwoofer is constructed from 3/4” Medium Density Fiberboard.
MDF is a non-resonant material ideal for speaker system enclosures. To clean the cabinet you may use a soft cloth either dry or slightly dampened with clean water. Be careful not to wet the cabinet or allow any water to enter the cabinet seams. Avoid placing your speakers in direct sunlight or near a source of heat that may, over time, damage the finish.
40 Hz 140 Hz goal is to optimize the performance of the system by ensuring that the subwoofer and satellites produce a cohesive and well integrated sound “picture.”
