Step 4: Set Audio Receiver Options
It is important to set up the audio receiver to work in concert with the subwoofer. To set up the audio
receiver refer to its instruction manual and use one of the following options:
Audio Receiver Option #1
The audio receiver’s LFE or SUB output is the input to the subwoofer (most common case). Use the
audio receiver’s speaker menu and set as follows:
1.
Select that you have a subwoofer.
2.
Select the number of speakers.
3.
Select the speaker size as small.
4.
If you don’t know the low frequency limit of your main speakers, use 80 Hz as the crossover
point. The lower limit of the main speaker’s frequency response is usually listed in the speaker
specifications. For example, the specs might include an entry similar to the following:
“3 dB down at 45 Hz.”
In this example, double the 45 Hz value and use the 90 Hz doubled-value as the crossover
frequency.
5.
Adjust the LFE /SUB output level to 0 dB.
Audio Receiver Option #2
The audio receiver’s full bandwidth R and L output channels are the input to the subwoofer (less
common case). Use the audio receiver’s speaker menu and set as follows:
1.
Select that you have no subwoofer.
2.
Select the number of speakers.
3.
Select the speaker size as large.
Audio Receiver Option #3
The audio receiver has no LFE or SUB output. You don’t need to make any selections in the audio
receiver’s speaker menu.
