Model SB-1000 Powered Subwoofer

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.

Many surround sound receivers and processors offer a choice of cross- overs,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 low- est bass frequencies that are in the range where the large main speakers begin to roll off.

Subwoofer Troubleshooting Guide

Once your subwoofer is set up, you should have many years of maintenance free enjoyment from your system. However, if you should encoun- ter a problem, refer to the following guide to help you find the solution. If a problem persists, you should contact your local authorized Atlantic Technology dealer.
